How much calcium does my child need?

February 11th, 2026

When you were a kid, your parents may have told you to drink milk to build strong bones and grow tall and strong. Now that you have children of your own, you may hear yourself parroting those instructions you received years ago. Getting enough dairy is essential for young children whose teeth are growing. A child who consumes the recommended daily serving of dairy will develop healthy, strong teeth for the rest of his or her life.

So, which foods are the best in terms of acquiring the right amount of calcium? Milk and other dairy products are excellent sources of calcium. Milk also contains vitamin D, phosphorus, magnesium, and proteins. Magnesium promotes calcium deposits in your enamel, while phosphorus forms a small but important barrier against acidic foods that cause cavities. Vitamin D and protein are used by a child’s body to build bone tissue and maintain dental health.

According to a recent study, the majority of Americans, including children, do not receive enough calcium. In fact, according to the Academy of General Dentistry, only one in five children meets even the minimum standards for calcium consumption. The U.S. Department of Agriculture recommends that children under the age of eight should receive two and a half cups of dairy per day. Children older than eight need three full cups, the same as adult men and women. In addition to milk, eating yogurt is a great way your child can increase his or her dairy consumption. Drinking sugary beverages in place of milk causes cavities and tooth decay.

If your child does not get enough dairy consumption, they run the risk of improper tooth development and other dental health problems. Dr. Venetia Laganis and our team at Laganis Pediatric Dentistry encourage you to monitor your child’s dairy consumption to ensure he or she grows healthy teeth to last a lifetime.

Getting to the Bottom of Chewing Gum Myths

February 4th, 2026

It's a moment many of our patients have experienced. One second you're chewing on a piece of gum, then suddenly you forget to keep chewing and swallow the entire rubbery gob whole! It's at this point you remember your mother warning you as a child that if you swallow gum it will stake a claim and take up residency in your belly for seven years. Dr. Venetia Laganis and our team at Laganis Pediatric Dentistry hate to take all the fun out of the mystery, but the truth is that chewing gum, when swallowed, will enter your stomach and move through your digestive system just like any other piece of food. So, if you ever accidentally swallow a piece of gum, there is no need to worry!

That being said, it's important to know that gum does not have any dietary benefits, so while it’s not exactly harmful to swallow, you still want to avoid swallowing it. If you are an avid gum-chewer, we encourage you to chew sugarless gum, especially if you are wearing braces, because gum with sugar can lead to cavities. Sugarless gum still has the same amount of flavor, but has fewer cavity-causing ingredients. In fact, many brands contain an additive called xylitol, a natural sweetener known to fight cavity-causing bacteria. Xylitol is also known to increase salivary flow as it rinses away plaque and acid.

The fact is, when the bacterium in your mouth breaks down sugar, what’s left behind is acid. This acid eats away at the enamel coating of your teeth, causing holes that we call cavities. Cavities can lead to other long-term mouth problems if they are not treated in time, so it is best to try and avoid overexposing your teeth to too many harmful substances!

If you have any questions about chewing gum, please contact our office. Happy (sugar-free) gum chewing!

Thumb Sucking

January 28th, 2026

Learning to suck their thumbs is one of the first physical skills babies acquire. In fact, ultrasound images have revealed babies sucking their thumbs in the womb! Babies have a natural sucking reflex, and this activity is a normal way for your baby to soothe herself.

If your toddler still turns to her thumb for comfort, no need to worry. Most children give up this habit as they grow, and generally stop completely between the ages of two and four. But what of the child who doesn’t? Should you encourage your child to stop? And when?

When Thumb Sucking Becomes a Problem

After your child turns five, and certainly when her permanent teeth start to arrive, aggressive thumb sucking is something to watch for. This type of vigorous sucking, which puts pressure on the teeth and gums, can lead to a number of problems.

  • Open Bite

Our bites are considered normal when the upper teeth slightly overlap the lower where they touch in the front of the mouth. But with aggressive thumb sucking, teeth are pushed out of alignment. Sometimes this results in a condition called “open bite,” where the upper and lower teeth don’t make contact at all. An open bite almost always requires orthodontic treatment.

  • Jaw Problems

Your child’s palate and jaw are still growing. Aggressive thumb sucking can actually change the shape of the palate and jaw, and even affect facial structure. Again, orthodontic treatment can help, but prevention is always the better option!

  • Speech Difficulties

Prolonged thumb sucking has been suggested as a risk factor for speech disorders such as lisping, the inability to pronounce certain letters, or tongue thrusting.

