## Description

desertcart.com: Opalescence 20% Teeth Whitening Refill Kit (4 Syringes) Carbamide Peroxide. Made by Ultradent, in Mint Flavor. Tooth Whitening Refill Syringes - B-5196-4 : Industrial & Scientific

Review: Really great stain removal and teeth whitening - 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 desertcart 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.

## Questions & Answers

**Q: Does this help dark stained teeth. What is the time frame of completion.**
A: The key to tray whitening is consistently using the product day after day, or every other day if sensitivity is a significant problem, until you get the desired results. This is literally the product my dentist sold me from his office. It has a consistency that it will provide a thick, sticky substance. It is best to use professionally developed whitening trays versus and other method. If the stains are gray in color, they do not respond as well to whitening, but staining from coffee and soft drinks or smoking, it absolutely will. If you have no experience with whitening, you may want to start out with a lower percentage of the active ingredient carbamide peroxide -- otherwise, if you have healthy teeth and do have have professional whitening trays and little history of any extreme sensitivity or gum problems, you may safely use this product but you may want to use for less time to start out as you become accustomed. A majority of the other products sold for whitening are cheaply made, watery in consistency, and are more likely to drain from the trays and burn your gums (which is incredibly uncomfortable, especially if you have not tolerance for it). There are stronger preparations, although I do not believe Opalescence carries it for at-home use, that offer 44% and while these allow for shorter wear times, they really should be used under the supervision of a dentist. Other products do not contain potassium nitrate and fluoride to reduce the chances of sensitivity or the sensitivity that you do experience, which is a predictable outcome of dental whitening, as you are literally applying an oxidating agent to your teeth that seeps into your animal and oxidizes, sweeping away the stain, and as such, whitening can be hard on the enamel, so the fluoride will help remineralize your teeth while also whitening them (almost akin to holding a ladder for someone climbing the ladder -- while you are not climbing the ladder, you're still helping). I highly recommend that you ask your dentist for a prescription for Prevident which contains 1% fluoride solution that you can brush with or brush with your regular toothpaste, rinse, and brush with Prevident or leave on -- or brush with Prevident and rinse and then brush again and leave it on. You can also purchase Gel Kam which is a half-strength formula available without a prescription but it is a gel and note a paste. You can use it after brushing and leave it on your teeth prior to bed or you can use it in whitening trays but be careful not to overfil or it will burn your gums (somewhat uncomfortable) following treatment. Finally, in dealing with sensitivity which I know diverges from your question (I just believe there is so much more to this than simply whether or not it will help with dark stained teeth), you can purchase a reminalizing gel on Amazon that will contain potassium nitrate that should help with sensitivity and provide protection.

The amount of time that you have to use the product will depend on a number of factors, such as how often you use the product, how long you wear it for, the shade of your teeth, your desired result. You will notice results rather quickly but whether or not you are happy with those results will determine how long you whiten them. You can go too far, however, and teeth, which are translucent, will take on a blue-ish tint and look unnature and unhealthy. 

I wanted to provide these points for anyone out there who is hoping to whiten their teeth to help them understand what it is they are taking on. I realize the original post is from 2014 and he or she has almost certainly has acquired the answer. I may have wasted my time as there are several other answers that are shorter and more to the point, but if this helps anyone, it's worth it.

**Q: what is the bleach?**
A: This was recommended by my dentist. It is a high % but you only need a drop placed inside the personal dental molds. You wear it for only 30 to 60 mins. Do this every couple days. Give up the smokes, brush after coffee and red wine. Then smile...smile...smile!

**Q: Does this product use 15% carbamide peroxide -or- 15% hydrogen peroxide as the whitening agent?**
A: I just looked at my bleach syringe and it's 15% carbamide peroxide. This is "Professional" grade whitening gel. I originally got this product from my dentist, along with my bleaching trays. My dentist sells a 4-pack for $40, so this a great deal! I only purchase this gel from Amazon. A helpful hint: my dental office says to store the unused bleach in the frig, to preserve/prolong freshness. I hope this helps you.

**Q: Do you brush your teeth first**
A: Yes, you brush your teeth first, floss, no mouthwash, apply Opalescence PF 35% between 1 or 2 hrs if you can stand it (I do ). When I am done, take outtrays I clean them softly with the toothbrush, rinse your mouth only 2 or 3 times to get the access gel off, no mouth wash. 2 things I have found out,Relief ACP is a gel almost like the whitening one but this is to soothe your gums and teeth sensitivity and it is great because it actually makes your teethshine. Right after I whiten, rinse, I put the Relief ACP in the trays and keep them up for an hour.Also Colgate has a special toothbrush called Floss Tip Bristles, it is extremely soft bristles and it is great in case your gums are sore or burn, great investment. One more Tip Using Rembrandt Deeply White mouthwash will actually help remove wine, cigarette, and other dark fluids that may stainyour teeth in between whitenings. Good Luck !!!
