Hello,
I can understand your concern. There are several reasons that can cause a
tooth fracture. First is having carious lesion that makes teeth weak by cavitation and may fracture them. However, as you regularly visit your
dentist twice a year, your dentist must have found them before fracture them and have informed you about their presence.
Secondly, it could be attrition. As we age, out teeth go through physiologic wear due to chewing, grinding and other normal functions. This may make teeth surfaces flat and may cause cusp or angle
fractures in teeth.
Lastly, it could be erosion due to constant acid attack. If you are frequent consumer of carbonated drinks or concentrated lemon juice, or suffer from diseases that can cause regurgitation of acid into mouth like
acid reflux disease or frequent
vomiting or bulimia/
anorexia nervosa (eating disorders), it can cause concavities in teeth like you are explaining and make them fracture. I assume this as a more possible reason for you as incisors are attacked first in such cases.
I would advise you to get treatment for the any acid refulx disorder if you have them and restrict on acidic food/drink consumption. In addition, you can go to the dentist and ask to make a bite guard for you that you can wear to protect teeth from constant wear.
I hope this information helps you. Thank you for choosing HealthcareMagic. Let me know if you have any follow up questions.
