Can the fit of upper molar crowns be the cause of biting one's tongue or lip when chewing?

Question

For quite a while I have been sometimes biting my tongue and/or lip/cheek on the left side when I eat. Never on the right. I have 3 molar crowns on the left side & they appear to me to be shorter than what my original teeth were. Can upper molar caps that are changed in size of the original teeth be the cause of this? I didn't occur to me until I had one of the 3 molars pulled & a temporary crown put on. I then started biting my cheek so it made me wonder. Sorry no pics of old crowns

Hi:Cheek and tongue biting can definitely be as a result of new crowns if the size of the crown is a bit too large.  Fortunately you can have your dentist adjust the crowns so that problem goes away.  Please go back to your dentist and voice your concern.Best,Dr. Maddahi

Hello,
The most likely reason for this is an uneven relation on the way the upper and lower crowns are biting (bad occlusion)... the back teeth have cusps that need to be correctly related to their counterparts [top or bottom], if not, it can cause tissue [lips, cheek] biting. Hope this helps.
