Will laughing gas make me tell my secrets & anxious fears?

Looking for ways to prevent if i ever need to get on laughing gas… been having some terrible headaches, jaw pain, havent seen a dentist in 5 years, afraid i have an infection although my teeth feel fine, but they have small brown in the tooth.

Im thinking of going to the dentist soon if any of this is tooth related. But im nervous if they’ll have to do something like laughing gas.

Sometimes i get very anxious thinking ill say something that really bothers me deep down, like my past. Anyone have experiences with this? Or any remedies to make laughing gas high a quick fade?
