Dentists fool themselves into thinking that ONLY the fillings that they remove have decay underneath.
This is incorrect…ALL of them have tooth decay under the filling.
And if you look very closely at the bottom tooth, you will see a crack in the natural tooth. How does this happen? All metals expand when heated by hot coffee, hot tea or a hot baked potato. Teeth are made of glass and do not want to expand at the same rate as the mercury filling. The result is that the natural tooth develops cracks which cause the tooth to break even when we are only eating a soft egg or soft pasta.
Think about this and ask your dentist to be PROACTIVE and replace all your old mercury fillings. It is a lot cheaper to replace old fillings than to have a mouthful of crowns or porcelain ONLAYS.
