Professional Teeth Whitening · Eixample, Barcelona
Professional Teeth Whitening in Barcelona
Teeth whitening at COSMOGLOW begins with a personalised dental assessment, so we can check your gums, teeth, existing restorations and starting shade before recommending treatment. Our approach is designed for a brighter, natural-looking smile, with oral health and realistic expectations at the centre.
What professional whitening involves
Whitening planned around your teeth, gums and expectations.
Professional teeth whitening is not a one-size-fits-all treatment. The right approach depends on your oral health, your starting shade, your sensitivity, your habits and the type of restorations you may already have.
At COSMOGLOW, we assess your mouth before recommending whitening. If your gums need attention, if a professional clean is advised first, or if whitening is not suitable for your case, we will explain this clearly before any treatment begins.
Is whitening right for you?
A personalised assessment comes first
Whitening can be a good option for many patients, but it should always be planned around the condition of your teeth and gums. During your assessment, we explain what is appropriate for your case and what kind of result you can realistically expect.
Healthy teeth and gums
Whitening is usually considered when your teeth and gums are in good condition. If we detect inflammation, cavities or gum concerns, these may need to be addressed first.
A professional clean may be recommended
In many cases, dental hygiene is advised before whitening so the treatment starts from a cleaner and healthier baseline.
Not suitable for every case
Whitening may not be appropriate for some patients, including those with untreated dental issues, certain restorations, high sensitivity or other specific situations. We will advise you honestly.
Your starting shade matters
Whitening results vary from person to person. We assess your starting colour and expectations so the plan stays realistic and natural-looking.
Our whitening philosophy
A brighter smile, planned with oral health in mind.
Natural-looking whitening
The goal is not an artificial white shade. We plan whitening around your teeth, your features and what looks balanced for your smile.
Oral health before aesthetics
Your gums, enamel, restorations and sensitivity are reviewed before treatment is recommended.
Combined treatment approach
We focus on a combined whitening protocol, bringing together professional guidance and at-home support with custom trays when appropriate.
Clear maintenance guidance
We explain how to care for your result, what habits can affect colour over time and when future review may be useful.
Combined whitening
A professional whitening plan with guided at-home support.
At COSMOGLOW, teeth whitening is approached as a guided dental treatment, not a quick cosmetic add-on. After your assessment, we explain whether combined whitening is suitable for you and how each part of the process fits into your plan.
Assessment and suitability
We first check your oral health, sensitivity, restorations and expectations before confirming whether combined whitening is appropriate.
Custom trays when appropriate
Intraoral scanning may be used to support the creation of custom trays for the at-home part of the combined protocol.
At-home instructions explained
Your treatment is explained clearly by the dental team, including how to use your at-home whitening support without needing to follow generic advice.
Maintenance and follow-up guidance
We explain how to care for your smile after whitening, which habits may affect colour over time and when a future review may be useful.

What patients say about their dental care at COSMOGLOW
Questions before whitening
Common questions about teeth whitening.
A professional dental clean is standard clinical practice before any whitening treatment. It helps the whitening gel act more evenly and ensures your teeth are in the right condition before treatment begins. If you have not had a recent hygiene appointment, your clinician may recommend scheduling one first.
Some patients experience mild sensitivity during or in the days following treatment. This is a normal response and typically resolves within a few days. If you already have sensitive teeth, this will be discussed at your assessment and taken into account when recommending the most appropriate option.
Professional whitening is most effective on surface staining caused by food, drink, ageing and tobacco. It is less effective on some types of internal discolouration, such as staining caused by certain medications. It also does not change the colour of crowns, veneers or composite bonding. Your clinician will assess your situation and explain what is realistically achievable.
Results typically last between one and two years, although this varies depending on your lifestyle, dietary habits and oral hygiene routine. Avoiding strongly pigmented foods and drinks and maintaining good dental hygiene can help extend your results.
In-clinic whitening is carried out directly by your dental clinician at the practice. Home whitening uses custom-fitted trays and a prescribed gel that you apply yourself over a period of time. The combined option uses both. After your assessment, your clinician will recommend the format that best suits your teeth and your goals.
Professional whitening carried out under clinical supervision is a well-established dental procedure. At COSMOGLOW, every whitening treatment is preceded by a clinical assessment and follows a supervised protocol from start to finish. As with any dental procedure, not all patients are suitable candidates, which is why the assessment stage is essential.
