Caries prevention and treatment

Causes and symptoms of cavities? How to prevent and treat cavities in children?

What is caries?

Tooth decay is a degenerative disease of dental hard tissues (enamel and dentin) that originates from the surface and grows deep into the tooth pulp. Caries does not give major symptoms until the advanced stage, when the tooth begins to hurt.

It is prevention that is the first treatment for caries.

Caries arises from the disruption of the balance of the bacterial flora normally present in the mouth. The bacteria in plaque use sugars from food to survive and at the same time produce acidic waste substances, which are capable of causing injury to tooth enamel. If plaque is not carefully removed, these lesions, initially reversible, can evolve to generate a cavity in the tooth.

The symptoms of tooth decay

Usually caries does not cause symptoms and can only be diagnosed during a checkup.

Symptoms begin to appear in the advanced stage, when caries reaches the pulp, causing structural destruction of a portion of the tooth.

Symptoms may be:

  • pulsating, sharp pain;

  • pain on chewing;

  • pain caused upon eating sweet, very hot or very cold foods.

Sometimes, it is possible to notice for oneself the signs of caries on the teeth, especially on the front teeth, which are more accessible and easy to see, such as: holes, brown or black spots.

The causes of caries

A number of factors must coexist for caries to develop:

  • presence of bacteria capable of producing acids that alter tooth structure;

  • availability of sugars in the diet that promote bacterial growth and adhesion;

  • genetic factors that erode tooth strength and promote bacterial growth;

  • tooth quality;

  • the shape of the tooth and arch;

  • the characteristics of saliva.

Preventing caries with sealants


Sealing is a dental treatment that prevents caries. It is generally performed on permanent molars, the teeth most at risk because they present deep grooves and are the most difficult to clean well with a toothbrush. We use specific non-toxic resins for sealings.

Why perform a sealant?

It is a quick and painless treatment, a good ally for preventing tooth decay in the future.

How is the sealing performed?

Sealing is quick, simple and painless. It starts with a deep cleaning of the grooves of the permanent molars. Then a deep cleansing with a blue paste and, finally, varnishing with a liquid resin, the sealant.

What is the durability of the sealant?

A good sealant done properly provides protection from caries for many years, and if the sealant becomes damaged, the procedure can be repeated.
