Teeth whitening – safe treatments for a smile up to 5 shades whiter

Professional teeth whitening is one of the most requested cosmetic dental treatments – and for a good reason. In just one hour, teeth can become up to 5 shades lighter, creating a brighter, fresher, and healthier smile. But before you decide on this procedure, it’s important to understand the difference between in-office whitening with a lamp and at-home whitening with trays and gels, as well as the entire process – from consultation to final results.

What types of teeth whitening are there?

The two most effective and commonly used methods are:

1. In-office whitening with a lamp, using a gel activated by UV light.

2. At-home whitening using custom-made trays and gel.

Both methods are safe and deliver excellent results but differ in speed and application.

 In-Office Whitening with a Lamp – How Does the Procedure Work?

The lamp whitening procedure takes about 1 hour and 30 minutes and is performed exclusively in the dental office under professional supervision.

The process includes:

1. Examination and preparation
   The dentist evaluates the condition of the teeth, gums, enamel, fillings, or crowns. Professional cleaning and polishing are performed.

2. Consultation and contraindication check
   Not recommended for pregnant or breastfeeding women, and people with melanoma, diabetes, or heart conditions.

3. Protection and gel application
   A 32% hydrogen peroxide gel is applied and activated with a UV lamp. Protective pads, glasses, gingival barrier, and retractors are used. The gel acts for 15 minutes, and the process is repeated 3–4 times, depending on sensitivity.

4. Possible sensitivity
   Patients may feel sharp, fleeting pains (intensity 0–5), but this is temporary and individual.

5. Post-treatment care
   For 7–10 days after whitening, avoid:

   • Dark beverages (tea, coffee, wine)

   • Staining foods

   • Mouth rinses with chlorhexidine
     Use a whitening toothpaste and apply lip balm regularly.

6. Before and after photos
   Documentation of shade change and results is done.

 At-Home Whitening – How Does It Work?

In this method, the patient uses special trays at home, made in a dental lab from an impression or digital scan of their teeth. The gel used contains 16% carbamide peroxide.

The process includes:

1. Examination and impressions
   Same as with lamp whitening – initial assessment of teeth and shade.

2. Tray fabrication
   The impression or scan is sent to the lab to create personalized trays.

3. Home use
   Trays are worn for 5 hours a day for 7 days. Before use, brush your teeth, carefully apply the gel, and clean and dry the trays afterward.

4. Monitoring and check-up
   The dentist monitors progress, and a final control and photo documentation are done.
   As with lamp whitening, avoid dark foods and drinks during treatment and for 7–10 days afterward.
