Opalescence 45% Gel Syringes Teeth Whitening Treatment - (8 Syringes) Refill Kit Carbamide Peroxide. Made by Ultradent, in Mint Flavor. Tooth Whitening 5359-4

This whitening gel works very well! To increase its efficacy, I use 4 dental cotton rolls under my cheeks as well as a dental mouth widener which helps me accurately apply the gel to my teeth. I loaded the syringes into an empty touch up paint pen, which I find works better than inserting the gel into a tooth tray. That way, I can paint the gel directly onto my teeth. The last step that I do is to use an LED tooth whitening retainer. I keep the gel on my teeth for 1 hour. After 1 hour has elapsed, I remove the LED retainer, remove the dental rolls, and carefully brush the excess gel from my teeth with a spare toothbrush. My teeth are 6 shades whiter after doing this process daily for 2 weeks. I advise immense accuracy while applying the gel, because getting it on your gums will burn significantly.

Good product

My teeth whitened at least 2 shades. Not sensitive much.

These work! I didn’t know they had started making a gel with higher intensity until I checked Amazon. Lower dose wasn’t working at all for me anymore.It is strong. So be careful. Use sparingly at first.

Great whitening

This stuff really works. If you're on the fence, please do yourself a favor and go for it.I have been putting the gel in trays specifically made for my teeth at the dentist's office for 30 minutes a night. It's only been a week ,but the difference is noticeable. Just be aware that you may experience some gum/teeth sensitivity. If this occurs, take an over the counter pain pill and you'll be golden.

Not the same quality as from the dentist. Not even close.

It is used by my dentist and well recommended I tried and like the outcome
