“Should I worry about lines on my teeth?”

Lines may be cracked or weak areas on your tooth surface. You will need to get them checked by your dentist for sure.

Yes.

Your best answer will come from a dentist after an examination. Similar horizontal lines on several teeth could be the result of some activity when the teeth were being formed under the gum. An example would be a high fever affecting the growth of the teeth. Vertical lines could be crazing as a result of trauma. This could be something like eating hot soup followed by ice water. It could be something else. See your dentist for the best answer.
Thank you for your question.

Hello,

Are these lines something that you noticed in a certain light, and do they run top to bottom? If so, it sounds like they could be what we refer to craze lines. If they are craze lines, there is nothing to worry about. They are micro fractures in the enamel of the teeth and they are very common. Most of the time, people have them, they don't know because you can not see them. They start to become visible when the light hits them the right way, or if they pick up some staining. If they do pick up staining, you can do some teeth whitening to lighten them up again.
Hope this helps.

My best to you!

Hello, those are most likely stress lines from grinding or clenching. I would advise you to go to a dentist for an evaluation and possibly a night/day guard. Thank you for your question.
