Conscious sedation for gag reflex

[Jackc20]

Basically I’ve got a bad gag reflex so this has stopped me getting any dental work done in recent years, but I managed to book an appointment and they’ve offered me conscious sedation for it to help with my gag reflex. Does anyone know if this actually helps? I’ve read that it can suppress or eliminate the gag entirely for the work, which I hope it does but if anyone who’s been in a similar position to me can help me understand it a bit better or reassure me it works it would be greatly appreciated.
