Question

At which if these ages is it most important to visit the dentist regularly

Answer 1

A. 16 years old

Seems like the best answer, since at that age, all of your adult teeth have come in and are at a prime moment for being adjusted. Also your wisdom teeth typically come in at that age as well.

Answer 2

I believe the correct option is A. 16 years old.

Hope I could help! :)
