Common Pediatric Dental Issues and How to Prevent Them

Kids deal with a lot when it comes to their teeth. Cavities, crooked teeth, and gum problems are just a few things that can show up early. The good news? Most of them can be prevented with good habits and a little help from the dentist.

Let’s break down the most common dental issues in kids and how to stop them before they start.

1. Cavities

Cavities are the most common dental problem in kids. They happen when sugar mixes with bacteria in the mouth. This makes acid, which eats away at the tooth’s surface.

How to prevent cavities:

• Brush teeth twice a day with fluoride toothpaste
  
  

• Limit sugary snacks and drinks
  
  

• Floss once a day
  
  

• Visit your pediatric dentist in Airdrie every 6 months
  
  

• Don’t let kids fall asleep with a bottle of milk or juice
  
  

Even baby teeth need care. Just because they fall out doesn’t mean they don’t matter. Healthy baby teeth help hold space for adult teeth and guide them into place.

2. Tooth Decay from Bottles and Sippy Cups

Some toddlers get cavities from using bottles or sippy cups too much, especially if they’re filled with milk, juice, or other sugary drinks. This kind of tooth decay is often called “baby bottle tooth decay.”

How to stop it:

• Don’t let kids walk around sipping all day
  
  

• Only give water between meals
  
  

• Switch to a regular cup as soon as your child can handle it
  
  

• Clean your baby’s gums before teeth come in and brush once they do
  
  

3. Thumb Sucking

Many kids suck their thumbs or fingers when they’re small. It’s a comfort thing. But if it keeps going past age 4 or 5, it can start to affect the way teeth grow in.

How to help:

• Praise kids when they stop
  
  

• Use gentle reminders during the day
  
  

• Talk to your dentist if it doesn’t stop by age 5
  
  

Some kids might need a mouth appliance if the habit goes on too long. But usually, it gets better with time and support.

4. Teeth Grinding (Bruxism)

Some kids grind their teeth, especially while sleeping. You might hear it or notice their teeth look worn down. This can cause jaw pain or headaches too.

What to do:

• Talk to your dentist if you notice it
  
  

• Sometimes a night guard helps
  
  

• Make sure your child isn’t stressed or anxious
  
  

• Keep a calm bedtime routine
  
  

Most kids outgrow it. But if it’s doing damage, it’s better to treat it early.

5. Early Tooth Loss

Losing baby teeth too soon can lead to crowding or misalignment. This often happens from injury or decay. When a baby tooth comes out too early, the teeth around it can shift into that spot.

How to prevent early tooth loss:

• Keep teeth clean and strong with daily care
  
  

• Use mouthguards for sports
  
  

• See the dentist if your child loses a tooth too early
  
  

Dentists may use space maintainers to keep gaps open until adult teeth come in.

6. Gum Disease

Yes, even kids can get gum disease. Red, swollen gums that bleed during brushing could mean gingivitis—the early stage of gum disease.

How to avoid gum problems:

• Brush and floss every day
  
  

• Teach kids not to rush through brushing
  
  

• Regular dental visits
  
  

• Watch out for bleeding or swelling
  
  

Healthy gums are just as important as healthy teeth. Catching problems early keeps things simple.

7. Crooked Teeth and Bite Problems

Sometimes teeth grow in crooked or don’t line up right. Overbites, underbites, and crowded teeth are pretty common in kids. These can make it harder to chew or speak clearly.

What parents can do:

• Get an early orthodontic checkup (usually by age 7)
  
  

• Keep up with regular dental visits
  
  

• Ask about braces or Invisalign if needed
  
  

The sooner these issues are spotted, the easier they are to fix. Some kids don’t need braces until later, but early checks help plan ahead.

8. Delayed Tooth Eruption

Most kids start getting baby teeth around 6 months and adult teeth around age 6. But some kids fall outside that range. If a tooth is very late to come in, it might be stuck or blocked.

What to look for:

• No teeth by age 1
  
  

• Big gaps where adult teeth should be
  
  

• Baby teeth still in place when adult teeth try to come in
  
  

Your dentist may take an X-ray to see what’s going on. In some cases, a tooth may need help breaking through.

Keeping Your Child’s Smile Healthy

You don’t need fancy tools or tricky routines. The basics really work:

• Brush and floss every day
  
  

• Watch what your child eats and drinks
  
  

• Take your child to the dentist twice a year
  
  

• Ask questions if you see anything odd
  
  

Start early. The earlier you teach kids how to care for their teeth, the easier it is to keep those habits going. Make brushing fun with music or a reward chart. Let them pick their own toothbrush and toothpaste.

Good dental habits now can help your child avoid problems later. A healthy smile means more than just clean teeth—it helps your child feel confident and comfortable.
