Great for mouth sores or irritation

I get canker sores or irritated spots in my mouth from dental work, certain foods, etc. My dentist recommended this oral rinse and it works great. Often after one use the problem is resolved.
You don't need a lot, and I often use it once a day. You can't eat or drink for 30 minutes after washing your mouth out, so I found it worked best to use it at night. It doesn't taste great, but it works!
