Teeth Whitening in Madrid
What is teeth whitening?
Teeth whitening is an aesthetic treatment that lightens the colour of your teeth using professional whitening agents, such as hydrogen peroxide or carbamide peroxide, applied under clinical supervision. Unlike pharmacy products or home remedies, professional teeth whitening is safe, effective and personalised: it is adapted to your enamel, your starting shade and your tooth sensitivity.
At MAG Dental Madrid we whiten in the clinic with Philips Zoom, one of the most advanced LED whitening systems: up to 8 shades whiter in a single 45-minute session, with little to no sensitivity.

Who is teeth whitening for?
Teeth whitening is recommended for:
- People with yellowish or darkened teeth.
- Patients with stains from coffee, tea, wine or tobacco.
- Smiles that have dulled over time.
- People who want a more attractive smile without invasive treatment.
- Patients with good oral health (no decay or active gum disease).
Before treatment, a check-up is essential to confirm that teeth whitening is the best option in your case.
"The main advantages of teeth whitening are the quick aesthetic improvement of your smile and its affordable price."
- Dr. Alejandro Prieto
Types of teeth whitening
These are the most common types of teeth whitening:
In-clinic whitening (LED light – Philips Zoom)
Done in the clinic with an LED lamp, it gives immediate results in a single session. Ideal if you want a fast, controlled change.
At-home whitening
Done with custom-made trays and a professional gel, always under dental supervision. It gives gradual, very natural results.
Combined treatment
Combining in-clinic and at-home whitening is the most effective option for a long-lasting, stable white.

Benefits of teeth whitening
- Immediate improvement in the look of your smile
- Conservative treatment: no drilling or reshaping of teeth
- Visible results from the first session
- Safe when properly indicated
- More confidence when you smile
Teeth whitening with Philips Zoom: the most advanced technology
At MAG Dental Madrid we perform in-clinic whitening with Philips Zoom, one of the most advanced professional whitening systems and the most patient-requested whitening brand. It combines a whitening gel with an exclusive LED light that speeds up and boosts the result, for a visible change in one visit.
Results in a single session
- Up to 8 shades whiter in about 45 minutes, in one in-clinic session.
- Carried out in 15-minute cycles under the LED lamp, after a short preparation.
- 99% of patients feel little to no sensitivity, thanks to adjustable light intensity.
- Over 50% better results than other in-office whitening treatments, measured immediately, one week and 30 days after.


How Philips Zoom whitening works, step by step
- Assessment and shade record. We check that your teeth and gums are healthy and record your starting shade so you can compare the result.
- Professional cleaning. We remove plaque and surface stains so the gel works evenly on every tooth.
- Gum and lip protection. We isolate your gums and lips with a protective barrier so the gel only touches the enamel.
- Whitening gel. We apply the Philips Zoom gel to the visible surface of your teeth.
- LED light cycles. The Zoom lamp activates the gel in 15-minute cycles (about 45 minutes in total), adjusting the intensity for your comfort.
- Final shade and care. We compare the new shade with the starting one and apply a desensitising treatment if needed.
- Maintenance at home. We give you aftercare advice and, with the combined treatment, custom trays to keep your result for longer.
Why we chose Philips Zoom
We only use systems that give predictable, natural-looking results. Philips Zoom lets us whiten safely in one visit, control sensitivity and combine the session with at-home trays when you want a longer-lasting result. Every aesthetic treatment is led by Dr. Alejandro Prieto, surgeon, medical director and founder of MAG Dental Madrid.
Downsides and possible side effects
Teeth whitening has a few things to keep in mind:
- It can cause temporary tooth sensitivity
- It does not whiten fillings, crowns or veneers
- It needs maintenance to keep the colour
- It is not suitable in every case (for example, very deep stains)
Proper diagnosis and professional follow-up keep these effects to a minimum.
How long does teeth whitening last?
How long teeth whitening lasts depends on several factors:
- Your habits (smoking, coffee, red wine)
- Oral hygiene
- The type of treatment
In general, results can last between 1 and 3 years, especially if you follow your dentist’s advice and do maintenance sessions when needed.

Frequently asked questions
How much does teeth whitening cost in Madrid?
In-clinic whitening with Philips Zoom costs from €300 to €450, at-home whitening from €250 to €350 and the combined treatment from €450 to €600. You get a written quote after your assessment and can finance the treatment over up to 60 months.
What is the best way to whiten teeth?
The best way is a professional treatment supervised by a dentist. In-clinic whitening with Philips Zoom, alone or combined with at-home trays, gives better and safer results than pharmacy products and reduces the risk of sensitivity or damage.
What are the downsides of teeth whitening?
Some patients notice temporary sensitivity in the first days. Whitening is not permanent and coffee, red wine or tobacco can affect the result. It also does not change the colour of crowns, veneers or fillings; if you have them, we plan the shade so everything matches.
How many sessions of teeth whitening do I need?
With Philips Zoom, one in-clinic session of about 45 minutes is usually enough for a clear change of up to 8 shades. Some patients add at-home trays to optimise and maintain the result.
How long does teeth whitening last?
Results usually last between 1 and 3 years, depending on your habits and maintenance. Avoiding staining food and drinks and keeping good oral hygiene helps the result last longer.
Does Philips Zoom teeth whitening hurt?
No. 99% of patients feel little to no sensitivity, and we adjust the light intensity for your comfort. Any mild sensitivity, usually to cold, disappears within a few days.
What happens if I eat staining foods after teeth whitening?
Avoid food and drinks with strong colour (coffee, red wine, tea, dark soft drinks) for at least 48 hours. Having them during that time can stain your teeth again and shorten the result.
How do I get rid of yellow teeth?
Professional teeth whitening is the most effective way. A dental cleaning and good hygiene prevent surface stains, but when the colour of the tooth itself has changed, whitening is the most effective and safe treatment.
