I order these for the animal shelter I work for. They're individually wrapped, which makes them perfect for fungal screening of every animal that comes in. Each gets a new brush out of the package so there's no cross-contamination. Perfect and inexpensive for this use. I also know of others who buy these to send to refugees and other areas where toothbrushes may be needed on an emergency basis, along with 99-cent scrub tops and pants. Really helps donation dollars stretch.
I've been using this strength of gel for about two years now, ordering it here. I use it with the strips that are already coated with gel but the OTC strips' peroxide strength is less and the coating is skimpy. I buy a huge chainstore's generic brand of whitening kit so the overall cost really isn't very expensive, considering the excellent price here.I just coat each strip with a good amount to cover it and press into place. I don't use so much that I waste it by it oozing out of the strip when I'm applying & pressing them firmly into place.The recommended time to leave this strength on is no more than one hour.I have sensitive teeth but this does not bother them as I follow up with a mouthwash that has remineralizing properties. I try to leave it in my mouth, swishing it around, for a full five minutes.The sryinges of gel that are not in use I keep in the fridge.I knocked this rating down because there are no instructions with it but really, let common sense be the guide. Ease of operation is a bit tricky at first until you get the hang of how best to work it.
This is just was too strong for my sensitive mouth & trays. My husband is fine though. We both add this to the top of our toothpaste each day and it doesn't burn at all... yet it still perfectly whitens since it's so strong. Will keep ordering because this system seems to work for us.
