Are thumb sucking and pacifier habits harmful for a child’s teeth?

July 8th, 2026

Depending on how long the thumb sucking or constant pacifier use continues, and how aggressively the child sucks a thumb or the pacifier, it can indeed be an oral health issue. Generally speaking, most children outgrow these behaviors or are able to be weaned off them successfully sometime between ages two and four. When children wean off the behaviors in this age range, long-term damage is unlikely.

Why Kids Suck Their Thumb or Pacifier

Both of these habits are actually a form of self soothing that your child likely uses when he or she is very upset, or feeling stressed, confused, frustrated, or unable to properly express the emotions. If your son or daughters is a regular thumb sucker, or the child wants to use the pacifier almost constantly, it is best to try to taper off these habits at a young age.

If your child continues to suck a thumb or request a pacifier consistently after leaving toddler-hood, this could be a source of concern, and it should be addressed with Dr. Venetia Laganis and our staff. We will be able to evaluate your child's mouth to look for any signs of damage such as palate changes or teeth shifting.

Say Goodbye to Old Habits

In the event that your child is quite reluctant to give up a pacifier or thumb-sucking habit, there are a few things you can do to discourage these behaviors.

  • When you notice that your child is not using a pacifier or sucking a thumb, offer effusive praise. This type of positive reinforcement can be much more effective than scolding the child.
  • Consider instituting a reward system for giving up the habit. If the child goes a certain amount of time without this behavior, award him or her for being such a “big kid.”
  • Employ the help of older siblings or relatives that your child admires. When a child’s role model says that he or she stopped sucking thumbs at a certain age, your child is likely to try to emulate that.

Your Toddler’s First Dental Visit

July 1st, 2026

It’s common for toddlers to be wary of strangers, but their first experience at the dentist shouldn’t be a scary one. Dr. Venetia Laganis and our team have five tips for you to make your child’s first visit to Laganis Pediatric Dentistry easy as pie!

  1. Bringing your child to one of your own appointments before his or her first dental visit can calm your little one’s nerves. This gives your son or daughter the opportunity to get familiar with our office and see a cleaning isn’t very scary.
  2. Our big dental chair can be fun! Toddlers love games, and seeing the chair go up and down can make it seem like an amusement ride rather than sitting down for an exam.
  3. Dr. Venetia Laganis and our team hand out cool toothbrushes and stickers to kids after their appointment. Your child will love the fun-colored toothbrush and can look forward to a post-appointment prize at the next visit.
  4. Schedule your appointment for a time that sets you up for success. Bringing your child to our Maple Grove office an hour before he or she is due for a nap may be a tantrum just waiting to happen.
  5. Kids love books! Try reading your toddler bedtime stories about what happens at the dentist before you come in for the appointment. We recommend Dora the Explorer’s Show Me Your Smile, written by Christine Ricci.

Just What Is a Cavity, Anyway?

June 24th, 2026

The grownups in your life encourage you to brush and floss, eat healthy foods, and visit us in the dental office for exams and cleanings. Why? Because we all want to help you prevent cavities.

So you might be wondering, just what are cavities? How do we get them? What do they do to our teeth? How can we prevent them? Let’s talk!

Our teeth need to be strong to bite and chew. That’s why they are protected by a coating called enamel, which is made up of very hard minerals. Enamel is the strongest part of our bodies—stronger even than our bones. But this doesn’t mean nothing can hurt it! And cavities, also called tooth decay, are one of the most common dangers facing our enamel.

So, what are cavities?

A cavity is a hole in your tooth enamel. If your tooth is not cleaned and repaired when a cavity is small, this hole can grow bigger until tooth decay reaches the inside of your tooth. Enamel doesn’t heal when it’s damaged, so you need to see a dentist to make your tooth healthy again.

How do we get cavities?

Bacteria are tiny little germs. Many kinds of bacteria live in our bodies, and some of them are quite helpful. The bacteria that cause cavities are not. These unhelpful bacteria join with our saliva and very small pieces of the food we’ve chewed to make a sticky film called plaque.

Like other living things, the bacteria in plaque need food. They get that food from the foods we eat, especially sugars and starches. As they eat, they change these sugars and starches into acids, and these acids attack the minerals that keep enamel hard and strong.

