What's the difference between an orthodontic dental clinic and a general dental clinic?

I'm looking for a good orthodontist, and I'm wondering if it's better to go to a place that specializes in orthodontics.

Since orthodontic treatment takes a long time, I think the initial diagnosis is important, but ongoing management is also crucial.

Should I check if a good orthodontist personally examines the tooth movement status at every visit?

The appointment intervals and whether they can see you immediately in emergencies are also surprisingly important, right? ㅎㅎ

For those who have chosen a good orthodontist, what criteria did you use for comparison?
