Seoul Songpa Seoul Plus Dental Clinic teeth whitening consultation

My friend said she was looking into teeth whitening.
We went to Seoul Plus Dental Clinic together.

Depending on the original tooth tone
I was told that there is a difference in the degree of brightening after whitening.

The habit of frequently drinking coffee or tea
They said it affects the maintenance period.

I was surprised that you talked more about your lifestyle habits than I expected.
