When applied correctly by professionals, UV light is generally safe and effective for teeth whitening. However, misuse or overexposure can lead to potential risks such as tooth sensitivity or gum irritation.
What is UV Light and Its Role in Dentistry?

- Completion: The process usually takes 30-60 minutes and may require multiple sessions for optimal results.
