Tooth decay: what it looks like, why it occurs and how it is treated

Caries: what it is and what causes it

Caries is a complex infectious disease characterized by demineralization and gradual destruction of hard tissues (enamel and dentin). The process is activated under the influence of specific bacteria of the Streptococcus mutans group, which process carbohydrate residues into aggressive organic acids.

The main factors in the development of pathology are poor hygiene, excess sugar in the diet and a deficiency of important trace elements, such as fluorine and calcium. Statistics show that the disease is diagnosed in 95-98% of the adult population, and the rate of spread depends on the viscosity of saliva and the individual resistance of the enamel. Scientific studies confirm that in the absence of preventive measures, the initial lesion turns into a carious cavity within 6-12 months. Such rapid progression requires regular monitoring of the condition of the oral cavity by a specialist.

What does tooth decay look like and what are its first signs

The initial manifestations of the disease often go unnoticed, as they are not accompanied by pain due to the lack of nerve endings in the enamel. It is important to detect the problem at a stage when the tissues can still be restored without radical intervention:

• Discoloration: the appearance of white, chalky or dark spots on the enamel, which indicates the loss of minerals.
• Sensitivity: a short-term reaction to sweet, cold or hot, lasting only a few seconds.
• Textural changes: a noticeable roughness of the surface when in contact with the tongue.
• Discomfort during eating: especially if caries develops between the teeth, which causes food fibers to get stuck and irritate the gums.
• Appearance of odor: a specific unpleasant odor from the mouth (halitosis), caused by the decomposition of organic residues in the carious cavity.

The combination of several of the listed signs is a direct indication for a professional examination and X-ray examination. Only a comprehensive approach allows us to differentiate carious lesions from other non-carious enamel defects, such as hypoplasia or fluorosis.

Stages of caries: from spot to deep lesion

The development of the disease is classified by the depth of tissue damage, which directly affects the choice of therapy method and the complexity of restoration. The earlier the pathology is detected, the greater the percentage of healthy tissues can be preserved during treatment:

1. Initial stage (white spot): enamel loses minerals, but its structure is still intact, the surface remains smooth. Usually treated with remineralization and deep fluoridation methods.
2. Superficial caries: destruction is limited to the boundaries of the enamel layer, forming a small defect that is easily treated conservatively.
3. Medium caries: the pathological process penetrates the upper layers of dentin, causing regular pain from chemical and thermal stimuli.
4. Deep caries: the destruction reaches the deep layers of dentin, leaving only a thin partition to the pulp chamber, where the nerve is located.
5. Specific localizations: caries of the anterior teeth occurs, which requires high aesthetics of restoration, or cervical treatment of which is complicated by proximity to the gingival margin.

The treatment of interdental caries requires special attention, since it is often hidden from visual inspection and is detected only with the help of a targeted image. Timely detection of hidden cavities allows you to avoid sudden destruction of large volumes of the crown part.

How to treat caries: modern methods of dental treatment

Thanks to innovations in dentistry, treatment is no longer associated with discomfort and pain. Modern protocols are aimed at maximum microinvasiveness and painlessness of each manipulation. The main trend of recent years is laser caries treatment, which allows you to selectively vaporize the infected areas without the mechanical effect of a standard bur. This method eliminates the appearance of enamel microcracks, ensures high sterility of the cavity and improves adhesion of the filling material. For standard clinical cases, dentists use photopolymer composites, which are completely identical to natural tissues in terms of strength, transparency and color. The doctor offers an individual plan that includes thorough cleaning under a microscope, antiseptic treatment and anatomical restoration of the chewing surface.

Treatment of caries in children and whether it hurts to treat a tooth

Many parents are concerned about the advisability of intervention in temporary teeth, since they are then replaced by permanent ones. However, caries on milk teeth progresses much faster due to the low density of enamel and the large volume of the pulp chamber, which threatens to damage the rudiments of permanent teeth. Treatment of children requires a specific approach adapted to the psychological state of the small patient and anatomical features. The rate of spread of infection in children is higher, so wait-and-see tactics are unacceptable here:

• Minimal invasiveness: the use of hand tools and special gels to soften carious tissues.
• Colored fillings: the ability to involve the child in the process of choosing a material, which removes the psychological barrier.
• Adaptation visit: the first visit is carried out in the form of acquaintance without treatment to build trust in the doctor.
• Fluoridation: strengthening enamel after treatment to prevent relapse of the disease.

To the question of whether it is painful to treat caries, modern dentistry gives a negative answer thanks to the use of multi-stage anesthesia. The use of application gels before injection and ultra-thin needles makes the anesthesia process imperceptible to the patient. In cases of dentophobia or the need for extensive treatment in one visit, medical sleep is used under the supervision of an anesthesiologist. This approach ensures the absence of psychological trauma in the child and allows the doctor to perform the work as efficiently as possible.
