I have sensitive teeth and did not experience any pain or sensitivity with this like I did with traditional whitening bleach from the dentist. However, those were my personal results and everyone experiences different results. Try it and if it doesn't work for you, return it to Sephora within 30 days of receipt and they will give you a full refund.

If you purchased this at Sephora or at Sephora.com, yes, you can return it and get your money back in full. Even if you have used it and then decided you didn't like the product. Sephora stands by their products and if you are unhappy with them, you are absolutely able to return the product with a full refund.

Hello,

This will definitely work on teeth that are natural white. You will notice a difference in the first few applications.

It does. I do not think that it will make every person's teeth look like chicklets gum, but I think it will make them significantly lighter at an overall fraction of the cost of some products bought professionally. As I said previously, if it ends up disappointing, keep the receipt and bring in all the parts to your local Sephora, explaining what did not work. They truly believe in their products, as do I, and have a very helpful and supportive staff.

It is designed to whiten teeth as much as professionally whitening at a dentist. If that doesn't normally work, then no unfortunately. It will lighten venires up tO their original shade. But not lighter than when they were put in.

I'm not a dentist, so I can't say what is causing your teeth to look dingy or yellow - I am a redhead with pale skin, so no matter how much I whiten my teeth, they always look a little bit yellowish - it's just the way my teeth look against my skin and hair...I find that this product makes me teeth look clean, and they have a nice...shine, not sure if that's the right word, but glow to them - they'll never be movie star white, but they look healthy and clean and not dull.
Not sure if that's enough to justify $300+, but there you go.

GLO Brilliant can not change the color of unnatural teeth but It can take away surface stains that build up bringing the unnatural tooth back to the color that was originally put in.
GLO also has a Whitening Antioxidant toothpaste and Whitening Maintenance pen that can help keep the teeth white and remove stains before they set.
Perfect products for anyone that has veneers, crowns and bonding.

The most it will do it restore them to their original colour. No whiter. So it can remove stains and all but if your caps have been matched to your teeth colour at the time, they will stay that way.

I've been a dental hygienist for 24 yrs. and there isn't ANY whitening product that will change the color of dental work already in the mouth. If there is an obvious difference in color after you whiten you would have to change the filling or crown/cap to match the whiter shade. I'm not sure if there is any product that can claim no sensitivity, there is always a chance when you use whitening products.

No, we do not recommend sharing mouth pieces due to clean oral hygiene. Each mouth piece is sold separately. http://www.sephora.com/glo-brilliant-mouthpiece-case-P281837

I would highly recommend getting a separate one, as they tend to form to your personal mouth shape and would make it awkward for the other user. Going back to you using it again, it might not fit you as well , either. It's a litlte pricey, but the person could use it indefinitely just as you will be able to!

If the discoloration occurred after the root canal, then your best bet is to have internal bleaching done. If your tooth is strong enough, you may not even need a crown, and if you have a crown placed and the discoloration is internal, you will still see the discoloration through the crown.

This product only works on whitening the external enamel of your tooth. If your tooth is dead then any discoloration would be emanating from the inside of your tooth so this product won't help you. If you have some discoloration of your enamel then it will whiten that but won't fix internal decay problems.

The best thing to do for a dead tooth is have it removed and have a dental crown done on it to replace it. You want that thing out of your mouth. You'll want to whiten your teeth to the whitest shade you can get them and then have your crown done to match the color of your teeth. Then you will have to be diligent about keeping up on your teeth whitening regimen in order to prevent the rest of your teeth looking more yellow than your crown. A crown or veneers do not respond to whitening products because they are non porous.
If you have dental coverage, it should pay for a good portion of the crown you need. Good luck!

Are you sure there is NO change? I took pictures to monitor my change. Are you putting enough of the liquid on your teeth beforehand? Monitor how long it takes you to go through one vial of the liquid lightener. If you are far from one with one after four sessions, you are not using enough. It's slightly difficult to monitor that at first. I recommend checking that out at first. After the uses (four daily) back to back? I think that helps, too. Your teeth should be clean ahead of time before using it each day.. All of these reasons might contribute to why it is not working as well as it should. If not, I might take it in but talk to a consultant that is knowledgable about the GLO before returning it.

They recommend your first treatment be for 10 days. To boost effect, try using a whitening toothpaste and mouth rinse such as Crest 3D White at least once per day. I saw results within 3 days. It's harder to notice on yourself. The best thing to do is ask a friend or a coworker after the 10 days are up (you can use for 14 days straight) if they notice your smile being brighter and whiter. The important thing to remember is that you aren't going to go from 0-60 in 10 seconds. I recommend your first treatment being 14 days and then about 10 days later, use it for another 4 days in a row and if your friends, family, whoever do not notice a difference, you still have time to return it to Sephora for a full refund.

Hi - I can help with this one. The teeth wont dry out from the Glo system. The directions are to dry your teeth a bit before applying the whitening gel-it makes the application even better. As for the saliva-you can swallow while whitening for the 8 minutes. When the 8 mins are up you spit the excess saliva out. and just do that again 3 more times in a row. It makes sense that you build up saliva. :-) hope that helps you. :-)

It doesn't dry your teeth, before you use it you need to dry your teeth by wiping off any saliva (I use a tissue or paper towel). This enables the product to 'stick' to the white of your tooth better. I do get a bit of saliva action happening as well, but less if I dry my teeth before the first use.

I have had one as well and so far, it is truly whitening my teeth. If you keep your receipt and after a few treatments you do not see any change, you can always return it. Sephora is more than understanding if their products do not work, as they believe in the products they sell and use them themselves. Just make sure you keep all the parts and fill the box back with all the parts you have.

I have seen people mislead to believe that this system will "perhaps whiten teeth that are gray from tetracycline" etc. If your dentist can't do it, this certainly can't do it and they should be honest with you rather than encouraging people to try anyway.
