Terrible experience , explained my problem , took pictures and X-rays and failed to notice a 8mm deep crack in my back tooth . Subsequently I spent the whole weekend in emergency in the hospital as they tried to diagnose this mystery agonizing pain . Finally I went on Monday to another dentist who took the same pictures and X-rays that dr gill did and discovered the problem . I then had to lose my work week and now have to have my tooth extracted . I'm not happy at all . I emailed him and explained my dissatisfaction , but never heard a word back . That's why I'm here .
