How you feel while sedated will depend on the type of sedation you’re receiving. For example, nitrous oxide is known to make you feel relaxed, light, and euphoric. You may experience a slight tingling sensation in your limbs and get giggly, which is why this type of sedation is also referred to as “laughing gas”. Oral conscious sedation is designed to give you an even deeper sense of relaxation. You might have difficulty talking and even fall asleep during your procedure. As a result, time may appear to pass by more quickly during your appointment.
