Everything About Teeth Whitening — Methods, Prices, and Results

Teeth whitening is one of the most popular procedures in cosmetic dentistry. Coffee, tea, smoking, and certain foods change the color of the teeth over time. Professional whitening procedures can make teeth several shades whiter.

In-office whitening is the most effective method. The dentist applies a high-concentration hydrogen peroxide or carbamide peroxide gel, sometimes activating it with an LED or laser light. The process takes 45–60 minutes and produces a noticeable result in a single session. At-home whitening, on the other hand, is carried out with custom trays prepared by the dentist and a lower-concentration gel — results become visible within 1–2 weeks.

Side effects are generally temporary. Tooth sensitivity and gum irritation are the most common side effects and usually subside within a few days. Whitening is not suitable for everyone — it is not recommended for pregnant women, those under 16, or people with serious dental disease.

To maintain the results, patients should avoid staining foods, brush regularly, and have a professional cleaning every 6 months. With the GateDent treatment module, you can track whitening procedures, send reminders to patients, and record the results.
