Salt water swish: Early on, you can try a salt water or hydrogen peroxide swish and spit. If the symptoms persist past a few days or recur frequently, see your dentist or doctor for an antimicrobial mouthwash, cortisone medication, or other solution.

Low acid diet: Avoid acids such as coffee, tea oj etc... Use mylanta or some other liquid antacid after you eat and before you go to bed. Take 1 tablespoon and swish it around for 1 minute and spit it out. Decreasing acidity in the mouth helps tremendously.

L-lysine: Try a lysine gel cap pierce it and put the gel on your sore. Anti-viral creams like Denavir (penciclovir) can also be very useful.

Try Zilactin B, : An over the counter medication found in pharmacies. Dry area, apply thin layer, let it dry and turn white. Your dentist can prescribe a steroid in a delivery vehicle called orabase. Rx for that! avoid toothpaste with sodium lauryl sulfate which can help cause. Avoid acidic foods. Be careful brushing not to gouge tissue. Lasers work very well, hope your dentist has one. Eat healthy! good luck!
