Fast and effective whitening gel

My dental office ran out of the whitening gel that they sell that was a different brand (vivastyle) so they told me to try this brand and to buy it online. I used it for 6 nights before I got my desired shade. It worked much faster and I had great results and was able to get next day delivery of the gel. My dentist office gave me the yellow syringe tips to use that I attached a picture of and I highly recommend using a tip like this so that you don't put to much gel on the trays. I tried not using it one night and just using the syringe it came in and I had a lot of sensitivity. The expiration date was a little less than 18 months out. I likely won't use it all by then but the price is great. I do wish they made a gel for use afterwards to reduce risk of sensitivity. I know there's some in the gel but I've liked using something like this in the past.

I wish it were a bit less expensive. I does whiten teeth, if you follow instructions. I have my own fitted teeth trays.

Works 100% after 2 applications

Dr Dentist recommended and I purchased from him. They are much better priced through Walmart quality products. I used me in me teeth trays.
