If there is anything to give you mixed feelings, it is the dentist’s chair. The first obstacle is overcome when it is your turn to enter the treatment room. Will it be painful, what will be discovered, will there be an injection, and how long will it be bored. With my experience over the years, and I am a golden oldie of 73 years, there will never be a painless treatment. I feel sorry for dentists. No-one enjoys paying them a visit. And the grand finale: the bill for the treatment. You even have to pay for the pain.
