What does this aftercare section cover?
This section covers whitening aftercare, from the time around treatment to the longer term. It does not explain how whitening works or who can have it.
How is the immediate window different from ongoing care?
The immediate window is the time around treatment, and ongoing care is what follows. At Deepcar Dental Care, the aftercare advice is to avoid smoking during treatment and to follow a white diet for 2 weeks after treatment. Ongoing care covers the longer term, including top-ups and looking after your whitening trays.

Which aftercare topic do you need?
The white diet, how long whitening lasts, and top-ups each have their own aftercare page.
The white diet
For 2 weeks after whitening treatment, the practice advises a white diet, which means choosing foods and drinks that are less likely to stain teeth. Read about what to eat and drink on the white diet.
Longevity
Whitening over the longer term is covered on the longevity page rather than here. Read about what affects how long whitening lasts.
Top-ups and trays
At Deepcar Dental Care, a top-up is recommended every 6 months, and top-up kits are available for previous patients. Whitening trays last around 2 years if they are well looked after. Read about top-ups and caring for your trays.
What is covered elsewhere?
Sensitivity during and after whitening is covered in the whitening safety section, not on this page. NHS guidance is to talk to your dentist if any side effects bother you. Read about how whitening affects sensitivity and enamel. The guide to teeth whitening explains how whitening works and what the law says. To read about who can have whitening, browse the eligibility section. The science section explains why teeth change colour. The main page describes teeth whitening with a dentist.
Frequently asked questions
What everyday brushing routine does NHS guidance recommend?
NHS guidance is to brush twice a day for about 2 minutes, using a toothpaste with at least 1,350 ppm fluoride for adults. This is general everyday guidance, and it sits alongside the white diet that Deepcar Dental Care advises for 2 weeks after whitening treatment.
Is smoking part of whitening aftercare?
Yes. Avoiding smoking during treatment is part of Deepcar Dental Care's aftercare advice. NHS guidance lists smoking among the causes of tooth staining, and a 2024 systematic review notes that professional whitening guidelines recommend stopping smoking. Smoking cessation advice is available at the practice.
Will whitening change the colour of crowns, veneers or fillings?
No. Crowns, veneers and fillings will not change colour with whitening, and NHS guidance says whitening can only lighten the colour of natural teeth. Having many front crowns or veneers is one of the reasons the practice gives for whitening not being suitable. Read about how existing dental work responds to whitening.
