Inlays and Onlays
Inlays and onlays are restorations that are made in the
dental laboratory and require two visits to complete. These
are an upgrade from fillings and are used when regular fillings
are not adequate to restore the teeth to function. That means
when the side of a tooth is broken or the hole is too large
for just a filling an inlay or onlay is used.
The difference between inlays and onlays is that an inlay
usually fills a hole created by the dentist and restores one
or two sides of the tooth. An onlay is usually larger and restores
the sides of the tooth as well as part or all of the chewing
surface.
Inlays and onlays can be made of different materials including
gold, resin composite or porcelain. As with fillings there
is a big difference in longevity among these three materials
with gold of course being the longest lasting by far. Choice
of material and restoration is guided by size, location, function,
and esthetics.
