He couldn't help me with my tmj issues. Cost a lot of money and service was just not good enough. Changed to a dentist who was more willing to spend time on it and really look into my issue. My new dentist I can text at any time if I have a problem but john is very hard to get hold of and often the only way I could get hold of him was going to see him and spending another 120 quid. He also made some obvious errors like instructing me to wear a splint out of the box (they should always be adjusted to your bite). No doubt he's good at some things but if tmj is your issue find someone who's more creative, knowledgable and who cares more.
