Like you, my gums are dark red and pig liver.

My gums are thick.

Later, I saw an introduction from a doctor in Taiwan Province Province on the Internet.

The doctor's name is Huang yihao

It is said that water laser can be used to whiten gums.

Because I just have time to go to Taiwan Province Province.

Dr. Huang Yihao told me

Gums turn black because of the precipitation of melanin.

Gums can be removed by water laser.

Reduce the part of melanin precipitation

So it will become redder and more tender.

And it can also solve the problem of thick gums by the way.

Dr. Huang Yihao is a professional doctor who uses water laser in Taiwan Province Province.

Because I once saw a news report about him in Taiwan Province Province on the Internet.
