How Inlays and Onlays Are Different

Inlays treat teeth with decay or damage on the top surface of the tooth, or to replace damaged or old fillings created from silver amalgam, considered a potential health risk.

Generally speaking, your inlay placement requires two dental visits. Once you receive your permanent inlay, however, you can carry on with your normal activities, despite some mild and brief tenderness.

Onlays treat decay that extends to one or more teeth, in a process very similar to that used for inlays. Your permanent onlay is placed on your tooth and bonded securely with high strength resin.

Benefits of Inlays and Onlays

Both inlays and onlays can be crafted from natural looking tooth-colored material for a more natural smile. Because the process does not require extensive removal of the tooth’s structure, more of your natural tooth can be conserved, helping you to avoid further reconstructive work in the future with crowns, implants or bridges. The high strength resin plays an important part as well, since bonding the material to your natural tooth adds strength and prevents bacteria from forming cavities on the tooth. When these benefits are combined, it means much less dental work in your future, which is a benefit we all can appreciate.

Additional Benefits

  • Inlays and onlays do not expand or contract with temperature changes from hot or cold foods. This can cause teeth to weaken or break and is a common occurrence with older-style metal fillings.
  • Inlays and onlays help to strengthen teeth up to 75 percent.
  • Inlays and onlays are very durable, lasting up to 30 years. Conventional fillings cannot make this claim.

Because of their strength, durability, and beauty, inlays and onlays are an increasingly popular solution for areas of large tooth decay.
