Minimal Treatment with Early Detection

Once adults lose their teeth, they never return to their original state. They are dissolved by acid produced by bacteria ​in the mouth, and tooth structure removed by cavity treatment will not regenerate. For this reason, early detection ​and treatment of tooth decay are of utmost importance.

The sooner cavities are detected, the less tooth structure needs to be cut. We particularly focus on conservative ​treatment with minimal cutting. We strive to preserve as much of the patient's natural teeth as possible and minimize ​damage.

Caries treatment by stage

The treatment of decayed teeth depends on the stage of progression.

Treatment for C0 (Signs of tooth decay)

C0 is an early stage of tooth decay that does not involve holes in the tooth surface. The only characteristic of this ​stage is the development of "white stains," described as white spots or cloudiness. There is no need to drill the teeth, ​and fluoride is applied to promote remineralization. You will be advised on how to brush in order to improve your ​hygiene.

Treatment for C1 (Mild caries)

C1 is a cavity in the enamel. It is a relatively shallow hole on the tooth surface that does not cause pain at this stage, ​but in some cases, cold objects may sting. Treatment is completed by drilling away the bacterial-infested tooth ​structure and filling it with a composite resin.

Treatment for C2 (Moderate caries)

C2 is a dentin cavity. The holes in the tooth surface tend to be relatively deep and large. Cold and sweet foods can ​induce a "toothache." After the lesion is shaved, treatment is completed with the fabrication and application of a filling ​or cover.

Treatment for C3 (Severe tooth decay)

C3 is a cavity that has reached the pulp of the tooth. The nerve of the tooth has been affected, causing severe pain. ​The pain can be induced by hot, cold, and sweet foods. A spontaneous pain called "zing zing" may occur even at rest. ​The treatment is completed by removing the nerve of the tooth, performing a root canal, and fabricating and fitting a ​covering.

Treatment for C4 (The most severely decayed tooth)

C4 is the terminal stage of tooth decay. The crown, which is the head of the tooth, collapses, and only the root of the ​tooth remains. Because the nerve is dead, you won't feel any pain. In most cases, tooth extraction is indicated when it ​has progressed to this point. Once the tooth has been extracted, the missing tooth is replaced with a prosthetic such ​as a bridge, denture, or implant.
