Colgate Optic White Gel Professional Whitening Take-home Kit (9%)

I last purchased this a year ago and am surprised at the number of 1 & 2 star reviews that have popped up since then. Right in the description it states: CUSTOM TRAYS ARE REQUIRED FOR USE. Personally, I use my Vivera retainers.Also, one person commented on how there's only 4 applications? Even if you're extremely generous with the amount you're putting into your trays (which is pointless because your teeth are going to force it up into your gums and no one wants burnt gums), you're going to have 12 applications (3 ml * 4 syringes = 12 1 ml applications).This product gets 5 stars because it is: less messy than strips, doesn't burn my gums because I control where the gel goes, isn't a counterfeit product (YET), and whitens my teeth well.

Happy new year,I received the package one day earlier than expected and opened the box immediately to check the expiration.2022 expires so I am good to go!4 tubes included and I would recommend getting a mouth tray from your dentist so it fits perfectly and remember a little goes a long way, you do not want these products on your gums. Being 9% the process is a bit slow but it took me many years to get to this point and this seems to be the least invasive from what I have been hearing.Keep Smiling!

This product is the same you get at the dentist’s office for a quarter of the price! I had my teeth professionally whitened, and continued to buy the whitening gel (this exact product!) for $80 for 2 vials. I get 4 of them for half that price here! It’s the same strength, 9%, I got at the dentist. Fantastic deal for the money, and my teeth are so white!!

Used to get this through my dentist...(they have to make the form for your teeth) & it costs $40.00 for one box. This is for 3 boxes. Same exact stuff. Exact. At least when I am doing this review, price was $40.00 for three. Hope prices don't go up. Really works wonderfully. My hygienist when I used to reorder all the time from dentist, said the proper way to use this product is to use once a month, for 5 days in a row. "A bomb whitening" she called it. I can tell the difference in my teeth being so much whiter this way. I used to not be able to tell a difference. Now they get so white they almost look like they are too white. haha.

Lindo y cómodo

These are amazing. They actually work. My young son had staining from medicine when he wasn’t event and it’s very self-conscious about his teeth. We tried this and we could see a difference in just one treatment.

Amazon retailers keep increasing in the price. It is about $20 more than my first order. My last two purchases were for touch ups.As far as the product goes; I trust Colgate. The Whitening system worked quickly and with little sensitivity. I think my dentist initially said I went 6+ shades lighter! After leaving the trays on for 30 mins a day.No light is required.

had to get the trays separately zzzzzzzzzzz///
