Bright White Smiles - 35% Teeth Whitening Kit - Tooth Gel Whitener and Trays Included - Made in The USA - Ships from Oral Care Dental Laboratory

I liked how easy it was to use and the effectiveness of the product

rubber plunger in syringe degraded and "melted" into gel making it unusable. Maybe had 2 syringes that were usable, waste of money.

Tips for usage Boiling the trays is more like 5-6 seconds not 3. Do one at a time; press firmly all around your teeth with both hands. Do not use an entire applicator per use. Use half an applicator for two sides. Put a bead around the front. Don't try and fill the tray. Don't do it every day. Your gums can get irritated Biting down on a wash cloth between the two trays helps with the saliva and gel accumulating in your mouth. Otherwise you'll be drooling and spitting for the entire 15 minutes. My gel often has black contaminates in it. Seems harmless. Perhaps the same material from the rubber plunger. Also a large amount of air pockets instead of gel. Thus four stars. It is a cheap set.

It is by far the most reasonably priced teeth whitening and the results are GREAT !

Four uses so far and no whitening yet. I don't know if the peroxide included with this cheap kit will eventually work, so I'll update my review in a month after I've applied it a few more times. There's definitely a fair amount of gel included with the syringes so I'l try to be hopeful. Until then, I'll offer that the mouth trays form really well if you let them soften enough, then quickly put them in your mouth, push them tightly in place and bite down a bit. For some reason when you pull them out of the boiling water and quickly put them in your mouth, they're not scalding hot as you'd expect. So let them get very soft. Also, using this kit doesn't burn my gums hardly at all (a tiny bit though.) Maybe that's why they haven't brightened my teeth at all yet because the peroxide formulation is weak. How much peroxide is contained is one thing, but there's good (strong) peroxide and bad (weak) peroxide. This is a particularly weak formulation, but again, I'll be happy if my teeth eventually whiten after four or five more attempts.

I first thought each syringe was single use. But they are like 4 uses each. The tray molding was quick and easy. I have a little bit of a sensitive spot towards the lower back so I just don't put any of the stuff in that area of the tray. I put them in for 15 minutes.. have a tissue handy, as there is some drooling haaha. After the 2nd or 3rd use I noticed my teeth whiter. Now I use it about once every 2 weeks to maintain.

I bought these to stock up on my supply and went to use them later and each one of the syringes had black floating particles in them. Of course, the return window has closed so now I am out $20+ .

They do the job

It's effective, unlike some other products, provided you follow the instructions. It's certainly made my teeth noticeably whiter.

Works great and seller sent extra.

This product burned after 2 seconds from application, even though i applied less then in instruction.

it's really big!

Work well on teeth but is very strong on gums. Will burn your gums. Use a few days take a break then use again days later.
