Teeth Whitening Gel Refill Kit Syringes (8 Pack) - 35% Carbamide Peroxide Teeth Whitener - No Sensitivity Teeth Whitening Gel for Trays - Teeth Whitening Kit Syringes for Brighter Smile

These are great, works perfectly

I was nervous about this and it exceeded my expectations. I have only used strips and was just so underwhelmed by them and hated the way they felt in my mouth. This was easy peasy and I’m happy with the results after my first use. I think the key is to go light on the gel in the guard the first time especially to make sure it doesn’t get all over your tongue and gums.

Does seem to whiten, has an pleasant chemical taste, like an adhesive. My mouth didn't feel fresh after several hours, as if I hadn't brushed, flossed, & waterpik'd prior to using, so that was unusual. Next time will go back to a minty type. Has one tiny, transparent tip attachment with a miniscule cap, and this attachment doesn't have a storage position in the box so is easily lost especially upon opening the box, after which you won't be able to finely dispense the gel into a whitening tray, instead you'll dispense the gel in blobs that waste the gel and leave too much gel on your gums after fitting the trays. There's also not room in the box to leave the attachment on one dispensing syringe as the syringes fit only in a fixed position in its slot.

I really liked this gel because professional teeth whitening is very expensive, and with this product I was able to do the treatment easily at home. It’s simple to apply, caused no sensitivity, and the results show gradually. My husband also used it and the difference was more noticeable for him since he drinks a lot of coffee. His teeth whitened significantly more than mine. Great value for the price and I would definitely recommend it.

I am beyond impressed with my teeth whitening results! My smile is noticeably brighter after just one session, and the process was quick, comfortable, and painless. There was little to no sensitivity, which I really appreciated. I feel so much more confident smiling and will absolutely be returning for maintenance treatments. Highly recommend to anyone looking for safe, effective whitening!

On my first try with this gel, I decided to load the trays up and take a shower while I let the gel work. As soon as I stepped into the shower the flavor in my mouth exploded with a sicky-sweet taste that intensified as I went along. I couldn't swallow it and I just gagged for a bit. Yuck! I guess it mixes with my naturally sweetness and switches flavors. So weird! Note; I CHANGED my rating up to 3 stars as I discovered that if I close my mouth with this- my saliva swells a lot and then the flavor changes. But if I mouth breathe while treating teeth (keeping them dryer) I can manage to treat for 10 minutes before I can't tolerate. With practice I expect to succeed in getting my teeth whiteer.

I am really enjoying this whitening gel… unlike others it doesn’t cause pain in my teeth or gums

Does not live up to the product promises it makes at all, does not make a noticeable difference. The light battery doesn’t hold a charge and will not stay on during use constantly switches on and off while trying to use.
