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

Bought the large bag. This will go a l9ng way. Expires in 2028 so good shelf life. I got the 44% Really Strong & sensitive to a crown I need replaced. Go very light & short time with applying. Says 1x weekly. I advise just that!

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.

Love them. Use them every day

I've been using whitening gel for about 10 years now and this is the best one that I've used including opalescent. This one is stronger than opalescent and has the same mint flavor.

I want to give this more stars, because there's a lot that I do like, but I have burns on my inner lower lip that are quite painful. I've been using whitening gel and my light for years and this has never happened before. I think it's probably because it's stronger. 🤷 EDIT: 2 WEEKS LATER: I find that it really burned the inside of my mouth, not my lower lip. It's pretty serious and it's scarring and very painful. I'm unable to open my mouth all the way, because of the pain.

This one's are not for someone who can easily not stand a bad flavor on mouth, doesn't have any flavors like mint or anything else you taste what it is, and is awful. It does the job tho.

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
