More and more people are interested in teeth whitening. No wonder: it is an aesthetic treatment that can transform a smile in a very short time. However, there are many doubts surrounding the process: if it really works, how long it lasts, if it can damage teeth or if it causes sensitivity. Below, we solve everything you need to know from a clinical and realistic approach.

What exactly is teeth whitening?

Tooth whitening is a procedure that uses peroxide-based gels to lighten the color of teeth several shades. Its function is to remove internal stains and pigmentations accumulated in the enamel over time, without affecting the tooth structure.

Before performing it, it is advisable to have a good professional dental cleaning, since it removes external stains, tartar and plaque that could interfere with the result.

Types of bleaching

• In clinic: Application of high concentration gel activated with LED light. Fast and visible results.

• At home: Use of customized splints with gel of lower concentration. More gradual.

• Combined: A clinical session plus outpatient treatment. It usually offers the best results in balance between efficacy and durability.

What if I also want to improve the shape or position of my teeth?

Whitening acts on the color, but not on the shape or alignment. In cases where a more comprehensive aesthetic improvement is sought, other solutions such as dental veneers or even invisible orthodontics may be necessary.

Is it a safe treatment?

Yes, as long as it is performed under professional supervision. Whitening does not damage the enamel when clinical products are used and applied following proper protocols. What can cause problems is the indiscriminate use of online products, abrasive pastes or uncontrolled home methods.

Improperly applied, these products can lead to halitosis, enamel wear or chronic tooth sensitivity.

Conclusion

Teeth whitening is an excellent option to improve the aesthetics of your smile quickly and safely. Like any treatment, it requires a previous professional assessment and certain care to ensure a good result and maintain it over time.

The key is to understand that each smile is unique, and not all treatments work equally well for everyone. The most important thing is to look for a natural, lasting and healthy result.
