1. Chewing ice
Unfortunately, there’s a ton of bad habits all dentists wish their patients would change, but the biggest one of all is probably chewing ice. This awful habit can lead to fragile tooth enamel. And that’s not all. According to Dr. Harold Katz, the California Breath Clinics founder, chewing ice can also crack teeth.
So, if it seems impossible to quit this bad-for-your-teeth habit, then ask for crushed ice instead of ice cubes. If you won’t, just keep in mind that a cracked tooth can eventually lead to an exposed tooth nerve, therefore to a root canal.
