[|Human|] I went SCUBA diving with a rented regulator (the piece you put in your mouth ) on the 25th. That night I realized my lower left tooth was hurting, much akin to wisdom tooth growth. I woke up yesterday with white and clear bumps on my outer gum that resemble the blisters which show up on skin because of fever blisters. I had to use the same regulator yesterday for my certification and this morning my gum has several small, shallow holes where the blisters burst or were rubbed away by the rubber. It is not swollen but it is tender when pressure is exerted. My teeth do not hurt, but under my chin behind the jaw bone is also tender. There is no swelling to speak of. The dive shop puts rented gear in a tank of Mean Green to disinfect everything before renting it out. I called to ask if they had heard of this situation occurring before and no one seems to know anything about this. Thanks for your help!
[|AI|]  Hi, Sometimes when there is already bacteria in the teeth and the nerve of the tooth is also irritated then going under pressure like scuba diving or airplane/flight, can lead to pain in that particular tooth. I would recommend you to visit your dentist for the same. The dentist may take a X-ray to determine if there is a cavity or an old filling that needs to be changed. You have maybe given a dosage of antibiotics for the same which will also help with the pain under your chin. The infection in the tooth may be the cause for lymphadenitis i.e.: infection of lymph nodes which you are feeling behind the jaw bone, under the chin resulting in tenderness. As for the ulcers, rubber regulators can abrade the mucosa and result in ulcers. They will go on their own once you use a Betadine mouthwash (not an alcohol based one as it will cause irritation) along with warm saline gargles. Also, you should include lots of green leafy vegetables to increase your vitamin intake and body resistance. Regards
