Dentist: dental and oral treatment

A dentist is a physician who prevents, detects, and treats diseases of the teeth, gums, oral mucosa, and maxillofacial region. Oral health affects nutrition, sleep, speech, productivity, and quality of life, and is also associated with overall health risks, including diabetes and cardiovascular complications. According to the World Health Organization, oral diseases remain the most common noncommunicable diseases, affecting an estimated 3.5–3.7 billion people. This is a significant, but largely preventable, burden. [1]

Most dental problems—caries, inflammatory periodontal disease, enamel erosion, and mucosal lesions—develop gradually and remain asymptomatic for a long time. Therefore, regular checkups and timely professional hygiene allow for early detection of changes, when treatment is simpler, less expensive, and less traumatic. [2]

Comprehensive approaches are important for prevention: dietary sugar control, effective home hygiene with fluoride, professional hygiene, and individualized visit interval plans based on personal risk. This risk-based approach is supported by national and international guidelines. [3]

For many people, fear, embarrassment, or uncertainty about the safety of procedures remain barriers to dental treatment. Modern dentistry relies on advanced anesthesia methods, strict infection control protocols, and gentle restoration technologies, allowing for comfortable and predictable treatment. [4]

When to see a dentist: warning signs and warning signs

It's not just pain that requires a dental checkup. A persistent bad odor, bleeding gums when brushing, sensitivity to cold or sweets, dark spots or chipped enamel, tooth mobility, occasional ear congestion, clicking or joint pain when chewing are all reasons to seek a targeted diagnosis. These symptoms are often associated with caries, gingivitis, or early periodontitis and are more treatable in the early stages. [5]

There are situations when delay is imperative: acute, progressive inflammation, soft tissue or facial swelling, difficulty swallowing, fever, tooth trauma with displacement or complete knockout, or trauma with a suspected jaw fracture. If a permanent tooth is completely knocked out, it's important to keep it moist in milk or contact lens solution and see a dentist as soon as possible—this increases the chances of successful replantation. International guidelines for dental trauma can help. [6]

Even in the absence of complaints, scheduled visits are necessary to adjust home hygiene and diet to the individual's risk of caries and periodontitis. Intervals between examinations should be determined individually: for some, 12-24 months is sufficient, while for those with a high risk, 3-6 months is sufficient. This approach, with individualized intervals, is enshrined in national clinical guidelines. [7]

Below is a brief reminder of typical situations.

Table 1. Signals and actions before the visit

Situation	What could this mean?	What to do at home	When to go
Bleeding when cleaning	Gum inflammation due to plaque	Soft toothbrush, brushing thoroughly along the gum line, floss or interdental brushes	Within 2-4 weeks, if it does not go away - sooner
Acute pain, swelling	Pulpitis, abscess	Nonsteroidal anti-inflammatory drugs, cold on the cheek, do not heat	Urgent in the next few hours
Sensitivity to cold	Erosion, recession, early caries	Soft toothbrush and toothpaste for sensitive teeth	Within 1-2 weeks
Knocked out permanent tooth	Injury	Keep the tooth moist, do not touch the root	Urgent, preferably within 1 hour

Prevention that works: fluoride, sealants, hygiene, and water

Fluoride remains the cornerstone of caries prevention. For adults and most adolescents, toothpastes with 1,350-1,500 ppm fluoride are recommended. For children, depending on age and risk, 1,000 ppm is recommended from the time the first teeth appear, a small "smear" dose up to age 3, and a "pea-sized" dose from age 3 to 6. After brushing, it's best to spit out any excess, but avoid rinsing your mouth to allow the fluoride to work longer. These dosages and techniques are reflected in clinical guidelines for prevention. [8]

Fluoride varnish containing 5% sodium fluoride, equivalent to 2.26% fluoride ion, has been shown to reduce the incidence of dental caries in children and young schoolchildren. It is applied with a brush to dry tooth surfaces, sets quickly, and releases fluoride locally. Its effectiveness has been confirmed by systematic reviews and recommendations from preventive services. [9]

