The answer to the above question is no, the vast majority of dental professionals will not use laughing gas (nitrous oxide) as a matter of course when they need to pull out your teeth.
But that’s not to say you can’t ask your dentist for nitrous oxide to sedate you, especially if you need help with a dental fear or are anxious of the dentist, or if you are having all of your teeth extracted in readiness for getting dentures.
But at the end of the day, the usual dental anesthetic is very fit-for-purpose, and if your concerns are about feeling pain, then you need not worry at all.
Furthermore, these days it doesn’t take long to pull teeth out so it will be over before you realize it.
All you should feel is a little slight pressure and a bit of pulling and tugging.
