Now that you have a cavity, what type of dental filling should you get? There are several choices of filling material that you should know about before you make your decision regarding what type of tooth filling your dentist should use on your decayed tooth. Knowing what’s available can help you make the best choice for your mouth.
Amalgam
Amalgam fillings are a mixture of primarily mercury, along with tin, copper, silver or zinc. Dentists have been using this type of filling for more than 150 years. It is a popular choice because it is long lasting, strong and inexpensive. The filling is silver in color and can become darker with time. It requires the removal of parts of your tooth which are still healthy for the filling to adhere properly.
Composite
Composite fillings are made with a tooth colored putty like material that is placed into the cavity while it’s soft, then hardened with bright blue “curing” light. It doesn’t require the removal of too much of the healthy tooth for the filling to adhere properly and is more natural looking. The cost is more than the amalgam and lasts over 5 years usually.
Gold
Gold fillings are the most expensive and longest lasting option. It takes more than one visit to fit a gold filling properly. They can withstand chewing force and are tarnish and corrosion resistant.
Porcelain
Porcelain or ceramic fillings are shaped to fit the cavity and then cemented to the tooth. They are very natural looking and last over 7 years. It can require more of the healthy tooth to be removed and a couple of office visits.
Choosing the right dental filling will depend on how much you can afford to pay, how big a cavity needs to be filled, and what your personal preference is. Call Friendly Dental for all your dental needs.
