That's not an easy ?: Sorry about that, but I'm certain a doctor will need to examine you to answer that question. What other physical symptoms do you have? How long has this been an issue? Any fever? Maybe mono? Maybe oral herpes? The yellow could be superficial growth of bacteria or damaged skin or it might be jaundice. So, in a nutshell this is a situation where exam is unavoidable if you want answers. Feel better! ...Read more

Mouth rinse: Unfortunately there are no good remedies for canker sores and causes are often unknown. The best treatments are usually just to treat pain, not to cure the sore. My personal favorite is what most call magic mouthwash. It is 1/3 Benadryl (to reduce inflammation), 1/3 viscous Lidocaine (to reduce pain), and 1/3 maalox (to make it stick). You rinse and spit or swallow. Ask your dentist about it. ...Read more
