Teeth whitening

A brighter smile without drilling and without changing the shape of your teeth — at home with custom-made trays or in the clinic under professional supervision.

What is teeth whitening?

Whitening is a procedure that lightens the natural colour of the teeth. The whitening gel contains peroxide, which penetrates the enamel and dentine and breaks down coloured molecules — pigments from coffee, tea, red wine and tobacco, or those that come with age.

Unlike polishing or whitening toothpastes, which only remove surface stains, professional whitening changes the colour of the tooth itself. The tooth is not drilled and its shape does not change.

How much lighter the teeth become depends on the type of staining, the starting shade and the thickness of the enamel. Whitening is therefore always preceded by an examination: we check for decay, damaged fillings or receding gums and assess what result can realistically be expected.

Who it is for

Who is whitening for?

Whitening suits adults with healthy teeth and gums who would like a lighter shade, for example with:

  • yellowed teeth from coffee, tea, wine or smoking
  • a naturally darker tooth shade
  • teeth that have darkened with age
  • preparation for cosmetic work — so that new veneers or crowns can be made in a lighter shade

Before whitening, the dentist examines your teeth and gums. Whitening is not carried out with untreated decay or gum inflammation, is generally postponed during pregnancy and breastfeeding, and is not carried out for anyone under 18. Fillings, crowns and veneers do not change colour.

How we whiten teeth

We whiten with Opalescence gels — at home, with upper and lower trays and four gels, or in the clinic.

For take-home whitening we take an impression of your teeth and make custom upper and lower trays. The trays fit closely, so the gel stays on the teeth rather than the gums. The kit includes four whitening gels and instructions on how and for how long to wear the trays.

In-office whitening is carried out in the dental chair under supervision. The gums are protected before the gel is applied directly to the teeth. It suits patients who want a visible change in a shorter time.

Opalescence gels are peroxide-based, and the take-home and in-office products differ in concentration and application time. That is why take-home whitening follows your dentist’s instructions, while in-office whitening is supervised at the clinic. We agree on the right method for you after the examination.

Take-home whitening
Upper and lower trays + 4 gels
In-office whitening
At the clinic, with gum protection

Custom trays

Made from an impression of your teeth for even contact with the gel.

Examination first

Decay, damaged fillings and sensitive tooth necks are treated before whitening begins.

The trays are yours

You can use the same trays later for occasional top-ups.

Take-home or in-office whitening?

Both methods can give a lovely result. They differ in pace, how they are carried out and whether wearing trays suits you.

Take-home whitening

Custom upper and lower trays + 4 gels, with your dentist’s instructions.

  • Gradual lightening over several days or weeks
  • Done at home, overnight
  • Trays can be reused for later top-ups

In-office whitening

Whitening at the clinic, with gum protection and professional supervision.

  • A visible change in a shorter time
  • No trays to wear at home
  • Suitable, for example, before an important event

The final result depends on your starting shade and type of staining, not only on the method chosen.

Procedure

What does the procedure involve?

  1. Examination

    We check your teeth, fillings and gums and record your starting shade.

  2. Preparation

    Scaling and treatment of any decay before whitening, if needed.

  3. Impression or gum protection

    For take-home whitening we take an impression for the trays; for in-office whitening the gums are protected before the gel is applied.

  4. Whitening

    At home following instructions, wearing the trays with gel — or at the clinic in a single visit.

  5. Shade check

    We compare the result with the starting shade and agree on any further steps.

Benefits

Benefits of whitening

No drilling

The tooth is not prepared and its shape stays the same.

Changes the tooth’s colour

Acts on pigments within the tooth, not just surface stains.

Professional supervision

Whitening follows an examination and is guided by your dentist.

Two methods

Choose between gradual take-home and faster in-office whitening.

A start for cosmetic work

A lighter shade can be the basis for later veneers or crowns.

Realistic expectations

  • Fillings, crowns and veneers do not whiten — after whitening they sometimes need replacing to match.
  • Some stains (e.g. from certain medications or in root-treated teeth) respond less well to whitening.
  • The result is not permanent: over time, especially with staining food and drink, the colour gradually returns — though not completely to the original shade.

Duration and recovery

Duration and recovery

In-office whitening
One visit
Take-home whitening
Several days to several weeks, as instructed
Tooth sensitivity
Common, usually temporary
Anaesthesia
Not needed

During and after whitening, teeth may be more sensitive to cold. This is usually temporary and settles once whitening is finished; if needed, we recommend a toothpaste for sensitive teeth or longer breaks between gel applications.

For the first days after whitening, we advise avoiding strongly coloured food and drink — coffee, tea, red wine, sauces — and smoking.

The length of treatment and the intensity of the result depend on your starting shade and the individual case.

Results and maintenance

Results and maintenance

The result is visibly lighter, natural-looking teeth. How long the lighter shade lasts depends on diet, smoking and oral hygiene.

Over time the colour of the teeth gradually returns, but not completely to the original shade. The result can be refreshed with occasional shorter whitening, as agreed with your dentist — for take-home whitening, using the same trays.

Keeping your teeth lighter

  • Limit coffee, tea, red wine and strongly coloured food, or rinse with water afterwards
  • Do not smoke
  • Regular professional cleaning and polishing
  • Occasional whitening top-ups as agreed

Which whitening gel do you use?

We use Opalescence gels. The take-home and in-office products differ in concentration and application, and the choice depends on your examination and preferences.

Does whitening damage the enamel?

Professional whitening carried out after an examination and according to your dentist’s instructions is considered a safe procedure for healthy teeth. The most common side effect is temporary tooth sensitivity.

How long does the result last?

It varies from person to person and depends mainly on diet, smoking and hygiene. The colour gradually returns, though not completely to the original shade, and the result can be refreshed with a shorter whitening session.

Do fillings, crowns and veneers whiten too?

No. Whitening works only on natural teeth. If you have visible fillings or crowns on your front teeth, they sometimes need replacing after whitening so the colour matches — we discuss this in advance.

Is take-home or in-office whitening better?

Both can give a good result. Take-home whitening is more gradual and uses trays at home; in-office whitening gives a change in a shorter time. The choice depends on your preferences, schedule and examination findings.

Will my teeth hurt?

Some patients experience temporary sensitivity to cold. It usually settles once whitening is finished and can be eased with a toothpaste for sensitive teeth and by adjusting how the gel is used.

Can I whiten my teeth during pregnancy?

Whitening is generally postponed during pregnancy and breastfeeding. A cosmetic procedure can wait — and you are always welcome to ask us about routine dental care during pregnancy.