Fissure sealants for posterior teeth reduce the risk of caries in children and adolescents with vulnerable fissure morphology. Sealant application is a painless procedure that mechanically seals deep grooves. Evidence of effectiveness is long-term. [10]

Fluoridation of drinking water at an optimal level of approximately 0.7 mg/L is associated with a reduction in dental caries at the population level. Public health authorities recognize the significant public benefit, while respecting local epidemiology and context. Decisions on water fluoridation are made at the national and regional levels, taking into account the balance of benefits and risks. [11]

Table 2. Fluoride products and when to choose them

Means	Typical concentration	Who benefits?	Comment
Toothpaste for adults	1,350-1,500 ppm	Most adults and teenagers	Do not rinse your mouth after brushing.
Toothpaste for children	1,000 ppm from the first teeth	Children from the moment of teething	Quantity - "smear" up to 3 years, "pea" from 3 to 6 years
Fluoride varnish	2.26% fluorine	Children, high-risk individuals	Applied by a specialist 2-4 times a year
Rinsing solution	0.05% daily or 0.2% weekly	Adolescents and adults at high risk	Addition to pasta, not instead
High fluoride toothpaste	5,000 ppm as directed	Adults at very high risk	By prescription and under supervision

At-home interdental cleaning enhances the effectiveness of a toothbrush. Studies show that adding floss or interdental brushes to daily brushing can reduce gum inflammation and plaque, with interdental brushes often more convenient and effective in spaces between teeth. In tight spaces, floss remains a useful option. Technique and consistency are key. [12]

Table 3. Interdental cleaning: what to choose

Situation	Fits better	Why
There are gaps between the teeth	Interdental brushes	More contact area, simpler technology
Very close contacts	Dental floss	It goes where a brush can't go.
Orthodontic structures	Irrigator plus brushes	Comfort around arches and braces
Limited motor skills	Thread holders or rubber brushes	Less demanding on technology

How often to come: intervals for examinations and professional hygiene

There are no universally applicable intervals. They are determined individually based on a combination of factors: previous caries, rate of plaque and tartar formation, diet, medical conditions and medications, quality of home hygiene, and access to fluoride. Guidelines recommend intervals ranging from 3 to 24 months, more frequently in high-risk patients and less frequently in stable patients. This risk-based schedule increases efficiency and reduces unnecessary visits. [13]

Professional hygiene includes scaling and biofilm removal, polishing, and care training. More important than frequency are the quality of home hygiene between visits and the use of fluoride. In cases of active periodontal disease, the plan will be more specific, with more frequent maintenance visits until stabilization occurs. [14]

Radiographic monitoring is prescribed based on indications, not "on a schedule." Images are taken when the expected diagnostic benefit outweighs the very low radiation exposure, and when the results influence treatment decisions. This is the general principle of the judicious use of radiological diagnostics. [15]

Table 4. Approximate inspection intervals by risk level

Risk level	Doctor's examination	Professional hygiene	Additionally
Short	12-24 months	12-24 months	Training, paste from 1,350-1,500 ppm
Average	6-12 months	6-12 months	Fluoride varnish when indicated
High	3-6 months	3-6 months	Fissure sealants, high-fluoride pastes by purpose

X-ray diagnostic safety: what has changed and what to expect

Digital dental radiography delivers very low radiation doses. For reference, four targeted "bytewing" images are on the order of thousandths of a millisievert, significantly lower than the natural annual background radiation. Comparison tables from regulatory agencies show that dental doses are orders of magnitude lower than those found in many medical studies. [16]

In 2024, the American Dental Association updated its safety recommendations: routine use of lead aprons and thyroid shields is no longer recommended in justified studies, as modern equipment and collimation provide minimal extra-beam dose, and shielding can interfere with imaging and lead to repeated exposures. The key principle is to schedule imaging based on clinical need and minimize dose through technical means. [17]

