Tooth remineralization

Tooth remineralization is a preventive and therapeutic approach to dental treatment.

Under the influence of various factors, human tooth enamel gradually deteriorates. However, there are ways to stop this process — one of them is tooth remineralization. This treatment is effective for both children and adult patients.

Tooth enamel is the hardest tissue in the human body. This characteristic is due to its composition — about 96% of it consists of minerals, mainly calcium and phosphorus. Its durability depends on environmental factors such as saliva, the presence of dental plaque, and the type and frequency of food and drink consumption.

Enamel loses its stable structure under the influence of acid and changes in oral pH. To some extent, a drop in pH is compensated by the buffering capacity of saliva, which is rich in calcium and phosphorus compounds that penetrate through the enamel. However, at a pH level of 4.5–5.5, enamel becomes damaged — its structure begins to dissolve, leading to subsurface demineralization (loss of minerals). This is the first stage of caries development, known as a white “chalky” spot. Clinically, such changes appear as white, dull, and opaque spots of varying size and location. At this stage, the outer layer of enamel remains intact thanks to the restorative properties of saliva. The white “chalky” spot is the only condition that is reversible up to a certain point. However, enamel remineralization must be performed as soon as possible; otherwise, further caries development will occur.

Tooth remineralization and the risk of caries

In patients with a low risk of caries, the demineralization processes that occur due to daily pH drops in the oral cavity are compensated by the remineralizing effect of saliva. However, if factors that increase the risk of caries appear, this balance will be disrupted. These factors include:

• neglecting proper and regular oral hygiene;

• poor nutrition (consumption of sugar, acidic and carbonated drinks, frequent snacking);

• harmful habits such as smoking and alcohol consumption.

Remember that just a few minutes after brushing your teeth, saliva covers their surface, creating a thin film. Bacteria living in the oral cavity attach to it, including those that can destroy teeth (cariogenic bacteria). This is how dental plaque forms.

Cariogenic bacteria feed on sugars present in the diet. By metabolizing them, they produce acids that damage the enamel prisms. The first stage is enamel damage, followed by dentin involvement. Therefore, it is important to brush your teeth regularly twice a day using toothpaste and to limit sugar consumption.

Tooth enamel remineralization is the process of reintroducing lost minerals into the subsurface layer. This stops the pathological process, and the caries lesion becomes inactive. This is achieved through the use of remineralizing agents.

Changing the oral environment is equally important. In cases of poor hygiene, improper nutrition, or salivation disorders, the process of enamel remineralization becomes difficult and may prove ineffective.

Tooth remineralization at the “SA-NATA” network of clinics — how to strengthen enamel at the dentist’s office

When a white carious spot appears, the dentist has several types of remineralizing agents at their disposal:

• fluoride-based;

• non-fluoride;

• mixed formulations.

Fluoride has a proven remineralizing effect supported by research. It can be applied in the dental office in the form of varnishes, foams, or gels. Non-fluoride agents act synergistically with fluoride, and some demonstrate even higher effectiveness when combined with fluoride ions. The use of fluoride is determined strictly based on individual clinical indications, which can only be assessed by a specialist.

Among enamel remineralization products, many patients are familiar with the so-called “liquid enamel,” often referred to as artificial enamel. However, note that an allergy to milk is a contraindication for its use. Additionally, ozone therapy provides supportive benefits — ozone treatments reduce the number of cariogenic bacteria and, when combined with fluoride prophylaxis, promote enamel remineralization.

Keep in mind that the tooth remineralization procedure is effective only if decalcification is limited to the enamel. Using modern diagnostic tools, only a dentist can determine whether the lesion is suitable for remineralization and choose the optimal treatment method.

Remineralization is supported by the following:

• regular removal of dental plaque twice a day using a toothbrush and dental floss;

• use of fluoride toothpaste with a proven remineralizing effect (as recommended by your dentist);

• use of fluoride mouth rinses (also prescribed by a specialist);

• proper nutrition — limiting sugar, acidic foods, and beverages;

• avoiding harmful habits (especially smoking).

If necessary, the dentists at the “SA-NATA” clinic can recommend additional remineralizing products for home use.
