A dental restoration or dental filling is a dental restorative material used to restore the function, integrity and morphology of missing tooth structure. The structural loss typically results from caries or external trauma. — Wikipedia
When treating a cavity, Dr. McPherson will remove the decayed portion of the tooth and fill it with another substance. The two most common substances to use for fillings are either composite or amalgam.
Amalgam fillings, also known as silver-colored fillings, are made from a combination of metals. This combination of metal gives the amalgam fillings it renowned strength and durability. These type of fillings usually last 10-15 years. This type of filling is typically used for back molars where they are less visible, but because of its strength in those areas where the most chewing occurs.
After you’ve had an amalgam filling, you may experience temporary periods of sensitivity to hot and cold. Amalgam filling do not harden right away, and it is advisable that you avoid chewing on that area for a few hours.
A composite filling, also known as a tooth-colored filling, provides great durability for small to medium cavities. Typically, the procedure removes less tooth structure than during an amalgam filling. They are also well suited for treating front or highly visible teeth because of their natural look.
Be sure to consult Dr. McPherson to understand which dental filling is right for you.
