Inlays and Onlays

Inlays & Onlays

Teeth that are damaged or decayed will need to be restored. Your ability to chew properly will be compromised if the problem is not addressed. In some cases, a filling can protect against further decay, but this option may not provide the necessary protection your case needs. It is also possible the tooth is still relatively healthy, which means a full dental crown is not required. Onlays and inlays bridge the gap between a small filling and the need to cover the tooth entirely with a crown, and will stop decay before it develops into something more serious.

At Smile Chic, we provide patients a number of options to restore teeth that look natural whilst providing strength and stability. Inlays and onlays, also known as partial dental crowns, are usually made from a strong ceramic material. The result is an almost invisible restoration that can last for many years.

Dental Inlays & Onlays Treatment

When it comes to dentistry, our experts work hard to maintain and keep your teeth as healthy as possible for as long as possible. The longer you can keep your natural teeth, the better it is for your overall oral health. Inlays and onlays are a method of preserving teeth which have been attacked by decay. While crowns are an option for damaged teeth, they often require your dentist to file down or remove a little of your existing tooth, in order for the sleeve to fit nicely over the top and stay in line with your existing teeth. Onlays and inlays fit onto your teeth in a way that maintains all or most of your current tooth structure.

Larger cavities are best treated with inlays and onlays, as fillings simply won’t manage the damage. Inlays are very similar to fillings in that they close up a gap. An inlay sits inside your tooth, while an onlay is fitted to the outside of it and is usually used to build up any area of tooth damage or if your tooth has fractured. It is often the back teeth that require this kind of attention, as the surfaces of the ‘chewing’ teeth are particularly vulnerable to developing cavities.

An inlay fits within the chewing surface.
An onlay covers one or more of the edges.


Porcelain fillings are referred to as inlays or onlays, and are custom-made and then fitted to your teeth. They boast a similar durability to that of gold fillings, but look more more natural

Gold or amalgam

It is possible to get gold and amalgam inlays and onlays, however composite resin and porcelain choices make for a solution that is hardly noticeable

Composite resin

Composite resin is a kind of plastic that will match your natural tooth colour, making it less visible. The resin mixture can be poured straight into the cavity, making it a relatively quick treatment and little less durable than silver

Why Consider Dental Inlays & Onlays

How long does an Inlay or Onlay take to fit?

Treatments will take two appointments as the carefully moulded part to replace your tooth needs to be crafted in a dental laboratory. On your first visit, your dentist will take a mould of the tooth, which will be used to create the inlay or onlay. Your finished inlay or onlay will then be carefully fitted during your second appointment.

What are the Advantages of Inlays or Onlays?

  • Non-allergic
  • Stable, long-lasting and abrasion-resistant solution
  • Colour and shape perfectly matches own teeth
  • No colour change in the long-run, only with own teeth material parallelly
  • Even seriously damaged teeth can be saved using onlays

What is the difference between inlay and onlay?

The primary distinction between an onlay and an inlay is that an onlay will cover a cusp of the tooth, whereas an inlay only fills the area between the cusps.

Can an onlay fall off?

Unlike fillings that can discolor, shrink and fall out over time, inlays and onlays are permanently cemented onto the tooth where restoration is needed. You will also have the inlay or onlay matched perfectly to your existing teeth, creating a seamless and gorgeous smile that you can feel confident showing off.
