Inlays/Onlays

Inlays and Onlays are restorations that are used to rebuild a tooth that has lost a significant amount of its structure due to decay or trauma. Similar to dental fillings but rather than being directly placed into your tooth and then set, they are fabricated in our dental laboratory and then cemented into place. This is known as an ‘indirect procedure’. Inlays fit into the tooth whereas onlays sit on top of the remaining tooth structure.

Inlays and Onlays can be constructed using:

Porcelain
Gold
Composite

Your dentist will evaluate your tooth to see if it is suitable for an Inlay or Onlay and also decide which material is best.

The procedure

Two appointments will be necessary: the first to prepare the tooth surface and the second to fit the Onlay or Inlay.

The first appointment

A local anaesthetic is given to numb the tooth and the surrounding tissue.
Any decay that is present will be removed and the tooth surface will be prepared for the restoration.
An impression (mould) is taken of your teeth using special dental "putty". The putty is placed into an impression tray; they are both then inserted into your mouth and pushed onto your teeth in order to take an impression. Once the dental putty is set, the impression will be removed. An impression is also taken of the opposing teeth, so the technician can see how you bite together.
A temporary restoration will be placed on the prepared tooth to protect it whilst your Inlay or Onlay is being fabricated.
The impression is sent to our Dental Laboratory where our technicians will custom make your Inlay or Onlay. This can take up to two weeks.

The Fit Appointment

A local anaesthetic may be needed to numb the tooth and surrounding gum.
The temporary restoration will be removed and the tooth cleaned.
The dentist will then try in your new Inlay or Onlay, making sure the fit is perfect, your bite is comfortable and you are happy with the appearance. The Inlay or Onlay will then be permanently cemented in place.

Frequently Asked Questions

Should a Parent accompany a child into the treatment room?

We’ve been asked:

Should a parent accompany a child into the treatment room?

Dentists frequently prefer that parents do not accompany children into the treatment room since they want to gain the child’s attention and establish control of the situation.

However, for the first visit, it can be comforting for the child to have a parent come along for the process of getting settled into the chair. Some children do much better with a parent there for support, while others may become unruly because they know they can manipulate their parents. Some parents just can’t relinquish their child to another’s care and may interfere unnecessarily, or they may distract the child with bribes, reprimands and conversation.

Mary Anne does like having parents in the room. But, she does prefer to establish one-to-one relationship with the child (as in asking parents to observe only).

Could you stay out of your child’s line of vision and don’t talk.

If your preschooler finds it comforting to hold your hand the dentist may agree to let you do this after the first 10 minutes

There may be some occasions when if treatment is not completed/not attended we are obliged to report this to other child providers.
