That's weird. Why not? The process of sedation should be the same regardless of the procedure. You may want to contact your local dental society and find out which dentists in your area do sedation dentistry.
i am very nervous of dentist 2 have been told i will go in hospital 2 get teeth removed how they go about this i dont know hopefully i want see it.
If you go to a hospital, they may do it under general anesthesia, which is basically what you undergo when you have heart surgery, etc.