The choice of examination type depends on the clinical task: targeted and "bytewing" images are for caries and contact surfaces, panoramic images are for general assessment, and cone-beam computed tomography is for complex cases of implantation, endodontics, and trauma. The principle of reasonable use and "as much as needed" applies here. [18]

Your safety is ensured not only by the low dose, but also by infection control protocols in the office: surface treatment, sterilization of rotary instruments, hand hygiene, checking of water systems of installations - these are “basic expectations” for any dental practice.[19]

Table 5. Approximate doses and practical conclusions

Study	Dose assessment	What does this mean for the patient?
Four "bytewings"	~0.004-0.005 mSv	Very low, frequency is determined by clinical need
Panoramic photo	Low dose	Overview information, does not replace sighting contacts
Local cone beam tomography	Typically higher than targeted images, but lower than many medical CT scans	Prescribed strictly according to indications, with collimation and the “minimum is sufficient” protocol

Anesthesia and sedation: comfort and risk management

Modern local anesthesia with articaine, lidocaine, and their analogs provides reliable pain relief. The choice of anesthetic and the presence of a vasoconstrictor component are determined by the task and associated conditions. In cases of anxiety and a low pain threshold, sedation techniques are used under the supervision of a trained team, with monitoring and preliminary risk assessment. [20]

Sedation can range from minimal with continued contact, moderate with drowsiness, or deep, up to general anesthesia in a hospital setting for strict indications. Standards emphasize staff training, airway safety algorithms, and mandatory monitoring. This makes the procedures tolerable even for patients with severe dental phobia. [21]

After treatment, acute pain is most often managed without opioids. Recommendations suggest nonsteroidal anti-inflammatory drugs (NSAIDs) alone or in combination with acetaminophen, which demonstrate superior efficacy and safety profile compared to opioid analgesics after standard dental procedures. [22]

Dosages are individually adjusted, taking into account contraindications to nonsteroidal anti-inflammatory drugs and acetaminophen, interactions with other medications, and concomitant illnesses. Patients are given a written treatment plan for the first few days and advice on non-drug measures, such as local cold applications, a gentle diet, and careful hygiene. [23]

Table 6. Post-treatment pain relief: what to choose

Situation	First line	When to strengthen
A little pain after the filling	Nonsteroidal anti-inflammatory drugs as needed	Add acetaminophen if the effect is insufficient.
Removal of an impacted wisdom tooth	A combination of nonsteroidal anti-inflammatory drugs with acetaminophen on a 24-72 hour schedule	Consider a short course of prescription medications in selected patients
Contraindications to nonsteroidal anti-inflammatory drugs	Acetaminophen in a safe daily dose	Consultation for alternatives and non-pharmacological measures

Antibiotics: When are they really needed?

For dental caries-related pain and pulpal inflammation, the first line of treatment remains dental intervention—removal of infection from the source and drainage—rather than antibiotics. For uncomplicated odontogenic pain and localized abscesses without systemic signs, antibiotics do not improve outcomes and carry the risk of resistance and side effects. This is reflected in the guidelines for antibiotic therapy for emergency pulpal and periapical conditions. [24]

Antibiotics are indicated for signs of infection spread, systemic reactions, immunodeficiencies, and other complicating factors, as well as after drainage if there is a high risk of progression. The choice of drug, dosage, and duration depend on local protocols and the individual patient profile. [25]

Patients are advised that pain relief and addressing the underlying cause provide faster and more reliable results than simply "masking" symptoms with antibiotics. This approach reduces antibiotic overload and helps control bacterial resistance at the population level. [26]

Prevention of infective endocarditis during dental procedures

Most people do not require antibiotic prophylaxis before dental procedures. It is recommended for a select group of patients with the highest risk of adverse outcomes from infective endocarditis: for example, those with prosthetic valves, prior endocarditis, certain congenital defects, and heart transplants with valvular disease. A full list and schedule are provided by specialized cardiology guidelines. [27]

The key point is that daily oral hygiene is more important than any one-time preventative measure: it is constant gum inflammation that creates multiple episodes of bacteremia in everyday life. Therefore, attention is paid to plaque control, periodontal treatment, and care training. [28]

Filling Materials and the Environment: What's the Deal with Amalgam?

