Shark Teeth

May 13th, 2026

It seems like sharks are everywhere these days—on land, sea, and air(waves). A halftime show meme gone viral. A week of summer TV devoted to our favorite apex predators. And who doesn’t have “Baby Shark” playing in their heads all day once they’ve heard it? But are we jumping the shark to discuss this topic in a dental blog?

Not at all! Because today, we’re going to talk about shark teeth—just not the ones you might be expecting.

One of the expected sights when a shark opens its mouth are those rows and rows of shiny shark teeth. Sharks can grow from two to 15 rows of teeth at any one time (and some sharks have even more). This means sharp new teeth are always ready to replace any shark tooth which is lost, broken, or worn out.

An unexpected sight? When children point to their new adult tooth or teeth coming in—right behind their still-firmly rooted baby teeth! This double set of teeth is called “shark teeth,” and, while it certainly might come as a surprise, it’s not all that uncommon. But why do children develop shark teeth at all?

After all, baby, or primary, teeth have small roots, and are designed to come out easily when the adult teeth start arriving. When a permanent tooth starts to erupt, it pushes against the root of the baby tooth above it. This pressure gradually dissolves the root of the primary tooth, and with nothing to anchor it, it’s now loose, wiggly, and ready to fall out. That’s why baby teeth often look like they have no roots at all when they eventually wiggle free.

Sometimes, though, the roots of a primary tooth don’t break down, which means baby teeth stay right where they are. It also means that the permanent teeth have to erupt somewhere else—usually behind those stubborn little baby teeth.

Shark teeth can first appear around the ages of five to seven when the permanent front teeth start arriving, or several years later, when the adult molars begin to come in. Any extra teeth in one small jaw naturally cause concerns about crowding and misalignment, especially when those extra teeth are molars. Fortunately, treatment is generally uncomplicated.

If the baby tooth is loose, time (and wiggling) might take care of the problem. But if the primary tooth or teeth just won’t budge, even after several weeks, it’s a good idea to schedule a visit with Dr. Venetia Laganis—especially if your child is experiencing pain or discomfort.

An extraction is often suggested when a baby tooth has overstayed its welcome. Because of its smaller root, extracting a primary tooth is usually a straightforward procedure. Dr. Venetia Laganis can let you know all the details, and can discuss sedation options if they’re appropriate for your child.

Whether baby teeth are left to fall out on their own, or given some assistance, most often your child’s permanent tooth will start moving to its proper position as soon as the space is available.

Unlike sharks, we don’t have an endless supply of replacement teeth, so it’s understandable to worry when you see anything unexpected. If you want to know more about shark teeth, or if you have any concerns, don’t hesitate to call our Maple Grove office for expert advice.

Periodontal Disease in Adolescents

May 6th, 2026

Dr. Venetia Laganis and our team at Laganis Pediatric Dentistry know that periodontal disease isn't something exclusive to adults. It can affect adolescents as well. Gingivitis, which is a milder form of periodontitis, is a form of periodontal disease, and a warning that more serious problems may arise. Untreated gingivitis can develop into full-blown periodontitis.

The American Academy of Periodontology (AAP) explains that research proves that younger people may develop more severe forms of gingivitis. Gingivitis is linked to periodontal disease. Children and adolescents who have type 1 diabetes or immune deficiencies are more likely to suffer from periodontal disease.

There are three types of periodontal diseases Dr. Venetia Laganis and our team see in children and adolescents.

Chronic gingivitis

Parents may suspect that their adolescent has chronic gingivitis if he or she shows or complains of symptoms such as redness, swelling, or bleeding gums. Early treatment may prevent gingivitis from developing into a more severe form of periodontal disease.

Aggressive and/or chronic periodontitis

Once called adult periodontitis, the term chronic replaces “adult” because periodontitis can occur in people in their early teenage years, and progress throughout their teens. Chronic and aggressive periodontitis primarily affects incisors and first molars. One of its distinguishing characteristics is bone loss. Curiously, patients who suffer from this form of the disease have minimal dental plaque on examination.

