X-ray imaging is a routine part of a child's dental care — and it undeniably makes a difference in preventing and treating dental disease. It's so routine, we can easily forget they're being exposed to an invisible form of electromagnetic radiation.Â And just like other sources of radiation, too much x-ray exposure could increase the risk of cancer.
But while it's possible for your child to be over-exposed to x-rays, it's highly unlikely. That's because healthcare professionals like dentists adhere to a standard known as ALARA when considering and administering x-rays. ALARA is an acronym for “as low as reasonably achievable.” In other words, we only want to expose a patient to the lowest and safest levels of x-ray dosage and frequency that will achieve the most benefit.
To achieve that standard, professional dental organizations advocate the use of x-rays only after a clinical examination of the patient, as well as a thorough review of their medical history for any usage of x-rays for other conditions. If x-rays are warranted, we then take further precautions to protect the patient and staff, and only use the type of x-ray application that's absolutely necessary. For most children that will be a set of two or four bitewing radiographs, which are quite effective for detecting decay in back teeth.
This dosage of radiation in a session of bitewing radiographs is roughly a fifth of the background radiation in the environment a child may be exposed to every day. By spacing these sessions at least six months apart, we're able to achieve a high level of decay detection at a safe and reasonable amount of x-ray exposure.
On top of that, the digital advances in x-ray imaging have reduced the amount of radiation energy needed to achieve the same results as we once did with film. These lower exposure levels and the ALARA standard helps ensure your child's exposure to x-rays will be well within safe limits.

The best way to prevent dental visit anxiety in your children is start those visits around their first birthday, and continue with them through childhood. Age One visits are the best way to ensure they're comfortable with the dentist now and that they'll continue the habit into adulthood.
But in spite of your best efforts and those of your dental provider, there's no guarantee your child won't experience dental visit anxiety at some point. If that happens, we recommend conscious sedation.
Conscious sedation is the use of certain medications to help a patient relax. It's not the same as anesthesia, which eliminates pain by numbing tissues (local anesthesia) or inducing unconsciousness (general anesthesia). During conscious sedation a patient remains awake or at the most in a dream-like state, can still respond to touch or verbal commands, and although monitored doesn't require assistance in heart or lung function.
We can induce this relaxed state in a number of ways: orally, with medication given by mouth a short time before the visit; intravenously, the medication delivered through a drip directly into the bloodstream; or by inhalation, usually nitrous oxide gas mixed with oxygen and delivered by mask.
Oral sedation is the most common. On the day of the procedure, we'll give your child one or more sedative drugs, usually in syrup form. For best results we advise they eat a low-fat dinner the night before and not eat or drink any food or liquid afterward. We typically use Midazolam and Hydroxyzine, both of which are proven safe and fast acting.
During the procedure, we'll also assign a team member to monitor their vital signs while they're under the influence of the drugs. We may also employ special positioning or immobilization equipment to keep movement to a minimum.
After the procedure, we'll continue to monitor vitals until they return to pre-sedation levels. The child should remain home the rest of the day to rest and return to school the next day.
Conscious sedation is regulated by states: providers must be trained and licensed to administer sedation drugs with continuing education requirements. Even so, the use of sedation for children is becoming more widespread and helps to safely ensure they're getting the dental care they need.

Although tooth decay is a major problem to watch for in your child’s teeth, it isn’t the only one. As their teeth transition from primary (“baby”) to permanent, you should also be on the lookout for a developing poor bite or malocclusion.
Although the signs can be subtle, you may be able to detect an emerging malocclusion, starting usually around age 6, if you know what to look for. Here are 4 signs your child may be developing a poor bite.
Excessive spacing. This is something that might be noticeable while the child still has their primary teeth. If you notice an excessive amount of space around the front teeth, the sizes of the jaws and the teeth may be disproportional.
Abnormal overlapping. The upper teeth normally just cover the bottom teeth when the jaws are closed. But a malocclusion may be forming if the lower teeth cover the upper (underbite), the upper teeth extend too far over the lower (deep bite) or there’s space between the upper and lower front teeth (open bite).
Different overlapping patterns. Watch as well for some of the teeth overlapping normally while others don’t, a sign of a cross bite. For example, the back upper teeth may cover their counterparts in a normal fashion while the lower front teeth abnormally overlap the top front. The roles here between front and back teeth can also be reversed.
Abnormal eruptions. Permanent teeth normally follow a pattern when erupting, but certain factors could disrupt the process. For example, a jaw that’s developed too small can cause crowding as incoming teeth vie for space; as a result, some permanent teeth may erupt out of their proper position. Likewise, if a baby tooth is out of its normal position or prematurely lost, the permanent tooth may erupt out of position too.
The good news with each of these developing bite problems is that we can correct them or at least minimize their future effect if caught early. So if you notice any of these signs or anything else out of the ordinary, see an orthodontist as soon as possible. It’s also a good idea to have your child undergo a thorough orthodontic evaluation around age 6.
