Molars and premolars: vulnerable teeth
A full set of adult teeth has 32 teeth (including wisdom teeth) of different types, which differ in shape, function and when they come in. Among them are the premolars and molars, the large flat teeth on the sides and towards the back of the jaws that we use to chew food. These teeth, which erupt gradually until the end of childhood, also have deep pits and grooves where food can easily get stuck. They are therefore exposed to the bacteria that feed on this residue. This vulnerability is greater when molars and premolars first come in, since their enamel has not yet hardened and their surface is less smooth.
Dental sealants: a benefit for oral health
A dental sealant is designed precisely to protect vulnerable premolars and molars against the bacteria that cause cavities. The sealant is a polymer applied to the grooved surfaces of the teeth that acts as a protective barrier: food and bacteria can no longer lodge in the grooves. It is an extra way to prevent tooth decay, often recommended for children and teenagers whose young teeth are more vulnerable to infection.
A simple, painless procedure
Sealants are applied without anesthesia in a single appointment. The treatment is simple, safe and painless. It takes a few steps:
- The dentist first examines the teeth to establish their condition and determine whether the treatment is possible and appropriate.
- The teeth being treated are cleaned thoroughly so that no residue or bacteria are sealed in under the sealant.
- A gel that helps the polymer adhere is applied, then the teeth are rinsed and dried well.
- The sealants are placed on the molars and premolars, then hardened with a curing light.
Dental sealants: a few details
This preventive treatment is mainly for young patients whose teeth are more vulnerable. However, sealants can also be useful for people who are prone to cavities or whose hygiene habits put them at risk. For the treatment to be truly effective, it is important to maintain good hygiene and a low-sugar diet. Finally, note that this is a purely preventive treatment: a sealant cannot be used to repair a cavity. We will therefore check the condition of the teeth before the treatment.
