1. What is nitrous oxide, and why do dentists use it?
Nitrous oxide, also known as "laughing gas," is a colorless, odorless gas used by dentists to help patients relax during dental procedures. It works quickly to ease anxiety without causing full sedation.

2. Is nitrous oxide safe?
Yes, nitrous oxide is considered safe when administered by trained dental professionals. The effects wear off quickly once the gas supply is stopped, and it has minimal side effects.

3. How will I feel under nitrous oxide?
Most patients feel calm, light-headed, or slightly euphoric. Some experience tingling in the arms and legs. You remain conscious and can respond to the dentist’s instructions.

4. Can anyone use nitrous oxide?
Most people can, but those who are pregnant, have certain respiratory conditions, or vitamin B12 deficiencies should consult their dentist first.

5. How long do the effects last?
The effects wear off within minutes after the gas is stopped, allowing you to resume normal activities soon after the procedure.
