Tooth fillings replace decayed or damaged tooth material in cases where the cavity or damage is relatively small. In addition to protecting the tooth from further decay and the resulting pain for the patient, fillings can reduce sensitivity by covering areas that have lost their protective enamel.
At Markham Street Dental, we offer these filling materials: composite (tooth-colored), gold, or amalgam.
Composite material is sometimes called “white” filling material because of the natural, tooth color of the resin, which is made in many different shades of white so the dentist can pick the right color for your teeth. Hard plastic that bonds to the tooth, composite fillings are quite durable are are used in front teeth and molars alike. At Markham Street Dental, we use a composite material that is particularly quick-curing. This cuts down on the time you spend in the chair. Unlike inlays and onlays that are crafted in an outside lab, composite fillings can be made on-site and completed in only one office visit.
Comparison of Composite and Metal fillings
– Both metal and composite fillings are durable.
– Composites require far less drilling and loss of healthy tooth structure than do metal fillings.
– Metal amalgams and gold expand and contract when exposed to heat and cold. This movement weakens the tooth wall and can cause fractures. It also allows bacteria to enter and cause decay.
– Where metal fillings only serve to fill up the holes, composite materials are applied with bonding techniques and thus become more nearly part of the teeth.
– Amalgam is a mixture of metals, including mercury, a toxic element. The amount of mercury that is released from amalgams and the long-term effects on health are subjects of current controversy.
– Composites are tooth-colored and therefore more natural-looking than metal fillings.
– Filling with composite material usually requires less drilling than with metal, so more of the tooth is left intact.
– Composites do not cause the sensitivity that is often associated with metal fillings.
– Some people are allergic to metal fillings, but not to composite fillings.
Chemical Caries Indicator
Our Dr. uses a chemical-type caries detector designed to show which tooth material is infected with bacteria and which is healthy. Before placing the filling material in a cleaned cavity, she uses this chemical to ensure that all of the decayed tissue has been removed, while preserving as much as possible of the underlying non-infected dentin.
As the years have passed, it is possible that some of your old fillings may have become worn, cracked, or chipped. Metal fillings in need of replacement can be removed and replaced with composite filling material, which is tooth-colored and durable. The dentist takes special precautions to minimize any toxic metals that might be inhaled or swallowed during the proceeding.
