Dental X-rays: The Inside Story

July 15th, 2026

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. Parulkar 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 Lewis Center, OH 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!

How can I protect my child's teeth during sports?

July 8th, 2026

Sports are great for children for a variety of reasons. Children can develop their motor skills, learn how to solve conflicts and work together, and develop their work ethics. As a parent, you may recognize the benefits of sports, but also naturally worry about your child’s health and safety. Your job goes beyond providing a water bottle and making sure your child follows the rules of the game.

Although you may not think of your child’s teeth first when you think about sports, accidents can happen that affect your children’s teeth. A stray hockey stick, an errant basketball, or a misguided dive after a volleyball are examples of ways a child could lose a tooth. In fact, studies show that young athletes lose more than three million teeth each year.

Becoming a Better Athlete to Protect Teeth

Becoming a better athlete involves refining skills, learning the rules of the game, and being a good sport. These components are not just about winning. They are also about safety. Young athletes who are better ball-handlers and who are careful to avoid fouls and penalties are less likely to have harmful contact with the ball, teammates, or opponents. Children who are better roller-bladers are less likely to take a face plant into the blacktop, and more likely to save their teeth. Being a good sport and avoiding unnecessary contact is one way to protect teeth.

Proper Protective Equipment for Teeth

If your child is in a sport that poses a high threat to teeth, it is essential for your child to wear a mouthguard. Mouthguards fit your child’s mouth and consist of soft plastic. Dr. Parulkar can custom fit a mouthguard if generic ones are uncomfortable. While children may resist wearing a mouthguard initially, your persistence in insisting that they wear it should be enough to convince them. A helmet or face mask provides additional protection.

While prevention is best, rapid treatment can improve the situation if your child does happen to lose a tooth during sports. Rapid implantation can work in about ten percent of cases. To learn about ways to save a lost tooth, contact our Lewis Center, OH office.

Considerations When Picking the Right Mouthwash

July 1st, 2026

A solid oral health routine begins with daily brushing, flossing, and rinsing. Without a consistent oral health regimen, you may begin to experience tooth decay and bacterial infections. Few patients ask Dr. Parulkar about different mouthwash options, so we’ve put together a list of the conditions that mouthwashes can treat. This should help you decide which oral rinse would be best for you.

Gum Health

Antiseptic mouthwashes reduce large amounts of bacteria on and near the gum line and generally help to decrease your chances of developing gingivitis. The key ingredients of antiseptic mouthwashes are antibacterial and antimicrobial items. Antiseptic mouthwash is a preferable option if you are concerned about the general gum health of your mouth.

Fluoride

Fluoride is a great tool for preventive tooth decay treatment. It prevents tooth decay and is great for oral health in general because it kills germs that can live in your mouth. Fluoride also builds stronger teeth. If you’re a bottled water drinker, Dr. Parulkar may recommend that you purchase a simple fluoride rinse to use after brushing.

Bad Breath

Fluoride mouthwash can be used to fight any bad breath issues you may be facing. It’s designed to combat any bacteria that might be building up in your mouth. Most mouthwashes will help eliminate bad breath, but some are specifically designed to address this difficult problem. If you feel as though this might be turning into a chronic problem, please contact Dr. Parulkar to discuss other options that would be effective for treating your symptoms.

American Dental Association (ADA Approval)

The ADA reviews all mouth rinses for safety measures and to prove effectiveness. Any mouthwash approved by the ADA has met strict guidelines according to whether the manufacturer’s claims are supported with scientific evidence. If you’re looking for a quality mouthwash, look for one that has the ADA seal of approval to ensure you have a great rinse for your mouth.

Considerations

When you’re trying to decide which mouthwash to pick, contact our Lewis Center, OH or ask Dr. Parulkar during your next appointment. If you experience a burning sensation in the soft tissues of your mouth, be sure to discontinue use immediately. Avoid letting children under age six use a mouth rinse, and be sure to keep all mouthwashes out of the reach of children, because they contain alcohol and other substances that could be harmful.

What is baby bottle tooth decay?

June 24th, 2026

Great question! Baby bottle tooth decay is the development of cavities caused by the frequent and long-term exposure of a child's teeth to liquids containing sugars. These liquids include milk, formula, fruit juice, sodas and other sweetened drinks. The bacteria in the mouth thrive on this sugar and produce acids that attack the infant's teeth and gums. After numerous attacks, tooth decay can begin.

The first rule is to make sure your child does not fall asleep with a bottle containing milk, formula, juice or other sweetened liquids. Giving an infant a sugary drink before bedtime is harmful because the flow of saliva decreases during sleep, allowing the sugary liquids to linger on the child's teeth for an extended period of time. If left untreated, pain and infection can result.

So, how can you prevent baby bottle tooth decay? Be sure to clean and massage the baby's gums once a day to help establish healthy teeth and to aid in teething. When brushing your child's teeth, use a soft toothbrush, as well non-fluoride toothpaste. Once your little one is able to spit, around the age of two, you should begin using fluoride toothpaste. From the beginning, have your little one practice spitting the toothpaste out after brushing. That way, he or she will already have the good habit of spitting when you switch to fluoride toothpaste, which should never be swallowed.

Also, be aware that children should visit Delaware Pediatric Dentistry when they are between six and 12 months old. Please give us a call if your child hasn't visited our Lewis Center, OH office in the last six months!
