Grinding/Open Bite I have been wearing an NTI night guard for two years to prevent grinding.
I recently visited the dentist who noticed that I now have an open bite, can only make contact in my back teeth. I used to have a regular bite and could touch my front teeth together.
How could an open bite form so late in life (I'm 22)? Did the NTI play a part? My x-rays show that the change has been taking place gradually and before I started with the NTI. What are the possible solutions? ...Visitor from NY
The literature says that the NTI can cause open bites.
I have my patients sign an informed consent saying that they should discontinue using the NTI if there are changes in the bite. I have yet to see an open bite that is caused by the NTI.
If the teeth function during the day, any tooth movement that occurred at night should be corrected by normal use during the day (just like an orthodontic retainer will shift teeth back into the correct position at night).
If your x-rays show that you had an open bite before you used the NTI, I really doubt that this caused it. Nevertheless, I would discontinue use of the NTI and see an orthodontist about the open bite.