The consequences from aggressive thumb sucking can be prevented with early intervention. What to do if you are worried?

Talk to Us

First, let us reassure you that most children stop thumb sucking on their own, and with no negative dental effects at all. But if your child is still aggressively sucking her thumb once her permanent teeth have started erupting, or if we see changes in her baby teeth, let’s talk about solutions during an appointment at our Maple Grove office. We can offer suggestions to help your child break the habit at home. There are also dental appliances available that can discourage thumb sucking if your child finds it especially hard to stop.

Work with your Child

  • Be Positive

Positive reinforcement is always best. Praise her when she remembers not to suck her thumb. Make a chart with stickers to reward every thumb-free day. Pick out a favorite book to read or activity you can share.

  • Identify Triggers

Children associate thumb sucking with comfort and security.  If your child turns to her thumb when she’s anxious, try to discover what is bothering her and how to reassure her. If she automatically sucks her thumb when she is bored, find an activity that will engage her. If she’s hungry, offer a healthy snack.

  • Talk about It!

Depending on her age, it might help your child to understand why stopping this habit is important. We are happy to explain, in a positive, age-appropriate way, just how breaking the thumb sucking habit will help her teeth and her smile.

Again, most children leave thumb sucking behind naturally and easily. But if what is a comfort for your child has become a concern for you, please give us a call. Dr. Venetia Laganis will work with you and your child to prevent future orthodontic problems and begin her lifetime of beautiful smiles.

 

Let’s Talk About Fluoride

January 21st, 2026

So much of parenting is a balancing act. Making sure your child has enough play time and enough nap time. Crafting meals that are both healthy and appealing. Making sure every dental product you use is both effective and safe.

While Dr. Venetia Laganis and our team can’t recommend the perfect bedtime story, or tell you why your child just won’t go for that delicious steamed broccoli, we are more than happy to discuss the very best ways to promote healthy, strong teeth. Should fluoride toothpaste be part of your child’s dental routine? For many good reasons, the answer is yes.

Why Fluoride is Important

Our enamel is the strongest substance in our bodies, with the highest concentration of minerals, but it is not indestructible. The bacteria that live in our mouths create acids which attack our enamel. Weakened enamel leads to cavities. Fluoride is a mineral that makes the enamel surface more resistant to these acids, and can actually help our enamel repair itself in a process called “remineralization.” Fluoride helps prevent cavities and makes teeth stronger, and those are benefits that will last your child a lifetime.

Can There Be Too Much of a Good Thing?

Fluorosis is a condition that can sometimes develop when a child has been exposed to too much fluoride while the adult teeth are developing below the gum line. (Around the age of eight, children’s teeth have finished forming and are not at risk.) Fluorosis is not a disease, and doesn’t harm teeth, but can lead to faint streaks in the enamel. While this streaking is usually white and subtle, it can sometimes be darker and more noticeable. Teeth discolored by fluorosis can be treated cosmetically, but prevention is always the best option.

Finding the Perfect Balance

Talk to us about using fluoride toothpaste when your baby’s first teeth start arriving. If a very young child is at risk for tooth decay, we might recommend early use of fluoride toothpaste. And for these small children, younger than the age of three, a small smear of paste (about the size of a grain of rice) is sufficient if needed. Swallowing fluoride products increases the risk of fluorosis, so make sure to use a very small amount of paste.

Because young children can’t understand the concept of rinsing and spitting, you always want to make sure the amount of toothpaste you use is age-appropriate even as they get older.  From ages three to six, a pea-sized dab of toothpaste is enough. Children should not use fluoride rinses or supplements unless recommended, and should be monitored to make sure they spit out fluoride toothpaste or rinses after brushing.

Most drinking water already has natural levels of fluoride, which normally aren’t a problem. If you are concerned about high fluoride levels in your local water, talk to us. If your water has higher levels of fluoride than normal, you can minimize consumption when your baby is young by breastfeeding, using non-fluoridated water for mixing with formula powder or concentrate, or buying prepared formula. If your child is a toddler, don’t add fluoride rinses or supplements unless they are recommended by a dental or medical professional.

Talk to us during your visit to our Maple Grove office about protecting your child’s teeth. We are happy to help you find just the right amount of fluoride to keep young smiles stronger and more resistant to tooth decay. Healthy teeth in a beautiful smile—that’s a perfect balance!
