Stained & Discoloured Teeth

Having stained/discoloured/yellow teeth is a concern for many people. It affects the look of your teeth and your overall smile. There are many reasons why you may have stained teeth. Some stains affect only the outer surface (superficial) of the tooth. Whereas, others affect the structure of the tooth, which makes treatment more challenging.

Common causes of outer (superficial) stains include:

  • - Coffee and tea
  • - Red wine
  • - Cola Drinks
  • - Plaque
  • - Mouthwash rinses
  • - Soy Sauce
  • - Tomato Based Sauces
  • - Curry


Deeper stains occur due to trauma, excess fluoride intake in children, illness or disease in children which affects the development of their teeth and other developmental conditions of teeth such as enamel hypoplasia or mottling. These appear as white, brown or yellow patches that cannot be removed by traditional stain removal methods.

Before addressing removal or treatment of stains, it is important to find the cause to prevent re-occurrence. At Siana Dental, we complete a thorough diet history and examination, to find the cause before planning treatment.

Treatment for outer superficial stains include a professional full mouth clean and polish, use of home whitening toothpastes and in chair whitening options such as ZOOM.

Deeper stains require more invasive options. Porcelain veneers and crowns are usually the only option to fix the appearance of these teeth.

Stains are not directly harmful for teeth. However, outer stains make the surface of the teeth rough. This attracts more plaque to the teeth and thereby increasing the risk of decay and gum disease. Deeper stains sometimes show up areas of the weakness in the surface of the tooth and can easily decay. If you are unsure about whether your stains are a problem or not, contact us at Siana Dental and we will be able to guide you.
