There are several methods for whitening teeth. You can buy whitening products for daily use at a pharmacy or follow your dentist’s instructions. The products contain hydrogen peroxide or carbamide peroxide. Because these products break down, oxygen enters the tooth enamel, rinsing them out. Dentists can also use lasers to achieve this result.
As you age and according to human nature itself, your teeth begin to darken. Often, this process occurs more quickly for different reasons:
- When drinking beverages such as tea, coffee, red wine or other foods with a high coloring content.
- Another important cause is smoking, which can make your teeth look yellowish.
- Tooth decay, fillings and tartar can contribute significantly to discoloration.
- If the nerves and blood vessels of the teeth are damaged by decay or a blow, they can also become darkened.
- Some types of stains can be caused by diseases or medications. For example, if a type of antibiotic called tetracycline is given to children whose teeth are still developing, their teeth will probably look yellowish or greenish as adults.
Alternatives to teeth whitening
Means we can use to improve the appearance of discolored teeth include：
- Check and confirm the healthy appearance of your teeth by removing tartar build-up.
- Follow tips on tooth decay prevention.
- Brush your teeth regularly.
- Do not smoke or, if you have this habit, quit.
- Reduce the consumption of beverages and foods with high levels of colorants so that stains do not appear, or continue to appear, on your teeth.
Whitening toothpastes are somewhat abrasive. They can help remove superficial stains but do not alter the shade of your teeth. Experts are currently reviewing the effectiveness of these toothpastes. Your dentist can advise you about replacing metal fillings or crowns with others that are the natural color of your teeth.
Tooth Whitening Tips
Your dentist can advise you about the various types of teeth whitening and which one may be most effective for you. For example, the current color of your teeth may interfere with home whitening or photoactivation whitening. It is also necessary to assess the colour of your skin in order to make the result of the treatment appear as natural as possible.
Products used at home may not be suitable if the nerves responsible for innervation of the teeth are damaged and could cause discoloration. You may need stronger products that should only be used by professionals.
It is important to remember that if you have fillings or materials attached to your teeth, they will not bleach and will be a different color, so in this case the veneers may be more effective.
