What are some of the most common dentist sedation techniques?

The 3 most common forms of sedation on offer are:

Inhalation sedation (also known as “laughing gas”, “happy gas”, nitrous oxide, “gas and air”, relative analgesia)

Oral sedation (anti-anxiety pills or a liquid)

Intravenous (IV) sedation (drugs administered into the blood-stream through a vein – that’s what “intravenous” stands for)

I have not Had any of these but I am really interested as I really want to go to the dentist but cannot bring myself to because I am such a coward! I do not know that the sedative pill would work on me but I have heard very good things about the 'laughing gas' is very effective, it is the case that you know what is going on but you really don;t care! That will do for me!

Inhalation sedation, Oral sedation & Intravenous (IV) sedation these are mainly sedation techniques:

I know about these techniques but I must say that when I have asked for anything I have always ben talked out of it. I don't know why. I once was going to have a tooth out under GA in the dental hospital and the dentist there talked me out of it. I must admit I did admire the way he managed to get me to fee very confident in him and it was a doodle. I am more worried about fillings and stuff and would like to have sedation for that.
