Sedation dentistry refers to the use of sedation during dental treatment. Sedation is most commonly used during extensive procedures, for patients with dental phobia or for patients who find it difficult to sit still. There are different types of sedation, including nitrous oxide ("laughing gas"), oral sedatives and general anesthetic.

Sedation can range from the use of nitrous oxide to calm a patient to general anesthetics used to put patients to sleep. Patients with dental phobia, low pain tolerance, major dental treatment, physical handicaps or strong gag reflexes may require sedation. Procedures like fillings, crowns, bridges, root canals, extractions, cosmetic procedures and periodontal treatments often require sedation.

Sedation is endorsed by the American Dental Association and is an effective way to make many patients comfortable during their dental visit. Before using a sedative or anesthetic, it is important to tell your dentist about any medications or medical treatments you are receiving. Before administering any sedative or anesthetic, your dentist will talk to you about the process of sedation and pre- and post-sedation instructions.

Laughing Gas
Nitrous oxide, more commonly known as laughing gas, is often used as a conscious sedative during a dental visit. The gas is administered with a mixture of oxygen and has a calming effect that helps phobic or anxious patients relax during their dental treatment. Because it is a mild sedative, patients are still conscious and can talk to their dentist during their visit. After treatment, the nitrous is turned off and oxygen is administered for five to 10 minutes to help flush any remaining gas. The effects wear off almost immediately. Nitrous oxide rarely has side effects, although some patients may experience minor nausea and constipation. Your doctor will provide you with pre- and post-sedation instructions.

Oral Conscious Sedation
Some patients who require dental care but are fearful and anxious may require oral conscious sedation.  Oral conscious sedation is a light form of sedation given to the child in the form of a drinkable liquid in an amount measured for their weight.  The goals of sedation in the pediatric dental patient are to:

1. Facilitate quality care
2. Minimize the extreme of disruptive behavior
3. Promote a positive psychological response to treatment
4. Promote patient safety

Instructions for Children prior to Oral Conscious Sedation

1. No milk, breast milk, formula, or solid foods for 8 hours prior to sedation
2. Clear liquids up to 3 hours before the sedation
3. Be sure to let Doctor and office staff know if your child has been sick recently or has an existing cough or cold

Instructions following Sedation

1. Limit child’s activity for remainder of the day
2. Soft/Bland diet for the remainder of the day
3. Have adult monitor for the day
