About the treatment

Yellow teeth are a common concern that can affect confidence and overall appearance. While some yellowing occurs naturally with age, staining from food, drinks, smoking, and poor oral hygiene can make teeth appear dull and discoloured.
Although yellow teeth may not always indicate a dental problem, stains and plaque buildup can increase the risk of cavities and gum disease. Fortunately, professional teeth whitening treatments and preventive care can help restore a brighter, healthier smile.

What Causes Yellow Teeth?

Several factors contribute to tooth discolouration, including:

  • Food & Drinks – Coffee, tea, red wine, soft drinks, and dark berries can stain enamel.
  • Tobacco Use – Smoking and chewing tobacco lead to deep, stubborn stains.
  • Poor Oral Hygiene – Plaque and tartar buildup cause discolouration.
  • Aging – The outer enamel layer naturally thins, revealing the yellow dentin beneath.
  • Genetics – Some people naturally have darker or more yellow-toned enamel.
  • Medications & Medical Conditions – Certain antibiotics, chemotherapy, or excessive fluoride exposure can cause yellowing.
