My Buying Guide on ‘Crest Level 18 Whitening Strips’

Welcome to my buying guide for Crest Level 18 Whitening Strips! As someone who has tried multiple teeth whitening products, I can confidently say that these strips are one of the best options out there. In this guide, I will share my personal experience and provide all the necessary information you need before making a purchase.

What are Crest Level 18 Whitening Strips?

Crest Level 18 Whitening Strips are a popular at-home teeth whitening product. They come in a pack of 28 strips (14 upper and 14 lower) and are designed to be used for 30 minutes daily for two weeks. These strips use advanced seal technology to adhere to your teeth and remove years of tough stains, giving you visibly whiter teeth.

Why choose Crest Level 18 Whitening Strips?

I have tried various teeth whitening methods such as toothpaste, mouthwashes, and other whitening strips, but none of them have given me the same results as Crest Level 18. Here’s why I highly recommend these strips:

  • Effective: These strips contain hydrogen peroxide, which is the main ingredient in most professional teeth whitening treatments. This makes them highly effective in removing tough stains and giving you noticeably whiter teeth.
  • Convenient: The strips are thin and flexible, making them comfortable to wear for the recommended time of 30 minutes. You can easily go about your daily tasks while wearing them without any discomfort.
  • No mess: Unlike other whitening methods that require trays or messy gels, these strips are mess-free. You simply peel off the strip from its backing and apply it directly onto your teeth.

How to use Crest Level 18 Whitening Strips?

The process is simple and straightforward:

  1. Open the foil pouch and take out one strip.
  2. Gently peel off the strip from its backing.
  3. Apply the gel side of the strip onto your top or bottom teeth (depending on which strip you’re using) and align it with your gumline.
  4. Fold any excess strip behind your teeth for a secure fit.
  5. Repeat for the other set of teeth.
  6. After 30 minutes, remove the strips and discard them. Do not rinse your mouth or brush your teeth immediately after using the strips.

Tips for best results

To get optimal results from Crest Level 18 Whitening Strips, here are some tips based on my personal experience:

  • Avoid eating or drinking dark-colored foods/drinks: During the two-week treatment period, try to avoid consuming foods or drinks that can stain your teeth such as coffee, red wine, berries etc. This will help maintain the whiteness achieved by using these strips.
  • Floss before using strips: Make sure to floss before using these strips as they may not be able to reach in between tight spaces between your teeth if they are covered with plaque or food particles.
  • Patiently follow instructions:The instructions state that you should use these strips daily for two weeks without skipping any day for best results. Make sure to follow this routine diligently even if you don’t see immediate results after a few days. Patience is key!

In conclusion

If you’re looking for an effective and convenient way to whiten your teeth at home, I highly recommend trying out Crest Level 18 Whitening Strips. With proper usage and following recommended tips, you can achieve significantly whiter teeth in just two weeks! So go ahead and give them a try!
