Sedation and general anaesthesia are both possible. The time for the drugs to get out of your body are if anything longer with sedation but the CAA will impose the same grounding time. In practice after sedation you will not get that groggy feeling and be able to go home after an hour or so
Sedation does not provide pain relief so the dentist will still need to use local anaesthetic injections. The sedation removes anxiety making the injections and the operation more bearable. The injections will provide pain relief for some hours afterwards
The choice is really yours. General means a hospital admission so there may be a wait.
One word of caution. Sedation needs the same skills, perhaps more skill, than a general anaesthetic. Insist it is given by an anaesthetist who is an NHS consultant. Some sedation in dental practices is given by people with less skill or experience - they may call themselves anaesthetists but I wouldn't let them sedate me!!!
With this proviso it is no big deal. You will be sore for a day or so but if you were not a pilot you would be back at work on the second day
