At the end of the procedure, pure oxygen is given to the patient to clear out any remaining nitrous oxide.
Intravenous sedation is delivered through a needle inserted into the patient's vein.
Dressing the child in loose-fitting clothing also helps because it allows dental assistants to attach monitors quickly and without fuss.
Parents must provide a full medical history and tell the dentist if the child is receiving any prescriptions, over-the-counter medication or herbal supplements.
Before Sedation The American Academy of Pediatric Dentistry advises parents that children tolerate sedation and other dental procedures best if the parents understand what is happening and help prepare the child.
Parents must restrict food and drink before sedation, and it's especially important that parents follow these guidelines closely for key safety reasons, as sedation poses the risk of stomach contents being vomited and inhaled into the lungs.
Types of Sedation Oral sedation, nitrous oxide and intravenous sedation are the major types of sedation dentists provide.
The American Society of Dentist Anesthesiologists explains that nitrous oxide is used to send the child to sleep before a needle is inserted, usually into a vein on the back of the child's hand.
A tube is also inserted into the patient's throat to aid breathing.
The child may be confused or fussy and may feel nauseous.
Two adults should accompany the child or teen on the way home — one to drive and one to check the child's breathing.Nitrous oxide, or laughing gas, also helps children remain calm.
