What could cause brown spots on teeth

Brown marks or stains on teeth can be attributed to various factors. It's important to identify the cause to determine the appropriate treatment. Here are some common reasons for brown marks on teeth:

1. Food and Drink Stains:

- Certain foods and beverages, like coffee, tea, colas, wine, and some fruits and vegetables (such as apples and potatoes), can cause brown stains on teeth due to their strong color pigments, called chromogens.

2. Tobacco Use:

- Smoking or using chewing tobacco can result in brownish or yellowish tooth stains.

3. Poor Oral Hygiene:

- Inadequate brushing and flossing can lead to the buildup of plaque and tartar, which can cause teeth to appear brown.

4. Dental Decay:

- Tooth decay and cavities can cause brown spots on teeth as the enamel breaks down and bacterial activity increases.

5. Fluorosis:

- Excessive fluoride exposure, especially during teeth development in children, can lead to a condition called fluorosis. It typically appears as white streaks or spots, but in more severe cases, it can turn into brown stains.

6. Tetracycline Stains:

- Use of the antibiotic tetracycline during childhood or by a mother during the second half of pregnancy can cause brown or gray stains on a child’s developing teeth.

7. Trauma:

- Injury to a tooth, particularly during childhood when teeth are still developing, can disrupt enamel formation and lead to discolouration.

8. Certain Mouthwashes:

- Some mouthwashes containing chlorhexidine and cetylpyridinium chloride can cause brown stains with prolonged use.

9. Genetic Disorders:

- Certain genetic conditions can affect tooth enamel and dentin, leading to discolouration.

10. Aging:

- As you age, enamel naturally wears down, revealing the darker dentin underneath and making teeth appear more yellow or brown.

If you notice brown marks on your teeth, it's advisable to consult a dentist for a proper diagnosis and treatment. The dentist can determine the cause of the discoloration and recommend appropriate measures, which might include professional cleaning, whitening treatments, addressing cavities, or changing certain lifestyle habits.
