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!

Fresh Talk For Your Mouth

As a teen, you've got plenty to do -- going to school, homework, participating in after-school activities, spending time with friends, perhaps working a job, and other time commitments. Caring for your appearance also is a top priority, including your teeth. By doing so, you're rewarded with a bright, winning smile that really attracts attention!

Sometimes I Come Home So Tired After Long, Busy Days, I Don't Feel Like Brushing My Teeth. Does it Really Matter?

Yes, it does! If you haven't brushed your teeth since the morning, your mouth is filled with cavity-causing bacteria. When the sugar and starch from the day's food, snacks, or drinks combine with plaque (that sticky film on your teeth), an acid is produced. That acid attacks your tooth enamel. If this is repeated often, those acid attacks can break down enamel and cause cavities while you sleep. So, those few extra minutes it takes to brush your teeth really are important for cavity prevention.

What Can I Do to Make Sure My Breath Is Really Fresh?

Commercial products claim they will make your breath fresher, but the only way to make sure your breath is truly fresh is to practice good oral hygiene. In fact, too many breath mints and hard candies with sugar can lead to tooth decay. If you are constantly using breath mints, breath sprays, or mouth rinses in an effort to cover up bad breath, you may have a problem that needs correction.

If you neglect daily hygiene over time, bad breath can become a symptom of more serious dental problems. Teeth that are not cleaned properly become a place for bacteria to multiply in your mouth, causing cavities and gum disease. Gum disease produces bad breath and that's gross! So brush, floss, and brush or scrape your tongue.

If you smoke, bad breath comes with the habit. Smoking also puts you at an increased risk for developing gum disease. Brushing and flossing your teeth may slow the development of gum disease but smoking can lead to serious oral health problems, including oral cancer.

Can Dieting or Taking Medications Affect My Oral Health?

Hunger can contribute to bad breath. This is because of the chemical changes that occur as your body turns fat and protein into the energy it needs. Chemical changes caused by taking prescription or over-the-counter medications can also affect mouth odor.

Isn't a Mouth guard Just for Those Who Wear Braces?

No! Every year, more than 200,000 people are treated by dentists and oral surgeons for sports-related injuries, including broken and knocked-out teeth, concussions, jaw fractures, and neck and head trauma. Many of these could be avoided if athletes and sports enthusiasts used a mouth guard. Anyone participating in sports, especially contact sports, should wear protective mouth guards for safety.

Different types of mouth guards provide various advantages and degrees of protection -- from off-the-shelf to custom-fitted.

If you let good oral care habits slip away, you might be setting yourself up for some undesirable or painful events. Taking care of your teeth by brushing at least twice a day, cleaning between your teeth, avoiding smoking, and protecting yourself from injury by wearing a mouth guard does make a big difference. It matters to your mouth -- just a few minutes daily for clean teeth, fresh breath, and a magical smile!
