Healthy teeth make you happy to share your smile with the world. But there’s more to your smile than its beauty! There’s a lot of hard work going on, too.

Teeth Are Designed for Healthy Eating

Humans are omnivores, which means we can eat both meat and plants. That’s why our teeth have different shapes—they’re designed to help us eat different kinds of food. 

• Incisors, our front teeth, have sharper edges to help cut through meats and other harder foods when we bite.
• Canines, the pointed teeth, help tear food into bite-size bits.
• Premolars are flat topped and have two cusps, or raised points, which help grind food. 
• Molars are the flat-topped teeth in the back of the mouth. They have four cusps to grind and crush food into a paste. 

So: Incisors and canines bite and tear food into smaller pieces, and then molars and premolars crush and grind those pieces into a paste. Bite, tear, crush, grind—that’s a lot of work! But it’s the key to healthy digestion. 

Chewing is the first step in digestion. Digestion means breaking down our food into parts which our bodies can use as fuel to grow. When you chew your food well, it’s easier for your body to break that food down, to swallow it, and to get the proteins, vitamins, and minerals in your healthy diet. 

But when your teeth hurt, it’s hard to chew food well, which makes digestion harder and sometimes uncomfortable. To get the most from your healthy diet, you need healthy teeth!

Teeth Have Other Important Jobs, Too

• They Help Us Speak

Our teeth work with our tongues and lips to form many of the sounds which make up speech. Try saying the word “teeth,” and see how your tongue and teeth work together!

• They Help Shape Our Faces

Our teeth look great in smiles. But there’s more! Your teeth and the way they fit together in your jaw help shape the look of your chin, lips, cheeks, and the front and sides of your face. 

• They Help Make a Healthy Bite

Our teeth and jaws are designed to work together. When something’s not lined up just right, that’s called a malocclusion, or bad bite, and can cause problems with eating, speaking, and self-confidence. Your dentist might recommend orthodontic treatment to help your teeth and jaws look their best and work their best. 

Teeth Can Only Work Their Best with Your Help

You’re in charge! 

• Brush twice and floss at least once every day to clean away plaque and food particles from your teeth. This helps to protect them from cavities. 
• Eat a healthy diet to give you the vitamins and minerals which keep your teeth strong.
• Make sure you wear mouth protection when you play sports or do activities where you may fall, or collide with another person, or be hit with equipment like balls, bats, and pucks.   
• See your dentist regularly for exams and cleanings.

Talk to your pediatric dentist to learn more about how to help your teeth work their best for you—and be ready to share that beautiful smile!

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. Venetia Laganis 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 Maple Grove 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!

Many parents are unaware that children can also suffer from symptoms of halitosis, better known as chronic bad breath. This common oral problem affects a majority of the population, including both adults and children. During treatment for this condition, it’s worthwhile to focus on the cause of the problem. Take a look at the most common reasons why your child might develop bad breath.

Having constant bad breath can be embarrassing and troublesome. Most often, boys and girls develop halitosis as a side effect of some sort of upper respiratory infection. It may be a common cold, allergies, or flu symptoms.

When the nasal passages are blocked, it’s more likely that your child will breathe through the mouth. Mouth breathing may also occur if your youngster is put on medication that decreases saliva flow. Mouth breathing can make bad breath much worse if there isn’t enough saliva to cleanse the area.

Another cause of halitosis in children can be tonsillitis. When your child’s airway is constricted, he or she is more likely to mouth-breath. When the tissues in your mouth dry out, bacteria will grow and increase in potency. If you notice symptoms of tonsillitis in your child such as a fever, swollen throat, trouble swallowing, chills, or congestion, get your little one to treatment right away.

Halitosis in children is can also be caused by an infection of the mouth. If your child’s teeth or gums are infected, odor will developed if untreated. Infection can occur due to inadequate brushing and flossing, which can lead to gum disease or cavities. If cavities are left untreated, they can develop a strong, noticeable odor. If you think your child has an infection or cavity, contact Laganis Pediatric Dentistry and schedule an appointment.

Other causes of halitosis may be certain pungent foods your child eats, or bacteria built up on the tongue. Make sure your son or daughter brushes and flosses thoroughly every day. Some mouthwashes may be beneficial for your child to alleviate bad breath caused by leftover bacteria in the mouth. Other ways of treating of halitosis can vary, based on the cause of the problem.

If you’re unsure about why your child has halitosis, contact Laganis Pediatric Dentistry and we can help you figure out where the issue originated. Remember, masking symptoms of bad breath with gum or mints will be only a temporary fix. Your child’s bad breath problems can be helped with a little investigation from Dr. Venetia Laganis. Always feel free to call our Maple Grove office if you are concerned about your child’s oral health.

At Laganis Pediatric Dentistry, we are often asked “should I be concerned with my child’s thumb sucking?” So, our team thought we’d share what our thoughts are on your child sucking his or her thumb.

Infants Who Suck Their Thumbs

As infants begin experimenting with the basic functions of their mouths, from sucking on a bottle to beginning to speak, it is natural for them to suck their thumbs. Parents with young babies who regularly suck their thumbs probably don’t need to feel overly concerned, so long as fingers are kept clean and the habit is kept in check. For most children, the exploratory stage of thumb sucking ends after just a few short years. Problems with thumb sucking occur when infants grow into young children but the habit has not been resolved.

Dangers of Thumb Sucking

One of the main differences between an infant and a child sucking his thumb is the formation of the mouth and teeth. An infant’s mouth is barely beginning to grow and develop, so sucking a thumb might actually help to stimulate the process. For a child with a mouth full of teeth, however, a thumb-sucking habit might cause some serious problems. As a parent, it can be very important to watch your child carefully to make sure the sucking habit is regulated.

As a child grows and develops, baby teeth begin to fall out. A child sucking his or her thumb during the baby teeth stage may not run any great risks. Our team at Laganis Pediatric Dentistry often sees that once a child has developed his or her permanent teeth, the problems with thumb sucking can become more serious. KidsHealth.org states that children who suck their thumbs beyond the age of four or five might increase their risk of developing an overbite, infections, and other dental problems.

What You Can Do To Help

Parents who want to prevent possible problems for their child would be wise to begin preventive care early on. While you don’t need to be overly concerned about an infant sucking a thumb, it might be a good idea to help your toddler break the habit before permanent teeth begin to show.

• Try to use positive rewards for good behavior instead of negativity or threatening behavior.
• Talk openly with your child about the potential dangers of a thumb-sucking habit.
• Help your child find other productive things to do with the hands as a means of distraction. Playing a game of blocks, for example, might be a great diversion.
• Support and encourage your child while he or she is trying to break the habit.

As children develop, they have many things to learn and to think about. By understanding a few simple facts about thumb sucking, you can help your child develop in a healthy and positive way. If you have any other questions, feel to contact us at our Maple Grove office, or ask Dr. Venetia Laganis during your next appointment!
