Fifty-six million Americans suffer from canker sores. Theyre painful, nasty, and difficult to eliminate. Most canker sore products provide pain relief, but do not help heal the sores. The healthful, natural nutrients in Canker Care+ do both. Canker Care + is a soothing liquid that forms a protective gel on the canker sore. The soft applicator brush is gentle on even the most sensitive canker sores.
