is there any new thinking on treatment of canker sores?  i have another one (though i dont get them as often as i used to, since i switched to toothpaste which does not contain SLS), this time behind my upper jaw between my cheek and soft palate, tucked away.  my jaw muscles are very sore now, and opening my mouth is a painful struggle.  id love to get rid of this thing ASAP.
Thanks for your query, I have gone through your query. The recurrent authors ulcer can be treated by using topical steroids like triamcinolone acetone 0.1%, apply 3-4times daily after food. Use topical analgesics and anesthetics like Anabel gel 3-4times daily before food. I hope my answer will help you take care. Consult your oral physician to rule out this authors ulcer from allergic dermatitis since you are giving history of changing toothpaste.
