My Buying Guides on Crest Whitening Strips Level 18
When I first decided to brighten my smile, I came across the Crest Whitening Strips Level 18. After using them and doing some research, I want to share my insights to help you decide if they’re right for you.
What Are Crest Whitening Strips Level 18?
These strips are a teeth whitening product designed to remove stains and lighten your teeth by up to 18 shades. They use a peroxide-based formula that targets deep stains caused by coffee, wine, or smoking. From my experience, they offer a noticeable difference without the need for expensive dental treatments.
How Do They Work?
I found that the strips are coated with a gel containing hydrogen peroxide. When applied to your teeth, this gel penetrates the enamel to break down stains. The Level 18 indicates the strength and whitening power, which is stronger than the lower-level strips but still safe for regular use.
My Experience With Application
Applying the strips was straightforward. They come with a flexible backing that molds easily to your teeth. I wore them for about 30 minutes daily, as recommended. The strips stayed in place well, and I could even talk lightly while wearing them. Just make sure your teeth are dry before applying for the best adhesion.
Effectiveness and Results
After about two weeks, I noticed my teeth were visibly whiter. The “Level 18” claim felt accurate because my teeth lightened significantly but without sensitivity issues I’ve had with other stronger products. Results may vary, but consistency is key.
Considerations Before Buying
- Sensitivity: If you have sensitive teeth, start with shorter wear times to see how your teeth react. I experienced mild sensitivity initially, which subsided quickly.
- Cost: These strips are moderately priced compared to professional whitening, making them a good value if you want effective results at home.
- Usage Frequency: Follow the instructions carefully. Overuse won’t speed up results and can cause irritation.
- Lifestyle: Avoid staining foods and drinks during the treatment period for best results.
Where to Buy and What to Look For
I purchased mine online from a reputable retailer to ensure authenticity. When buying, check for:
- Sealed packaging
- Official Crest branding
- Clear expiration dates
Avoid deals that seem too good to be true, as counterfeit products can be ineffective or harmful.
Final Thoughts
For me, Crest Whitening Strips Level 18 struck a good balance between strength and comfort. If you want a brighter smile without visiting the dentist, they’re worth trying. Just be patient and follow the instructions for the best outcome.
I hope my guide helps you make an informed choice about Crest Whitening Strips Level 18!
