Teeth Stains 101: Understanding the Types, Causes, and Prevention

Teeth stains are areas of discoloration on the surface of the teeth that can affect the appearance of one’s smile. The discoloration varies in color and severity. The stains on teeth occur due to different underlying causes. 

Understanding the root causes can help dentists treat stains appropriately and advise the best preventative dentistry. Adopting healthy oral health habits and maintaining good oral hygiene is vital to preventing tooth stains.


Teeth Stains: Causes

The most common causes are:

  • Extrinsic factors: extrinsic stains are caused by external factors leading to teeth stains

  Poor oral hygiene habits

  Acidic or sugary foods


  • Intrinsic factors: intrinsic stains occur within the tooth structure beneath the enamel.


  Dental trauma

  Excessive fluoride

  Some medications


  • Combined factors: a combination of extrinsic and intrinsic factors leads to more stubborn stains called combined stains, which are challenging to treat. For instance, staining due to tobacco combines extrinsic staining from the chemicals in tobacco with intrinsic staining from the long-term effects of tobacco use.

Teeth Stains: Types

Extrinsic, intrinsic, and combined stains appear on the teeth in shades of yellow, brown, gray, streaks of white, and so on.

Extrinsic Stains

External factors causing extrinsic teeth stains include acidic and potent pigmented foods (dark berries, beets, and curry) and beverages that come in contact with teeth upon eating and drinking.

  • Acidic beverages – tea, coffee, and wine pigments attach to enamel to cause yellow or brown stains.
  • Tobacco – causes yellow or brown stains.

Intrinsic Stains

Stains within the tooth structure, beneath the enamel are more complex to remove and may require professional dental treatments involving advanced dental technology. Common causes of intrinsic stains are:

  • Genetics – governs many traits, including the natural color of teeth and susceptibility to staining.
  • Dental trauma – internal bleeding may lead to gray or brown stains
  • Excessive fluoride causes dental fluorosis, which appears as white specks or streaks (enamel discoloration).
  • Tetracycline antibiotics – when taken during childhood, cause permanent discoloration of adult teeth to yellow, brown, or gray.
  • Aging – wearing of tooth enamel exposes more yellow dentin.

Combined Stains

Stains that occur as a combination of extrinsic and intrinsic factors will be difficult to remove and appear as.

  • White spots
  • Yellow stains
  • Brown stains
  • Gray or Black stains
  • Blue or Green stains

Poor Oral Hygiene, Acid Erosion, Excessive Fluoride: White spots on teeth are a form of staining mainly related to demineralization or early enamel decay. These spots may result from poor oral hygiene, too much acid causing enamel erosion, or excessive fluoride exposure, which damages the tooth enamel.

Aging, Tobacco, Other Beverages: The most common teeth stains are yellow stains, which result from multiple causes such as aging affecting the quality of teeth, too much tobacco use, and consumption of staining beverages. Brown stains are associated with combined tobacco use and pigmented food and beverages.

Dental Trauma, Tetracycline Antibiotics: Gray or brown stains result from dental trauma, which worsens with the use of certain medications like tetracycline antibiotics.

Antipsychotic Medications, Underlying Medical Conditions: The least common – blue or green stains are associated with medical conditions and specific medications. For example, antipsychotic medications can cause blue or green staining of teeth.



Teeth Stains: Prevention

Lifestyle changes that ensure good oral hygiene are the best preventative measures.

  • Two best practices for maintaining good oral hygiene.

  Brush daily.

  Floss regularly.

  • Rinse after eating or drinking.
  • Use a straw for drinking to limit contact with teeth.
  • Limit the consumption of stain-causing foods and drinks.
  • Quit smoking and tobacco use.
  • Protect teeth from trauma.
  • Stay hydrated.

Other measures that help prevent teeth staining include using whitening products, caution while using home remedies, good toothpaste, and ensuring regular dental checkups.
