Conscious Sedation

Conscious sedation is a medicine to help you relax (a sedative) and to block pain (an anesthetic) during a medical or dental procedure. You will probably stay awake, but may not be able to speak

It's a moderate level of sedation, so you're still technically awake but feeling very carefree. It's sometimes called conscious sedation dentistry or “twilight sleep” because it creates a state of short-term amnesia (forgetfulness) where you experience insensitivity to pain without the loss of consciousness.
