10 Syringes (3ml) New Strongest 44% Carbamide Peroxide Teeth whitening Gel (Mouth Trays NOT Included)

These whitening gel syringes hold plenty of product to use over several applications. Great value for the price and it works great to whiten my teeth. I use this with the led light

Well, this does work. It’s good peroxide for whitening your teeth. I just put it on my teeth with my fingers and then chomp down on a whitening device and plug it into my phone. I also put it in my customized teeth, mold when sleeping. I just keep a syringe in the car or whatever and I’ll stick it on my teeth when I’m driving I put the plastic inserts in my mouth and then I can be whitening my teeth while I’m driving around.

I recently got my braces off a few months ago (I'm an adult lol) and I had pre-made trays. My dentist had given me a whitening gel to finish the desired look. I never had any issues with it. Even though he told me to use it for an hour each day, I usually ended up sleeping with them in. I recently ran out and he is kind of far and not sure what the charge would be for another syringe so I just figured it would be quicker and cheaper to order online... First of all, this stuff is strong. Like someone else said, there is no precision pinpoint tip that screws on like the one from the dentist. So it is a little challenging to get the tiny amount that you need. It was tough to last for 45 minutes. For me, it wasn't constant burning. But certain spots were more sensitive than others and my fillings felt like someone was jabbing a pick in there... that's probably because they need to be fixed but still that's how strong it is. Now yes, when I took them out I definitely noticed they were whiter and I didn't have yellow teeth to begin with. I did notice though that I did indeed get a chemical burn because some areas of my gums were white. I honestly had no idea what it was until I googled it. Anyways, I just so happened to have to go to the dentist today and I shamefully told him what I did. He said it okay to buy it online but then I told him what percentage it said, his eyes widened and he chuckled. He said even if you had been whitening consistently for years, 44% is still too strong. He said in all his years the only time he's ever seen a perctage that high be used is if someone got a root canal and the tooth needs to be whitened from the inside. He also reminded me that whitening is about removing the stains layer by layer after consistent use, not just one quick strong session. I was being impatient and ended up doing more harm than good because my teeth are very sensitive today. Also, yes it is grainy like sand and does taste like poison. I didn't feel comfortable swallowing my spit unlike the one from the dentist. Moral of the story, it works but the tortoise wins the race.

Great price, better than from my dentist. It works very well.

This is amazing! Noticed results after one use. Would definitely recommend. Much better than whitening strips. Will purchase again.

This product is very strong, will burn your lips and gums if product gets on them. Be careful.

This works well for me. I leave it in for about 15 minutes while I clean up and shower and then rinse. It does not make my teeth blinding white, but it does lighten them up nicely.

I have went through two syringes with no change(ALSO USING BLUE LIGHT). I have also used real professional whitening peroxide with the same srtrength from the dentist which caused the gums to burn immediately if you got it on them. This did none of that. I am going to try it once more time after this exchange to see if I just got a bad batch or something but this is not what I ordered. Edit: Received the exchange and it was of very little difference besides just a little bit of burning on my gums. This strength is definitely nowhere near 44% and the gel itself has crystalized leaving it chunky looking not smooth looking. As much as I need teeth whitening for my 51 year old mild coffee stained teeth this isn't it and will be asking for a refund.
