Tara,

The ulcers are most likely the result of an immune response which could be linked to fluctuating hormones, inflammation and/or an underlying auto immune disorder, or stress which causes a major release of cortisol from the adrenal glands. You could also have oral shingles or herpes zoster. Has your dentist or physician actually examined inside of your mouth? Sometimes herpes can be present without the typical ulcers and usually it is diagnosed as such from the distinctive burning pain that is commonly associated with this virus.

The best thing you can do is eat a clean diet with plenty of phytonutients which are plant based nutrients. They need to be organic only so as to avoid contamination with pesticides, solvents or heavy metals. Avoid any foods that contain arginine as this will only make the ulcers worse. See this list..

Eat foods rich in L Lysine as this will help reduce the outbreak. See the list..

Rinsing with an oral mouthwash is not going to cure or prevent further outbreaks. It is immune related and you really need to check into why you are prone to getting them. Do you see a Naturopathic doctor? I can't remember if you said you did or not. That would be a good place to start because conventional physicians will only prescribe med and never bother to look for the culprit.

I hope your pain eases soon. Please consider looking into the cause of the outbreaks.
