One of the most adaptable restorative materials in dentistry is dental amalgam. It accounts for over 75% of all restorative materials used by dentists.
<h3>
What is amalgam?</h3>
Dental amalgam is a mixture of liquid mercury and metal alloys used to treat cavities caused by tooth decay in dentistry. [1] Mercury (50%) is typically found in low-copper amalgam, along with silver (22–32%), tin (14%), zinc (8%), and other trace metals.
Because of the constant expansion and contraction of amalgam fillings, they can sometimes shatter the tooth. Leakage is also less likely with composite fillings. A leaking filling indicates there is a small breach between the filling and your tooth, which allows dirt and saliva to enter and cause decay.
