What To Avoid If You Have Crowns

Crowns have no nerves in them, and thus cannot hurt, but if they are attached to the stump of a tooth (as they usually are), there are several things that can trigger a pain reaction. Crowns can break and become pointy and quite sharp as well, and can cut your mouth, gums, lips, cheeks or tongue. Breaking a crown is not easy, but it is far from impossible, and even new crowns can break if they are not treated properly. Here are a few habits and foods to avoid to make sure your crowns keep well for the longest possible amount of time.

Cracking crowns

Before crowns break, they usually crack. This crack can be completely invisible until it is already a bothersome problem that is potentially dangerous. Wider cracks can cut your tongue open, and you may not know it is there until something gets caught in it or gets lacerated. The most common cause of this is taking hot and cold things together, near each other.

Temperature change 

When you suddenly go into an airconditioned room from the midday summer heat and have a cup of ice cold drinks, or possibly an ice cube, you crack the enamel on your teeth. Your crowns are sturdier, but no different, really. They too will crack from sudden temperature changes. Not very noticeably, usually just microfissures happen at first, but these hairline fractures are enough to start the widening of the crack, until it gets big enough so that the jutting end of the crown can cut you. 


Bruxism is the condition when you grind your teeth involuntarily. There are varying degrees of bruxism, some people do it all the time, some only in their sleep, some do it just a little, some wear their teeth clean off with constantly gnashing and grinding. This condition causes the degradation of teeth, but can also cause teeth to be smashed into pieces by the crown, since the porcelain is harder than the tooth material. Bruxism also ruins the crown, and can cause problems with other teeth and gums. There is no way to treat people who are bruxing constantly, but we do know that bruxism affects you the most when you are unconscious, so wearing a night guard over your teeth will help protect your crowns. 

Bad habits

Smoking, drinking alcohol and taking drugs all make you more likely to grind your teeth, and are also all bad for your crowns. If you are addicted to substances, make sure that you keep your crowns and teeth clean and healthy, and try not to grind them. You will remain at risk until you seek help though, and a dentist will not be able to help you overcome, but teeth can be a great motivation to help quit.
