Because endodontists specialize in root canals, they’re equipped to only perform root canals all day, every day. But, not all abscesses are the same! While similar procedures are repeated throughout the day, your patient’s stories and situations will vary. It’s rewarding work to help patients recover from horrendous mouth pain and reclaim their smiles. As an assistant, you’ll be supplying the dentist with the tools needed to complete the root canal, applying suction when needed, helping the dentist fit crowns, and setting up and cleaning the rooms.
