I was having a lot of pain from (as I found out) was a wisdom tooth, being a bit of a wuss, I kept putting off doing anything about it until I couldn't stand it any longer, luckily due to a cancellation, I was able to be seen within a couple of days.
The dentist diagnosed the problem, and a few days later I had the offending tooth extracted, it was a totally painless experience, the lady made me feel completely at ease, very friendly atmosphere, I have just been back and saw the hygienist, a very nice lady who did a wonderful job giving my teeth a clean, which they certainly needed!
Obviously, I can only comment on my own experience, but I will definitely be going back for a check-up in 6 months.
