Bc if they are they expired 2 months ago** A: I bought mine last year and they worked great. Just like what I purchased from the dentist. They may be new ones. I’d ask the seller. **Q: The product description in the title reads, “opalescence quick rf 45%” instead of pf 45%”. Is “RF” a typo? Is this authentic opalescence PF 45%??** A: It must be a typo in the ad. I just looked at the actual packaging I received from my order and it says PF. It's in opalescence packaging and long before the expiration date. I've order this from this seller several times and never disappointed. **Q: %45 is this the highest strength** A: Not sure, but this was the strength my dentist recommended, anything stronger makes your teeth more sensative **Q: is this 45% the same manufacture as the 35%?** A: Yes! ## Customer Reviews ### ⭐⭐⭐⭐⭐ Know what you are doing and you will get great results *by on Reviewed in the United States October 30, 2025* This whitening gel is the same one I used to only be able to get through my dentist. I'm happy I can now buy this through Amazon. It whitens my teeth better than any other product out there.In the past, we had to buy teeth whitening trays from dentists. Now there are lots of options for inexpensive do-it-yourself trays that are just as good as the professional ones that will work perfectly with this gel. Be careful if you are not used to this type of whitener, 45% is very strong, so it should be left in place for a short time (the seller recommends 15-30 minutes). Trust me, that is long enough, and you will get good results without needing to go longer.And, make sure you do not let this sit for any time on your gums. As with any whitening gel, it will create a little ulcer if left too long. Remove the tray, wipe the gel off your gums and the corresponding area of the tray the minute you feel any burning, then put the tray back in.My dentist taught me to put only a small dot of gel at each tooth tip in the tray. Do not draw a line of gel along the inside of the trays; that's way too much gel, and do not place the gel dots at the top edge of the trays (where the gums are). Trust me, I've been whitening for many years. A little bit of gel goes a long way, and the gel will foam and cover your entire tooth surface. Four tubes of gel should last you approximately six months, even with weekly use. You also most likely do not need to whiten the tongue side of your teeth or your molars. Granted, there are a few folks who may want to.We've been told veneers cannot be whitened, but I have not found that to be false. My front teeth have had cosmetic work, and this gel does whiten them. There is a little bit of difference in the shade from my real teeth and the cosmetic work areas, but that is less obvious when I'm whitening on a regular basis.If the gel consistency isn't ideal, try storing the tubes in the refrigerator before use. At the very least, store the tubes there and store the one you're currently using at room temperature.Whitening gels can cause dental sensitivity; try brushing with a toothpaste for sensitive teeth, which will help with that. If you still have sensitivity, try their 10-35% gels. ### ⭐⭐⭐⭐⭐ Great home teeth whitener product really works *by on Reviewed in the United States May 15, 2026* I have been using opal essence teeth whitening for a couple of years I started with the 35%, but now I'm using the 45%. Doesn't take as long you do have to be careful for sensitivity afterwards I always use the sensitivity toothpaste but love this product and the results you get in a short time I always keep this on hand because drinking coffee and spaghetti sauce and things like that just naturally stain your teeth you can use this product and see the difference after one use would highly recommend these syringes keep them in the refrigerator in dark bag... ### ⭐⭐⭐⭐⭐ BUY IT. *by on Reviewed in the United States June 1, 2026* This is the best. I always thought this was RX only! This is the bees knees of whitening. 45% is strong, and I recommend using a sensitive teeth toothpaste while whitening. This will last you forever! So get this size. Not the crazy big one. Not needed.I let my beautiful teeth go after 3 pregnancies and depression. I often find myself upset.NOW, i can get the front fillings filled and still have white teeth.FYI front fillings won’t whiten.Whiten before treatment! ## Frequently Bought Together - Opalescence 45% Syringes Teeth Whitening Gel - with PF - (4 Syringes) Refill Kit Carbamide Peroxide.
