New dental crowns causing TMJ flare-ups - Is this normal?

I am 30 yr old. I have been suffering from TMJD since 1 year. The symptoms started coming up after a dental crown placement on the left most molar in the lower jaw. The TMJD symptoms are also on the left side. Symptoms include pain in temples, around ear and neck, dizziness and tinnitus. 2 times I have had my crown fall off. Withiut the crowns I feel 70-80% better. But everytime the doctor has put a new crown, all my TMJ symptoms flare up and dont go away.
