Stained or Discoloured Teeth

Teeth can become darker or discoloured over time for many reasons. These may include foods and drinks, smoking, ageing, some medicines, previous dental treatment or changes within a tooth.

A dental assessment is recommended before whitening. It helps identify the likely cause of discolouration and whether whitening is appropriate for your teeth and gums.

What are the treatment options?

• Over-the-counter whitening products
 – A range of whitening toothpastes, strips and other products is available. Their use, suitability and results can vary.
• Custom-made take-home whitening trays
- Custom trays are made to fit your teeth and used with a whitening product as directed by your dentist. Treatment is completed over a period of time determined by your individual plan.
• In-chair whitening -
In-chair whitening may be considered for some patients. Your dentist can discuss how it works, what it involves and whether it is appropriate for you.
• Porcelain veneers or crowns
- Whitening products do not change the colour of existing fillings, crowns or veneers.

Where discolouration cannot be addressed with whitening alone, restorative options may be discussed following assessment. We will explain the relevant benefits, risks, costs, alternatives and expected treatment process before you decide whether to proceed.

How long does treatment take?

The timing depends on the type of whitening, the cause of discolouration and your individual circumstances. Take-home whitening is usually carried out over a period of days or weeks. In-chair whitening is completed during an appointment, though further treatment may be recommended in some cases.

Your dentist will provide an estimated treatment plan after assessment.

Is teeth whitening uncomfortable?

Tooth sensitivity and gum irritation can occur during whitening treatment. These effects vary between individuals and are often temporary. Correct use of whitening products and custom trays is important.

We will provide instructions for using any prescribed whitening product and discuss what to do if you experience sensitivity or irritation.

How long will whitening last?

The duration of a whitening result varies. It can be affected by diet, smoking, oral hygiene and the original cause of discolouration.

Some people choose to have further whitening treatment over time. Your dentist can discuss an appropriate maintenance approach for you.

How much does teeth whitening cost?

Costs depend on the whitening option selected and whether any additional dental care is required. After assessment, we can provide a written estimate for the options discussed.
