One dentist always yelled at me for not doing a good job, I didn't want to put up with that.
One dentist relocated to an area that was not covenient for me.
One dentist suggested a major procedure that I was not comfortable with.
One dentist was not gentle, as a matter of fact, whatever he did was painful.

DENTIST VISIT by snowriderguy, on Flickr CC BY-NC-ND
Finally, after all these years I have a great dentist - as a matter of fact I have an appointment with him this week.
His office is located across the street from the ocean which is a short distance from my home, doesn't keep me waiting and has a very capable hygienist. Now, you know what happens when you get into the dentist's chair - you try to have a conversation with the hygienist inbetween "open wide" and "rinse." Somehow we manage to comunicate very nicely. She gets my mind off the procedure and before I know it, I'm done.
Once I leave the office, if the weather is good I take myself for a walk along the beach. I get to see mothers with their babies, people walking their dogs, runners, old people walking and some sitting on benches. Me, I walk a little and then pull up a bench.
Before I call it quits I go over to an ice cream stand, have myself a butter pecan ice cream cone, pull up another bench and enjoy the sunshine.
From there it's just a short walk to the library, I pick up some books and head home. I've had a great day and didn't even have to move the car from once spot to another!
How do you feel about going to the dentist?
