Will i need anesthesia or laughing gas to get two back teeth removed?

Yes local anesthesia: Local anesthetics are commonly used to numb the teeth that are being worked on, regardless if your getting a cavity filled or a tooth pulled or extracted. Laughing gas or nitrous oxide can be used in conjunction to help make you more comfortable or relaxed for any dental procedure. This is used if you're particularly anxious about having the procedure done but is certainly not essential to have.

Yes: You will most likely require a local anesthetic for the removal of two posterior teeth. The nitrous oxide or laughing gas would be an option as a type of mild analgesic.

Depends: 2 back teeth may include a wisdom tooth. Often patients have 2 teeth extracted with only local anesthesia. Laughing gas can help patients relax somewhat. Sedation is a great option if you are very apprehensive.

No: Most teeth extractions can be done under local anesthesia with a cooperative patient. If there are especially impacted teeth then some sedation might be indicated. It is rare that a full general anesthetic would be needed for dental extraction. If you have concerns please contact your dentist and discuss these fears with him. Procedure is very safe. Good luck.
