Sedation treatment is a safe option for those who don’t like having dental treatment for whatever reason, for those who have a severe gag reflex and for those with a history of a previous bad experience.
During sedation treatment you breathe on your own, this is not like hospital anaesthesia where a machine breathes for you. As such it is a very safe form of treatment.
The sedative medication calms you down and produces an amnesic effect so you won’t remember much after the treatment.
Your dentist will numb your teeth as they routinely do with injections once you are nice
