The “white diet” is a simple aftercare guide that focuses on lighter-coloured foods and drinks for the first 48–72 hours after your teeth whitening treatment.

During this time, we recommend choosing foods such as white rice, pasta, chicken, fish and potatoes, while avoiding strongly pigmented foods and drinks such as coffee, tea and red wine. This can help minimise staining and maintain your whitening results.

We recommend waiting around 2–3 hours before eating your first meal after your teeth whitening treatment. You can drink plain water immediately.

Teeth can experience temporary dehydration following whitening, so drinking plenty of water is recommended. For the first 48–72 hours, choose lighter-coloured foods such as white rice, pasta, chicken, fish and potatoes, and avoid strongly pigmented foods and drinks such as coffee, tea and red wine. If your teeth feel sensitive, avoid very hot or cold foods and drinks for the first few hours.

For the first 48–72 hours after your teeth whitening treatment, we recommend avoiding strongly pigmented foods and drinks that may contribute to staining.

This includes coffee, tea, red wine, dark or colourful juices, berries, beetroot, soy sauce and other strongly coloured foods. We also recommend avoiding smoking during this period. If your teeth feel sensitive after treatment, limit very acidic foods and drinks such as citrus and avoid very hot or cold temperatures until the sensitivity settles.

Your teeth can be more susceptible to staining immediately after a teeth whitening treatment, which is why your food and drink choices are important during the first 48–72 hours.

Avoiding strongly pigmented foods and drinks during this time can help minimise new surface staining and protect the appearance of your whitening results. Following your aftercare instructions and maintaining good oral hygiene can also help keep your smile looking brighter for longer.
