Possible Results
with CankerZero

FULL ELIMINATION

of canker sores

75%

​approx. chance

Multiple research teams found around a 75% chance that canker sores will stop coming back with what you’ll learn in CankerZero.

Teams of scientists in different studies described results like this:

  • “Cured.” Around 75% of patients were “cured” of canker sores.
  • “Remission.” Canker sores were put into remission 75% of the time.
  • No Canker Sores. Around 75% of patients reached “no canker sore status.”
  • We call this most likely result “CankerZero Status”

Significant improvement

of canker sores

10%

​approx. chance

Studies showed about 10% chance that canker sores will become significantly better with what you learn in CankerZero.

This could mean:

  • Less Frequent. Fewer canker sores than you get now
  • Less Painful. Imagine a canker sore that was there, but barely hurt.
  • Faster to Heal. Instead of 14-day canker sores, they could be 10 days, 7 days, 5 days, or less.
  • Canker sores go from dreaded “mouth terrorists” to puny wimps.

NO 

improvement

of canker sores

15%

​approx. chance

Studies show about a 15% chance that canker sores won't improve—but it's still WORTH IT!

Here’s why:

  • Know Your Foe. Understand the important cause of canker sores
  • Empowered to Discover. Learn the facts so you can find your own solutions, instead of staying stuck
  • Might Improve. Learn new anti-canker sore habits that might stop triggering your canker sores
(no one talks about these “triggers”)
  • If you’re not satisfied with what you learned in the course, just send us an email within 30 days and you’ll get a full refund!
