Dentists have used metal fillings to repair teeth for over 100 years. Fillings are safe and low-cost, and they last a long time, which makes them an excellent choice for repairing cavities. Metal fillings contain a small amount of mercury, and there have been concerns that this mercury can be released into the body. However, medical studies show that the extremely small amount of mercury released by metal fillings poses no threat to your health.
If you are concerned about the safety of metal fillings, talk to your dentist. Alternative treatments such as composite fillings may be a solution for you..
