When Might I Need an Inlay or Onlay?
Our tooth coloured composite resin fillings are perfect for restoring small to medium sized cavities in your teeth but if you have any larger areas of decay in your back teeth then composite resin may not be strong enough. This is when we’ll suggest you have a porcelain inlay or onlay as this material is much more hard wearing and will be easily able to withstand chewing. These porcelain restorations can replace structure and will restore strength to a more badly damaged tooth. Although a little more expensive than a composite resin filling, they will last substantially longer, they will not stain or discolour in any way and they look great.
What is the Difference Between an Inlay and an Onlay?
Tooth Savers will suggest an inlay if the decay in a tooth is limited to the central part of the chewing surface. An onlay is slightly larger as it can replace this central area plus one or more of the tooth cusps. The cusps of a back tooth are the raised points you can see on the edges closest to the cheeks and tongue.
What is the Procedure for an Inlay or Onlay?
Your tooth will be prepared in the same way for a filling. Afterwards we will take an impression of the prepared tooth that is used by our dental laboratory to fabricate your new porcelain inlay or onlay. This can take up to 2 weeks and in the meantime we will place a temporary filling to protect your tooth. On your next visit, your new restoration will be tried in and permanently cemented in place.
