Dental X-rays: The Inside Story

August 3rd, 2022

Pediatric dentists strive to make your children’s visits welcoming and worry-free, and, we want the same for you! Ask us about any questions you might have. We are happy to explain procedures, equipment, and sedation options so you know just how safe and comfortable your child’s experience can be. And if X-rays are a concern, we can put your mind at ease here as well.

What Exactly Are X-rays?

Sometimes parents feel reluctant about the process of imaging because X-rays are a kind of radiation. But the fact is, radiation is all around us. We are exposed to radiation naturally from our soil and water, sun and air, as well as from modern inventions such as cell phones, Wi-Fi, and air travel.

Why is radiation so common? Because matter throughout the universe constantly gives off energy, and the energy that is emitted is termed radiation. This radiation takes two forms—as particles (which we don’t need to consider!) and as traveling rays. This second type is known as electromagnetic radiation, created by photons traveling in regular waves at the speed of light.

We are exposed to electromagnetic radiation every day, because, whether we can see them or not, these different wavelengths and frequencies create various forms of light. Radio waves, microwaves, infrared, visible, and ultraviolet light, X-rays, and gamma rays are all part of the electromagnetic light spectrum.

Different types of radiation on this spectrum have different wavelengths and different frequencies, and produce different amounts of energy. Longer wavelengths mean lower frequencies and less energy. Because X-rays have shorter wavelengths and higher frequencies than, for example, radio waves and visible light, they have more energy.

How Do Dental X-rays Work?

An X-ray machine produces a very narrow beam of X-ray photons. This beam passes through the body and captures images of our teeth and jaws on special film or digital sensors inside the mouth (intraoral X-rays), or on film or sensors located outside the mouth (extraoral X-rays). These X-ray images are also known as radiographs.

Why are X-rays able to take pictures inside our bodies? Remember that higher energy we talked about earlier? This energy enables X-rays to pass through the softer, less dense parts of our bodies, which are seen as gray background in a radiograph. But some substances in our bodies absorb X-rays, such as the calcium found in our bones and teeth. This is why they show up as sharp white images in radiographs. 

There are different types of common dental X-rays which are used for pediatric exams, including:

  • Bitewing X-rays, which are used to check on the health of the back teeth.
  • Periapical X-rays, which allow us to look at one or two specific teeth from crown to root.
  • Panoramic X-rays, which use a special machine to rotate around the head to create a complete two-dimensional picture of teeth and jaws.

Why Do We Need X-rays?

If all of our dental conditions were visible on the surface, there would be no need for X-rays. But there are many conditions that can only be discovered with the use of imaging—infection, decay, or injuries, for example, can show up as darker areas in the teeth or jaws. Among their many diagnostic uses, X-rays can help us find:

  • Cavities between teeth
  • Damage to the tooth’s pulp which might require root canal treatment
  • Injuries to teeth or roots after trauma
  • Abscesses, tumors, or other conditions that might be causing swelling or pain
  • Unusual position or development of the teeth before and as they erupt
  • Alignment and development of wisdom teeth

X-rays can also serve an important preventative role, by discovering small problems before they become major ones.

How Do Dentists Make Sure Your Child’s X-rays Are as Safe as They Can Be?

First of all, the amount of radiation patients are exposed to with a dental X-ray is very small. In fact, a set of bitewing X-rays exposes us to slightly less than the amount of radiation we are exposed to through our natural surroundings in just one day. Even so, Dr. Jason Rector and our team are committed to making sure young patients are exposed to as little radiation as possible.

Radiologists, the physicians who specialize in imaging procedures and diagnoses, recommend that all dentists and doctors follow the safety principal known as ALARA: “As Low As Reasonably Achievable.” This means using the lowest X-ray exposure necessary to achieve precise diagnostic results for all dental and medical patients.

The guidelines recommended for X-rays and other imaging have been designed to make sure all patients have the safest experience possible whenever they visit the dentist or the doctor. We ensure that imaging is safe and effective in a number of ways:

  • We take X-rays only when they are necessary.
  • We provide protective gear, such as apron shields and thyroid collars, whenever needed.
  • We make use of modern X-ray equipment, for both traditional X-rays and digital X-rays, which exposes patients to a lower amount of radiation than ever before.
  • We set exposure times based on each child’s size and age.

X-rays play an important part in helping us make sure your child’s teeth stay their healthiest. If you have any concerns, contact our Ocean Springs office. When it comes to making sure you’re comfortable with all of our procedures, including any X-rays that might be necessary, we’re happy to give you all the inside information!

Are baby teeth really that important?

July 27th, 2022

Your infant’s first teeth will begin to appear around six to 12 months of age. You might wonder how important these primary teeth really are. After all, baby teeth are destined to fall out within a few years and be replaced by a full set of permanent teeth. However, baby teeth have important functions, and proper care can set the stage for excellent oral and overall health.

Promote Better Nutrition

The appearance of your baby’s primary teeth around six to 12 months of age coincides with changes in your infant’s nutritional needs. Beginning at six months, exclusive breastfeeding is no longer nutritionally sufficient; this is the age at which you should introduce solid foods.

