There are several distinct levels of sedation provided to dental patients, but not all dentists are sure what situation calls for specific methods and when to call in the big guns – general anesthesia. 

• Local Anesthesia is administered via injection or topical and typically ends in -caine. 
• Minimal Sedation leaves the patient relaxed and awake, and able to respond. 
• Moderate Sedation often provides a dream-like state and although the patient is awake, they may not remember the procedure. 
• Deep Sedation is barely awake but can be roused with stimulation when necessary. 
• General Anesthesia (GA) results in complete unconsciousness and amnesia. 

Most of the levels involve the use of nitrous oxide, enteral sedation, or intravenous (IV) administration. IV sedation can be used to provide anywhere from minimal to deep sedation levels as well as general anesthesia. However, all forms of sedation and GA have different qualifications and legal requirements based on state regulations.
