This min­i­mal­ly inva­sive restora­tion is long last­ing and high­ly effec­tive. The inlay or onlay is designed specif­i­cal­ly for your tooth, so it will fit the hole left by decay or dam­age. This is the best way to ful­ly restore your bite and pro­tect your teeth.

If you have suffered extensive decay in a rear tooth (molars and premolars) you might need an inlay or an onlay to help restore the biting surface. Porcelcain restorations can be designed to perfectly fit your tooth and create a natural-looking and feeling restoration. 

The difference between and inlay and an onlay

The treatment process will be the same, whether you require an inlay or an onlay, but the aftercare could be slightly different. This is because the risks for damaging each type of restoration will be slightly different. An inlay will restore the inner part of your tooth, so it is most likely to fail if you eat sticky or chewy sweets that cause the inlay to come loose. An onlay covers the outer cusp of the tooth, so it would be more at risk of chipping, cracking or coming loose. We can give you comprehensive aftercare instructions to minimise the risk of this happening.

What hap­pens dur­ing treatment?

The treatment takes place over two visits. During the first visit, we address the damage to your tooth and measure the space to be filled. It's important to get the right dimensions for the inlay or onlay so it fully restores your bite.

During the second visit to our dental office, we will permanently fix the inlay or onlay in place using special dental cement. Once in place, we'll then check that your bite is not changed by the addition of the restoration. As you will be numbed for the treatment, you might not be aware of any issues with the placement until the anaesthetic wears off. If you get home and the inlay or onlay doesn't feel natural, simply call our team to arrange a follow-up.

Inlays and Onlays Vs Crowns

Not sure if you need a sim­ple restora­tion or a more exten­sive restora­tion? These are some of the main dif­fer­ences between these two pop­u­lar treatments.

Inlays and Onlays

An inlay or an onlay is designed to restore a bad­ly dam­aged or decay­ing tooth. When the decay hap­pens deep in the cusp, this can be removed with a drill and filled with com­pos­ite fill­ing material. 

How­ev­er, if the dam­age is exten­sive or extends beyond the cusp, this treat­ment requires a dif­fer­ent approach to help pre­serve the tooth and bite. An inlay will be used is the dam­age is con­tained to inside the tooth, while an onlay may be required if the dam­age extends beyond the cusp of the tooth.


When a tooth is very dam­aged and weak­ened by decay, a crown might be rec­om­mend­ed to help pro­tect the under­ly­ing struc­ture. This is com­mon­ly rec­om­mend­ed fol­low­ing root canal treatment.

With a crown restora­tion, more of the under­ly­ing tooth struc­ture is removed to make space for the crown. In den­tistry, we need to strike a bal­ance between main­tain­ing your nat­ur­al tooth struc­ture and pro­vid­ing a stur­dy restora­tion. When decid­ing between a crown and an inlay/​onlay we will always try to be as min­i­mal­ly inva­sive as possible.

Fre­quent­ly Asked Questions

It’s com­mon to have lots of ques­tions about your treat­ment. We’ve answered some of the most pop­u­lar ques­tions below.

Inlays and onlays are more expensive than fillings because they are created from ceramic materials in a lab, rather than applied directly to the teeth and shaped. They are required to help restore the shape of the cusp of the tooth in cases of more extensive damage.

The main disadvantage is the time commitment required to place the restoration. It takes two trips to the dentist to place this type of restoration, which is similar to the treatment time for a crown or bridge.

This type of dental restoration is small and strong, which makes it very long lasting. With the right care, and assuming the restoration doesn't come loose, it could last from 20-30 years before it needs to be replaced.
