Great product. It works and yes it's strong, so if you want to protect your gums from being burned use some vaseline.<br />Apply with a Q-tip before using the first tray, by the 2nd application you will start feeling some sensitivity. If you ask me,<br />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<br />that my dentist offered.
