1. What are whitening toothpastes?
They are specially formulated toothpastes designed to lighten the color of teeth and remove stains caused by coffee, tea, smoking, or certain colored foods. These toothpastes do not change the internal color of the teeth but reduce the yellowing that appears on the surface.
2. How do they work?
- Gentle abrasives: Help remove plaque and surface stains.
- Whitening chemical ingredients such as hydrogen peroxide or sodium carbonate, which break down stain-causing particles.
- Polishing agents: Give teeth a brighter, shinier appearance after cleaning.
3. Usage guidelines
- Use whitening toothpaste twice daily like regular toothpaste, but it’s best not to overuse it to avoid enamel erosion.
- It is recommended to alternate with a gentle, fluoride-containing anti-cavity toothpaste.
- Brushing time should not exceed two minutes using a soft-bristled brush.
- Consult a dentist if there is sensitivity or gum problems.
- Results usually take weeks of regular use to become noticeable.
4. Important notes
- These toothpastes are only suitable for external stains and do not change the natural internal color of the teeth.
- They are not a substitute for professional whitening sessions at the dentist, but they are a safe way to improve the daily appearance of your smile.
