Why I Chose Crest Whitening Strips Level 18
I was looking for a product that offered noticeable whitening without the hassle of professional treatments. Crest Level 18 strips promised to remove tough stains and deliver results in about two weeks, which sounded perfect for my busy lifestyle.
Understanding the ‘Level 18’ Whitening Strength
The “Level 18” refers to the strength of the whitening formula.

Each box comes with 14 treatments, enough for one treatment every day for two weeks. I found it easy to apply the thin, flexible strips directly to my teeth. Wearing them for 30 minutes daily fit well into my routine, and the strips stayed in place without much discomfort.
My Tips for Best Results
- Make sure your teeth are dry before applying the strips for better adhesion.
- Avoid eating or drinking while wearing the strips.
- After finishing the two-week course, maintain your smile by limiting stain-causing foods and drinks.
Potential Sensitivity and How I Managed It
I did notice mild tooth sensitivity after a few days, which was expected with stronger whitening products. To manage this, I used a toothpaste for sensitive teeth and took short breaks if needed. This helped me complete the treatment comfortably.
Who Should Consider Crest Level 18 Whitening Strips?
If you want a strong, at-home whitening solution and are okay with some temporary sensitivity, these strips are a great option. However, if you have very sensitive teeth or dental restorations, I recommend consulting your dentist first.
