About Product Choice
are whitening strips bad for your teeth?
Whitening strips can be safe for your teeth when used properly, but there are some potential downsides to consider:
- Sensitivity: The most common issue is tooth sensitivity, which can cause discomfort, especially for people who already have sensitive teeth.
- Gum irritation: Whitening strips can irritate your gums, especially if they come into contact with the gum tissue.
- Uneven whitening: If the strips don't fit your teeth perfectly, you may experience uneven whitening.
- Enamel damage: This is a concern if you overuse whitening strips or use ones with harsh chemicals like chlorine dioxide. Enamel is the protective outer layer of your teeth, and damage to it can increase your risk of cavities.
Here are some tips for using whitening strips safely:
- Follow the directions carefully. Don't use the strips for longer than recommended or more often than recommended.
- Choose strips designed for sensitive teeth. These strips typically contain a lower concentration of the whitening agent.
- Talk to your dentist before using whitening strips. They can advise you on whether they are right for you and recommend a specific brand.
If you experience any discomfort while using whitening strips, discontinue use and consult your dentist.
