Canker sores: Canker sores also known as aphthous ulcers will heal on their own in 10-14 days. There is not much you can do to make them heal quicker. Avoid hot and spicy foods, you can rinse with salt water or use any number of remedies from your local pharmacy, but only to make them feel better meanwhile. Some dentists use lasers for treatment. Personally, i don't think it's worth the trouble or the money.
