What is professional teeth whitening?
Professional teeth whitening is a cosmetic dental procedure that uses active agents based on hydrogen peroxide or carbamide peroxide to oxidize pigment molecules deposited in the superficial and deeper layers of enamel and dentin. Unlike over-the-counter products — whitening toothpastes, adhesive strips or kit-based trays with low concentrations — professional treatment uses higher-concentration formulations applied and monitored by a dentist, with significantly better and faster results.
Teeth naturally discolour over time due to several factors: consumption of coloured foods and drinks (coffee, tea, red wine, cola, berries), smoking, certain medications (tetracycline), fluorosis, dental trauma or simply the ageing process, which makes enamel more translucent and allows the yellowish dentin to show through. Professional whitening acts effectively on most extrinsic staining categories and partially on intrinsic discolouration, depending on its cause and severity.
There are two main approaches to professional whitening: in-office treatment, performed in one or more 60–90 minute sessions at the clinic, and take-home whitening with customized trays, where the patient wears the gel-loaded trays for a few hours per day or overnight, following the dentist's instructions. The best results are often achieved through a combined protocol that blends the advantages of both techniques.
At BioEstetic Dent, teeth whitening is preceded by a thorough consultation: the health of teeth and gums is assessed, existing cavities or restorations are identified, the patient's expectations are discussed and realistic treatment outcomes are established. Not every tooth responds equally, and existing ceramic or composite restorations do not change shade along with natural enamel — an important factor to clarify before treatment begins.
Why professional whitening instead of commercial products?
The market is flooded with whitening products: abrasive toothpastes, adhesive strips, standard tray kits with included gel, whitening pens and whitening mouthwashes. All share low concentrations of active agent, uneven application and modest results, mainly visible for mild surface staining. Pharmacy products cannot penetrate enamel as effectively as professional systems, and universal trays do not fit precisely, allowing gel to leak onto the gums.
Professional whitening performed by a dentist has clear advantages: the concentration of the active agent is matched to the patient's needs, the dentist checks gum and enamel health before application, trays are made on individual impressions for optimal contact with the tooth surface and uniform gel distribution. The risk of gum irritation or hypersensitivity is significantly reduced compared to uncontrolled self-application.
Safety is an often-overlooked aspect: whitening performed on teeth with untreated cavities, defective restorations or inflamed gums can cause pain, extreme sensitivity or pulp damage. The dentist assesses whether treatment is appropriate, postpones whitening until existing problems are resolved and monitors reactions throughout.
Modern professional systems — such as Opalescence used at BioEstetic Dent — are formulated with enamel-protective ingredients (fluoride, potassium nitrate) that reduce sensitivity and remineralize enamel during treatment. The end result is not just a whiter smile, but better-monitored and better-cared-for enamel.
Types of teeth whitening treatment
We choose the right protocol based on initial shade, sensitivity, lifestyle and the aesthetic goals of each patient.
Professional in-office whitening
Treatment is performed in one or two 60–90 minute sessions at the clinic. A high-concentration whitening gel is applied to the tooth surfaces with gum protection in place, acting in repeated cycles. Results are visible immediately at the end of the session.
- Fast visible effect — up to 8–10 shades whiter
- Direct dentist monitoring throughout the session
- Ideal for patients with a busy schedule
- Gum and enamel protection included in the protocol
- Immediate result verified on the vita shade scale
Customized take-home whitening trays
An impression of your teeth is taken and custom thermoformed trays are fabricated to fit your anatomy precisely. You receive Opalescence PF whitening gel with clear instructions — usually 1–2 hours per day or worn overnight for 1–2 weeks, depending on the chosen concentration.
- Superior comfort from fully personalized trays
- Complete control over the pace and intensity of whitening
- Easy continuation or renewal of treatment when needed
- Professional-grade gel with fluoride and potassium nitrate
- Progressive, natural-looking results adaptable to lifestyle
Combined protocol — in-office and take-home
The most effective approach: start with an intensive in-office whitening session, followed by a consolidation and deepening programme at home with your custom trays. This combination delivers maximum results and ensures colour uniformity across all tooth surfaces.
- Maximum results — exceeding 10 shades in some cases
- Colour consolidation and uniformity over time
- Additional enamel protection through fluoride home gels
- Perfect for weddings, special events or personal rebranding
- Best efficiency-to-durability ratio of all protocols
Maintenance whitening
Once the desired result is achieved, long-term maintenance requires periodic gel applications with the custom trays, once or twice a year. This preventive approach stops gradual restaining and extends the effect of the initial treatment without new intensive sessions.
- Significant extension of the initial treatment effect
- Simple home application with existing trays
- Lower cost compared to repeating full treatment
- Adaptable to dietary habits and lifestyle
- Recommended once every 6–12 months
Safety of teeth whitening — what you need to know
Professional teeth whitening, when performed correctly, is a safe procedure for enamel and dentin, with minimal risks when carried out by a qualified dentist. Long-term clinical studies show that hydrogen peroxide and carbamide peroxide, at the concentrations used in dentistry, do not cause permanent structural damage to enamel when the protocol is followed correctly.
