Many people ask, what causes teeth to become stained? Understanding the factors that lead to tooth discoloration can help you prevent stains and maintain a Teeth Whitening Treatment, healthier smile. Teeth can change color due to a variety of reasons ranging from lifestyle habits to natural aging processes.

Types of Teeth Stains:

Teeth stains fall into two main categories: extrinsic and intrinsic.

• Extrinsic stains: These occur on the outer surface of the enamel and are usually caused by external substances
• Intrinsic stains: These are deeper, occurring within the tooth structure itself and are often harder to remove
• Extrinsic stains can often be treated with regular dental cleaning and whitening
• Intrinsic stains may require professional treatments like bleaching or veneers
• Some people experience a combination of both types
• Knowing the type of stain helps determine the best treatment approach

Understanding stain types is key to effective prevention and care.

Common Causes of Extrinsic Teeth Stains:

Several everyday habits contribute to surface staining on teeth.

• Consuming dark-colored foods and drinks: Coffee, tea, red wine, cola, and berries are common culprits
• Tobacco use: Smoking or chewing tobacco deposits tar and nicotine, causing yellow or brown stains
• Poor oral hygiene: Inadequate brushing and flossing allow plaque buildup, which traps stains
• Certain medications: Some mouthwashes and antibiotics like chlorhexidine can cause staining
• Environmental factors: Exposure to certain metals and chemicals can also discolor enamel
• Diet high in acidic foods: Acids can erode enamel, making teeth more susceptible to staining

Limiting these factors helps keep extrinsic stains at bay.
