About CankerScience

I'm Tom. I've had canker sores for more than 20 years, and I've tried just about everything: Debacterol, silver nitrate, Kenalog in Orabase, prescription rinses, patches, professional laser treatment, at-home red light therapy, and every home remedy I came across. A few helped. Most didn't. Almost none came with a straight answer about why.

What I kept running into is that canker sores get brushed off. They're “just” mouth sores, so there's little research money, few specialists who focus on them, and a lot of advice online that's outdated or made up. Meanwhile, people who get them often are eating around pain, losing sleep, and being told there's nothing to be done.

I built CankerScience to be the resource I wish I'd had: what the studies actually show, which treatments have real evidence and which don't, and plain explanations of how each one works.

I'm not a doctor or a dentist. I'm a long-time sufferer who reads the research. Every claim on this site is cited so you can check it yourself, and when the evidence is thin, I say so.
