Brushing my kid's teeth used to be the easiest part of our routine. Then one day, he just stopped. I held him down and brushed anyway β€” and saw a red canker sore inside his mouth. He wasn't being difficult. He was in pain.

Here's what works:

  1. Find where the sore is. Different locations need different approaches.
  2. Switch to an ultra-soft toothbrush.
  3. Use warm water, not cold.
  4. Be gentle around the sore, but don't skip it entirely.
  5. Follow up with alcohol-free kid's mouthwash.

If it's really bad: try rinsing with warm salt water, using gauze to gently wipe teeth, or chewing xylitol gum. Or just wait for it to heal β€” canker sores usually resolve within a week.

What methods have you used? I'm curious how many people are in the "wait-it-out" camp.
