Laughing Gas Not Affecting Me

[HIGH NOOT]

So I remember 1 time when I went to the dentist to get a tooth out (the tooth's roots weren't dissolving), and when the put the watermelon flavored laughing gas on, for some reason literally nothing happened, I wasn't feeling any different or loopy I was just acting normal, and after that day I was wondering if it was something to do with the laughing gas they used or maybe something else, does anyone know why I wasn't affected?

Laughing gas does not make you laugh literally. This nitrous oxide just makes you more relaxed, so you would not be nervous while you are in the dentist's chair.
