## Questions & Answers

**Q: In general, how much gel should I use? Also where do you put the gel;  the front or bottom of the tray?**
A: You want to use a thin layer of gel so that it doesn't squish out and get all over your gums.  You want to put the gel on the part of the tray that lays against your teeth.  I used a small paintbrush to apply the gel.  Often, I would paint it directly onto my teeth and then cover them with the mouth tray.

**Q: Any coffee drinkers ( I mean serious coffee drinkers) notice a difference? While still being able to drink coffee?
Thanks**
A: I bought this product about a month ago. I drink coffee everyday. My teeth had coffee stains. I was using 2 different teeth whitening toothpastes to help keep my teeth from staining any further. Since I started using this product I have noticed a big difference. I'm on my 5th syringe of whitening gel, there is a total of 5 syringes that come in the package, and am completely satisfied with the results up to this point. My teeth are truly whiter than when I started using this product. 
I definitely recommend this product.

**Q: Can you use this product with veneers or crowns?**
A: This is a 2part answer.  I have both.  Here's the difference though.  When I was in first grade I broke out my front teeth and had to get the bonding or whatever they did back then.  Then fast forward 25 years later I had them redone several times over the years and back in the early 2000's I broke them again.  I wanted to have the "brite smile" done in the dentist office where they whiten your teeth so I had to get that done first and see how white my teeth got, then they redid my front teeth to match how white they were.  After the fake ones get stained by coffee etc the whitening gel will take them back to their original bright white.  If veneers or crowns were "matched" to somewhat yellow or dingy teeth the veneers or crowns will never be able to be any whiter.  Do you know what I mean?  Mine go super white because that's what the original color was.  All this would do is make all your regular teeth white and leave the veneers the color they were made to match.  Hope this helps you.  This stuff is amazing.  My teeth are so white they're off the charts.  (-:

**Q: How many consecutive days can you use this whitening gel for? How many days should you wait before starting a new cycle?**
A: I haven't used it for more than 5 consecutive days.  No issues with sensitivity in that time.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Effective teeth whitener, finally!
*by B***C on March 9, 2018*

First I will say that this is the first serious DIY tooth whitening product I have tried. I have never noticed a difference with the various whitening toothpastes, so figured, I needed something more professional. I made my decision based on origin of product, customer reviews and price. This product is near the maximum strength ever approved by the ADA. I have a lot of fillings which is a concern. I also have a little bit of gum recession, so didn't want to use something too strong, which may cause unwanted effects or necessitate another purchase of anti-sensitivity gel. I don't know why some report this product didn't whiten their teeth. I just completed my first application, and see a significant improvement - moreso than after a teeth cleaning session I recently had at my dentist. You can tell the product is working because it foams a little bit as the hydrogen and oxygen escapes. I only used about 3/4 cc, so these 5 syringes will probably provide 20 whitening sessions, but I was careful to apply the gel only to the front of my trays. I used this gel in combination with the Whiter Smile Teeth Whitening trays, because they appear to be made in the USA and are BPA free. I will provide a separate review for them. I do not trust Chinese health products, which was a positive influence for this purchase. I cannot say whether a stronger formulation would work better for me, but I can say I think this is a good product, which works well, so I can fully recommend this whitening gel. If I experience any undesirable effects I will amend this review.

### ⭐⭐⭐⭐⭐ A great choice. :)
*by L***E on September 8, 2019*

I’ve only used this once for about 20 minutes with a blue light bc I happen to have one but I’m not new to teeth whitening. I’ve been doing it off & on for years & I can already tell this is a great product. I drink coffee daily & love teeth staining foods like blueberries. So I have to whiten regularly.I’ve had trays made from a mold of my teeth. You can find this online - they send you the mix & basic upper & lower treys to make your impression (just like they do in the dentist’s office - I used to be a dental assistant) . You send that mold back. They then make upper & lower treys of the mold & send them to u. These are the best to use bc they fit perfectly so they’re very comfortable & u don’t waste any whitening product. But I previously used a 35% carbamide gel (for which I paid more) & I can already see that this works better. Absolutely no irritation at all which is amazing bc I do brush with Sensodyne or Pronamal daily for my typically sensitive teeth. So that’s a HUGE bonus for me.Also, you will easily get 3 treatments out of each syringe. You don’t want to overload the tray bc it will just spill over into your mouth when you insert them which wastes product.I keep these in my fridge as the manufacturer suggests.You’ll be pleased with this product. I hope this review helps.

### ⭐⭐⭐ So So
*by G***K on January 13, 2014*

I used this product exactly as instructed with limited results. I then gradually increased the length of time to upwards of 2 hrs per treatment. Amazingly at 2 hrs there was barely any pain involved. At the same time, there was barely any difference in color over a shorter period of time. Let me say that my teeth are not overly stained by any means, but I found that this product does a minimal amount of surface stain removal. And being as it's only minimally surface it's understandable that the treatment programs are so drawn out. You have to stay on it. I'd say that if your teeth are shiny white with minimal surface staining this is a great product. Especially if you are prone to tooth sensitivity. The problem might be that unlike a lot of other products, this one does not adhere to your teeth so by the end of a treatment it's pretty much washed away. All in all, I think this is more of a maintenance product and less of a whitening product.
