does it darken crowns

I have two caps and so far it has not done anything to them. Please go on the internet and see the reviews that are on there. Hope this will help you.

On the information sheet inside of the package it says to consult your dentist and that it's not intended to whiten crowns and dentures.

Test it first. If you use a lot, it will darken the leather but it seems to return to the original color in a few days.

did not noticibly darken any of the boots we used it on. One pair was a camel tan similar to original timberland boot color. After it dried couldn't tell the difference. Yes would work be sure to use a couple coats

If you are talking about the whitening aspect, I rather doubt it. I don't imagine any whitening treatment (unless at a dentist's office, maybe?) can do anything for partials--but I don't have partials so I don't know the final answer to that. I do have crowns, and crowns will forever more remain the color they are unless you replace them.

It will temporarily darken some areas of the leather. I had some medium brown boots and it darkened some areas that were more worn. I actually liked the effect as it made the leather look richer and less ashy.

It hasn't darkened anything I have used it on, but it might if you use it on a really dry porous piece. The items I have used it on were not real dry since I take care of them. I have used it on gun leather, boots, and purses so far and am totally pleased with the results. The best I have found.

Yes, although you will only see some increased gloss and maybe very fine haze/scratch removal on white. The polishing oils will deepen darker colors but have no real optical effect on white.

No it will not darken leather. I've used Bick's products for over 20 years, they are superior!

W., this absolutely, without a doubt DOES darken leather. Most any petroleum/wax leather application will darken lightly tanned leathers. However, I've had good success with Otter Wax not darkening very much.

Hi, I just have one crown, my lower molar which I have had since 2011, they have never changed its pearly white color and using this Colgate Optic White Toothbrush and Whitening Pen made it more white compared to the rest of my teeth.

I haven't found it whitens my crowns but maybe i need to try it again. I don't believe GLO says it whitens the crowns, only natural teeth.

Yes, I did. It will darken it a little, especially in a scratch. I was unable to find a light color wax.

I have crowns on my front two teeth. Both the Optic White Paste and pen have made a huge difference on both my "real" teeth and my crowns. Crowns get dirty and stained just like real teeth, this just helps remove that.

I really do not know about crowns. My "guess" would be yes. This is the ONLY product I have found that works on bonding. No other toothpaste made a difference. I would think since bonding is so difficult to keep clean and this does the trick - it would probably work on crowns. I wish I had a better answer for you, but I don't have a crown(s). Sorry!

Yes it will help. Just make sure you apply it evenlly so it won't get blotchy. And be careful with your fingernails. It has a tendency to leave some purplish color if you have light color fingernail polish. Overall it does a great job managing that golden color and turn to a more frost color.

I have not noticed the crowns I have ever changing, as my own teeth do. In other words there color seems to remain stable. Jim
