Two aspects have to be taken in account regarding the treatment of a cavity assessed: the degree of damage to the tooth and if the tooth is temporary or permanent.
Teenagers with immature permanent teeth, the treatment will be different compared to an adult permanent tooth with fully formed roots.

Types of treatments

The treatment of cavities affecting the enamel and dentin without affecting the pulp or vascular-nervous tissue of the tooth is a filling, which will be the same for both temporary and permanent teeth. In the case of incipient caries that partially affects the surface of the enamel, the patient will be asked to improve his or her oral hygiene and a regular clinical monitoring will be performed in the consultation room.


Children with a high risk for caries, fissure sealing should be considered as a method of caries prevention. When a cavity is already affecting the thickness of the enamel and progressing to the dentin, treatment will begin by removing the infected tissue. Once the diseased dentin is removed, the tooth is restored using composite resins or composites. One of the most positive aspects of composites compared to amalgam is their aesthetics and lack of toxicity.
Composites offer a wide range of white colors close to the natural color of each patient, and can even be unnoticeable. The adhesion of composites to the tooth by treating the surface of the healthy tooth with bonding agents has been another advantage over metal fillings.

Endodontic treatment

When there is a deeper damage to the tooth tissue, the decay coming into contact with the pulp. It manifests itself as pulpitis (nerve damage, toothache and inflammation of the pulp tissue), the treatment choosen in this case will be endodontics of the adult permanent tooth (killing the nerve).
Endodontic treatment consists to remove the vascular and nerve tissue of the dental pulpe, found in the pulp chamber (inside the tooth) as well as in the root canals of the tooth roots. Once this tissue is removed, it is replaced with a bacteriostatic material that prevents the recurrence of dental infection.

Other cavities treatments

In primary teeth, pulpitis treatment will be more conservative, using techniques such as direct and indirect capping, pulpotomy and pulpectomy. In permanent teeth with developing roots, conservative techniques such as direct capping are also used.
