Home whitening is one of the most popular aesthetic treatments for those who want a brighter smile without having to disrupt their routine.
The treatment is carried out gradually and gently, in the comfort of your own home, but always under the supervision of your dentist.
It is important not to confuse professional home teeth whitening with do-it-yourself methods (e.g., baking soda) or the various whitening toothpastes or over-the-counter products, also available online: only a treatment prescribed by a professional in fact guarantees effective and, above all, safe results.
Home teeth whitening: what it’s all about
Home teeth whitening is a painless professional procedure to lighten the color and mitigate stains and discolorations, following a personalized protocol.
The treatment involves the application of specific whitening gels inside custom-made transparent templates.
Unlike home remedies or over-the-counter whitening products, this approach uses active ingredients at a controlled concentration, not damaging tooth enamel and minimizing the risk of sensitivity and irritation.
The goal is not to “whiten teeth in a day” but to lighten them harmoniously, respecting tooth structure and restoring their natural color.
Home whitening costs vary by treatment type and duration, so an in-office evaluation is always recommended, with a clear and personalized estimate.
How home teeth whitening works
Home teeth whitening relies on the action of peroxide-based gels, a substance that acts on the pigments responsible for discoloring teeth.
In simple terms, the treatment works like this:
- the gel penetrates the surface layers of the enamel
- Breaks down the molecules that cause the stains
- Contributes to gradual brightening of tooth color
The effectiveness of the result depends on both the time of application and the consistency with which the dentist’s instructions are followed.
The course usually involves:
- dental examination with initial assessment
- Fabrication of customized template from impressions taken with 3D intraoral scanner
- Delivery of the home kit, complete with gel to be applied inside the mask
- Daily use for a period determined by clinical evaluation
- Periodic studio checks to monitor progress.
Home whitening with custom-made masks: why they make a difference

The real strength of professional home whitening are the custom-made templates, designed to precisely fit each patient’s mouth.
The custom-made fit ensures:
- An even distribution of the gel on all tooth surfaces
- increased comfort during application
- better protection of the gums
Typically, the masks are worn for a few hours a day or overnight, for a period ranging from 1 to 3 weeks, depending on the dentist’s instructions.
Compared with standard masks, custom-made masks allow for better results and an overall more comfortable experience.
How long does home bleaching last and when do you see results
The duration of hometeeth whiteningdepends on several factors:
- starting color
- type of dyschromia
- eating habits and lifestyle
- consistency in application
The first improvements are often visible after only a few days, while the full result is appreciated at the end of the treatment.
With proper maintenance, the effect can last a long time, even beyond 24 months, especially if supported by periodic checkups.
For whom home teeth whitening is indicated
Home tooth whitening is indicated for:
- Patients with mild to moderate dyschromia
- Those who want a natural result in a non-invasive way
- Those who prefer to manage treatment from the comfort of home
Critical is the initial dental evaluation to determine whether the treatment is suitable and safe.
When home bleaching is a choice to avoid
However, home bleaching is not always indicated.
In fact, it may not be recommended in the presence of:
- Untreated tooth decay or gum inflammation
- Visible restorations (fillings, veneers, crowns)
- Deep discolorations or spots that cannot be bleached
- marked tooth sensitivity
In these cases, the dentist can propose customized alternatives that are better suited to the clinical situation.
How to maintain the results of home bleaching over time
To maintain and prolong the results of home whitening, it is essential to follow proper daily oral hygiene and limit consumption of smoking, coffee, tea, red wine and other pigmented beverages. Periodic checkups and professional hygiene sessions also play a key role, as they allow the color of teeth to be monitored and any whitening recalls to be evaluated if necessary.
