Questions people ask

Does it really work?

Light therapy on mouth sores has been studied: in one trial sores healed in about 3 days instead of 9, and a 2024 review of 21 trials found less pain after treatment. Those studies used clinical lasers and results vary, so you have 30 days to try it.

How long and how often?

About 60 seconds per sore, around 3 times a day, a few hours apart.

Is it safe for kids?

No drug and nothing to swallow. An adult should hold the pen for a child and never shine it at the eyes.

How does it charge?

USB rechargeable.

When should I see a doctor?

If a sore lasts more than 2 weeks, is unusually large, or comes with fever.

What if it doesn't help?