Generalized aggressive and chronic periodontal disease

This form of periodontal disease has many of the same characteristics of the chronic and aggressive form, but this more severe type of the disease affects the entire mouth. Symptoms include major plaque and calculus accumulation, and inflamed gums.

In both forms of more severe periodontal disease, the overall gum structure may change. The severity of these changes may alter gum strength enough to loosen teeth, or even worse, cause them to fall out.

The success of any treatment is largely contingent on early diagnosis. Dr. Venetia Laganis should conduct a thorough periodontal exam as part of an adolescent’s twice-yearly complete dental examinations.

The mouth is full of bacteria. Some of it is necessary for food digestion. Diseases are more likely to develop if bacteria travel to open places in the mouth, such as exposed gum pockets or cavities. Proper dental hygiene is essential for a healthy mouth, and a healthy mouth offers greater protection against painful dental diseases.

Be sure every member of your family has a complete dental exam and cleaning twice a year, and contact Dr. Venetia Laganis when you or your young kids or adolescents complain of pain, sensitivity, or other oral problems. Early detection at our Maple Grove office leads to treatment of oral problems and prevents them from turning into serious periodontal disease and potentially irreversible problems.

How to Brush a Two-Year-Old’s Teeth Effectively

April 29th, 2026

Our team at Laganis Pediatric Dentistry would like to offer some tips regarding the sometimes dreaded task of brushing a toddler’s teeth.

Much of the trick lies in the positioning. Before you begin, make sure you are in a position of control. This protects both you and your child from injury. Consider how well you can see. If you cannot see clearly, the quality of brushing drops significantly. For instance, if your child is standing, you are likely to see only the bottom teeth well.

Our team finds that the best position for brushing and flossing a toddler is when your child is calm. Have your child lie down on his or her back with arms out to make a T. Sit down just above the head and lightly place your legs over your child’s arms. Using a circular motion, brush all sides of the teeth.

It may sound odd, but approaching the routine this way can make brushing time a cinch! After you’re done, give your child the toothbrush and let him or her have a turn. The benefit of doing the brushing and flossing first is that it gives an example, which your child is more likely to repeat when you’re done.

Different methods work best for different families and children. These practices need to be performed with kindness and care. Be gentle and make this time a happy learning time. Don’t forget to bring your child to our Maple Grove office for regular dental checkups and cleanings. Dr. Venetia Laganis can advise you on ways to implement portions of these tips in a way that may work bests for you and your child.

When should my child start using toothpaste and how much should I use?

April 22nd, 2026

As a parent, it is your job to instill good dental habits in your kids, and this starts even earlier than you might realize. The American Academy of Pediatric Dentistry responds to the “when to start” question with a succinct “The sooner the better!”

From the time your baby is born, you should make sure that your child’s gums are regularly cleaned using water and a toothbrush made for infants. Once the first tooth erupts, you should visit the pediatric dentist for the first time. Dr. Venetia Laganis and our staff often recommend that if your child is a year old, but has yet to get the first tooth, you should bring your son or daughter to our Maple Grove office for his or her initial dental care appointment.

Once your child’s teeth start to appear, you can begin brushing two times per day, using fluoride toothpaste. Choose a toothbrush made specifically for your child’s age group, and one with has soft bristles.

Only a small smear of toothpaste is needed if your child is under two years old. Once the child celebrates his or her second birthday, you can use a pea-sized amount of fluoridated toothpaste. Continue this practice until your child is five.

Of course, it is important that you monitor your child’s tooth brushing closely to help educate about proper techniques. Some young children might try to eat or swallow toothpaste, and this needs to be strongly discouraged. Be sure to teach proper rinsing and spitting behavior to round out your child’s early childhood tooth-care regimen.

For young kids, tooth brushing can be made into a fun event, and you can find a multitude of special toothbrushes that appeal to kids. There are even uniquely flavored and colored toothpastes that might encourage your child to get into the brushing game!
