Nitrous oxide, commonly known as "laughing gas," provides quick relaxation and wears off soon after treatment, while conscious oral sedation keeps patients awake but significantly reduces anxiety.
Conscious Oral Sedation
Conscious oral sedation is an alternative minimal sedation that allows you to remain awake but relaxed. For people who have a fear of dental procedures, conscious sedation may take away some of the anxiety. The doctor will combine the use of oral sedation along with a local anesthetic so you have little to no discomfort. You should plan to have someone bring you to the appointment and be available to drive you home following treatment.
Nitrous Oxide
Nitrous oxide, sometimes referred to as “laughing gas,” is an effective and safe sedation agent that is inhaled through a mask that fits over your nose to help you relax. Mixed with oxygen, nitrous oxide allows you to breathe normally through your nose, and within minutes you should start to feel the effects. You may feel light-headed or a tingling in your arms and legs. Some patients comment that their legs and arms feel heavy. Ultimately, you should feel comfortable and calm. The effects of nitrous oxide wear off quickly after the small mask is removed. Talk to the doctor about whether nitrous oxide would be a good option for you.
