Concern) Teenager teeth whitening

Is there a minimum age for teeth whitening procedures?

Have you ever consulted about teeth whitening procedures for middle and high school students?

For some reason, I don't think procedures will be recommended for adolescents who are still in their growth phase due to aesthetic reasons.

I wonder if there are other procedures that teenagers can undergo.

Is it okay to use whitening toothpaste if the procedure is still too difficult?

I'm worried about whether there are any harmful ingredients for growing children.
