Teeth whitening has become one of the most requested cosmetic treatments worldwide. The search for a whiter, brighter smile goes beyond appearance: it reflects confidence, security, and personal well-being. However, before choosing a method, it is essential to understand the different types of whitening, as well as their risks and considerations.

1- In-office whitening
This procedure is performed by a dentist using high-concentration whitening agents. The process is often accelerated with LED or laser light. The main advantage is speed: results are visible in one or two sessions. However, temporary tooth sensitivity may appear.

2- At-home whitening
The dentist provides custom trays and a peroxide gel for home use, under professional supervision. It is a progressive treatment that requires discipline and consistency. Although results take longer, the outcome is a more natural and uniform color.

3- Over-the-counter products
Whitening toothpaste, adhesive strips, or mouth rinses are widely available. Their effect is usually limited and they are best used as a complement to professional treatment. Overuse may wear down the enamel.

Risks and considerations
a) Tooth sensitivity: Common but usually temporary.
b) Gum irritation: May happen if the whitening gel touches the soft tissues.
c) Not for everyone: People with cavities, extensive restorations, or gum disease should avoid whitening until dental problems are resolved.

Which option to choose?
The decision depends on oral health, budget, and expectations. In-office whitening is perfect for those seeking quick results; at-home treatment provides a gradual, natural change; and commercial products can help maintain results but should not replace professional care.

If you are considering this treatment, visiting a qualified dentist is the safest choice. You can read more at the Colgate Oral Health site.
