I had a tooth ache for a couple of days. I believed I had a cracked tooth. I went to the dentist he examined it and he took an xray and told me I needed a root canal or tooth extraction. I went home and made an appointment with another dentist and seen him within 2 hours of the other dentist. He took an xray and examined it and told me that I needed a partial crown. Is this common in dentistry to come up with such different conclusions. I made a complanit with the State and they said there is nothing they can do. Should I always get a second opinion when having dental procedures done? Should I have reason to be upset over such different conclusions the dentists came to?
