my boyfriend has bad breath through his nose. I always get sick (cold)after seeing him.?

i’ve never known someone who had bad breath coming from thier nose. It doesn’t really smell bad, but their is an odor. I heard it has to do with sinus infection. After one week of being with him, I now have a very sore throat and phlegm and been very tired that’s been goin on for 3 weeks. Do you think I got it from him? He says he doesn’t have any symptoms.

Sinus infections are not contagious so if that is what he has, then you should not have caught it. You may have gotten a cold. In reference to the odor, have him gargle mouthwash (Listerine is a good one) to kill bacteria.

My 3 year old son has had bad breath for 2 days now and no matter what we do it does not go away?

What can it be from? We brush his teeth 3 times a day. He has no cavitys. His teeth a perfectly healthy. It seems like the smell comes out his nose too when his mouth is closed,Like when he is sleeping. He has never had anything like this before. Any suggestions on how to get rid of the bad breath? Oh and I cant give him mouth wash he is to young.
Thankyou.

Is he well hydrated? Not drinking enough water can cause bad breathe, otherwise I have NO idea..I’d def call your Dr. to make sure it’s nothing serious. Good Luck!!!!
