Review on 🦷 SenAllis Cosmetics Teeth Whitening Gel: Fast & Effective, 35% Gel Syringes, Refill Compatible with Hi Smile Teeth Whitening Kit, Beats Teeth Whitening Strips by Esperanza Hernandez

This stuff really works. I've been using this for years. The best way to really do this is to brush your teeth with whitening toothpaste first, then fill the bowl and leave it in while you shower, then towel off and get dressed (about 10-15 minutes). After spitting it out, brush your teeth again and then rinse your mouth well. Try not to drink anything that might stain your teeth for an hour. You can also use hydrogen peroxide (gargle for 15-30 seconds), but the next day. two sensitive teeth do it at once. but the HP beat is amazing (got advice from my ex-girlfriend who works as a TV news anchor and whose teeth were amazingly white).
