Teeth whitening machines normally have a compact design and are very convenient. This product can produce light rays that can activate the whitening agent so that they will penetrate deep into the teeth and make the teeth whiter.

In fact, the mechanism of the teeth whitening machine is similar to when you go to the dental clinic to have laser and light teeth whitening methods.

The bleach (whitening agent) will be put into the tray and then placed on the teeth. Then use a teeth whitening machine that releases light to activate the whitening agent in a short time.

The light of the teeth whitening machine will activate the specially formulated whitening agents to remove stains and the teeth whiter quickly (usually within 5 – 15 minutes).

When buying a teeth whitening machine, it will usually come with teeth whitening paste. This kind of paste is similar to the teeth whitening agent in dental clinics or other common pastes available on the market nowadays. Therefore, you can replace this paste with other whitening agents because you can achieve the same result with the teeth whitening machine.

If you use the teeth whitening machine correctly and follow the instructions, this method will still be safe for the body and help you achieve the result you wish. However, it is very difficult to ensure that the correct amount of whitening agent is in the whitening tray to avoid spilling on the gums.

Because the gums adhere to the roots of the teeth, when the whitening agent covers the entire tooth surface, it is also likely to touch the gums.

When using at-home teeth whitening methods and teeth whitening machines, you cannot isolate the gums while wearing a whitening tray by yourself. Gums that are constantly affected by the whitening agent will gradually become sensitive, irritated, and burning in the long run, which can cause serious gum diseases.

Besides, you must find a reputable place to buy a genuine teeth whitening machine and avoid buying fake products. Instead, you may lose money for nothing but white teeth are nowhere to be seen.
