Loose teeth HELP!

My husband just called me and said his wisdom tooth is moving right and left. He thinks it will fall out. He has had receding gums and a canine tooth (I think that's what their called) out of place it has come down. Looks longer then the other teeth. He always feels an itch in his gums after he eats. He has A LOT of stress with work. He has trouble making decisions. He always thinks of the others instead of himself. He always thinks he is the victim or slave for others. He has not had a cleaning at the dentist office for two years now. But he is very thorough when he cleans his teeth. He uses mouth wash, neem tooth paste, and rinses with sea salt. A couple of years ago his dentist wanted to pull another tooth because half the root of a tooth was missing, the dentist had no explanation. Please HELP HIM, I will be eagerly waiting for a response and a recommendation.
