Why do you gas to get a wisdom tooth out?

Wisdom teeth do not always require laughing gas or another form of sedation to be extracted. The decision to use sedation is made by the dentist or oral surgeon based on the complexity of the procedure, the patient's anxiety level, and personal preference.

Wisdom teeth are typically extracted when they are impacted or causing discomfort. Impacted wisdom teeth are those that are unable to fully emerge from the gum due to lack of space. This can cause pain, swelling, and infection.

When a wisdom tooth needs to be extracted, the dentist or oral surgeon may recommend the use of laughing gas, also known as nitrous oxide, or other sedation options to help the patient relax during the procedure. Laughing gas is a mild sedative that helps reduce anxiety and discomfort, and it is often used in combination with local anesthesia to numb the area around the tooth being extracted.

Overall, the use of gas or other forms of sedation for wisdom teeth extraction is meant to ensure that the patient feels comfortable and relaxed throughout the procedure, regardless of the complexity or duration.
