Great Product

pabloDecember 29, 2025

Used it and the results are very clear and noticeable. Maybe they don’t last as long as I would expect but it might be for not having the best care, will use them again and make an update or other review. Read more

Really great stain removal and teeth whitening

LARRY PFebruary 9, 2025

Absolutely love this product. I have worked in the dental industry in the past. I was a huge fan of night white ACP. Recently, have tried this brand from my orthodontist, and the results were so quick and painless. I instantly went to Amazon to buy more. To my surprise it was very affordable. I would recommend doing in the evening after you have finished eating and can go at least 12 hours before eating or drinking anything. When bleaching your teeth, you are roughing the surface of the tooth enamel, which makes you more prone to staining. With that in mind, you have to keep that in the back of your head for what you plan on eating the following week. If you drink coffee, you have to drink it through a straw and make sure you brush your teeth right after pasta sauce, beets, any food that is prone to staining will stain in your teeth after their bleached. I remember telling my clients that if you were to wipe it off of an untreated quartz countertop and it would leave a stain, it would leave a stain on your teeth as well. That all being said this was a phenomenal product. Please ask a professional for trays and do not overuse this as it can permanently damage your teeth and create extreme sensitivity, along with weakening the tooth structure that is with all whitening products even in office treatments. You should probably be doing whitening in stages and build up your tolerance. You could do 15 minutes one day and the next only be able to comfortably do five you don’t want to have super reactive nerve pain as it is one of the most painful pains. I know it sounds silly, but ask your dentist if you are a good candidate for teeth whitening. You may be a better candidate for veneers if your teeth are intrinsic stains, meaning the stain is from within. Read more

Yes!

After I use this I always get complemented by family and friends. It works and you can pick your strength in case you have sensitive teeth like me. You need trays that mold to your teeth. I got mine from my dentist Read more

Takes 2 hours per day

Good teeth whiting

T.BirdOctober 28, 2025

This is the second time I have ordered these. They work really well and people often how my teeth are so white. I use them for 2 hours, you can wear longer but my teeth are sensitive so I don’t want to chance any longer of a time. I have a tray from the dentist (which wasn’t cheap) I’m sure you could buy one at a store or probably even on Amazon. Read more

Same product as you buy from the dentist for a cheaper price.

not like it used to be...

SJ 85January 7, 2024

I have used this for years. Usually, 2 syringes over 2 or 3 days (to preserve my gums) would yield noticeable results. If I were going on vacation or had an event, I'd do it for 3 nights over 5 days and results were awesome. The last batch I received in Nov 2023 had an expiration date of Oct 2024. The packaging was sealed. When I purchased from my dentist, he always had it in the fridge and mentioned that prolonged the life of the product, so I always refrigerate after it comes. This last time, it just didn't perform like other times and there was little whitening. With a year before expiring, I don't know why, but also don't know how old it can be and still considered fresh. Packaging looked the same but syringes seemed a little smaller and a bit flimsy compared to the past. The little end tips used to twist off easily but this time, the whole end came off up to the barrel of the syringe and was difficult to distribute in the dental traps. Not cool. The missing info could be how the product is stored before delivery to the end user and under what temps it is shipped. I'm going to try the new "Opal" product this time. I don't know if it's the same product as before with new packaging, but it HAS to be fresher. Read more
