Sedation Dentistry for Children in Apex

Last updated
Sedation dentistry can help children and teens feel calmer and more comfortable during dental care. It may be considered for young patients with dental anxiety, a sensitive gag reflex, difficulty remaining still, previous negative experiences, sensory sensitivities, or concerns about completing treatment.
Dr. Michael Kim reviews each child’s health history, treatment needs, anxiety level, ability to breathe through the nose, and expected level of cooperation before determining whether nitrous oxide is appropriate. Nitrous oxide is not needed for every child, and its use is based on an individual evaluation.
Nitrous Oxide
Nitrous Oxide Sedation for Children in Apex: Nitrous oxide, commonly called laughing gas, is a mild sedative delivered through a small mask placed over the child’s nose. It can reduce anxiety while allowing the child to remain awake, responsive, and able to communicate throughout treatment.
The concentration can be adjusted during the procedure based on the child’s response. Once treatment is complete, the nitrous oxide is stopped and oxygen may be administered. The effects generally wear off within several minutes, but each child is evaluated before leaving the office.
Nitrous oxide works best when a child is willing to wear the nasal mask and can breathe comfortably through the nose. Local anesthesia may still be needed to numb the treatment area during fillings, extractions, or other procedures.

| Pediatric Nitrous Oxide Outcome | Percentage | What the Research Shows |
|---|---|---|
| Sessions without reported adverse effects | 97.5% | In a pediatric hospital study involving 688 nitrous oxide sessions, adverse effects were reported in 2.5% of sessions. This means 97.5% were completed without a reported adverse effect. |
| Successful sessions during the final study year | 94.1% | A study of 803 pediatric nitrous oxide sessions reported a 94.1% success rate during the final year evaluated. The researchers observed improved success as the dental team gained experience using the technique. |
| Successful pediatric nitrous oxide sessions | 92.7% | Research involving 480 children ages three to 17 reported successful dental treatment in 92.7% of 803 nitrous oxide sessions. |
| Successful sessions among children without a reported disability | 87.4% | In a pediatric hospital study, 549 of 628 sessions involving children without a reported intellectual disability were completed successfully. |
| Successful sessions in a large pediatric hospital study | 86.3% | A study involving children ages four to 17 reported successful completion of treatment in 86.3% of 688 nitrous oxide sessions. |
| Successful sessions among children with intellectual disabilities | 75% | In the same hospital study, 45 of 60 sessions involving children with intellectual disabilities were completed successfully. Individual needs and responses varied considerably. |

Reported outcomes come from specific pediatric populations, clinical settings, and sedation protocols. Individual experiences vary according to age, anxiety, medical history, sensory needs, treatment complexity, nasal breathing, willingness to wear the mask, and response to sedation.
Key Findings
Children Remain Awake
Nitrous oxide promotes relaxation without typically causing unconsciousness. Children remain able to respond and communicate during treatment.
The Level Can Be Adjusted
The concentration can be increased or decreased throughout the appointment according to the child’s response and treatment needs.
The Effects Wear Off Quickly
Nitrous oxide has a rapid onset and recovery compared with deeper forms of sedation.
It Does Not Replace Numbing
Nitrous oxide helps manage anxiety and awareness, while local anesthesia may still be needed to numb the treatment area.
Wearing the Mask Is Important
A child must generally accept the nasal mask and breathe through the nose for nitrous oxide to work effectively.
Candidacy Requires Evaluation
Medical history, current medications, respiratory health, nasal congestion, vitamin B12-related concerns, and other individual factors are reviewed before treatment.
Help Your Child Feel More at Ease
Schedule a consultation at Green Level Pediatric Dentistry & Orthodontics in Apex. Dr. Michael Kim will review your child’s health history, anxiety level, ability to cooperate, and planned procedure to determine whether nitrous oxide may support a calmer and more comfortable appointment.
Questions Apex Families Ask About Sedation Dentistry
What is nitrous oxide?
Nitrous oxide is a mild inhaled sedative used to help children feel calmer during dental treatment. It is delivered with oxygen through a small mask placed over the nose. The child remains awake and able to respond throughout the appointment.
How quickly does nitrous oxide work?
The relaxing effects generally begin within a few minutes. Because the concentration can be adjusted during treatment, Dr. Kim can tailor the level of relaxation according to the child’s response.
Will nitrous oxide prevent pain?
Nitrous oxide primarily reduces anxiety and helps the child relax. It does not replace local anesthesia when a procedure requires the treatment area to be numbed.
Is nitrous oxide safe for children?
Nitrous oxide has a long history of use in pediatric dentistry and is considered safe for appropriately selected children when administered according to established guidelines. The child is observed throughout treatment, and the concentration can be adjusted as needed.
Can my child return to normal activities afterward?
The effects usually wear off within several minutes after the nitrous oxide is stopped and oxygen is provided. Many children can return to normal activities after the dental team confirms that they have recovered appropriately. Parents should follow any instructions provided for their child’s specific appointment.
Who may not be a candidate for nitrous oxide?
Nitrous oxide may not be appropriate for a child who cannot tolerate the nasal mask, cannot breathe comfortably through the nose, or has certain respiratory, medical, behavioral, or vitamin B12-related concerns. Dr. Kim reviews the child’s health history and individual needs before recommending sedation.
