Short answer: Professional whitening can lighten natural teeth after an oral-health assessment. Results vary according to the initial shade and cause of staining. Temporary sensitivity is possible, even with a protocol designed to improve comfort.

Who may be suitable for professional teeth whitening?

Whitening mainly affects discolouration within natural teeth. Crowns, veneers, bridges and composite restorations do not lighten in the same way. A prior examination is important to identify decay, cracks, gum inflammation, exposed roots or restorations that could affect comfort and the final appearance.

The assessment also helps determine whether whitening is the right approach. Some isolated or deep discolourations may require a different cosmetic or restorative solution.

How does the BlancOne protocol work?

After the lips and gums are protected, the whitening product is applied to the teeth and activated according to the selected protocol. The choice between an in-clinic appointment and any complementary protocol depends on your goal, initial shade, dental history and sensitivity.

The brand name does not replace clinical judgement. Product concentration, contact time and the number of applications should be chosen and supervised by a dental professional.

What results can you expect?

The degree of lightening varies from person to person. Staining associated with coffee, tea, tobacco, ageing or medicines does not respond identically. The shade can also change again over time depending on diet, smoking and oral hygiene.

For this reason, the clinic does not guarantee a fixed number of shades or an exact duration. Standardised photographs and shade records allow a more objective before-and-after comparison.

Sensitivity and precautions

Temporary sensitivity to cold may occur.
Gum irritation is possible if whitening gel contacts soft tissues.
Visible restorations may need later aesthetic adjustment because they do not whiten.
Pregnancy, breastfeeding, decay, gum disease and significant sensitivity should be discussed before treatment.
Whitening should follow, not replace, diagnosis and preventive care.

How to maintain the result

Good oral hygiene, regular examinations and moderation of strongly coloured drinks can help maintain the result. Smoking may accelerate new staining. Avoid unsupervised abrasive products: they may wear tooth tissue or increase sensitivity without changing the internal shade in a predictable way.

Frequently asked questions

Is teeth whitening completely painless?

Many patients tolerate it well, but temporary sensitivity remains possible and varies with the protocol and the individual.

Will crowns or fillings become lighter?

No. Restorative materials do not respond like natural teeth and may need to be reassessed after whitening.

How long do whitening results last?

Stability depends on the initial shade, oral hygiene, smoking, diet and follow-up. An exact duration cannot be guaranteed.

Should I have a dental cleaning before whitening?

If plaque, calculus or external stains are present, professional cleaning may be recommended first so the assessment and shade comparison are more reliable.
