What is teeth whitening?

Teeth whitening is a method of using an oxidizing agent (usually hydrogen peroxide or carbamide peroxide) to remove yellow, dull pigments deep inside the enamel, helping teeth become 2-4 shades whiter than before. This is a simple, fast, safe and highly effective cosmetic dental procedure.

Teeth become yellow over time due to many different causes, which can be divided into two main groups: external causes and internal causes.

External causes (Exogenous)

These are factors from the environment and daily habits that cause tooth discoloration:

  • Food and drinks: Dark-colored foods such as coffee, tea, red wine, colored soft drinks, sauces (black sauce, ketchup, etc.) contain pigments that can adhere to tooth enamel, gradually discoloring teeth.
  • Smoking: Nicotine and tar in cigarettes easily adhere to the tooth surface, forming yellow stains, even dark brown over time.
  • Poor oral hygiene: Not brushing your teeth properly or not flossing causes plaque and tartar to accumulate, darkening teeth.
  • Using mouthwash containing Long-term chlorhexidine: Some mouthwashes can discolor teeth if used too often.

Internal (Endogenous) causes

These are changes that originate from within the tooth structure, and are often more difficult to correct:

  • Natural aging: Over time, the outer layer of tooth enamel gradually wears away, exposing the yellow dentin underneath, making the tooth appear darker.
  • Fluoritis: Too much exposure to fluoride during tooth development can cause white or yellow-brown spots on the teeth.
  • Tetracycline antibiotic exposure: If a pregnant woman or a child under 8 years old uses this antibiotic, the teeth may become permanently discolored, usually with gray or dark brown streaks.
  • Tooth trauma: A strong impact can cause can damage the tooth pulp, resulting in discoloration (usually the tooth turns gray or brown).
