An inlay is
similar to a filling and lies inside the
cusp tips of the tooth. They are custom-made
to fit the prepared cavity and are then
cemented into place. An onlay is a more
extensive reconstruction that covers one or
more cusps of a tooth. Onlays are indicated
in situations where a substantial
reconstruction is required. However, more of
the tooth structure can be conserved
compared to the placement of a crown.
To repair damage to the tooth’s biting
surface, rather than using a simple filling,
or a crown, a dentist will often use an
inlay, or an onlay. Inlays and onlays can be
made from porcelain, gold, or composite
resin, although porcelain is now becoming
the material of choice because of its
strength and potential to match the natural
color of your tooth.

To repair
damage involving over of the tooth’s biting
surface, rather than using a simple filling,
or a crown, a dentist will often use a
porcelain inlay or onlay.
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, now, porcelain is
becoming the material of choice because of
its strength and potential to match the
natural color of your tooth.
Inlays and onlays are applied in two dental
visits. At the first visit, your old
filling, or decay, is removed, and the tooth
is prepared for the inlay / onlay. Our
dental specialist will then make an
impression of the tooth, and send this
impression to our dental technician.
This impression will be used by our
technician to construct, a porcelain inlay /
onlay that will fit exactly into your
tooth. At this time our dental specialist
will place a temporary sealant on your tooth
and schedule a second appointment
At the second visit, your temporary sealant
is removed. Our dentist will then ensure
that the inlay / onlay fits properly in the
tooth and does not interfere with your
bite. Once correctly fit, the inlay / onlay
is bonded into the tooth with a strong
bonding resin, and polished smooth.
Typically fillings can reduce the strength
of the tooth by up to 50%. Inlays and
onlays, however, because they are bonded
directly into the tooth with special resins,
can actually increase the strength of the
tooth by up to 75%; as a result, they can
last from 10-30 years, and in some cases,
provide a good alternative to a crown.
