You should have healthy teeth and gums, and your teeth shouldn't be too sensitive. People with gum disease, cavities, worn enamel, or exposed roots may need to seek treatment before getting teeth whitening.

The most common side effects are temporary tooth sensitivity and gum or mouth irritation. This may last for a day only.

The results can last up to 3-5 years, but it depends on your lifestyle and oral health.

Before your appointment, you should brush your teeth and avoid staining drinks and foods. After your treatment, you should avoid smoking for at least a week and maintain your results by flossing and brushing twice a day.

You can use a maintenance kit every 3-6 months to keep your teeth looking their best.

Ideally for 24-48 hours. This will stop your teeth from absorbing any stains and maintain the whiteness and sparkle.

Teeth whitening doesn't affect fillings, bridges, veneers, or crowns, but it also doesn't change the colour of these restorations. This can result in an uneven shade between your teeth and your restorations. You might want to consider a separate procedure to match your restorations to your teeth's new colour.
