Review (5/5): Great product. It works and yes it's strong
Great product. It works and yes it's strong, so if you want to protect your gums from being burned use some vaseline.
Apply with a Q-tip before using the first tray, by the 2nd application you will start feeling some sensitivity. If you ask me,
I think it is worth it. I really don't want to spend $300 at the dentist when I can do this at home for $60. Same product
that my dentist offered.
