Purpose: Loosens teeth from the periodontal ligament to make extraction easier and reduce tissue damage 

How it's used: The elevator is rocked and cut against the tooth, rather than lifted and pried 
Features: A thin, sharp blade cuts the periodontal ligament, and the unique handle shape reduces the force on the tooth
