M.O.M. can help rid you of that canker sore.
Canker sores never come up at a good time – luckily it’s fairly easy to get rid of them.
Next time one appears try dabbing some milk of magnesia on it a couple times a day to speed up the healing process. This works because the milk of magnesia acts like an antacid, soothing the area.
While canker sores are typically harmless, it’s a good idea to keep an eye on them. See a doctor if you notice recurring sores, or frequent outbreaks, which might indicate a more serious problem.
