It took a while to get but a I am very pleased with my new retainer. It’s much more comfortable than my old one, which was bought from my dentist and a lot more expensive.

Easy to squirt some into the guards before I put them in at night. It takes a bit to get used to the sensation but keeps moving the guard and my teeth clean.

"Dental appliances collect plaque and bacteria, and a quick rinse under water isn't enough to clean them. Remi's Dual-Action Foam cleans your night guard or retainer and whitens your teeth in one step while you sleep, using a gentle, well-established hydrogen peroxide formula, without adding anything new to your nightly routine."

SC-5 Dr. Brian Wu, MD, PhD, MNM

"For patients who already wear a night guard or retainer, Remi's Dual-Action Foam does two jobs at once: it cleans the appliance and whitens your teeth overnight. There's no soaking or scrubbing, and no extra routine to remember. Most people notice a whiter smile in about three weeks."
