What is teeth whitening?
Teeth whitening is a cosmetic dental treatment that lightens the colour of your natural teeth. A bleaching gel, usually based on hydrogen peroxide, is applied to the teeth. The gel releases oxygen that breaks down the pigment molecules trapped in the enamel and the layer beneath it, so the tooth reflects more light and looks whiter.
In-clinic, or professional, whitening uses a stronger gel than home kits sold in shops. Because the dentist protects your gums and controls the process, it can safely achieve a bigger change in a single appointment. A special light or laser is often used to speed up the reaction.
Who is it suitable for?
Teeth naturally darken with age, and staining builds up from coffee, tea, red wine, cola, curry and smoking. Poor cleaning lets plaque and tartar build up and hold stains too. Whitening works best if you:
- Have healthy teeth and gums with no untreated decay
- Have yellow or brown staining from food, drink, smoking or ageing
- Have few or no fillings, crowns or veneers on your front teeth
- Have realistic expectations about the shade that can be reached
Whitening is less effective for grey staining caused by certain antibiotics, for very dark staining, or where too much fluoride has marked the enamel. In these cases laminates or bonding may give a better result. Whitening is not usually recommended during pregnancy or breastfeeding, or for people under 18.
How the procedure is done
Examination
The dentist checks your teeth and gums and records your starting shade. If needed, a scale and polish removes tartar and surface stains, so the gel can work evenly.
Protecting the gums
A cheek retractor keeps your lips away from your teeth, and a protective barrier is painted over the gums. This prevents the bleaching gel from irritating the soft tissue.
Applying the gel
The whitening gel is applied to the front surfaces of your teeth. A light or laser is shone on them to activate the gel. The gel is usually left on for about 15 minutes, removed and reapplied two or three times.
Checking the shade
Once the gel is cleaned off, the dentist compares your new shade with the starting one. A desensitising gel may be applied. The whole visit usually takes 45 to 90 minutes, and you see the difference straight away.
Recovery timeline
- First 48 hours
The teeth are at their most porous and most likely to pick up new stains. You may feel sensitivity to hot and cold, which usually settles within one to two days.
- First two weeks
The shade can settle very slightly as the teeth rehydrate. Keep avoiding strongly coloured food and drink as much as you can.
- Long term
The teeth gradually darken again over time. Many people choose a top-up treatment every year or two.
Aftercare
To protect your result, for at least the first 48 hours, and ideally the first two weeks:
- Avoid coffee, tea, red wine, cola and fruit juices with strong colours
- Avoid dark sauces such as soy, curry and tomato sauce, and strongly coloured berries
- Limit acidic fruit and drinks, which can increase sensitivity
- Do not smoke or use other tobacco products
- Avoid coloured mouthwash and toothpaste
- Drink through a straw if you have coloured drinks
In the long term, brush twice a day, clean between your teeth and have regular dental check-ups.
Risks and side effects
Professional whitening is a low-risk treatment, but you should know about:
- Tooth sensitivity, usually temporary
- Gum irritation or, rarely, a small chemical burn if gel touches the gums, which usually heals within a few days
- Uneven results if you have fillings, crowns or veneers that do not change colour
- A result less dramatic than hoped, especially with grey or deep staining
Telling the dentist if you feel discomfort during treatment helps keep side effects to a minimum.
Results
Your teeth are visibly lighter as soon as you leave the clinic. Results usually last from one to three years, depending on your diet, whether you smoke and how well you look after your teeth.

Teeth Whitening FAQ
How much whiter will my teeth get?
Most people see their teeth lighten by several shades in one session. The exact change depends on the type of staining and the natural colour of your teeth. Yellow staining usually responds better than grey staining.
Does teeth whitening hurt?
The treatment itself is not painful, but some people feel brief zings of sensitivity during or after it. This usually settles within a day or two, and a desensitising gel can help.
Will whitening work on my crowns, fillings or veneers?
No. Whitening only changes the colour of natural tooth enamel, not crowns, fillings, veneers or other restorations. If they are on visible teeth, they may need replacing afterwards to match your new shade.
How long do the results last?
Results usually last from one to three years. Coffee, tea, red wine and smoking will make teeth darken more quickly, while good oral hygiene and occasional top-ups help results last.
Is teeth whitening safe for my enamel?
When done by a dentist, with protection for your gums, professional whitening is considered safe for healthy enamel. The dentist checks your teeth first and does not whiten teeth with untreated decay or gum disease.
Can teeth whitening be combined with other dental treatment?
Yes. Many people have a scale and polish first, and whitening is often done before laminates or crowns so the new restorations can be matched to the whiter shade.
