Chomping on ice
JeniFoto/Shutterstock There are so many habits dentists wish you’d change when it comes to taking care of your teeth. But one of the biggies? Chewing ice which can chip away at fragile tooth enamel. “It can also crack teeth already weakened from restoration work,” says Harold Katz, DDS, who holds degrees in dentistry and bacteriology. Instead of chomping on ice cubes, ask for crushed ice if this is a habit you just can’t quit and know this: A cracked tooth may lead to a exposed tooth nerve that might even lead to a root canal. Be aware of these things that your dentist needs you to start doing differently.