Composite materials, glass ionomers, and hybrid solutions are widely used today. A number of countries are gradually reducing the use of dental amalgam for environmental reasons. The European Union has approved further restrictions, phasing out amalgam, while allowing for limited exceptions for medical reasons. These decisions are consistent with the international mercury phase-out convention. [29]

For the patient, this means that for most clinical cases, there are aesthetic and durable alternatives without the use of amalgam. The choice of material is determined by the physician based on the load, location, and humidity of the work area, as well as the patient's expectations. [30]

Special situations: children, pregnancy, chronic diseases, elderly

In children, prevention begins with the eruption of the first teeth: fluoride toothpaste in the correct amount, parental care training, sealants as indicated, and fluoride varnish. Fluoride supplements are also recommended for children over 6 months of age if the fluoride level in the water is insufficient, and regular application of fluoride varnish to baby teeth. [31]

During pregnancy, preventive, diagnostic, and therapeutic interventions are considered safe. Local anesthesia with adrenaline may be administered if necessary, and X-rays may be performed if clinically indicated using modern dose-reduction techniques. Delaying necessary treatment is not recommended. [32]

Diabetes and other chronic diseases increase the risk of inflammatory periodontal disease and impair tissue healing. Therefore, dental visits are scheduled more frequently, and home hygiene is especially meticulous. Controlling blood sugar, quitting smoking, and adjusting medications improve dental outcomes and overall health. [33]

For older adults, the challenges of xerostomia due to medications, motor difficulties, and dentures are additional. Family support, the use of comfortable interdental products, and toothpastes with high fluoride concentrations as prescribed help reduce the risk of root caries and inflammatory complications. [34]

Table 7. Age and clinical emphasis on prevention

Group	Key measures	Additionally
Young children	Toothpaste with 1,000 ppm fluoride from the first teeth, parent training	Fluoride varnish, sealants according to indications
Teenagers	Toothpaste with 1,350-1,500 ppm, interdental cleaning	Fluoride solutions for high risk
Pregnancy	Prevention and treatment without delay, local anesthesia as indicated	Modern X-ray for strict indications
Elderly	Xerostomia control, sensitivity aids	High fluoride toothpastes by purpose

What to Expect at Your Appointment: Safety Standards and Steps

A typical examination includes collecting complaints and anamnesis, assessing hygiene and gums, examining enamel and bite, and, if necessary, taking x-rays. A plan is then developed: prevention and education, treatment of the causes of pain, restoration of defects, and a maintenance schedule. This algorithm ensures transparency and saves the patient's resources. [35]

Basic infection control expectations are in place in the office: hand sanitization, personal protective equipment, instrument sterilization, water quality monitoring in the unit, and surface cleanliness. This reduces the risk of clinical infections and ensures safe treatment. [36]

First aid before a visit for dental injuries

If a tooth is chipped without pain, keep the broken fragment in a moist environment and schedule an appointment as soon as possible. If a tooth is displaced, do not attempt to force it back into place. If a permanent tooth is completely knocked out, keep the root intact, store the tooth in a moist environment, and see a dentist as soon as possible; the ideal window is within the first hour. These steps increase the chance of saving the tooth. [37]

Table 8. Actions in case of injury

Situation	First steps	It is forbidden
Chipping without pain	Keep the fragment moist and away from hot and cold.	Ignore for more than 1-2 weeks
Bias	Gently stabilize with soft tissues, do not chew on the side	Forced reduction
Knocking out a permanent tooth	Keep the tooth in a moist environment and see a doctor as soon as possible.	Touching the root, drying the tooth

A short checklist for the patient

1. Brush your teeth twice a day with a fluoride toothpaste of the appropriate concentration; do not rinse your mouth after brushing. Supplement with daily interdental cleaning. [38]
2. Reduce the frequency of sugary snacks and drinks. Use fluoride varnish and sealants as directed. [39]
3. Visit your dentist according to your individual risk plan, usually ranging from 3 to 24 months. [40]
4. Don't be afraid of X-rays when prescribed according to indications: the doses are extremely low, and the examination helps make the right decision. [41]
5. For pain relief after procedures, nonsteroidal anti-inflammatory drugs with acetaminophen are preferred on a scheduled basis unless contraindicated. [42]

Who is a dentist?

