Sedation dentistry is used to provide a relaxing and anxiety-free experience for certain people receiving dental treatment. It enables individuals too afraid to go to the dentist to receive the dental care they need while avoiding the common apprehension known as dental phobia.

Sedation is a process used to establish a relaxed, easy and calm state through the use of sedatives. Sedative drugs (tranquillizers, depressants, anti-anxiety medications, nitrous oxide, etc.) can be administered in a variety of ways. In the past, intravenous (IV) sedation – sedatives delivered via injection into the blood vessels of the hand or arm – was predominantly used to sedate a dental patient.

IV sedation is both safe and effective when administered by a trained professional. Today, however, sedation dentistry has evolved to be even more conducive to a relaxing experience. Patients have alternatives to the traditional modalities of inhalation (nitrous oxide or “laughing gas”) and IVs, such as those offering a "no needle” (meaning, no injection) approach that many people find more appealing.
