Porcelain onlays are popular because they resemble your natural tooth. They are made by a professional dental laboratory and is permanently bonded onto the tooth by your dentist.
Onlays can be utilized to conservatively repair teeth that have large defective fillings or have been damaged by decay or trauma. Onlays are partial crowns and cover the biting surface of the tooth but may not extend all the way to the gumline resulting in less tooth structure being removed during the preparation .
Reasons for onlay restorations:
What does getting an onlay involve?
An onlay procedure usually requires two appointments. Your first appointment will include taking several highly accurate impressions (molds) that will be used to create your custom onlay and a temporary restoration.
While the tooth is numb, the dentist will remove any decay and/or old filling materials. The space will then be thoroughly cleaned and carefully prepared, shaping the surface to properly fit an onlay restoration. A temporary filling will be applied to protect the tooth while your onlay is made by a dental laboratory.
At your second appointment, your new onlay will be carefully and precisely cemented into place. A few adjustments may be necessary to ensure a proper fit and that your bite is comfortable.
You will receive care instruction at the conclusion of your treatment. Good oral hygiene practices, a proper diet, and regular dental visits will aid in the life of your new onlay.
