What Are Dental Inlays and Onlays and Why Are They Recommended?

Has your dentist recommended that you get a dental inlay or perhaps a dental onlay? And are you wondering what the heck he is talking about? If you have had cavities or other damage to your teeth in the past, you may be more familiar with dental fillings or crowns – but sometimes inlays or onlays may be recommended instead.

What exactly are inlays and onlays?

Dental inlays and onlays are a thin covering usually made from porcelain or resin that are used in order to restore a tooth after there has been damage or decay. An inlay is used when the damaged area does not cover the cusp or biting surface of the tooth and an onlay is used when there is damage to the cusp or biting surface.

Generally speaking, an inlay or onlay will be recommended by your dentist when there is too much damage for a filling to restore the tooth but not so much damage that a crown is required to restore the tooth.

Just like with a regular dental filling, the decayed area is drilled out and then the inlay or onlay is inserted. The process usually takes two dental visits to complete. During the first visit, your dentist will do any necessary drilling and remove the decay and then fit your tooth with a temporary inlay or onlay after which he will send impressions to the lab so your permanent inlay or onlay can be made. These are made not only to be an exact fit of the area being filled, but they also match the colour of your teeth so they will be practically invisible. Once the permanent inlay or onlay is ready, your dentist will remove the temporary one and replace it with a much stronger permanent one.

What are the benefits of inlays and onlays?

Dental inlays and onlays are an effective way of restoring decayed and damaged teeth. Benefits include:

  • They look very natural – it is nearly impossible for others to tell you have had work done to your teeth.
  • They allow you to preserve more of the natural tooth than a crown would.
  • They are an ideal solution for filling tricky cavities between the teeth.
  • They are extremely strong and durable.
  • They resist staining.
