Dental X-Rays For Your Child

Parents often question the need for dental X-rays (radiographs or films). Just as a broken bone or lung disease require a radiograph for a diagnosis, dental decay or other pathology (disease) of the oral cavity may require a radiograph for diagnosis. Tooth decay in children spreads rapidly in primary (baby) teeth.

Bitewing Radiograph(s)

These films, usually two, identify the presence of decay between the back (posterior) teeth. Decay between the teeth is called interproximal decay. By four and one-half years of age, the baby (primary) molars usually touch or contact each other. Interproximal decay can spread to the adjacent tooth if the teeth are in contact. If there are spaces between the primary molars, and there is no other evidence of decay, these films may not be necessary until later. A lack of spacing between the primary teeth predisposes a child to a much higher incidence of interproximal decay. Early detection permits your dentist to restore (repair) the tooth in less time and preserve tooth structure.

Periapical x-Ray

This film is used to examine the area around the tip of the root(s) or in between the roots. Primary teeth have long roots before they are resorbed (dissolved) by the pressure of the erupting permanent tooth. A root fracture after trauma, deep decay, infection, the need for root canal treatment, the presence of extra teeth, or absence of developing teeth are some of the findings with this film.

Occlusal Radiograph

This film evaluates the presence or absence of the upper and lower front teeth (incisors). It may also be used to diagnose fractures of teeth or bone and extra or missing teeth.

Panoramic x-Ray

Some pediatric dentists request this film around seven or eight years of age, when all eight permanent incisors have erupted. Although this not as accurate in diagnosing decay, it may provide an alternative if a child has a gag reflex that has prohibited taking a periapical or bitewing radiograph. The film is outside the mouth in a machine that revolves around the head. A view of the entire upper and lower jaw is obtained. This is commonly obtained by orthodontists prior to treatment. The panoramic radiograph may reveal or evaluate:

• Missing teeth
• Extra teeth
• Tumors, cysts, or other disease
• Improper position of teeth
• Broken bones after trauma
• Development of the permanent teeth
• Future crowding
• Wisdom teeth

Cephalometric Radiograph

This film ordinarily is obtained by an orthodontist in order to make a diagnosis of a child's bite (occlusion) and to determine the best treatment plan. It measures the relationship of the bones of the head and jaws.

Now, you are "in the know" for your child's next dental X-rays!

Kid's Dentist: Time For Teething

If babies could talk, they might have a few things to say about their troubles with teething: "Ooohh, do my gums ever hurt!" Since they can't, parents and caregivers must stay alert to signs of teething: drooling, fussiness, redness of gums and cheeks, sleeplessness, and maybe a loss of appetite. The first signs of teething may begin as early as three to four months of age. Baby teeth usually begin appearing between the ages of 6 to 16 months.

What Can Help My Child Feel More Comfortable While Teething?

Pay attention to the signs of teething and offer a big dose of TLC (tender loving care) and some relief of discomfort with some tried and true teething tips:

• Gently massage the baby's gums with a clean, cool, damp gauze pad or with your clean finger.
• Give your baby a cool non-plastic spoon to place into his or her mouth. Do not freeze the spoon.
• Allow your baby to chew on a cooled teething ring or moistened washcloth. Note: For safety reasons, do not leave your baby unattended while chewing on these things. Avoid plastic teething rings because a piece may break off and the baby's mouth could be cut or choking could occur. Also, teething rings should not be placed in the freezer. The frozen ring may stick to the lip, tongue, or gums and tear the tissue.
• If you apply over-the-counter topical medication, or if you use Acetaminophen (Tylenol or Tempra), follow the instructions on the label carefully and consult your doctor. Too much may cause liver damage. Over-the-counter medications should not be routinely given to an infant without a doctor's approval.

How Should I Care for My Baby's New Teeth?

As soon as your baby's teeth are visible, it's time to begin brushing! Baby teeth are susceptible to tooth decay that can lead to damage of permanent teeth. In the morning and before bedtime, brush teeth with a soft-bristled toothbrush and water only. Do not use toothpaste until your baby reaches two years of age to prevent accidental swallowing. After that, use just a dab (the size of a match-head) of fluoride toothpaste.

Be sure to schedule your child's first dental exam around the time of his or her first birthday (definitely no later than 16 months of age). Routine dental visits reveal any conditions that can be treated early as well as establish your child's dentist as a "healthy smile" partner.
