Amalgam Fillings - Pros / Cons
- Because of the metal content, amalgam fillings are strong and can withstand heavy biting pressure, and are therefore, used primarily for the back teeth.
- Amalgam filling material is relatively inexpensive.
- Most dental insurance companies cover amalgam fillings.
- Amalgam filling material contains mercury and other metals. While there have been no conclusive studies relating the mercury in amalgam to any dangers, mercury by itself is very toxic. Updated June 2008 - The FDA Admits Silver Dental Fillings May Not Be Safe.
- Some people experience a period of hot and cold sensitivity after having an amalgam filling.
- Amalgam fillings do not harden immediately. Therefore, it is not good to chew on that specific tooth for a couple of hours after the filling is placed.
- More tooth structure is lost because the dentist has to make a bigger preparation.
- Not all dentists do amalgam fillings anymore.
Composite Fillings - Pros/Cons
I prefer the composite fillings for the simple reasons that they look great, and the dentist can save a lot of my tooth structure, which means less drilling! With attributes to both amalgam and composite fillings, the pros and cons can help you decide what type of filling is best for you.
