Hi baby lemonade. The LunaGaurd Nighttime Dental Guard will protect just as well on the bottom or top teeth. Note: Some users find that the bite guard snaps into place and stays more secure on the top teeth, as opposed to the bottom teeth. We recommend using it on the top teeth. If you have further questions, please contact us directly. Thanks!
Hi@@giao2380. When fitted properly and according to directions, the LunaGuard Nighttime Dental Protector forma a very good, semi-rigid, custom fit that when applied to the teeth, fits quite snugly and securely. Having sold and used the guard ourselves (for many years), it's our experience that the device would be very difficult and uncomfortable to even attempt to swallow. If we can help further, please contact us at info@macksearplugs.com. Thanks!
