Almost done with a root canal treatment. just need filling and crown. but bite is off and tooth feels like it has moved/shifted. is this normal?

Root canal: Are you having any pain or swelling? Talk to the dentist doing the root canal. It maybe something as simple as a temporary filling that is too high and needs a simple adjustment, or it could be an infection. See the dentist.

It is temporary: Your tooth will be properly restored with final restoration It is extremely important in ensuring long-term success. Take care.
