Inlays and Onlays – the benefits of an advanced, conservative approach

Posted on 11.05.2013 by perfectsmile

Inlays and OnlaysIf you are in need of a dental restoration, you might want to consider this durable, advanced and tooth structure safeguarding method.

Inlays and Onlays are alternative restoration methods to fillings and dental crowns that are placed on teeth with moderate decay or mild fracturing. Also known as “indirect fillings”, these offer a durable, strong, natural-looking and well-fitting solution for restorations, being both aesthetic and functional.

Inlays are bonded within the centre of the tooth, whereas Onlays are used to cover the biting surface when the damage involves one or more cusps.


  • There are many benefits to this restorative treatment:
  • Colour match thanks to the materials used
  • Improved dental hygiene with a better sealing of teeth
  • Greater healthy tooth structure conservation
  • Finer fit without changing the tooth’s shape or size
  • Strength, stability and protection of the weakest areas

The application procedure

Similar to a tooth implant procedure, a previous preparation of the area before the treatment is required in the case of indirect fillings. The decayed part of the tooth is removed during a first visit when a moulded impression is also taken to send to the dental laboratory.

Along with a full guide to dental care for both your restored and natural teeth, your dentist will discuss with you which is the best material for your indirect filling (gold, porcelain or resin). For it to match the colour of your teeth, it is important that you consult your dentist if you are considering laser whitening in London.

A temporary piece will be placed in your tooth until your Inlay or Onlay is created. During the second visit, this temporary filling will be replaced by the actual piece; smoothly adjusted, bonded and polished to perfectly fit your tooth and bite.

Your dentist will minimise with anaesthetic any pain you might experience as a consequence of the removal of decayed tooth and the shaping of the Inlay or Onlay.

Choosing the right practice

Training for the application of Inlays and Onlays is limited, so there are a small number of professionals able to perform this procedure. Make sure your dental practice works closely to a dental laboratory or that your dentist is in touch with technicians to discuss the optimal treatment for your teeth.

As the cost of Inlays and Onlays depends on many factors (the materials used, the size of the piece, the difficulty of the work…) you should ask your dental provider under which category does your insurance places indirect fillings, as well as about their reimbursement rates.

A look into the future

Dental science strives to provide the most appealing solutions for you. Natural smiles with Invisalign are today possible for people with misalignment problems, as well as Inlays and Onlays are today’s preferred choice for natural-looking, durable and strong restoration treatments.
