Dental Phobia I Need To Have A Few Teeth Out But Have A Dental Phobia. Do They Give Gas Anymore?

I need to have a few teeth out but have a dental phobia. Do they give gas anymore? - dental phobia

I am a 38yr old and had dental problems in the past two years. I have many teeth. The only problem is that I have a dental phobia! I wonder whether to continue dentists in the United Kingdom, the gas anaethesia administration? I remember when gas was a kid, but I do not know if they would still be allowed to administer gas today. PLEASE do not suggest to endure the pain of the shot and tell me they have only a few seconds and will be completed. I am by no means an injection! Thanks
