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.  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.

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.

Sometimes it seems that appearances count for everything—especially in Hollywood. But just recently, Lonnie Chaviz, the 10-year-old actor who plays young Randall on the hit TV show This Is Us, delivered a powerful message about accepting differences in body image. And the whole issue was triggered by negative social media comments about his smile.

Lonnie has a noticeable diastema—that is, a gap between his two front teeth; this condition is commonly seen in children, but is less common in adults. There are plenty of celebrities who aren’t bothered by the excess space between their front teeth, such as Michael Strahan, Lauren Hutton and Vanessa Paradis. However, there are also many people who choose to close the gap for cosmetic or functional reasons.

Unfortunately, Lonnie had been on the receiving end of unkind comments about the appearance of his smile. But instead of getting angry, the young actor posted a thoughtful reply via Instagram video, in which he said: “I could get my gap fixed. Braces can fix this, but like, can you fix your heart, though?”

Lonnie is raising an important point: Making fun of how someone looks shows a terrible lack of compassion. Besides, each person’s smile is uniquely their own, and getting it “fixed” is a matter of personal choice. It’s true that in most circumstances, if the gap between the front teeth doesn’t shrink as you age and you decide you want to close it, orthodontic appliances like braces can do the job. Sometimes, a too-big gap can make it more difficult to eat and to pronounce some words. In other situations, it’s simply a question of aesthetics—some like it; others would prefer to live without it.

There’s a flip side to this issue as well. When teeth need to be replaced, many people opt to have their smile restored just the way it was, rather than in some “ideal” manner. That could mean that their dentures are specially fabricated with a space between the front teeth, or the crowns of their dental implants are spaced farther apart than they normally would be. For these folks, the “imperfection” is so much a part of their unique identity that changing it just seems wrong.

So if you’re satisfied with the way your smile looks, all you need to do is keep up with daily brushing and flossing, and come in for regular checkups and cleanings to keep it healthy and bright. If you’re unsatisfied, ask us how we could help make it better. And if you need tooth replacement, be sure to talk to us about all of your options—teeth that are regular and “Hollywood white;” teeth that are natural-looking, with minor variations in color and spacing; and teeth that look just like the smile you’ve always had.

Because when it comes to your smile, we couldn’t agree more with what Lonnie Chaviz said at the end of his video: “Be who you want to be. Do what you want to do. Do you. Be you. Believe in yourself.”

If you’re about to undergo orthodontic treatment, you’re going to face a challenge keeping your teeth and gums clean wearing braces. That in turn could increase your chances for tooth decay or periodontal (gum) disease, which could diminish your future dental health and disrupt your current orthodontic treatment.

The main hygiene tasks of brushing and flossing are more difficult with braces because of the fixed hardware on the teeth. Your toothbrush or floss can’t always easily maneuver around the wires and brackets, increasing the chances you’ll miss some areas. These neglected areas can then accumulate dental plaque, a thin film of bacteria and food particles that’s most responsible for disease.

But although difficult, effective oral hygiene isn’t impossible.  First and foremost, you’ll need to take more time to be thorough with brushing and flossing than you might normally without braces.

Second, there are some specialized hygiene tools to make the job easier. Instead of a regular toothbrush try an interproximal brush. This special brush has a long and thin bristled head (resembling a pipe cleaner) that can maneuver in and around orthodontic hardware much easier than a regular brush.

For flossing, use a floss threader, a device through which you thread floss on one end and then pass the other sharper end between your teeth. Once through, you release the floss from it and floss as usual, repeating the process with the threader for each tooth. Another option is an oral irrigator, a device that emits a pressurized spray of water between teeth to loosen plaque and flush it away. Many orthodontic patients have found this latter option to be quite effective.

Finally, continue seeing your regular dentist for regular appointments in addition to your orthodontist. Besides cleaning those hard to reach areas, your dentist can also provide other preventive measures like topical fluoride for strengthening enamel and prescription mouth rinses that inhibit bacterial growth. You should also see your dentist immediately if you notice signs of disease like spots on the teeth or swollen or bleeding gums.

Keeping your teeth clean while wearing braces is a top priority. Doing so will help ensure your new smile after braces is both an attractive and healthy one.

If you’re brushing and flossing daily, as well as seeing your dentist at least every six months, you’re doing the top things needed to maintain your dental health. But all your hygiene efforts could be undermined if you’re not eating a dental-friendly diet. Simply put, there are foods that protect and promote dental health and those that increase your risk of dental disease.

Diets in the latter category are typically high in added sugar and low in natural food fiber. The largest sources of these are processed sugars from sugar cane or beets and high fructose corn syrup. With just a little knowledgeable label reading, you can find sugar and its various aliases added to thousands of processed food items including pastries, candies, sodas and energy drinks.

Heavy consumption of processed sugars also contributes to dental disease. Disease-causing bacteria thrive on sugar as a food source, which fuels both their growth and their production of oral acid. Elevated acid levels can dissolve the minerals in tooth enamel faster than saliva can keep up. Softened enamel opens the door to tooth decay, while increased bacterial growth can lead to periodontal (gum) disease.

A diet, however, low in added sugar and high in fiber can have the opposite effect. Although fresh fruits and vegetables contain natural sugars, they also have indigestible parts called fiber that slow the digestion of any sugars and allow the body to more efficiently process them.  With the higher quantity of vitamins and minerals found in unprocessed foods, the overall effect of this diet is a decrease in your risk for dental disease.

Speaking of dental-friendly foods, we should also give honorable mentions to certain dairy items like cheese and milk that stimulate saliva production and are rich in calcium needed for tooth strength. Another beneficial category is both black and green tea, which contain antioxidants to fight disease and fluoride to strengthen enamel.

Adopting a low-sugar/high-fiber diet can have a profound impact on your overall health. Over time, you’ll also reap dental health rewards with stronger teeth and gums and a lower risk of tooth decay and gum disease.
