It is effective but it takes long time to show result, not so much effective and its bit costly. Thanks nykaa for prompt delivery

Does what it claims. I noticed a difference in its first use. Definetly recommend.

Makes teeth strong and results in teeth whitening.

it's a effective product i noticed it in a one go so recommended it.

Nice product..

it is good for teeth whitening, those who have gum problem it is useful for them also This is my 3rd purchase.

I can see my teeth getting whiter day by day. It gives shining effect in just a wash but doesn't clean the plaques totally.

It takes a while to get all the stain removed.

Wasn’t very impressed, not sure if it really works.

This powder is okay. Not found is very useful. Didn't notice any visible change. I won't there is no change but expected more from it.

Didn’t really see any change but it’s ok and in a way it does clean the teeth.

As u should only use it once or twice a week..not more than that..i used it very few times. Because it's harsh for ur gums. Also whenever i used it i didn't feel any difference.

After using this product my teeth are panning and it's all messy while use. The black powder doesn't go easily you have to wash every corner of your teeth and washroom after using it.

I tried the produ many times, but there is no difference. I wouldn't buy it again ever.

Its not clean or whitening your teeth in fact dose black your teeth your gums also get black.

I wouldn't say its very good but yes it doe it's the job on a scale of 1 to 10, I would give a 7.

Used it for 15-20 days didn’t get any results.

Home remedies work better than this.
