Stained teeth refer to teeth with discoloration or darkening of the enamel, which can affect their appearance. Staining can occur due to various factors:
- Extrinsic Stains: These are caused by substances that come into contact with the outer layer of the tooth enamel. Common causes include:
Food and Drinks: Coffee, tea, red wine, and colored foods can stain teeth over time.
Tobacco: Smoking or using tobacco products can result in yellow or brown stains.
Poor Oral Hygiene: Not brushing and flossing every day can allow plaque and tartar buildup, which can cause stains.
- Intrinsic Stains: These occur within the tooth structure itself and are harder to remove. Causes include:
Trauma: An injury to the tooth can discolor or darken it.
Medications: Certain medications, like tetracycline antibiotics, can cause intrinsic stains if taken during tooth development.
Excessive Fluoride: Too much fluoride exposure during childhood can lead to fluorosis, causing white or brown spots on teeth.
