Crest 3D White Gentle Routine Teeth Whitening Strips Review

Luckily there are whitening strips on the market with a lower concentration of hydrogen peroxide that offer a much gentler, comfortable whitening experience. One of those on the market are ​Crest 3D White Gentle Routine Teeth Whitening Strips​. In this article I'll be reviewing these white strips so you can decide for yourself if they are right for you.

  • PEG-8
  • Acrylates Copolymer
  • Hydrogen Peroxide
  • Sodium Hydroxide
  • Sodium Saccharin

Sensitive Teeth

Peroxide, when used as a teeth bleaching agent deeply penetrates the enamel to reach stains and because of this causes sensitivity in many people.

Crest 3D Gentle Routine White Strips were formulated specially for patients who are sensitive to the active whitening ingredient - peroxide. Gentle routine white strips are less concentrated in peroxide than regular white strips. They can still cause some sensitivity in some patients, but it shouldn't be as noticeable as with the higher peroxide concentration strips. It would be wise to speak to your dentist before choosing a teeth whitening option to get the best advice.

Some patients worry that because they feel this pain/discomfort that the whitening strips are harming the enamel of their teeth. This 2007 study should put your mind at rest as it revealed no deleterious effects on the enamel surfaces when examining the effects of hydrogen peroxide whitening strips.

Treatment Period

Included in the package are 28 whitening strips to be used over a period of 14 days. Each day you will use one strip for the lower teeth and one for the upper teeth. Some people get confused over which strip is for upper and which is for lower. It depends on each package but in this case the lower strip is noticeably shorter. The strips should be applied for 30 minutes per day over the 2 week period.

How to Use Crest Gentle Routine White Strips

  • Peel the upper strip from the liner
  • Align it with the gumline of your top teeth
  • The gel side should be touching the teeth
  • Press gently for good contact
  • Fold the rest of the strip behind teeth
  • Repeat for bottom set of teeth
  • Leave on for 30 minutes
  • Peel off and discard
  • Repeat daily until the box is finished (14 day treatment)

The Results

Crest Gentle Routine white strips are said to gently remove years of stains. Being that the concentration of hydrogen peroxide is lower for sensitive teeth patients, it may take longer for results to be seen, but should be noticeable after the 2 week period when instructions are followed properly. Keep in mind that at-home teeth whitening kits do not work for everyone. If you are one of the lucky ones then at-home teeth whitening kits are a great option!


If you are not happy with the results, Crest white strips are 'Satisfaction Guaranteed'. So you can return your receipt and the package UPC within 60 days of purchase for a prepaid card in the purchase amount.

The Verdict

Whitening teeth at home is a simple and affordable solution to whitening at the dental office. Many people have had success with Crest 3D Gentle Routine Whitening Strips. I know some people may be afraid to try them at first due to the discomfort they would normally feel from regular strips, but after giving these strips a try you may find that there is no need to give up on trying to whiten your teeth at home. For an added whitening boost, you can even brush with a whitening toothpaste.
