The first 48 hours after your teeth whitening treatment is when your teeth are particularly susceptible to not only sensitivity, but also staining. Therefore, you should be cautious of what you eat and drink during this time period. We additionally recommend being mindful of your daily lifestyle and eating habits after your teeth whitening treatment has finished. This will help to keep your new smile looking bright and dazzling for longer.

The first 48 hours

So, how long after teeth whitening can I eat normally? Whether you have had your treatment carried out in a private dental clinic or doing your teeth whitening at home, the answer remains the same. During the first 48 hours, your teeth will probably feel quite sensitive. To diminish discomfort, try to avoid consuming anything too hot or too cold that can trigger your teeth sensitivity. Stick to lukewarm temperatures if possible. This time period is also when your smile is at its most susceptible for discolouration. That is why we recommend consuming as much light and white-coloured food and drinks as possible (something also known as the ‘White Diet’). Sticking to the ‘White Diet’ after teeth whitening helps to protect the vibrancy of your new smile. If you have any concerns about cutting certain foods from your everyday routine, consult with your doctor or dietician prior to your whitening treatment.

How to manage tooth sensitivity after whitening

As mentioned earlier, tooth sensitivity is a common side effect of teeth whitening. We recommend using a sensitive toothpaste and making sure that anything you eat or drink isn’t too extreme of a temperature. Try taking your usual over-the-counter pain medication too. However, if the discomfort persists, contact your dentist.

Maintaining your bright white smile

Being mindful of your diet is not the only way to protect the whiteness of your brand-new smile - the following will also help to maintain your results.

  • Have a great oral hygiene routine: Brush your teeth twice a day with a high-quality toothbrush and a whitening toothpaste. Remember to floss afterwards.
  • Don’t skip the dentist: Attend two routine check-ups and two hygienist appointments per year with your dental clinic.
  • Use a straw: This is particularly helpful if you like caffeine. Drinking with a straw helps to limit the contact between the staining liquid and your teeth.
  • Top-up your teeth whitening treatment: Yorkshire Dental Suite provides top-up teeth whitening syringes, allowing you to refresh your colour as desired.
