A patient may choose to bleach their teeth for a variety of reasons, including noticeable discolouration or simply a desire to achieve a brighter, more radiant smile. The teeth‑whitening process typically takes around three days to complete, depending on the method used and the individual’s response to treatment.
During this period, patients are strongly advised to avoid foods and beverages that are known to cause staining—such as coffee, tea, red wine, berries, and coloured sauces—to ensure the best possible whitening results and maintain the effectiveness of the treatment.
