VENEERS
Dental composite is a mix of plastics. Unlike porcelain veneers,
composite veneers are not sent to a lab for processing. Instead,
the composite is applied, in layers, directly on the tooth.
Because of the physical limitations of the material, composite
veneers are not always as durable or as lifelike as porcelain
veneers.
FILLINGS
When a cavity is removed from a tooth, the tooth must be
filled with something. There are several options available.
While it is most convenient to have a tooth filled at one
appointment, we are limited by the restorative materials available
that can be placed as a soft, malleable material which will
harden in a short period of time. There are currently only
two types of material that can be placed at the same appointment
in which the cavity is removed. One is composite bonding,
which can also be used for veneers and the other is dental
amalgam. Porcelain, gold and a variety of other materials
require two appointments. These materials require extreme
heat to make them melt and fit the tooth, so the restoration
must be made on a model of the tooth, not an actual tooth.
Incidentally, they are superior to composite and amalgam.
Composite bonding is the aesthetic and mercury free alternative
to amalgam fillings. Like the traditional silver fillings,
the composite fillings can be placed in one office visit,
opposed to a lab fabricated restoration. Unlike silver fillings,
composite materials do not have the fillings are not as strong
as their predecessors. Until there is a stronger composite
material, or the like, patients seeking mercury free restorations
will have to opt for more costly, albeit superior, restorations.
OTHER DENTAL MATERIALS
DENTAL AMALGAM
Amalgam is a mixture of several metals, including nickel,
silver and mercury. Mercury is what enables the material to
be malleable, so the dentist can place it in the prepared
tooth. The material then hardens and becomes locked into the
tooth. In addition to containing mercury, dental amalgam can
cause teeth to fracture. For these reasons, amalgam is less
commonly used.
GOLD
Gold is an excellent option for inlays, onlays or crowns
on back teeth.
Since the gold restoration is made in a laboratory, it can
be made to support a tooth and help prevent it from fracturing.
You may also use it on front teeth, if that is your thing.
It is the strongest of all the dental materials and is the
kindest to the opposing teeth. Due to its strength, less tooth
structure needs to be removed. Some people also feel gold
is a beneficial element for the body.
PORCELAIN
Porcelain is the strongest tooth colored material available.
It is excellent for inlays, onlays or crowns. You may use
it on the back or front teeth.
Since the porcelain restoration is made in a laboratory, it
can be made to support a tooth and help prevent it from fracturing.
Since porcelain is fragile, it can sometimes fracture. It
is also harder than natural tooth structure, which means it
will wear the enamel on the teeth opposing the porcelain restoration.
It also requires more thickness, for strength, than gold,
which means more tooth structure must be removed. It is generally
recommended that patients who receive porcelain restorations
also have a dental mouthguard.
