Dental cleaning while on these wonderful meds

Does anyone know if you can keep on your meds for a general cleaning?

Understand for a cleaning I am pre medicated with my very favorite drug - valium and then gassed. Despite the fact its the ONLY time I get it. I only go to the dentist every few years. Now the fact a dentist can walk in a room and turn me to quivering pile of flesh may be a problem but the drugs are not. Extractions and more extensive work, they need to be aware. They will either have you off the meds or pretreat with antibiotics. But as with all things ask.
