Teeth Whitening
(Medical procedures and examinations)
This topic will help you learn about teeth whitening and how to prepare for it.
What is teeth whitening?
1Teeth whitening is a non-surgical procedure used to improve the color of teeth by removing surface and deep stains. This procedure relies on bleaching agents that usually contain hydrogen peroxide or carbamide peroxide, which work by breaking down stains and lightening the tooth color without affecting its structure.
- What are the types and forms of teeth whitening?
- 1. In-officeLEDteeth whitening:
- Performed under the supervision of a dentist.
- High concentrations of the bleaching agent are used, sometimes with laser or LED light, to speed up the results.
2Usually provides quick and effective results, often after one session.
- Suitable for severe discoloration.
- 2. At-home teeth whitening (under dental supervision):
Involves using custom-made trays filled with bleaching gel and worn at home for several days.
Results are gradual but safe.
- 3. Over-the-counter whitening products (without prescription):
- Whitening strips:
- Contain a bleaching agent (usually hydrogen peroxide) and are applied directly to the teeth.
Typically used once or twice daily for 30 minutes, for 1–2 weeks.
- Relatively effective for teeth with surface stains.
- Whitening toothpastes:
- Contain mild abrasive or chemical agents to remove stains.
Used daily like regular toothpaste.
- Less effective than strips, but useful for daily cleaning and preventing new stains.
- Whitening pens:
- Easy to use, applied directly to the teeth with a small brush.
Usually used once or twice daily and do not require rinsing.
Effective for temporary or quick touch-ups, but not strong enough for deep stains.
When is teeth whitening performed?
- Teeth whitening is performed when teeth show stains or discoloration. Before starting treatment, it is important to consult your dentist to ensure that teeth whitening is suitable for your condition.
- Whitening is not recommended in the following cases:
- Pregnancy or breastfeeding.
- Severe tooth sensitivity.
- Active gum disease.
Presence of cavities or cracks in teeth.
Presence of crowns, veneers, or fillings (note that whitening does not affect these restorations).
- Whitening may also be ineffective if the discoloration is due to an internal tooth problem.
- Who needs teeth whitening the most?
- Smokers, due to stains caused by tobacco on teeth.
Those who frequently drink colored beverages, such as coffee, tea, and soft drinks.
Those who do not brush their teeth regularly, leading to accumulation of stains and spots.
How is teeth whitening performed?
There are several methods for teeth whitening that vary in effectiveness and the degree of professional supervision:
1. At the dentist’s office:
A high concentration of hydrogen peroxide is used, often with a special light or laser to speed up the whitening process. Results are noticeable from the first session in many cases.
2. At home under dental supervision:
The patient is provided with custom trays containing the whitening agent at a lower concentration than those used in the clinic. Results appear gradually within about two weeks.
3. Over-the-counter products:
- Such as whitening strips, toothpastes, or mouth rinses. These help remove light stains but are less effective compared to professional methods.
- What are the possible side effects of teeth whitening?
- Temporary sensitivity: especially to hot or cold foods and drinks.
- Gum irritation: sometimes caused by contact of the whitening agent with gum tissue.
Enamel erosion: with excessive or repeated use without professional supervision.
- Uneven results: if the product is not used correctly or if there is a natural variation in tooth color.
- How to prepare for teeth whitening?
- Consult your dentist before starting treatment.
- Have your teeth cleaned to remove tartar.
Avoid foods and drinks that cause staining for 48 hours before whitening.
- Use toothpaste for sensitive teeth if you suffer from tooth sensitivity.
- How to maintain white teeth?
- Brush your teeth twice daily using fluoride toothpaste.
- Use dental floss once daily to remove food residues between teeth.
- Limit consumption of colored drinks, such as coffee, tea, and dark juices.
Avoid smoking, as it directly affects tooth color.
Visit your dentist every six months for examination and regular cleaning.
