The Craze Over Craze Lines

The Craze Over Craze Lines

Posted December 11, 2014 by Wager-Evans Dental

craze lines Any number of things can go wrong with your teeth. Some of the usual things that go wrong are cavities, or tooth discoloration. Sometimes you may chip or crack a tooth. You may never have heard of craze lines but they look like tiny cracks in your teeth and can make you think your tooth is cracked. In today’s blog we discuss the craze over craze lines.

What Are They?

Your tooth enamel is one of the hardest substances in your body. Even so, it can wear, crack, and stain. Sometimes tiny, vertical cracks develop in the enamel of your front teeth. They can occur naturally from years of tooth wear, or due to trauma. They are painless because they do not extend into the dentin or pulp of the tooth, but they can be embarrassing because they become discolored.


Stress on the tooth is the major cause of craze lines. Tooth stress can be caused by:

  • Nail biting
  • Bruxism (grinding and clenching your teeth)
  • Using your teeth as a tool on hard objects, i.e. soda can tops
  • Tooth trauma
  • Tongue rings
  • Temperature changes (eating something cold after drinking something hot and vice versa)
  • Natural wear


Although some dentists worry that the cracks in your enamel provide more opportunity for decay, there is actually no need for craze lines to be treated. It is rare that further breakdown occurs due to craze lines. However, you can treat them by whitening your teeth, having the tiny cracks filled with a dental bonding material, or covering your teeth with veneers.
