Basic Guide to Inlays and Onlays

Inlays and onlays are used to repair damaged teeth and strengthen them. They are considered a conservative approach compared to traditional crowns and they tend to be quite durable and aesthetically pleasing. If you have teeth affected by damage such as fractures or decay, your dentist will consider inlays or onlays as a restorative dental treatment.

Inlays and onlays are an alternative to traditional dental fillings.

Fillings are moulded onto the tooth surface directly and this can be done during a single dental visit. However, inlays and onlays are fabricated in a dental laboratory. You will need to visit The Dental Practice Burwood again to have the inlays or onlays bonded to your teeth. This ensures a more precise fit which improve the function of your teeth and aesthetics. An inlay is a restoration that is within the cusps of the tooth or the chewing surface. They can repair damage that is limited to the centre of the tooth. This is generally for damage that doesn’t extend over the cusps. Moderate cavities can be treated like this. Or if you have tooth decay where there is no damage to the biting edges or cusps of the tooth, inlays can be used. An onlay tends to be a larger restoration. This will cover one or more cusps. It can also cover the entire biting surface of the tooth. These tend to be more extensive and can repair larger areas of damage. If damage is extending beyond the centre of the tooth, onlays will be used. They will provide greater coverage. Weakened tooth structures can be supported sufficiently with an onlay.

The advantage of inlays and onlay is that they are a conservative treatment.

They can preserve the natural tooth structure compared to traditional crowns. They will adhere to the existing tooth structure. It is only the damaged portion of the tooth that will be replaced by the inlay or the onlay so it can contribute to long term integrity of the tooth. These are also highly durable as they are made from materials such as composite resin, gold and porcelain. These materials are known to be stronger than the natural tooth enamel which means there is more resistance to staining, fractures and wear. You will be able to enjoy lasting stability with inlays and onlays. 

The inlays and onlays will be customised

So that they match the shape, colour and contours of your natural teeth and this will ensure seamless integration with your unique smile. Composite resin or porcelain are tooth coloured materials and these will blend in with your surrounding teeth so that the overall appearance of your tooth can be improved. The materials used are biocompatible and therefore well tolerated by oral tissues. This will reduce the risk of allergic reactions. If you have sensitivity to metal, this can be a good option. Porcelain inlays and onlays can mimic the natural appearance of your teeth and they are also stain resistant. Composite resin is very versatile and are suitable for both back and front teeth.