At six to eight months, when your baby can start to chew, strained or pureed fruits and vegetables are appropriate. As your little one’s teeth grow in and chewing abilities progress through 12 months of age, you can gradually add cereal, bread, cooked meats, and other adult foods to his or her nutritious diet.

Increase the Life Expectancy of Baby Teeth

Although baby teeth are inevitably going to fall out and be replaced by permanent ones, making baby teeth last serves an important role that can have benefits into the future. Baby teeth serve as placeholders for permanent teeth. If they decay and fall out too soon, permanent teeth are more likely to grow in crooked.

How to Take Care of Baby Teeth

Your baby’s primary teeth are already in his or her mouth at birth; they are just invisible because they have not broken through the gums. Since they are already present, your baby can get cavities if you do not practice proper oral hygiene from the beginning.

  • Do not let your baby fall asleep with a bottle in his or her mouth.
  • Brush your child’s baby teeth twice a day as soon as they come in.
  • Floss your child’s teeth as soon as he or she has two teeth that touch.
  • Visit Rector Pediatric Dental for your baby’s first checkup when the first tooth arrives.

They're just baby teeth, right?

July 20th, 2022

“But they are only baby teeth; won’t they just fall out?” Our team at Rector Pediatric Dental has had these questions asked many times from parents over the years. Primary teeth, or “baby teeth,” will indeed come out eventually, to be replaced by permanent teeth as the child grows and develops. These teeth serve a great purpose as the child continues to develop and require specific care.

Because baby teeth are temporary, some parents are unenthusiastic about fixing cavities in them. This may be due to the cost or having to force a child undergo the process—especially having to receive an injection. But if a cavity is diagnosed early enough, an injection can often be avoided. More important, failure to fill cavities in primary teeth when they are small and manageable can have lasting consequences in cost and health concerns. Serious illnesses in children have been diagnosed which began as a cavity.

Primary teeth act as a guide for permanent teeth. When decay reaches the nerve and blood supply of a tooth, this can cause an abscess. Severe pain and swelling may result. At that point, the only treatment options are either to remove the tooth or to perform a procedure similar to a baby root canal. When a primary tooth is lost prematurely—to decay or a painful abscess—the adjacent teeth will often shift and block the eruption of a permanent tooth. Braces or spacers become necessary to avoid crowding or impaction of the permanent tooth.

There is nothing more heartbreaking for Dr. Jason Rector than to have to treat a child experiencing pain and fear. To all the parents of my little patients our team strongly recommend filling a small cavity and not waiting until it becomes a larger problem such as those described above.

Prevention is the key to a healthy mouth for our smallest patients. Parents should allow the child to brush his or her teeth using a pea-sized amount of fluoride toothpaste and then take a turn to ensure the plaque gets removed from all surfaces: cheek side, tongue side, and chewing edges of all the teeth.

Why Baby Teeth Matter

July 13th, 2022

Sleepless nights, crankiness, drooling—how can such tiny teeth cause such a big fuss? But all those uncomfortable days and nights are forgotten when your baby’s first teeth make their appearance. Why? Well, certainly because your child is happier, but also because you know baby teeth, or primary teeth, are important for your child’s growth in so many different ways.

  • Chewing and Eating

Your baby might enjoy solid foods at an early age, but real chewing doesn’t happen until all the baby molars appear between the ages of one to three years. This is the time to feed children size-appropriate and texture-appropriate foods so they acquire proper chewing and eating habits for healthy digestion. Chewing also helps develop your child’s jaw and facial muscles.

  • Developing Speech

Pronouncing many of the common sounds used in speech often requires tongue and teeth working together. If teeth are missing or there is a bite problem such as an open bite, it might be more difficult to pronounce words properly. This could be only a temporary delay, or it could require speech therapy when your child is older.

  • Setting the Stage for Permanent Teeth

Baby teeth not only help with speech and jaw development, but they serve as space holders for permanent teeth. If a primary tooth is lost too early, a permanent tooth might “drift” into the empty space. The adult tooth will not have the room to fit where it should, and crowding or misalignment can occur. This might cause orthodontic problems in the future.

  • Learning Healthy Dental Habits

You are your baby’s first dental health care provider! Wiping the gums and erupting teeth with a soft damp cloth after meals, gently brushing baby teeth when your toddler is young, teaching how to brush as your child gets older, helping to establish daily routines for brushing—all these practices will prepare your child for lifelong healthy dental habits.

  • Making the Dentist a Regular Part of Your Child’s Life

Your child should visit our Ocean Springs office soon after that first tooth comes in, and definitely by the age of 12 months. Dr. Jason Rector can help with suggestions for your brushing and flossing routine, make sure your child’s teeth are healthy and clean, and ensure that teething progress is on track. In later visits, we will examine your child’s primary teeth and gums, and treat any problems, such as cavities, before they can become serious.

It turns out that baby teeth really are a big deal. Talk to us about suggestions for caring for your toddler’s teeth and about any questions you may have about teething progress, jaw and facial structure, speech development, or any other concerns at any time. We want to have a happy relationship with your child from the very start for a lifetime of healthy and confident smiles.
