Can anyone recommend a really excellent dentist? I have spent a fortune at Glow and keep emerging with my teeth feeling worse! Extreme sensitivity has lead to the dentist there making a mouth guard, replacing a filling, covering exposed dentin (same tooth) and drilling out a fissure crack in a neighbouring tooth. Rather than improving, the sensitivity is now chronic and severe. The dentist is now suggesting root canal... I feel I need someone else to take a look at the area. Any suggestions/advice? Thanks.
