Sedation Dentistry

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 patient’s 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.

IV Sedation

IV Sedation, also called general anesthesia, uses medications to allow the patient to go to sleep while receiving dental treatment. Patients with high levels of anxiety or with special needs may benefit from IV Sedation.  General anesthesia can also be a good option for patients with extensive tooth decay or for patients who are undergoing surgical dental procedures.  The doctor can discuss the risks and benefits of general anesthesia to help you decide if this is a good choice for your child.
