allergic reaction while brushing teeth

Hi......for the past year I have been experiencing terrible gagging while brushing my teeth, that does usually cause me to vomit, which I believe may be caused by sinus drainage that only occurs when brushing begins. I have changed my toothpaste several times, with no resolution, and don't what to do. I am sure that I have lots of gum disease, and also have pain in several teeth. I currently have only state medicaid so I do not have dental insurance. Do you have any suggestions?

I would still recommend that you see a dentist to improve your oral health.  What is triggering the gagging though?  Is it the brushing in certain areas or is it a certain smell or odor that may be causing it?  A dental cleaning may help to remove any plaque/tartar that may be triggering it.

You can also contact your local dental society or dental school to see what can be done at an affordable rate.
