What is the
difference between Sedation and General Anaesthetic?
Sedation and general anesthesia are both used in medical procedures to help patients feel comfortable and reduce pain, but they differ in their effects and levels of consciousness.

Level of Consciousness
Dental Sedation
With dental sedation, the patient remains conscious or semi-conscious throughout the procedure. They can respond to verbal commands and maintain their protective reflexes such as coughing and swallowing
General Anesthesia
In contrast, general anesthesia induces a state of complete unconsciousness. The patient is not aware of their surroundings and does not respond to external stimuli.
Administration
Dental Sedation
Sedatives can be administered through various routes such as inhalation (nitrous oxide), oral ingestion (oral sedatives), or intravenous (IV sedation).
General Anesthesia
General anesthesia is typically administered intravenously or through inhalation. It requires precise dosing and continuous monitoring by an anesthesiologist or a dentist with specialized training.
Depth of Sedation
Dental Sedation
Sedation in dentistry ranges from mild to moderate, inducing a relaxed and calm state while allowing the patient to maintain control of their breathing and reflexes.
General Anesthesia
General anesthesia results in a deep and complete loss of consciousness, suppressing the central nervous system to the point where the patient cannot feel pain or respond to stimuli.
Risks and Complications
Dental Sedation
Dental sedation carries minimal risks when administered by trained professionals. However, there may be potential side effects such as drowsiness, nausea, or temporary memory loss.
General Anesthesia
General anesthesia involves greater risks due to the profound suppression of vital functions. Complications can include respiratory depression, cardiovascular instability, allergic reactions, and adverse drug interactions. Therefore, it requires meticulous monitoring and specialized training to manage potential emergencies.
Suitable Procedures
Dental Sedation
Dental sedation is often used for minor to moderate procedures such as fillings, extractions, or root canals, especially for patients with dental anxiety or phobia.
General Anesthesia
General anesthesia is reserved for more complex or extensive dental procedures, such as wisdom teeth extraction, jaw surgery, or procedures on very young children who may not tolerate treatment otherwise.
