A bright, white smile is often associated with good health and confidence. However, it’s common for teeth to become discolored or develop dark spots over time. While this may seem like a purely cosmetic concern, changes in tooth color can also indicate deeper dental issues. At Dr. Reem Hejazi’s clinic, we help patients identify the causes behind tooth discoloration and provide personalized solutions for a healthier, brighter smile.

1. External Stains (Extrinsic Discoloration)

One of the most frequent reasons for tooth discoloration is staining from external sources, such as:

• Coffee, tea, red wine, and dark-colored sodas
• Tobacco products (smoking or chewing)
• Colored foods like berries, curry, and soy sauce

These substances can leave surface stains that gradually dull the appearance of teeth, especially if oral hygiene is inconsistent.

2. Internal Stains (Intrinsic Discoloration)

Discoloration can also occur inside the tooth, often due to:

• Tooth trauma, which may cause the tooth to darken or appear gray
• Certain medications, especially tetracycline antibiotics taken during childhood
• Fluorosis, caused by excessive fluoride intake during enamel formation
• Tooth decay or infection, which can create brown or black spots

In such cases, the color change isn’t just cosmetic—it may be a sign of damage or disease.

3. Aging and Enamel Erosion

As we age, the outer layer of enamel naturally wears down, revealing the darker dentin underneath. This process can cause teeth to appear yellowish or gray. Enamel erosion can be accelerated by acidic foods, acid reflux, or aggressive brushing.

4. Poor Oral Hygiene

Neglecting proper brushing and flossing allows plaque and tartar to accumulate, leading to discoloration and potentially tooth decay. Early-stage cavities may first appear as white spots, which later turn brown or black if untreated.

At Dr. Reem Hejazi’s clinic, we offer professional evaluations to determine the cause of tooth discoloration. Depending on the diagnosis, treatments may include teeth whitening, composite fillings, or veneers for cosmetic enhancement. If decay is the cause, we provide restorative treatments to protect the tooth and prevent further damage.
