Anxiety over a dental procedure can also be soothed through the use of nitrous oxide, a sweet-smelling gas made up of nitrogen and oxygen (also known as "laughing gas"). Nitrous oxide is given through a mask that fits snugly over your nose about five minutes before the dental procedure. It is a safe and well established method to deal with dental anxiety and discomfort.  It calms and has a comforting effect even though you stay awake and remain in control through a dental procedure that still allows you to communicate. It also tends to lessen anxiety, raise the pain threshold, reduces an overactive gag reflex and makes time pass more quickly.

Sedation dentistry is not necessary for everyone. However, if you have certain conditions or feelings that have prevented you from seeking dental care, sedation dentistry will allow you to get the treatment you need. People experiencing the following conditions are candidates for sedation dentistry:

• High fear and stress

• Past traumatic dental experiences

• Difficulty getting numb

• An overactive gag reflex

• Very sensitive teeth

• Complex dental problems

• Busy schedule does not allow dental care that would normally require multiple appointments

• Detest needles and shots

• Hate the noises, smells and taste associated with dental care

• Are afraid to show or embarrassed about your teeth
