Teeth whitening is one of the most popular cosmetic dental procedures, but the options can be confusing: professional whitening at the dental office, or a kit bought at a pharmacy or supermarket?
Professional in-office whitening
Whitening performed by a dentist uses a higher concentration of whitening agent, is applied with gum protection and under professional supervision, and usually delivers visible results in a single session. Your dentist can also identify any underlying issues (such as cavities or sensitivity) that should be addressed first.
At-home kits
Over-the-counter kits contain a lower concentration of the active whitening ingredient, which is why they require more time and repeated use to achieve visible results. Without professional guidance, there's a higher risk of uneven results or gum irritation.
How long the results last
The duration of results depends on your habits (coffee, wine, smoking) as well as the method used. Generally, professional whitening lasts longer because the results are more even and stable from the start.
Before you decide
Regardless of the method, a dental check-up before whitening is important — there are cases (such as pregnancy, severe sensitivity, or existing restorations) where whitening should be postponed or adjusted.
At DentLux Clinic, we offer professional fläsh® whitening under the guidance of our dentist — book an appointment for an assessment, and we'll recommend the best approach for your case.
