Getting ready for a special day? Want to appear more youthful? Gave up coffee, red wine, or smoking and wish to get rid of the stained teeth resulting from your former habits?
Whatever your reason for wanting whiter teeth, it's never been easier to have a brighter smile. Multiple options exist to whiten teeth, and some include UV, halogen, and LED lights designed to enhance the whitening process. But do you really need the extra expense of a light? And are the lights safe?
At your convenience at home, you can apply any of the numerous over-the-counter treatments to whiten your teeth. Or your dentist can perform a cosmetic teeth whitening procedure in the office with at-home follow-ups if necessary. It all depends on your budget and time.
The types of treatments include everything from whitening toothpaste to products incorporating teeth whitening lights. There are primarily three types of lights used in teeth whitening:
First up – how it works: The lights must be used in conjunction with a teeth-whitening substance, such as hydrogen peroxide or other whitening agents. After you or your dentist applies the whitening agent to your teeth, targeting the light on your teeth activates the whitener.
Is using light-activation worth it, though? Researchers found that laser, halogen, and LED light-activation produced increased lightening of tooth shade and maintained the lighter shade longer than non-light-activated teeth whitening in a study published in the Journal of Conservative Dentistry. Laser and halogen lights were most effective.
This comes down to you or your dentist using the lights safely.
If not used correctly, UV light is considered a risk. It might cause soft tissue burning, gum irritation, damage to teeth, and increased tooth sensitivity. That's why your dental professionals will take every precaution to protect your teeth and gums when using UV light during a teeth whitening procedure.
For home use, be sure to follow the manufacturer's instructions exactly as written. This entails the length of time to use the whitening agent and the LED light.
If you have questions about teeth whitening lights, have a conversation with your dental professionals about the treatments available. They'll help you decide what's right for you regarding whitening agents and light-activation methods, whether UV laser, halogen, or LED.
