Opalescence20% Teeth Whitening Refill Kit (2 Packs / 4 Syringes) Carbamide Peroxide. Made by Ultradent, in Mint Flavor. Tooth Whitening Refill Syringes - B-5196-4

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.

Been using these for years. Dentist approves. Be careful not to add too much it can burn your gums. Yes I’ve done that by mistake.My teeth are white and I use it twice or three times a year. No tooth damage. Quality product I used to buy from my dentist.Just make sure you have your own teeth guard to wear. I use it for 45 min.

Much more affordable thank buying from the dentist! I have used these for years and they work so well. I whiten my teeth for a day or 2 every 3-6months and my teeth stay white! I dont have any sensitivities to this either which is a must. My teeth are sensitive to cold and other things so finding a whitener that works and doesn't hurt was difficult. These are much more effective and easier to use than the whitening strips. The taste is good as well.

Packaged arrived perfectly packaged and will probably be just fine, I wish I would've read the package insert prior to purchasing this strength. I was hesitate to purchase the 35% because of a horrible experience with Zoom a long time ago, but having to sit with this for 2-4 hours is a bit long for me without comfortable trays. Will definitely purchase the stronger % next time if it works well.

Great whitener!

Good and works

Doesn’t feel or taste the same as one’s from dentist. Isn’t kept refrigerated while shipped, could be why.

This teeth whitening gel works very well! For the best results, use it every other day for a week. However, it is not recommended for those with sensitive gums or teeth. Be sure to follow the instructions carefully and avoid wearing it longer than directed, as overuse can cause significant sensitivity.A personal tip: I apply a thin layer of coconut oil to my gums with a Q-tip before using the whitening gel. This helps protect my gums from irritation.Overall, I’m very happy with this product and highly recommend it to anyone looking for an effective teeth-whitening solution!
