Why are my teeth sensitive to cold?
If you have excessive wear on your teeth and have crowns in your mouth you may need adjustment of your crowns periodically. Porcelain on crowns wears very little. Enamel on natural teeth will wear much faster than the crowns. If you have significant wear on natural teeth, it's possible your crowned teeth may be hitting heavy when you bite. One of the first symptoms of this is the crowned teeth being cold sensitive. The good news is it's an easy fix requiring only a bite adjustment by the dentist. This usually takes a matter of seconds and you don't have to lean your head to one side to drink your ice-cold Coke anymore.
