Cpap and tooth pain

I have just started using a cpap machine almost two weeks ago. I am now experiencing pain in my upper and lower jaw/teeth on left side. Hot and cold causes severe pain. Sometimes the pain will cause my left ear and head ache. The more I move the more it hurts. My dentist checked my teeth and took a couple of x-rays. No cavity, problems with nerves, did not see any issues. He put pressure on the sinus area, both sides, inside of my mouth. I had pain when he applied the pressure and diagnosed me with sinusitis. Gave me an antibiotic and told me to use a nasal decongestant. So I have been taking the antibiotic for 3 days now and the decongestant for 2 days. Not much has changed. Only a little less pain. I am not convinced this is a sinus infection. When I look up the symptoms for it, it does not say anything about hot/cold sensitivities and it only says your teeth ache and you have pain in you upper teeth. The cold and hot causes me severe pain. Anybody else ever experience this and have any thoughts or ideas of something else it could be. I often wonder if the cpap machine has caused this, as it happened a few days after I started using it. I can see how the cpap machine could cause a sinus infection, but it is hard to believe it could cause these kind of symptoms. On a previous post I see someone else had basically the same issue, only on the right side. Just not a lot of detail there to help answer my question. Has anyone else ever experienced this? Have any thoughts or ideas of what else it could be? Thank you.

Hot/Cold sensitivities usually means nerve problems...possibly root canal.

Possibly you're grinding your teeth. You may be experiencing this now because you weren't in a deep enough sleep before for this to happen on this scale.

Early on, I had lower teeth pain, due to the mask, not the machine. It eventually went away, but I suspect the mask pressure caused it.

Possibly mask too tight, and or mouth becoming too dry, or bruxism.

I had a horrible toothache this summer and my daughter told me to take a Claritin D. It made it go away and so far hasn't come back.

Dental pain, followed by no trip to the dentist.
I would not advise that.

I found that after I used cpap for a while that I had started clenching my teeth. This caused painful sensitivity to hot and cold on one side of my mouth. I guess that was part of my endeavors to avoid mouth breathing at night, just clenching my teeth together and hoping for the best *smile*. When the sensitivity got bad, I also went to my dentist and got x-rayed, etc. She couldn't find anything wrong, so sent me on my way, no suggestions...she didn't even suggest that it might be from teeth clenching or grinding, so I have since switched dentists and am very happy with the new one. I figured it out all on my own *smile*, from what I read on the internet.

The way that I dealt with this was to consciously work on not allowing my teeth to clench or even touch during the day (they're not supposed to be pushed together), and doing what I could towards the same end at night. This jaw retraining has worked for me over the years, and that jaw/tooth pain and sensitivity is now long in my rear view mirror...not an issue for several years. If the conscious focus on keeping my teeth apart (like they're supposed to be, from what I've read) hadn't worked, I was ready to start using a night guard mouthpiece. One of those boil-and-bite things that you see around would have worked just as well, but I'm glad that I don't have to have more gear at night. Earplugs and a cpap mask are quite enough, thank you *smile*.

Anyways, you might try focusing on keeping your teeth apart as much as you need to, until you've retrained your jaw back to where it's supposed to be. And night guard mouthpieces are available if that doesn't work, also.

On the other hand, something else may be going on that you can look into as well (it sounds like you already have done some of that).
