it sounds like you don’t like something that you’ve heard or like there may be a trust issue between you and your son’s orthodontist. i think a second opinion is always a good idea in that case.
my orthodontist wants to remove some of my son’s teeth for a better orthodontic result. should i get a second opinion? . the other option i was given included having surgery for his jaw. we could just get braces without doing any preparation beforehand. but then he may need braces again -- or surgery -- as an adult.
