What Causes Teeth Discoloration?
Teeth discoloration can be caused by both external and internal factors. External factors are those that affect the outer layer of the tooth, called the enamel. These include:
- Food and drinks: Certain foods and drinks can stain the enamel over time, especially those that are acidic, sugary, or dark-colored. Examples are coffee, tea, wine, soda, citrus fruits, berries, candy, etc.
- Smoking and tobacco: Smoking cigarettes or chewing tobacco can cause yellow or brown stains on the enamel due to the nicotine and tar content.
- Poor oral hygiene: Not brushing and flossing regularly can lead to plaque and tartar buildup on the teeth, which can make them look dull and discolored.
- Aging: As you age, your enamel naturally wears down and becomes thinner, exposing the underlying layer of the tooth, called the dentin. The dentin is naturally yellowish in color and can make your teeth look darker.
Internal factors are those that affect the dentin or the pulp of the tooth. These include:
- Medications: Some medications can cause intrinsic stains on the teeth, especially if taken during childhood when the teeth are still developing. Examples are tetracycline antibiotics, antihistamines, antipsychotics, etc.
- Fluorosis: Fluorosis is a condition that occurs when too much fluoride is ingested during childhood. It can cause white spots or brown streaks on the enamel.
- Trauma: Trauma to the tooth can damage the nerve or blood vessels inside the pulp, causing it to die or become infected. This can result in a gray or black discoloration of the tooth.
- Genetic conditions: Some genetic conditions can affect the development or structure of the teeth, causing them to be discolored or malformed. Examples are amelogenesis imperfecta, dentinogenesis imperfecta, etc.

FAQ About Teeth Whitening
Here are some common questions and answers about teeth whitening that you may find helpful.
Is Teeth Whitening Safe?
Teeth whitening is generally safe if you follow the instructions and precautions of the product or method you use. However, there are some risks and side effects associated with teeth whitening that you should be aware of. These include:
- Tooth sensitivity: This is a common side effect of teeth whitening that occurs when the peroxide penetrates the enamel and exposes the nerve endings in the dentin. It can cause pain or discomfort when you eat or drink hot, cold, sweet, or sour foods or drinks. Tooth sensitivity usually goes away within a few days after the treatment, but it can last longer in some cases. You can reduce tooth sensitivity by using a lower concentration of peroxide, shorter duration of treatment, desensitizing toothpaste, fluoride rinse, or painkillers.
- Gum irritation: This is another common side effect of teeth whitening that occurs when the peroxide comes in contact with the gums. It can cause redness, swelling, burning, or bleeding of the gums. Gum irritation usually goes away within a few days after the treatment, but it can last longer in some cases. You can reduce gum irritation by using a lower concentration of peroxide, shorter duration of treatment, applying petroleum jelly or gel to your gums, or rinsing your mouth with water or saltwater.
- Enamel or dentin damage: This is a rare but serious side effect of teeth whitening that occurs when the peroxide erodes or weakens the enamel or dentin. It can cause permanent tooth sensitivity, discoloration, decay, or fracture. Enamel or dentin damage can be prevented by using a safe concentration of peroxide, avoiding overuse or misuse of the product or method, and consulting a dentist before and after the treatment.
- Uneven or unnatural-looking results: This is a possible side effect of teeth whitening that occurs when the peroxide affects different parts of the teeth differently. It can cause patchy, streaky, or blotchy results, or make your teeth look too white or gray. Uneven or unnatural-looking results can be avoided by choosing a suitable product or method for your teeth condition, following the instructions and precautions carefully, and seeking professional advice if needed.
How Long Does Teeth Whitening Last?
The duration of teeth whitening depends on several factors, such as the type and strength of the product or method you use, the degree and type of discoloration you have, your oral hygiene habits, and your lifestyle choices. Generally, teeth whitening can last from a few months to a few years. However, it is not permanent and will fade over time due to natural aging and exposure to staining substances. You can extend the longevity of your teeth whitening by following these tips:
- Brush your teeth twice a day with a fluoride toothpaste and floss daily
- Rinse your mouth with water after eating or drinking anything that can stain your teeth
- Avoid or limit smoking and tobacco use
- Avoid or limit foods and drinks that can stain your teeth, such as coffee, tea, wine, soda, berries, etc.
- Use a whitening toothpaste, rinse, or strip occasionally to maintain your results
- Visit your dentist regularly for checkups and cleanings
- Repeat the whitening treatment as needed or recommended by your dentist
