The strips are so convenient and super affective. I used them before big events and try to remember to use them monthly and weekly however that usually doesn't happen. So I usually use them 3 days prior to the event street and always end up very great whitening results. I will say though sometimes when I do use them 3 nights in a row my teeth are a bit sensitive for the day following. Just be sure you do not exceed the time limits given. Leaving them on longer will definitely caused damage and major sensitivity issues...yup I've done that when I was much younger and not as bright & boy did I regret it to this day, ouch!

As a health care professional, I am always looking for products to recommend. I make it a practice to always try the product before sharing. Crest 3D White Whitestrips is a great in-home product. It is convenient.... I use it in the morning, placing the strips in before my shower and by the time I have finished my make-up 30 minutes has past. I like to use Crest 3D White Glamorous White Toothpaste before I use the whitening system. I am in my early seventies and proud to say.... '"Good-by to yellow, hello to white and youthful looking teeth."

Pricey but so extremely worth it! Everyone asks how my teeth are so white and the secret it out! This product is safe for your teeth and doesn’t oversensitive them. For a deep whitening treatment head to your local dentist, but follow up with this product to keep those coffee stains off your pearly whites!

These are my jam. My ride or die. I started whitening my teeth when I was 15 with them, well I think they were advance then, the most expensive box was how I could tell which ones. I live for these and they’ll always be my go to. I receive so many compliments on my pearly whites.

This is the best toothpaste that exists in the market, it leaves me with a great freshness in my mouth and good breath and it also whitens my teeth in a magnificent way, I used it years ago and I would not change it for anything I get it in any Pharmacy And it is High quality I recommend it for someone who like me to wear shiny white teeth, it leaves you clean and fresh that will fascinate you

I just bought this product and have only used it once so far I don’t see a difference in my teeth but I hope that with my treatments that my teeth will begin to whiten like the packaging says it does. If this works well I will buy again. And it is a bit pricey.

The best way to whiten your teeth! I get comments all the time for my white teeth and my dentist actually told me that I have a "movie star smile." You don't have to use them all the time to get results either. I used them every few days at first but now I only use them every few months. Highly recommended!

This is a great at- home teeth whitening kit. The strips stay on easily. I could see a difference after using one time. After using daily for a week my teeth were visibly whiter. I have sensitive teeth so using too much can leave them a little sensitive. But overall I would recommend this kind of teeth whitening.

I just like how easy they are to use. If you have sensitive teeth these are not for you. They meet my expectations. I wish the strips to be a bit longer on both the top and bottom. I use these about 1-2 a month. I definitely recommend to others, but be warned... they are not cheap.

I absolutely love crest whitestrips. I tend to use them more often leading up to a special event. I used them frequently leading up to my wedding and my teeth were pearly white for my bridal portraits! I also have sensitive teeth and these strips don’t irritate me or cause more sensitivity.
