What Are Teeth Whitening?

Teeth whitening products range from over-the-counter to treatments that require a doctor’s visit. There are several types of teeth whitening products, but all work by removing the natural color of teeth.

There are three primary ways whitening works: by lightening tooth enamel, by darkening stained dentin beneath the enamel, and by bleaching the teeth’s surface layer. Teeth whitening products use one or more of these methods to achieve results.

Tooth whitening products use various light sources such as ultraviolet light, LED lights, or lasers to remove tooth color. Some Whitenix LED teeth whiteners use blue and infrared LEDs which penetrate deep into teeth and break down color molecules. Ultraviolet light exposure is also effective but less efficient so most products combine it with other light sources.

The type of whitener used plays a role in how long the treatment will last and what the final result will be. Over-the-counter bleaches usually work in about two hours but can take up to 12 hours for a noticeable difference. In contrast, professional laser treatments can take around 15 minutes but results last for up to six months.

The Science Behind Teeth Whitening

Teeth whitening is a popular cosmetic procedure that uses bleaching agents to lighten teeth. The process works by breaking down the tooth’s natural melanin pigments, which causes the teeth to become lighter in color.

There are a few different types of bleaching agents available, but hydrogen peroxide is the most popular. Hydrogen peroxide comes in both topical and oral forms and is usually used as a mouthwash or gargle. It works by damaging the DNA of the melanin pigment cells, which leads to their eventual death.

Some people find that teeth whitening kits work better than standalone peroxide products because they contain other ingredients that help to lighten teeth more quickly. These include trays, gels, and sprays that deliver hydrogen peroxide directly to the teeth. Whitening strips also use this type of delivery method, but they are less accurate than kits because they rely on user error to apply the right amount of strip each time.

Types Of Teeth Whitening Treatments

There are a few different types of teeth whitening treatments available on the market today. Nearly all tooth whitening treatments employ one or more of four main methods: light, laser, ultrasound, or radiofrequency.

1. Light-based whitening treatments – This treatment uses devices that emit short-wavelength light (such as lasers) to penetrate the surface of the teeth and break down the deposits of pigment that cause teeth to look yellow or brown. 

2. Laser whitening – This is the most common type of light-based whitening treatment and results in the best overall results. However, it is also the most expensive and requires regular visits to a dentist for maintenance.

3. Ultrasound whitening – This method uses high-frequency sound waves to vibrate the enamel and remove unwanted stains. Ultrasound Whitenings are less time-consuming than laser whitening but less effective than light-based treatments. 

4. Radiofrequency Whitenings – This work by heating up nearby tissue and causing it to contract, which causes bleaching. This type of whitening treatment is becoming increasingly popular as it is more affordable than some other types of white-light treatments and does not require any periodic visits to a dentist. 

While there are several different types of teeth whitening treatments available on the market today, they all have several common features: they work by breaking down deposits of pigment that cause tooth color discoloration; they produce good results with minimal side effects; they typically require only one or two appointments per
