Root Canals

Dizziness after root canals



Hi- 1 1/2 weeks ago my dentist began a root canal on my back upper left molar b/c I was in a lot of pain. Progress has been slowed because it was infected and I had to start antibiotics. My third visit was 3 days ago; the procedure is still unfinished. Thursday morning I woke up and felt extremely dizzy and I had to lay back down in bed. I ended up back in the office that afternoon to get a 2nd root canal begun on my lower left molar due to sudden pain there that began after my third visit for the 1st tooth.

The problem is that now--instead of having agonizing toothaches--I can`t lay, sit, stand, or walk without varying degrees of dizziness,instability, and incoordination. I can`t do anything without feeling very unsafe. I never have been dizzy like this before, so I feel like this all must be connected. Any insight you could give me would help me a lot. Thank you.


It would be very unlikely that your dizziness would be related to a root canal procedure. However, one can have dizziness from medications or medication interactions if you were prescribed certain types of medications.

I would seek care from your physician now if this dizziness is as debilitating as described to determine the cause and to treat your problem.
