The type of cavities that occur between the teeth are called interproximal cavities. Any cavity occurs due to a combination of factors, such as improper oral hygiene maintenance, frequent snacking, decreased immunity, etc. Due to this, the enamel gets worn away from the teeth, and the bacteria sticks to the tooth, eating it. This can eventually cause tooth decay or caries.
How is an interproximal cavity diagnosed?
It is very hard to identify an interproximal cavity on our own. You will only experience the symptoms caries reach the layer beneath the enamel, i.e., dentin. You may experience symptoms like sensitivity to hot and cold food or beverage, pain, discomfort, trouble chewing, etc. A dental expert can use radiography to identify this condition.
How is an interproximal cavity treated?
When a cavity between the teeth occurs, the dentist will recommend suitable treatment in order to stop the infection or decay from spreading any further. Broadly, the various types of treatment modalities are recalcification, filling, and root canal, followed by crown placement and extraction.
Recalcification or remineralisation can only be done if the cavity is caught very early, and a fluoride application is done to stop the progression. If the cavity extends more into the enamel, a dentist will do a restoration to bring its normal function and shape back. In restoration, the dentist removes the decayed part and fills with a suitable filling material as per the patient’s choice, such as composite, amalgam, gold, etc.
But, in cases where caries has reached the innermost layer of the tooth, i.e., pulp, there is a need for RCT or Root Canal Treatment to save the tooth. The procedure involves the removal of the pulp and the decayed area, after which the tooth is cleaned, disinfected, shaped, and finally filled. After this, the dentist places a crown over the tooth to cover the filling and support the tooth. They are made from a variety of materials, including ceramics, composite resin, metal alloys, porcelain, or a combination.
The last resort to treat it is an extraction, especially if the tooth is beyond restorable. The dentist can fill the space after the extraction with a bridge, a partial denture, or a dental implant later on.
