Teeth Whitening
Professional whitening lightens the natural shade of teeth using a controlled bleaching agent. It works on natural tooth structure and does not change the colour of existing fillings, crowns or veneers.
Treatment overview
Whitening agents break down the compounds that cause discolouration within enamel and dentine. Applied under professional supervision, the concentration and contact time are controlled.
Treatment may be carried out in the clinic, with custom trays for use at home, or as a combination. Which is appropriate depends on the type of discolouration and the condition of your teeth and gums.
A check-up comes first. Whitening an untreated cavity or inflamed gums is uncomfortable and can be harmful.
Why patients consider teeth whitening
- Teeth have gradually darkened with age or from dietary staining.
- You would like a lighter shade before other cosmetic treatment is planned.
- Surface stains remain after professional cleaning.
Consultation and suitability
Existing restorations do not lighten, so visible fillings or crowns may need replacing after whitening to match the new shade.
Sensitivity history, gum recession and enamel wear all influence whether whitening is advisable and how it is carried out.
Some types of internal discolouration respond less predictably than surface staining.
Whitening is not carried out during pregnancy or breastfeeding, and age restrictions apply.
A clinical examination is required before any treatment plan can be confirmed. Suitability depends on your individual oral health.
The treatment process
Examination
Assessment of the cause of discolouration, existing restorations, gum health and any sensitivity.
Cleaning
Professional cleaning is usually carried out first so the agent contacts the tooth surface evenly.
Shade record
A starting shade is recorded so change can be judged objectively.
Whitening
In-clinic application, custom trays for home use, or a combination as agreed.
Review
The result is assessed and maintenance advice given.
Aftercare
- Expect some sensitivity for a short period; tell your dentist if it is marked or persistent.
- Limit strongly staining food and drink in the days following treatment, as advised.
- Maintain daily cleaning and routine professional cleaning appointments.
- Any top-up should be carried out under professional guidance rather than with unregulated products.
Limitations and risks
Every treatment has trade-offs. These are the ones worth understanding before you decide.
- Whitening does not lighten fillings, crowns, bridges or veneers.
- Results vary depending on the cause of discolouration; some types respond less than others.
- Sensitivity during or after treatment is common and usually temporary.
- The effect is not permanent and gradually reduces over time.
- Whitening does not treat decay or gum disease.

Frequently asked questions
Professionally supervised whitening with controlled products is used widely. Your dentist assesses your enamel and gums first and adjusts the approach to reduce sensitivity.
Whitening agents act on natural tooth structure. Ceramic and composite restorations keep their original shade, which is why the sequence of treatment matters.
This varies with diet, smoking and oral hygiene. The shade gradually returns towards its previous level over time.
No. Suitability depends on the cause of discolouration, existing restorations, gum health and medical factors. An examination is required.
