Teeth whitening in Lisbon with safe and natural results

  • Personalized planning and sensitivity assessment
  • Natural results, without an “artificial smile”

How it works and who it’s suitable for

Whitening is a conservative procedure that does not wear down or weaken the tooth structure when performed under clinical supervision. The treatment exclusively targets the pigments responsible for darkening, progressively restoring a lighter and more uniform shade. For this reason, it is a safe option for most people who wish to improve the aesthetics of their smile without resorting to invasive treatments.


Before starting any whitening, it is essential to assess oral health globally. Cavities, gum inflammation, or enamel changes should be treated beforehand to ensure not only the effectiveness of the whitening but also comfort during the process. In cases where there are visible restorations or dental veneers, planning becomes even more important to ensure that the final result is harmonious and balanced.

Whitening with maximum safety

More than just “whitening teeth,” Mint’s goal is to treat the smile safely, respecting dental anatomy and each person’s sensitivity. The process is structured in clear stages:

Complete clinical evaluation

The dentist assesses the current tooth color, gum health, enamel condition, and the presence of restorations, crowns, or dental veneers. We only proceed if everything is clinically stable.

Objective color planning

We define the desired shade together, always within natural limits. We explain what is realistically possible and what would be excessive for your case.

Personalized treatment

We choose the type of whitening (in-office, combined, or supervised at-home) and adjust the gel concentration to your tooth sensitivity.

Follow-up and maintenance

After the treatment, we follow up with you. We recommend habits to maintain the color for longer and, when indicated, gentle maintenance sessions.

Step-by-step of your whitening at Mint

Each stage of whitening at Mint Clinic is designed to provide predictability and tranquility. From the first consultation, the patient knows exactly what to expect in terms of treatment duration, number of sessions, and necessary care. This approach reduces anxiety and increases confidence in the process, making the experience more comfortable.

After whitening, clear guidelines are provided on diet, oral hygiene, and habits to avoid in the following days. Small care makes a big difference in the stability of the result, allowing you to keep your smile whiter for longer without frequent interventions.

PHASE 1 — Evaluation Consultation

We collect clinical history, assess teeth and gums, and, if necessary, recommend an oral hygiene session before whitening.

PHASE 2 — Photographs and color registration

We take clinical photographs and measure the current tooth color with a specific scale, so you can see the before and after accurately.

PHASE 3 — Selection of the ideal protocol

We define whether the best option is in-office whitening, combined (office + trays at home), or supervised at-home, always adjusted to your lifestyle.

PHASE 4 – Whitening session

We protect gums and soft tissues, apply the whitening gel, and monitor the entire procedure. The priority is comfort and safety.

PHASE 5 – Review and maintenance plan

We compare the results with the initial color, adjust expectations, and create your maintenance plan to prolong the whitening effect.

Types of whitening available at Mint Clinic

Not everyone has the same lifestyle, available time, or dental sensitivity. Therefore, at Mint, we work with different whitening protocols, always supervised by dentists.

The choice of whitening type should respect not only the aesthetic goal but also each person’s lifestyle. Some people prefer more immediate results, while others value the flexibility of performing part of the treatment at home, gradually. There is no single solution that works for everyone.

Regardless of the selected protocol, all treatments are closely monitored by the clinical team. This monitoring allows the plan to be adjusted whenever necessary, control possible sensitivities, and ensure that the whitening occurs progressively and safely, maintaining the integrity of the teeth and gums.

In-office whitening

Ideal for those seeking faster results and prefer to have the entire process done at the clinic.
– Sessions conducted entirely in the dentist’s chair
– Rigorous protection of gums and soft tissues
– Constant monitoring of sensitivity
– Visible results in a few sessions

Perfect for those who prefer to treat their smile at home, with close support from the Mint team.
– Personalized trays and detailed instructions
– Periodic follow-up at the clinic
– Adjustment of duration and frequency to your sensitivity

Whitening and dental veneers: when to combine treatments

In some cases, whitening is just the first step of a broader dental aesthetic plan. When there are internally darkened teeth, old restorations, or marked differences in shape, dental veneers may be the ideal solution to harmonize the entire smile.

At Mint Clinic, we evaluate with you whether it makes sense to combine whitening and dental veneers, always aiming to achieve a natural, balanced result in harmony with the face.

Resultados que pode esperar do branqueamento

A brighter smile may seem like a detail, but it has a direct impact on how you see yourself and communicate with the world. Many people report feeling more comfortable smiling in photos, meetings, or social moments in daily life.
Whitening can also be integrated into more complex oral rehabilitation or dental aesthetic plans, such as invisible aligners, dental veneers, or implant rehabilitations. The goal is for all elements of the smile to “speak the same language.”

Prices, whitening plans, and payment methods

The cost of whitening varies according to the type of protocol, treatment duration, and case complexity. At Mint, we prefer to be transparent and explain exactly what is included in each plan before any decision.

All values are explained with total clarity, without surprises. We offer phased payment options and integration with more comprehensive treatment plans.

Frequently Asked Questions

Frequently asked questions about whitening at the dentist

Sensitivity may occur in some cases, but it is temporary and controllable. At Mint, we adjust the gel concentration and application time to your sensitivity level and recommend specific products when necessary.

When performed with certified products and supervised by a dentist, whitening is a safe procedure. What can be harmful are over-the-counter products, without control, or inadequate concentrations applied without clinical evaluation.

It depends on factors such as diet, consumption of coffee, tea, red wine, and tobacco. With proper care and, when indicated, maintenance sessions, results can remain stable for several years.

Dental veneers and crowns do not lighten with whitening. In these cases, we evaluate whether it makes sense to whiten natural teeth first and then adjust or replace some restorations to ensure everything is in harmony.

Generally, teeth whitening is only recommended after the completion of permanent dentition. The decision is always made on a case-by-case basis, in consultation, after a complete clinical evaluation.
