If your child has an upcoming procedure, you might be wondering how pediatric dentists use different forms of sedation to ease your child’s anxiety and allow for the best experience.You might also be wondering about the safety level of sedation.
Not to worry, we will give you the info you need to put you more at ease!
Pediatric dentists generally use nitrous oxide (aka “laughing gas”) or general anesthesia for sedation, depending on the procedure. It also depends on the child’s level of anxiety.
Nitrous oxide is a mild sedative that puts your child in a state called “conscious sedation”, which is exactly what it sounds like: your child will be mildly sedated, but still able to speak, cough and breathe. It is not a general anesthesia and is only to alleviate anxiety.
This is by far the most common method of sedation, and is inhaled through a facemask. If you’ve never experienced nitrous oxide for yourself, it can be described as making you feel happy and relaxed. Your child might also feel a little light, or tingly. Even though it’s sometimes called laughing gas, it usually won’t make your child laugh uncontrollably. That would make our jobs pretty difficult!
General anesthesia (GA) on the other hand, puts your child in a much deeper state of sedation. This is usually a gas that is inhaled through a mask, administered by a specialized anesthesiologist and required for more intensive procedures – like surgeries.
Under general anesthesia, your child will be in a deeper form of sedation. They will feel no pain, and remain in that state until treatment is completed. If suggested for your child’s treatment, we will also consult with an anesthesiologist that will answer all questions prior to any treatment.
Nitrous oxide was first discovered in 1793, and has been used by medical professionals for over 150 years. In addition, each year in the US more than a million children under the age of 4 get general anesthesia for surgical procedures. Sedation (like nitrous oxide) is also used by thousands of dentists every day.
Luckily, pediatric dentists and staff are trained extensively on how to use sedation with kids, and it is extremely safe for children!
As a bonus, sedation is a win-win: it’s an effective way to keep children still for dental procedures, and also eases any anxiety they might feel! After a procedure that requires nitrous oxide, we let your child breathe 100% pure oxygen to flush out any residual nitrous oxide from their system.
While it only takes about 5 minutes for nitrous oxide to wear off, general anesthesia can stay in your child’s system for up to 24 hours. Until then, your child can experience confusion, drowsiness, be less coordinated or get off-balance sometimes. That’s why we always require a parent to be with the child until the anesthesia wears off. It’s also important to restrict any activities that require hand-eye coordination. Even after general anesthesia, most kids return to their normal activities that afternoon. They are encouraged to return to school and daycare the following days.
