What kinds of sedatives are available?

Before administering any sedative, the dentist must analyze the full medical history of the patient, as well as taking note of any current medications.
Here is an overview of some of the most common types of dental sedatives:

Nitrous Oxide
Nitrous oxide, or “laughing gas,” is used as a mild sedative.  It is delivered through a nose hood, and is administered throughout the entire procedure.  Nitrous oxide elevates the general mood and can evoke a general sense of well-being.  Most importantly, it relieves anxiety and reduces pain during the procedure.  In addition, some tingling and numbness may be felt. There are few side effects associated with nitrous oxide, and it has been safely used in dentistry for many years.

Oral Conscious Sedation
Oral conscious sedation is an excellent choice for people who fear needles.  Oral medication is provided prior to treatment in order to induce a moderate state of sedation.  Though oral sedatives do not cause sleep, they usually dull the senses.  This means that most patients cannot remember the pain, smells or noises associated with the procedure.  Usually, a dose of medication is taken prior to the appointment, and then topped up during the procedure as required.
