Try brushing your teeth with baking soda, non fluoride toothpaste, and a few drops of Miracle II soap. It's been helping me with my split/cracked lips. Also applied a solution of H20 and baking soda to lips directly... not too long then wash off. Baking Soda is supposed to kill candida.
Also regards to the guy who say's Miracle-Mineral-Supplement drops... also doing that. Taste awful but really helpful. Lastly, try to stay away from sugars. Candida feeds off it.
Also use calendula cream on mouth to soothe dryness.
Other useful tips, check PH balance and mercury in system...
Can also try to cleanse your system using a technique called 'oil pulling.'
