Opalescence Gel and Opalescence GO is one of the largest authorized retailers of Opalesence.  The following information is presented in consultation with Ultradent, the maker of Opalescence.

PLEASE NOTE: Crowns, Bridges, Veneers, Fillings, and other dental restorations will NOT change color from tooth whitening.  Whitening products will have no effect on these items.

Whitening is a highly personal procedure with diminishing returns as you approach the whitest your individual teeth can get.  That means as your teeth get whiter, you will see less, or slower, increase in whiteness.  It is up to the customer to properly store and use the materials properly.  A properly constructed tray must be used.  We suggest dental professional instructions.  It’s important for users understand the whitening procedure and have realistic expectations of the outcome to be pleased with the final result.  While we aim for your satisfaction,  we do not warrant your satisfaction with the materials nor the results.  I'm sorry, but the item is not returnable once opened.  Please carefully read this information for your specific product to obtain the best results.

Your refill kit purchase is to be used in well fitting, properly made custom trays.  Please have your dentist make a professionally molded tray made of your teeth to use with this product. If you do not, you will probably be dissatisfied with the results.  Your trays will need to be updated every couple of years to maintain an adequate fit.  We do NOT recommend using Invisalign or retainer trays, which go past the teeth onto the gums.  The trays should not touch your gums.  If they do touch your gums, gel will get on your gums and it may cause burning or stinging.  I suggest a consultation with your personal dentist to review your trays and needs.  DO NOT GET GEL ON YOUR GUMS

From flavor to flavor and depending on the filling process, Opalescence syringes can be found with no bubbles or with many small bubbles. Bubbles in the gel are a normal part of the production process. Many of the pictures in our literature and catalog show the product with many small bubbles. These bubbles do not result from peroxide decomposition in the syringe; they are simply inherent in a thick formulation such as this.

The gel does not need to be refrigerated for transport and delivery, however refrigeration for storage is recommended to extend shelf life.  Product life, expiration, is approximately 1.5-2 years from purchase.

You MUST start with clean teeth.  Go get a dental cleaning.  You can’t whiten tartar and plaque!

The following review are several helpful hints from product reviewers:

This product works great. The following are the time of use for the various concentrations:


Opalescence 10% for 8-10 hours or overnight,

Opalescence 15% for 4-6 hours,

Opalescence 20% for 2-4 hours,

Opalescence 35% for 30 minutes.

I would recommend that new users keep the solution on for less time in the beginning, gradually building up tolerance. If the 35% product comes in contact with your gums it will sizzle or put a little bit of old fashioned Vaseline on your gums to protect them. Easy. This is much less, or not at all, with the 20% or lower concentrations.  If your gums are burning you are using too much gel or ill-fitting trays.  DO NOT GET GEL ON YOUR GUMS

If you leave 35% on too long you will experience some sensitivity. It may also turn your gums white.  The sensitivity goes away in a day or two, no problem. After using it a few more times, will be able to leave it on longer with no sensitivity whatsoever. The main benefits of using the stronger 35% solution is reduced tray wear time.  The benefit of lower concentrations is less sensitivity.

Since you won't be licking your lips or swallowing for a while, I like to apply a bit of chapstick to my lips, and have a good drink of water before getting started.

The PDF instruction sheet from the Opalescence website also states that you should use approximately one third to one half (total) of a syringe worth of solution to fill both trays. Good to know.

To target specific stains, add a little extra to that spot on the tray, and I apply a bit of solution directly to my teeth. The syringe makes it easy to put the product right where you want it. Solution is less important on the back of the trays, because no one is going to look at the back of your teeth.

All of our product is freshand direct from Ultradent, the manufacturer of Opalescence. Opalescence expiration date pressed into the syringe near the flange.  Depending on the product it will be a Lot code or date stamp you can see for yourself.

While “tingling” to bleach touching your gums is a frequently reported side effect, it is NOT  always experienced and is not  representative of bleaching efficacy nor freshness.  It is also more common with the 35% solution than the 20%.

1. Keep tooth bleaching product away from children.

Some discolorations may indicate the need for dental treatment other than bleaching. Porcelain crowns, veneers, and white fillings do not lighten upon bleaching.

3. Only intended for use by those with healthy gum tissue. Gum tissue irritation may result if used in individuals with periodontal disease

4. This product is NOT for overnight use.

5. Occasionally, some parts of teeth may bleach faster or less evenly than others. Results may be varied. In approximately 5% of the population, teeth may be resistant to bleaching. Bleaching teeth with large metal fillings may cause the metal color to show through the teeth.

6. Acidic foods/juices may cause sensitivity if consumed shortly after bleaching.

7. Do not use tobacco products or eat while bleaching.

WARNING: Some users may experience sensitivity or gum irritation, which if it occurs is most often mild and short lasting, but in some cases may require treatment by your dentist. If you experience significant discomfort, stop using this product and consult your dentist.
