Porcelain Inlays and Onlays – What Are They?
Your teeth sustain a lot of pressure every time you bite, chew, or grind your teeth. Over time, tooth structure can weaken, and cracks form. These cracks will grow and get deeper if you leave them untreated, causing tooth sensitivity and increasing your risk of tooth fracture. Dental decay also weakens tooth structures.
In the early stages of breakdown, you have three options:
- Dental fillings
- Porcelain onlays
- Porcelain inlays
A porcelain onlay is a restoration that covers the biting surface of a back tooth. It can encompass a bit of the sides, too, but it basically sits on top of the tooth.
An onlay is recommended if you have a superficial crack in your tooth. You do not need a full crown yet because the crack is not that deep. However, your Downey cosmetic dentist will want to support the crack so that it does not progress. An onlay is the ideal option.
A porcelain inlay is a filling made of porcelain.
Your dentist will remove the decay from your tooth. Then, instead of placing a composite resin filling, they will use a CAD/CAM machine to fabricate a custom porcelain filling. The inlay is then permanently bonded/cemented into the tooth.
