Dental materials contracting and expanding


Preston Dental Saskatoon Dental Clinic Services

Think back to elementary school, when you learned how things expand and contract depending on their temperature. It’s the same when you put ice inside of your mouth. If you have any dental work — such as fillings — they will respond differently to the cold temperature than the tooth around them does.If your teeth and fillings contract and expand at different rates, it can cause the bond between them to break down. The filling becomes loose, leaky, or may even result in your tooth cracking the next time you bite down.
