He worked not only once but twice on the same cavity I had which he'd first to remove an old filling that I had for many years--I wish he did not!! I was a whole lot better off with my old fillings.
Anyway, after the first filling my tooth never healed and I could not chew on it at all. So I went back again, he drilled out the last filling he did and re-filled it but, the second time was much more worse than the first. He made my pain worse than it ever been and I still cannot use my tooth, it is way too sensitive to use, can't even drink water through the side of the tooth, I have to tilt my head to other side to avoid the painful tooth.
The worst thing was he'd to give me the local anesthesia one too many times. I'm now so scared to go back to him to have him correct the wrong he'd done again, I'd rather stay in pain and use just one side of my teeth/jaws until I find another dentist, hopefully, a good one.
