Have you noticed fine, vertical lines running through your teeth? These harmless yet sometimes concerning marks are called craze lines, and they're a common dental occurrence that affects many adults. While they might cause aesthetic concerns, understanding what these lines are and how they develop can help put your mind at ease about your dental health.
In this comprehensive guide, we'll explore everything you need to know about craze lines in teeth, including their causes, how to identify them, available treatments, and prevention strategies.
What Are Craze Lines?
Craze lines are microscopic cracks that appear in the enamel layer of teeth. Unlike serious tooth fractures, these superficial lines only affect the outer protective layer and typically don't compromise the tooth's structural integrity. They commonly appear as vertical lines running from the gum line to the biting edge of the tooth.
Common Causes of Craze Lines
Several factors can contribute to the development of craze lines in teeth:
- Temperature changes from hot and cold foods
- Natural aging process
- Biting pressure from normal chewing
- Teeth grinding (bruxism)
- Nail biting or chewing on hard objects
- Traumatic injury to the teeth
