Difference between laser tooth whitening and cold light tooth whitening

1, laser tooth whitening

Because there is high heat in the irradiation process, teeth will be dehydrated, which will also have a certain impact on sensitive gums. More importantly, the teeth after laser whitening will appear unnatural white due to dehydration.

2, cold light whitening teeth

The high-heat cold light produced without laser irradiation will not stimulate sensitive teeth, and the whitening teeth will present a natural crystal white color. But as a new technology, with these advantages, cold light tooth whitening will be more expensive than traditional laser tooth whitening, and the validity period will be about two years.
