A Molar with a Failed Onlay Filling Often Needs a Crown

Posted .

When tooth decay afflicts the biting surface of a molar, it often requires an inlay or onlay filling. Onlay fillings are typically larger and include elements of the side of the tooth as well as the occlusal biting surface. The passage of time and any inconsistencies in your oral hygiene routine can weaken the bond cementing an onlay filling to the surrounding healthy tooth enamel.

If bacteria invade the seam of the filling, it could cause a new area of decay to form or cause the onlay to fall out.

In a situation like this the dentists Christopher M. Granillo, DDS, LLC’s Tucson, Arizona clinic might advocate a total crown restoration. This method of treatment will replace the entire tooth enamel layer with a durable, alternative material.

Your dentist will start by examining the tooth and taking some X-rays to assess the extent of the problem. If they find additional concerns, they will present you with additional treatment considerations.

The dentist will then remove any remaining tooth enamel, leaving behind a post-shaped core of the tooth, called an abutment. This will serve as an eventual anchor for a crown.

An impression will then be made and sent off to a dental lab where the final crown will be created. In the interim, a temporary crown will be cemented in place to protect the abutment.

We will call you back in for a short second appointment when your crown is completed. Your dentist will remove the temporary crown and cement your new permanent crown in place over the abutment.

If you live in the Tucson, Arizona area and you have lost a molar filling, you should not delay in calling 520-298-5556 to have it treated at Christopher M. Granillo, DDS, LLC’s dental clinic.
