I was one of his patients since I was 12 yrs old. All I can say about david birdwell and his staff are very outgoing people. They treated me with care. I had the full works with my teeth. It was only my two k9 teeth that were out of place. Then I had my jaw fixed with metel and rubber bands. Gosh all I can remember was when they took the first picture of me I could see how diffrent it was when I saw my finishing picture. There was no pain involved except, never watch a scary movie about a pshyco dentist! Lolz meanwhile, I was greeted evertime I showed up for my appointments. Everyones manners was so cheerful. The cost of everything that was done to me was expensive. It paid off when I seen results. All that I can remember was I took them off when I was 18. hathethem off then off for a good 7 yrs.