Dentistry is a very important, widespread, and in-demand medical profession. Diseases of the teeth, gums, jaws, and oral mucosa are all within the purview of a dentist. They can prescribe and implement therapeutic or preventative measures, conduct additional examinations, and perform restorations and prosthetics.

To become a dentist, you must obtain a higher medical education in a dental specialty. This education can be provided by a medical academy or university. After completing this education, future specialists will also need to complete an internship, after which they can begin practicing dentistry.

Dental specialists can work both in private structures and in public clinics.

A dentist has the right to conduct private practice, serving patients in his own dental office, or to engage in scientific work and subsequently become a candidate or doctor of medical sciences.

When should you see a dentist?

The following conditions require a dentist consultation:

• Uncomplicated dental caries – demineralization of tooth enamel followed by the formation of a cavity. The process can be superficial, moderate, or deep;
• complicated course of caries – development of pulpitis or periodontitis;
• periodontosis – pain, looseness of teeth, loss of teeth;
• signs of gingivitis, periodontitis;
• phenomena of fluorosis.

Simply put, a visit to the dentist is necessary:

• for toothache;
• if teeth or gums are hypersensitive to hot or cold, sour or sweet foods;
• in case of traumatic damage to teeth or gums;
• in case of excessive bleeding of gums;
• in case of swelling of the gum area, suppuration, pain when pressing and biting;
• when the shape and color of the tooth changes, or spots appear;
• if bad breath appears;
• in case of loosening or loss of a tooth;
• when cracks and chips appear on the enamel;
• for ulcers and pigmentation of the oral mucosa.

What does a dentist do?

Modern dentistry includes the following areas:

• Dental therapy. This includes treatment of caries, root canals, fillings, and enamel buildup;
• Periodontology. This is the treatment of inflammatory processes in the gums surrounding and adjacent to the teeth: it includes the treatment of gingivitis, stomatitis, periodontitis, periodontosis, etc.
• Surgery. Includes surgical treatment methods: tooth or cyst extraction, curettage of cavities, and drainage of purulent lesions;
• Dental orthopedics. Deals with prosthetics;
• Orthodontics. Aimed at correcting bite defects;
• Pediatric dentistry. Involves working with children.

A dentist must have an excellent understanding of the anatomical and physiological characteristics of the human body, possess knowledge of the structure of the maxillofacial system and the oral cavity, and be competent in dental materials, medications, and related instruments and equipment.

What diseases does a dentist treat?

General dentists treat caries and root canal pathologies at various stages of tissue damage.

Specialists can treat inflammation of the oral mucosa, tissues, and gums. Periodontal disease, a common condition caused by infection between teeth, is also a dentist's responsibility. This condition, periodontosis, is characterized by pain and bad breath; if left untreated, it can lead to the loss of affected teeth.

The specialist's goal is to eliminate the source of infection and preserve the health of the teeth and gums. However, sometimes, when conventional treatment is no longer effective, a tooth must be extracted. This is also performed by a dentist, who also removes cysts and purulent lesions in the oral tissues.

If a damaged tooth is beyond repair, a dental prosthetist can help. They take measurements, fit, and secure the prosthetics. Their expertise includes crowns, bridges, implants, and removable dentures.

Correction of bite defects is carried out by selecting a brace system or mouth guards.

The dentist also monitors the development of the child's jaw and dental system, treats baby and permanent teeth, and ensures the formation of a correct bite.
