Sealing your teeth. Steps and implications


Sealing teeth. Steps and implications

Once erupted into the oral cavity, teeth are exposed to local factors, including local micro-organisms that are responsible for the development of caries.

Especially with newly erupted permanent teeth, their relief is pronounced, so that sanitization is difficult, the toothbrush does not reach all the grooves and fissures, with the possibility of food debris remaining, especially on the lateral teeth, on occlusal surfaces.

Once food remains in the aforementioned areas, the fermentation process begins, with bacteria breaking down into acids that will trigger demineralization of enamel surfaces.

In the early stages of tooth decay, the affected surface becomes whiter, due to the demineralization process generated by the acids.

At this stage, treatment consists in mineralizing the affected surfaces.

When the caries progresses to produce cavities or to alter the surface of hard tissues, which become soft and infected, the treatment required is to remove all the altered tissue and fill the remaining cavity with physiognomic filling material.

If the destruction is significant and the tooth cannot be restored by filling, prosthodontic work should be carried out in collaboration with the dental laboratory.

Sealing is a treatment carried out in dental surgeries that involves cleaning the occlusal surfaces of the lateral teeth and applying a fluid material to soften the relief of the relief, with the aim of preventing caries.

It is important to know that sealants cannot be placed on decayed teeth or teeth that already have fillings or other types of work. Sealants can also be used on adults, but the teeth must be intact without any other interventions. Sealing is best carried out during the first year after the tooth erupts on the arch, as early as possible, as this considerably reduces the risk of carious processes developing.

Sealings are a simple, accessible, inexpensive and quick solution to prevent caries.

The steps for dental sealings are:

Initial consultation – the teeth are carefully inspected and assessed as to which teeth can undergo sealant treatment. Teeth that show the onset of carious processes or any other coronal destruction cannot undergo sealing, as there is a risk of decay developing under the applied filling material.

Teeth to be sealed shall be brushed with an abrasive toothpaste to prepare the surface for the application of the flowable material.

The surfaces will be conditioned with orthophosphoric acid to create conditions for retention of the sealant.

The next step is to apply the fluid sealing material to the deep areas of the occlusal surfaces, extend it into the grooves and fissures and light-cure with the UV lamp.

The method is a non-invasive one and their lifespan largely depends on the patient’s eating habits. Sealings are generally performed on molars and premolars, which, due to their occlusal surfaces, are prone to caries.

Following sealing, hygiene must be maintained with thorough brushing of all dental surfaces at least twice a day, without neglecting secondary methods of hygiene, dental floss, mouth irrigator, tongue brushing.
