@ncide I think I really lucked out; all three of the dentists were very kind and happy to answer any questions I had, and guided me through several of the procedures they did throughout the day. I had a great time with all three, but I think each has their own merit and advantages. For ortho, I thought that the way the orthodontist knew each of the patients personally was really interesting-- the repeated appointments allow the patient-dentist relationship to really build, and I thought that was pretty cool. The oral surgery I had an awesome time, because I really admired the dexterity and skill required to pull off these procedures. Oral surgery covers a huge variety of treatment and procedure, from tooth extraction to facial reconstruction, and I think that's amazing. Periodontics I knew the least about going into shadowing, but I got to directly observe how oral disease is treated, and that seemed really interesting.
