What professional teeth whitening is

Professional whitening is lightening the enamel by several shades under a dentist's control. Unlike home pastes and folk methods, clinical whitening gives a noticeable, predictable result and, most importantly, is done safely — protecting the gums and monitoring the enamel.

Why enamel darkens

Tooth colour changes for various reasons:

  • coffee, tea, red wine and other staining products;
  • smoking;
  • age-related enamel changes;
  • insufficient hygiene and plaque;
  • some medications and individual factors.

Part of the darkening is removed by professional cleaning, part by whitening. The doctor decides what suits you after an exam.

Types of whitening: in-office and at-home

There are two main approaches. In-office whitening is done in the clinic in one visit — a special gel is activated by a lamp and the result is visible immediately. At-home whitening uses custom trays and gel that the patient uses at home as prescribed. They are often combined for a lasting effect.

How whitening works in the clinic: stages

  • Exam and preparation. The doctor checks the teeth and gums and, if needed, does tooth treatment and professional hygiene.
  • Protecting soft tissue. The gums are isolated so the gel doesn't irritate them.
  • Applying and activating the gel. The whitening compound is applied and activated by a lamp.
  • Assessing the result and care recommendations.

Is it painful and safe for enamel

Professional whitening under a doctor's control is safe for enamel. Sometimes temporary sensitivity appears after the procedure — this is normal and passes within a few days. It is important that a specialist performs whitening: aggressive DIY methods can harm enamel and gums.

How long the effect lasts and how to keep it

The result usually lasts from a few months to 1–2 years, depending on diet, habits and care. To keep it longer:

  • limit coffee, tea, wine and other staining products;
  • quit smoking;
  • brush twice a day;
  • have professional hygiene every 6 months.

Who whitening is not suitable for

Whitening is not recommended in some conditions: pregnancy, significant gum disease, badly damaged enamel. If the colour is strongly changed or there are chips, veneers sometimes look more aesthetic. The doctor chooses the exact solution. Book a consultation.
