Canker sores can be incredibly uncomfortable, especially when trying to eat certain foods. And though there really isn't any known cure for them, there are several ways of reducing their staying time.

The tried and true method of swishing salt water around in your mouth is always an option. However, if you really want to get rid of that annoying sore quickly, there may be a better option available.

According to an Israeli study, adhesive patches containing magnesium salts and citrus oils can heal canker sores up to four times faster than most over-the-counter products. Apparently, this combination helps form a protective coating over the sore, while at the same time having an antibacterial affect that helps get rid of the mouth ulcer in no time.
