I do love my straight teeth (braces) but I am a clincher, I do wear a mouthpiece at night, however I find myself clenching my jaws during the day as well. All teeth have major stress fractures I have many crowns already with 3 prior root canals, one was completed 1yr ago and it is decaying under crown. #4 on right side is cracked to the root in 3 pieces. Would it be cheaper to just pull all teeth and get dentures? I can not afford multiple implants; since certainly there will be more.
