Any procedure that lightens a tooth’s color is considered tooth whitening. The stain is either physically removed or the tooth color is lightened chemically to achieve whitening.
LED teeth whitening whitens teeth using an LED (light-emitting diode) and a tooth-whitening chemical, such as hydrogen peroxide.
Americans spend $1.4 billion annually on over-the-counter teeth whitening solutions to get a whiter smile. There is a $3.2 billion global market for cosmetic tooth whitening, including people around the world.
How Do LED Whitening Devices Work?
Users first treat their teeth with a chemical substance that has bleaching capabilities before using LED teeth whitening. The whitening agent is subsequently activated and the chemical reaction is started using blue LED light. 1
When this interaction occurs, the blue light penetrates the enamel and removes any stains that may already be there.
LEDs are more durable and efficient than traditional types of lighting. They do not require a warm-up period before turning on and operating at maximum capacity.
If an LED is used alone, it will not, however, alter the color of your teeth. It functions as a catalyst to quicken the whitening agent’s chemical reaction.
The two types of peroxides that are most frequently used for bleaching are hydrogen and carbamide.
How safe are LED Teeth-Whitening Lights?
For at-home use, LED teeth whitening was created to be secure. According to recent studies, LED teeth whitening is both secure and efficient when used in accordance with the manufacturer’s instructions. 2, 3
When compared to ultraviolet (UV) light, which can cause cell mutation, LEDs are a safer light source. Without the hazards associated with UV light, an LED light accelerates the whitening reaction without mutating cells.
Before bleaching your teeth, consult your dentist. For some people, teeth whitening does not work. Results vary depending on the user’s lifestyle and the reason for their discolored teeth.
Compared to teeth that are brown or grey in color, yellow teeth respond better to LED teeth whitening machine.
LED Teeth-Whitening Kits’ Side Effects
Similar to conventional teeth whitening methods, the most prevalent side effects of LED teeth whitening kits are mild gingival irritation and tooth sensitivity. Three elements that raise the probability of these adverse outcomes are as follows:
- The bleaching agent’s concentration
- The length of the treatment
- The whitening product’s recipe Ignoring the directions provided by the manufacturer
- Tooth sensitivity starts throughout the whitening procedure and can linger for several days. A day after the therapy, gingival discomfort may start and remain for several days.
Susceptibility to tooth demineralization is one of the more serious adverse effects. Overexposure to the bleaching agent is to blame for this. Pulpal injury is a serious adverse effect as well.
All bleaching methods, whether over-the-counter, at-home kits, or at the dental clinic, are transient and call for touch-ups eventually. LED teeth whitening may be worthwhile if your way of living permits you to keep the effects.
Only if you disregard the product’s directions is there a significant danger of adverse reactions. However, see your dentist to learn which LED teeth whitening machine is best for you.