Because plaque sticks to our teeth, bacterial acids are able to make weak spots in enamel if the plaque isn’t brushed away. If you see a white spot on your tooth, which could mean that your enamel is losing minerals, and getting weaker.

What do cavities do to our teeth?

Over time, weak spots can grow bigger until there’s a hole in the enamel surface. If the cavity in your enamel is small, you might not notice it at first. But cavities can become wider and deeper, and even break through enamel to reach the inside of your tooth.

The inside of each tooth holds pulp, the part of your tooth that keeps it healthy. If tooth decay spreads to the pulp, it can cause more damage and infection, so it’s important to treat a cavity right away.

Dark spots on your enamel, a toothache, pain when you drink something hot or cold or when you bite down—these can be clues that you have a cavity, and you should visit us for an exam.

How can you prevent cavities?

Even better than treating a cavity is preventing one. Let’s make a list of some helpful do’s and don’ts for cavity prevention:

  • Do: Feed yourself foods that are good for you.

Foods like milk and cheese and many dark green vegetables have lots of calcium and vitamin D to help keep your enamel strong.

  • Don’t: Feed bacteria foods that are good for them.

Sugar and simple starches like potato chips are the kinds of foods bacteria like best, because they are easy to break down. This means more acids to attack your enamel.

This doesn’t mean you should never enjoy a treat! But eating lots of starchy snacks and drinking sugary sodas means more plaque, and more plaque can mean more cavities. If you’re eating something starchy or sweet, it’s a good idea to brush or rinse afterward.

  • Do: Brush at least twice a day, for at least two minutes, with fluoride toothpaste.

This is the best way to get rid of plaque, which builds up every day. And fluoride toothpaste even helps make your enamel stronger.

  • Don’t: Forget to floss.

Flossing takes a while to learn to do well, but it’s very important. Flossing helps prevent cavities between the teeth and near the gums.

  • Do: Visit our Maple Grove office for exams and cleanings.

Not only will we look for cavities, we’ll let you know the best way to brush and floss so you can get your teeth their cleanest. We even have special coatings called sealants that can protect your teeth from plaque.

  • Don’t: Feel bad if you get a cavity!

Some people are more likely to get cavities than others, even when they brush just right and eat healthy foods. If you have a cavity, we can remove decay and repair your tooth with a filling.

And one last thing to do: talk to Dr. Venetia Laganis if you have any questions about the best ways to protect your teeth from cavities. We have lots of suggestions to help you take care of your healthy, beautiful smile!

Avoid Brushing After Every Single Meal!

June 17th, 2026

Here is some surprising yet worthwhile advice you might be hearing for the first time: Brushing can be incredibly bad for your child’s teeth if done right after eating certain foods.

Enamel is an extremely hard mineral on the exterior of each tooth. It’s actually the hardest substance in the human body: It’s even stronger than bones! Its only weakness is that acids in the food we eat can easily destroy enamel.

Healthy teeth thrive in an environment that has the proper pH balance. That ensures the mouth doesn’t start the process of demineralization—the process when alkaline turns into acid, which attacks and softens the enamel on the surface of your child’s teeth. Pores and fissures form, and that’s when the harmful bacteria go to work.

A mouth’s pH level fluctuates depending on what is eaten throughout the day. Examples of the most common highly acidic foods include citrus fruits, soda, and sugary foods. Highly acidic foods tip the balance of pH in the mouth from a healthy alkaline to a dangerous acid.

Can brushing your child’s teeth immediately after a meal lead to even more damage? The answer is yes!

Eating highly acidic foods causes your child’s teeth to be more susceptible. If your child brushes when the teeth have been weakened by acids, even more destruction can happen to the enamel. Your child’s toothbrush bristles will actually wear away some of the enamel. So it’s healthier for your child to wait at least an hour after eating or snacking to brush.

Good preventive measures to take instead of brushing after your child eats include:

  • Rinsing or drinking water
  • Chewing sugarless gum
  • Consuming dairy or non-acidic foods to conclude a meal

These practices help produce saliva, which in turn restores a healthy pH level in your child’s mouth and coats the teeth with minerals they need.

Once your child’s mouth is restored to a healthy pH level, he or she may brush normally. Keep in mind that acidic foods can weaken the enamel on the teeth and take the right measures to prevent spiking pH levels.