The most common side effect is transient dental sensitivity — a feeling of discomfort at cold, warm or sweet stimuli occurring during or immediately after treatment. This typically resolves within 24–72 hours. Patients with pre-existing sensitivity, thinned enamel or gum recession require careful evaluation and may benefit from desensitizing gels applied before or after whitening.
Gum irritation is another possible effect, especially if gel contacts soft tissues. In-office whitening uses a protective gum barrier before gel application. With take-home whitening, well-fitted custom trays minimize gel contact with the gums. If irritation occurs, application frequency or gel concentration can be reduced.
Whitening is not recommended for pregnant or breastfeeding women, children and adolescents with still-developing dental pulp, or patients with active untreated cavities or inflamed gums. This is why the prior consultation is not optional — it is an essential safety step that protects both the patient and the treatment outcome.
Opalescence — the professional whitening system chosen at BioEstetic Dent
At BioEstetic Dent, we use Opalescence whitening systems, one of the most researched and widely used professional brands worldwide, manufactured by Ultradent Products. Opalescence Boost is formulated with chemically activated 40% hydrogen peroxide, without the need for a whitening lamp, which reduces the risk of thermal sensitivity and ensures uniform distribution of the active agent across the tooth surface.
The Opalescence formulation includes fluoride and potassium nitrate — ingredients that remineralize enamel during treatment and significantly reduce post-whitening sensitivity. This distinguishes professional systems from over-the-counter products, which typically contain no protective agents. The result is enamel that is not only whiter, but also more resilient and less reactive to stimuli.
For take-home whitening, we use Opalescence PF gels in various concentrations (10%, 16%, 20% or 35%), adapted to the patient's schedule: lower concentrations are worn for longer periods or overnight, while higher concentrations are applied for shorter sessions. The dentist selects the optimal concentration based on sensitivity and aesthetic goals.
Professional whitening systems also offer the advantage of traceability and controlled quality: each gel batch is tested and certified, and the dentist can document initial and final shades using the vita shade scale, providing objective evidence of progress. This transparency is part of the BioEstetic Dent quality standard.
How long does whitening last and how do you maintain it?
The duration of the whitening effect varies depending on dietary habits, oral hygiene, frequency of consumption of staining substances and the type of treatment performed. On average, professional whitening maintains results for 1–3 years when maintenance recommendations are followed. Patients who avoid coffee and tobacco and maintain rigorous oral hygiene can enjoy visible results for even longer.
Restaining is a natural process and does not mean the treatment has failed. Enamel is microscopically porous and gradually absorbs pigments from food and drinks over time. This is why the maintenance programme with custom trays — a few applications once or twice a year — is the simplest and most economical way to extend the effect without repeating intensive treatment.
Coloured foods and drinks (coffee, tea, red wine, cola, turmeric or tomato-based sauces) are the main restaining factors. It is recommended to avoid them or drink water afterwards during the first 48 hours after whitening — this is when enamel is most porous and most susceptible to pigment absorption. In the long term, moderating intake and brushing after chromatic meals helps significantly.
Professional periodic hygiene (scaling, air-flow) before a whitening session or as part of the maintenance programme optimizes results: it removes tartar and surface deposits that can hinder gel penetration and evens out tooth colour. At BioEstetic Dent, hygiene and whitening are frequently recommended together as part of a complete aesthetic plan.

- 5
Maintenance programme
The dentist advises on recommended dietary habits, oral hygiene and the frequency of periodic maintenance applications with the custom trays.
Post-whitening care — practical recommendations
The first 48 hours after whitening are critical for maintaining results: enamel is temporarily more porous and susceptible to pigment absorption. Avoid strongly coloured foods and drinks (coffee, tea, wine, cola, sauces, berries, turmeric), tobacco and acidic beverages. This period is commonly known as the 'white diet' — focus on light-coloured foods: chicken, fish, rice, potatoes, bananas, apples, milk and yoghurt.
In the long term, reducing staining substances, correct oral hygiene (brushing twice daily, flossing, alcohol-free and dye-free mouthwash), regular check-ups and professional hygiene all help prolong the effect. A fluoride toothpaste or one formulated for sensitive teeth is recommended in the weeks following treatment.
Existing ceramic restorations — crowns, veneers — do not whiten along with natural enamel. If you are planning a full aesthetic rehabilitation, the dentist may recommend whitening first, followed by fabricating restorations in the new lighter shade. Veneers or crowns made before whitening may appear darker than the whitened teeth and may eventually need replacing.
Transient sensitivity can be managed with toothpaste for sensitive teeth (with potassium nitrate or arginine), desensitizing gel applied in trays or, if severe, with standard over-the-counter analgesics for a short time. The sensation resolves within 24–72 hours in the vast majority of cases. Contact the clinic if pain is intense or persistent — it may indicate a pre-existing issue requiring attention.
