If you have old metal fillings, it may be time to consider replacing them with a more natural-looking alternative. White dental fillings are able to blend seamlessly into your smile, allowing them to both protect and beautify the affected tooth. However, the appearance of metal fillings is not the only reason to consider having them replaced. In fact, it’s not even one of the most compelling.
Metal Fillings Damage Teeth
In order for a metal filling to be placed into a cavity, a larger hole must first be drilled. This allows the amalgam to be packed into the cavity where it can expand to completely fill the space.
Metal fillings do not bond to the surface of the tooth but instead rely on expansion to prevent bacteria from entering the cavity. Unfortunately, this expansion never really stops, nor does the contraction that occurs when temperatures change in the mouth. Over time, this can allow metal fillings to come loose and fall out or to break teeth from the inside.
As if breaking teeth alone wasn’t problem enough, some of the metals used in amalgams have been shown to be toxic – so toxic that it is recommended amalgams not be placed in pregnant women or children. Hayward family dentist Dr. Gary Fong believes this precaution should be extended to all of our patients.
Why White Fillings are Better
White fillings are nontoxic and safe for placement in men, women, and children alike. What’s more, tooth colored fillings are bonded to the surface of the teeth, allowing them to keep bacteria out and prevent further decay by fully sealing the cavity.
White fillings do not expand or contract as temperatures change in the mouth and they look exactly like natural tooth enamel – allowing them to enhance both the strength and appearance of the teeth they protect.
