Stained and discolored teeth affect millions of people, often leading to poor self-esteem and decreased quality of life. Dull, yellow teeth are among the most common dental complaints, but there are numerous protocols and products available to enhance their appearance.
Understanding Teeth Discoloration
The Anatomy of Teeth
Teeth are composed of multiple layers, each serving a specific function:
- Émail: La couche externe dure qui protège la dent de la carie et des dommages.
- Dentine : La couche sous l’émail, moins dure et contenant des tubules microscopiques.
- Pulpe: Partie la plus interne de la dent, contenant les nerfs et les vaisseaux sanguins.
Types of Teeth Stains
Teeth discoloration can occur on the surface of the tooth enamel or deeper within the dentin. The types of stains include intrinsic stains, extrinsic stains, and age-related stains.
Intrinsic Teeth Stains
Intrinsic stains occur inside the tooth, beneath the enamel. They are often caused by:
- Excessive Fluoride Exposure: Especially in children.
- Tetracycline Antibiotics: Use during the 2nd and 3rd trimesters of pregnancy or during early childhood.
- Dental Trauma: Damage to the tooth that affects the dentin.
- Certain Diseases: Such as dentinogenesis imperfecta.
Extrinsic Teeth Stains
Extrinsic stains occur on the exterior of the tooth, on the enamel surface. Common causes include:
- Food and Drinks: Coffee, tea, red wine, dark berries, and balsamic vinegar.
- Tobacco Products: Smoking or chewing tobacco.
- Poor Oral Hygiene: Inadequate brushing and flossing.
Age-Related Teeth Stains
Age-related discoloration is a combination of intrinsic and extrinsic stains. Over time, the dentin naturally darkens, and the enamel becomes thinner, allowing the yellow dentin to show through.
Causes of Teeth Stains
Understanding the causes of teeth stains can help in prevention and treatment. Common causes include:
Foods and Beverages
Certain foods and drinks can stain teeth due to their color and acidity. These include:
- Coffee and Tea: Contain tannins that cause staining.
- Red Wine: High in chromogens that adhere to enamel.
- Berries: Blueberries, blackberries, and cherries can leave dark stains.
- Tomato Sauce and Balsamic Vinegar: Highly pigmented and acidic.
Tobacco Products
Nicotine and tar from tobacco products can cause yellow or brown stains on teeth. Chronic use can lead to deep staining that is difficult to remove.
Médicaments
Certain medications can cause tooth discoloration, including:
- Antibiotiques : Tetracycline and doxycycline.
- Antihistamines: Like Benadryl.
- Antipsychotic Drugs: Such as chlorpromazine.
- High Blood Pressure Medications: Including ACE inhibitors and beta-blockers.
Mauvaise hygiène bucco-dentaire
Inadequate brushing and flossing allow plaque and tartar to build up, leading to discoloration.
Fluoride
Excessive fluoride, particularly during the formative years of teeth, can cause dental fluorosis, leading to white or brown spots on teeth.
Vieillissement
As enamel wears down over time, the yellowish dentin underneath becomes more visible, leading to a yellowed appearance.
Signs and Symptoms of Discolored Teeth
Recognizing the signs of discolored teeth can prompt timely treatment:
- Yellowing: Gradual change in tooth color to yellow.
- Brown Spots: Spots on the enamel surface.
- White Streaks: Often a sign of fluorosis.
- Grey Tint: May indicate deeper issues, such as dentin damage.
- Uneven Color: Variations in color across teeth.
Home Remedies for Discolored Teeth
While professional treatment is often necessary, several home remedies can help manage and reduce teeth stains:
Baking Soda and Hydrogen Peroxide
Mixing baking soda with hydrogen peroxide creates a paste that can help remove stains. Brush with this mixture once a week.
Coconut Oil Pulling
Swishing coconut oil in the mouth for 15-20 minutes can help reduce plaque and bacteria, leading to whiter teeth.
Vinaigre de cidre de pomme
Rinsing with diluted apple cider vinegar can help remove stains. However, it should be used sparingly to avoid enamel erosion.
Charbon activé
Brushing with activated charcoal can help absorb and remove stains. Use 2-3 times a week for best results.
Options de traitement professionnel
Consulting a dental professional is essential for diagnosing and treating discolored teeth. Treatments include:
In-Office Whitening
Dentists use high-concentration peroxide gels, often activated by laser light, to whiten teeth in one or two sessions.
Dentist-Dispensed At-Home Bleaching Kits
Custom-fitted trays and professional-grade bleaching gels are provided by dentists for home use.
Veneers and Crowns
Porcelain veneers and crowns cover discolored teeth, providing a permanent solution to severe discoloration.
Collage dentaire
A tooth-colored resin is applied and hardened with a special light to cover discoloration and restore the tooth’s appearance.
Over-the-Counter Whitening Products
Various OTC products can help reduce minor stains:
- Whitening Toothpaste: Contains mild abrasives and peroxide.
- Whitening Strips: Thin, flexible plastic strips coated with a peroxide-based whitening gel.
- Whitening Rinses: Peroxide-based mouthwashes.
Natural Treatments for Teeth Discoloration
Natural remedies can be effective for maintaining white teeth and improving oral health:

Swish coconut oil in your mouth for 15-20 minutes daily. This method can help reduce plaque and bacteria.
Bicarbonate de soude
Brush with a paste made of baking soda and water once a week to remove surface stains.
Vinaigre de cidre de pomme
Use diluted apple cider vinegar as a mouthwash. Rinse thoroughly afterward to prevent enamel damage.
Charbon activé
Brush with activated charcoal 2-3 times a week to absorb and remove stains.
Preventing Teeth Stains

Conclusion
Discolored teeth can impact self-esteem and overall quality of life. While home remedies and OTC products can help manage minor stains, professional treatment is often necessary for more severe discoloration. Maintaining good oral hygiene, avoiding staining foods and drinks, and regular dental visits are essential for preventing and treating discolored teeth. Consult with a dental professional to determine the best treatment plan for your needs and achieve a brighter, more confident smile.
