Cavity Fillings Q&A

What Materials Are Used to Make Dental Fillings?

Dentists can use many different materials to create dental and cavity fillings. Silver amalgam has been used for years, but many dentists are turning away from it for multiple reasons. Porcelain, composite resin, ceramic-resin hybrids and glass ionomer resins are now being used because they are tooth colored and proven successful clinical studies. Composite resins and porcelain are extremely hard and can be used on the surface of the teeth as well as on the crowns. These composite fillings are bonded onto the tooth which also requires less drilling than amalgam/silver fillings need.

Are Cavity Fillings Permanent?

The quality of dental fillings and patient’s hygiene will determine their eventual lifespan. Cavity fillings are very technique sensitive that requires special attention to detail by the dentist. But well-placed fillings can also wear off, crack, fall out, or have recurrent cavities due to patient’s oral hygiene, diet, and habits. Make sure to follow instructions provided by your dentist after the procedures.

What Happens if a Dental Filling Falls Out?

When a filling falls out, you might have sensitivity on your tooth, but it is possible your tooth does not feel anything. If a filling is missing from its place, not only it is a nice space for bacteria and food particles to get trapped in, but also your dentin is exposed. When compared to enamel, dentin is much softer and more prone to cavities. It is essential that you seek your dentist to replace the missing filling as soon as possible. Composite resins, porcelain, and sealant materials are either white or clear. They can be used to replace the lost filling and leave no visible signs that a filling has been applied.
