If teeth have been lost, then replacement options include
implants, fixed bridges or dentures. A bridge may be used to fill
a gap of up to four teeth if there are healthy natural teeth either
side of the gap. A fixed bridge is an appliance made of porcelain
to replace missing teeth in the most natural way possible. This
procedure usually takes 2 visits to complete and is similar to
having a crown placed. A bridge consists of a crown on either
side of the gap where the tooth has been extracted, known as abutments,
with another tooth fixed in between, called a pontic.
If a tooth is severely decayed, brittle or when a substantial
portion of the tooth structure has been lost, a full crown may
be required. A fractured tooth or old restorations with open leaky
margins and decay, may also need a crown. Crowns protect heavily
restored teeth and prevent further fracturing and are made from
either porcelain or gold. As with bridgework, usually only 2 visits
are required and a laboratory technician is involved in the process.

Implants are a highly predictable way of replacing missing
teeth – from a single tooth to a full arch –
and are designed to look like and function in a similar
way to natural teeth without compromising any of the remaining
teeth. Because these fixtures maintain bone, dental implants
greatly reduce the collapse of facial contour which follows
loss of teeth. In many cases, lost contour can be restored
in conjunction with this treatment. Implants can also be
used to improve retention, comfort and support of loose
fitting dentures.

To repair damage involving over ½ of the tooth’s
biting surface, rather than using a simple filling or a crown,
an alternative would be an inlay or onlay. Inlays and onlays can
be porcelain, gold or composite resin cast sections that are bonded
to the damaged area of the tooth. An inlay is similar to a filling
and lies inside the cusp tips of the tooth; an onlay is a more
extensive reconstruction that covers one or more cusps of a tooth.
Inlays and onlays are both traditionally made of gold, however,
porcelain is now becoming the material of choice because of its
strength and potential to match the natural colour of your tooth.
