I went to the office to check my teeth the other day. The guy dentist told me I had a few cavities. He gave me a quote. The last day of treating my cavities, he told me that I had another cavity to be treated. He added one more treatment from the first quote. I thought one more treatment was not big deal so I let him do that. But that's how my nightmare started. After the treatment, the tooth started hurting. The dentist told me that the tooth would be sensitive for cold stuff for next 2,3 days. After 2 weeks, the tooth still have been hurting whenever I ate cold and hot stuff. So, I made an appointment and visited at the office. The first thing he told me was I had another cavity to fix. That made upset cause he didn't even asked me what made me come to the office. I explained to him the reason I came to the office. He checked the tooth and told me "" You need to take a nerve and put a crown. I said ""Oh my god"". He said ""No worry, you have the good insurance to cover surgery. The other doctor told me that the tooth was closed to the nerve. So, I believe his treatment went too far and reach the nerve.
