When a tooth is damaged beyond the repair of a filling, dental onlays provide a great conservative option to give you the best chance of restoring your natural tooth’s structure.

Capping a tooth with a crown can lead to unnecessary loss of tooth structure. Dental onlays offered here at Hooper Tooth Conserving Dentistry and carried out by our exceptional professionals, provide a more conservative approach to repairing the natural strength of your tooth.

Onlays are a brilliant way to restore broken, decayed or damaged teeth for a handful of different reasons:

  • The restoration preserves as much of the tooth structure as possible
  • The onlay is made from composite resin materials, offing a natural and completely unnoticeable looking replacement
  • The materials are strong and long lasting
  • An onlay bonds to the natural tooth, giving the tooth strength rather than weakening it over time
  • They are a lot less expensive than a crown

Onlays in comparison to crowns cover only the portion of the tooth that needs replacing and are sometimes referred to as “partial crowns”.
