Does tooth crack cause swelling and pain

I have lower jaw pain under the right ear with swelling on jaw line for more than 2 months.Had sinus congestion and went to Dr.Dr said the jaw swelling could be from sinus infection and gave me antibiotics.Sinus cleared up and the jaw pain, ear pain and Swelling still there.Went to dentist and took x-rays.It was normal.He did bite test and I felt pain and sensitivity to bite on one spot on tooth#46. So, he said I might have a fracture or crack and told me to take CBCT scan.he couldn't see it on the scan and said it's unpredictable.Told me to try extraction as RCT will not be successful.Also told me to extract upper right WT.I removed WT 20 days back. Still have the same symptoms.So the OMFS said it could be TMJ pain.But my dentist said it's a crack or TMJ. He said I might grind and clench at night.How to know if it's from tooth crack?I have severe sore ear pain, pain under the ear, neck pain(side of the neck little swollen).It's throughout the day and night.is it from tooth crack?help.
