When to get teeth whitening?
Teeth whitening responds to an aesthetic demand: a yellowish shade, unsightly stains or a major event such as a wedding. Dr. Hikmat first carries out a complete assessment to check that the discolouration can actually be improved, since not all types react in the same way.
- Tea, coffee or tobacco stains.
- An overall darkened shade with age.
- Discolouration that persists after scaling.
- A wish to lighten the natural shade for a brighter smile.
A cavity, inflamed gums or high sensitivity must be treated before any session, and prior scaling improves the evenness of the result. According to the World Health Organization, more than 3.5 billion people worldwide suffer from oral diseases: health always comes before aesthetics.
The assessment is also the moment to talk about expectations: whitening brightens the natural shade of the teeth, but it cannot correct the shape, length or alignment of the teeth. If the shade is uneven or the enamel is thin, other aesthetic treatments can be proposed to complete the result.
Proposed methods
Two approaches coexist. In-office, the practitioner applies a hydrogen peroxide gel, often activated by a light source, for an immediate result in one to three short sessions. At home, custom-made trays worn over several weeks provide a gradual, gentler lightening, ideal for sensitive teeth.
The Haute Autorité de Santé (French Health Authority) reminds us that, in Europe, products containing more than 0.1% hydrogen peroxide are for professional use and can only be supplied by a practitioner: a protection for enamel and gums. High-concentration gels remain reserved for the dental office.
- In-office: one to three short sessions, ideal before an event.
- At home: custom-made trays, regular application over several weeks.
- Combining both methods often prolongs the result.
The choice of method depends on the initial shade, the desired timeframe and each person's sensitivity; the practitioner guides you towards the most suitable solution.
Some products sold online promise rapid whitening at low cost, but their concentration and pH are not controlled: they can burn the gums, damage the enamel or give a heterogeneous result. Only a professional product, applied in an adapted protocol, offers a predictable and safe outcome.
Precautions and contraindications
Whitening is never done without an assessment: up-to-date hygiene, recent scaling and healthy gums are the basic conditions, verified by the practitioner before any application. A sensitivity check also makes it possible to adjust the protocol before starting.
- Contraindicated during pregnancy and breastfeeding.
- Not recommended before 18 years of age, when the enamel is still immature.
- Excluded in case of allergy to peroxide.
- Certain stains (medication, fluorosis) respond less well.
The Agadir practice applies these rules systematically. According to the American Dental Association, controlled whitening does not weaken the enamel when instructions are followed. After treatment, a check-up verifies that there is no gum irritation and that the shade is progressing well.
The gum-protective resin applied at the start of each in-office session is what makes the treatment safe: it confines the gel to the tooth surface and prevents any contact with the soft tissues. This protection is impossible to reproduce at home, which is another reason to favour the professional route.
Sensitivity and comfort during treatment
Transient sensitivity is the main side effect. It appears during the sessions or a few days afterwards, then disappears on its own. Desensitising toothpastes and fluoride gels noticeably reduce it.
Dr. Hikmat adjusts the concentration and duration of the applications according to each person's reaction, to prioritise comfort while maintaining a visible result. In case of persistent sensitivity, applying fluoride varnish in-office provides lasting relief.
Duration and maintenance
The result is noticeable from the first sessions and stabilises within a few weeks. Its duration depends on habits: tobacco and highly coloured drinks speed up the return of the shade.
- Brush your teeth twice a day with a fluoride toothpaste.
- Avoid tobacco, tea and coffee within 48 hours of the session.
- Plan touch-ups, usually once a year.
Follow-up at the practice, in Agadir, makes it possible to monitor the stability of the result and to plan touch-ups over time. A balanced diet and regular hydration also help preserve the brightness of the smile.
Good oral hygiene is the first maintenance factor: a clean tooth surface keeps the stain-free shade longer. Regular scaling removes the deposits that yellow the smile, and annual touch-ups are enough in most cases.
Frequently asked questions
Does teeth whitening damage enamel?
No, when it is carried out by a professional after an assessment. Controlled-dose hydrogen peroxide acts on discolouration without altering the enamel, in compliance with regulated concentrations. Sessions are short and application times are limited to preserve the tissues.
How long does the result last?
On average one to three years depending on dietary habits and tobacco. An annual touch-up is generally enough to prolong the effect. Highly coloured drinks and tobacco speed up the return of stains.
Is whitening suitable for everyone?
No, not everyone is a candidate. It is contraindicated during pregnancy, breastfeeding, before the age of 18 and in case of allergy to peroxide. The prior assessment at the practice ensures you meet the criteria.
What is the difference between scaling and whitening?
Scaling removes tartar and superficial stains without changing the colour of the tooth, and it treats the gums. Whitening acts in depth on the colour of the enamel. Scaling often precedes whitening for a more even result.
