## Description

desertcart.com: Opalescence PF 20% Teeth Whitening 8pk of Mint Flavor Syringes (4 Packs of 2 Syringes) : Health & Household

Review: Works great! - I had fairly white teeth before trying this but I am looking for bright white. So far I've used a little over 1 syringe approximately 6 hours in 3 applications each to both top and bottom. My teeth are absolutely noticeably whiter but not quite bright white, yet. I am almost certain I will be able to achieve the white I am looking for with this stuff though. It works great and is less spotty than strips. I bought 3 moldable trays on desertcart for $3 and they work great with this. $33 for opal + $3 trays, If I were to guess I think this will get a lot more use and whitening for the price vs strips. I certainly like this better than strips as well, the only downside vs strips is you can't really go out in public with a whitening tray in your mouth (also unpleasant with strips but with the clear ones you can manage), however I find the tray to be more comfortable than strips, they move around on your teeth, the trays stay put and little to none of it gets in your mouth. With strips I find I'm constantly moving them and touching them with my tongue. So far I've did my top 1 hr for the first application, 2 hr the next and then 3 hrs at night, all in the same day. My teeth gums were super sensitive the following day so I did the bottom the same way that day. Both top and bottom are whiter. This stuff does burn (just like strips) if it gets on your gums, The spot between my two front upper teeth got burned pretty severely the 3rd time I applied (I used more than previous applications). I stuck it out and the burn wore off after 2 or 3 minutes, but it was a pretty intense 2-3 minutes, and 3 days later that little area is still sensitive to touch. I'd certainly recommend these to anyone wishing to whiten their teeth. Great price and works great.
Review: Yes, you can find an expiration date! - Hi, thanks to somebody who posted a week ago, we can all solve the mystery of the expiration date of these teeth whitening syringes. Please see his review and rate him helpful as truly his information is invaluable (dated ~ July 30, 2013). For those of you not wanting to scroll back, each syringe is incised with a batch number which is a letter followed by three digits. The three digits are MM/Y where MM is the month of expiration and Y = 201Y = the year of expiration. I just received my eight syringes and they were all marked O065 which means the expiration date is in June 2015. That's almost two years off. I have used this tooth whitening system before, provided by my dentist who charged MANY times what you can pay for them on desertcart. Just like pet meds, we should all remember that you CAN shop around, even for prescription items (which these gels are not). Generally, the dentist or the veterinarian will be the MOST expensive place to find supplies and meds. So, I know these work. My dentist made custom trays for me years ago. I put the teensiest bit in each tooth's well - put it in the FRONT of the well, who cares if the back of your teeth are white, no one sees the backs! Put it in the bottom of each tooth's well, as when you squish the tray against your teeth it'll tend to squish out toward the edge of your tooth. Obviously, you want to use enough that the full outer surface of the tooth comes in contact with the gel, but not so much that it squishes all over your gums. I wore these overnight and found that my teeth were a little sensitive in the morning but it soon wore off. These things really DO whiten your teeth! My teeth tend to be slightly yellow, and that is the type of discoloration that responds best to whitening gels. I had to have a piece made for a front tooth that I chipped when I was six, so my dentist had me whiten my teeth before having the piece matched - he had to use the whitest shade of porcelain to match my teeth after I whitened them. So yeah, this stuff works. And at least in my case, the sensitivity was temporary. I'm giving this product 5 stars because I know from past use that it works, the batch I received has two years before it expires, and it's hella cheap compared to the outrageous price my dentist charged me!

## Questions & Answers

**Q: what are the correct instructions for use ....mine came without instruction leaflet**
A: According to their website:
-Brush teeth
-make continuous bead of gel using 1/3-1/2 a syringe for each tray
-insert trays over your teeth
-lightly brush away excess gel from gumline
-leave trays in for 2-4 hrs for 20%
-remove trays
-clean trays with toothbrush and water

**Q: As noted above there is an expiration date on the syringe. What is the expiration date on yours?**
A: The exp. date is located on each syringe. The newer syringes (as of Jan. 2016) have the exp. date in a readable format on the lip of the syringe where the handle enters the body. Older syringes have the exp. date inprinted on the round body of the syringe near where the handle enters the syringe. Is is encoded with a letter (batch identifier) and 3 digits, example: S127. Last digit stands for a year of expiration and the two digits after the letter is the exp. month. In the example provided the exp. date is December of 2017. NOTE: It is not 2007 as many think, the gel can not last 9 years in a syringe, it will be all dried out. Our (Green Dot Sales) current exp. date as of Feb. 2016 is 12-2017. However, the exp. date changes month to month as we update our stock on weekly basis.Thank you.

**Q: Does the product come with an expiration date that you can read so you can tell whether it is still full strength or not?

### ⭐⭐⭐⭐⭐ Opalescence PF 20%
*by L***L on February 15, 2014*

It's good, but the stronger formula works faster. However, I've also burned my gums in the past, turned white! So went back to the slower way lesser %. Be VERY CERTAIN that it doesn't get applied too heavily or it will squish out ONTO your gums. You'll feel it. Gums turn white. Use a Q-tip swab in water to get if off. I've also remove the trays, clean the overage on gums (carefully) don't want to remove from teeth however, then do the tray cleaning where it's oozed out. Only that part. Reinsert and leave them in. I normally do it before bed and sleep with them in. I always get compliments that I have a nice smile and WHITE teeth, especially the day after using it for touch up. I'm in early 60's doing it for last 3 yrs. They aren't knock out white but certainly much whiter than most people my age. I ALWAYS notice other people's teeth and think, IF ONLY they had the $ to do this how much better they would look... Sadly, many don't even notice their smile in the mirror. It takes years off of you. Oh, I've been in divorce court for 4 yrs. :D pearly whites smiling!
