5 Sneaky Habits That Hurt Your Child’s Smile (And How to Break Them)

As parents, we do our best to keep our kids healthy and smiling. But did you know that some everyday habits might be damaging your child’s teeth without you even realizing it? At Doctor Sugar Pediatric Dentistry in Paradise Valley, AZ, we help families spot these subtle risks early—and teach practical ways to turn them into smile-friendly habits.

Here are five common behaviors that could be affecting your child’s oral health and what you can do to protect their growing smile.

1. Sipping Sugary Drinks Throughout the Day

Why it hurts:
Juice, flavored milk, and even sports drinks contain sugars that feed cavity-causing bacteria. When children sip on these throughout the day, their teeth are under constant sugar attack.

What to do instead:
Encourage water between meals. Offer sugary drinks only at mealtimes, and if your child still uses a bottle or sippy cup, try transitioning to a regular cup around 12 to 18 months.

2. Falling Asleep with a Bottle or Sippy Cup

Why it hurts:
Milk or juice at bedtime coats the teeth in sugar, which can lead to early childhood tooth decay, especially when left overnight.

What to do instead:
Only offer water at bedtime. If your child is used to a bottle for comfort, try gradually diluting the milk with water until it's just water.

3. Thumb Sucking or Pacifier Use Beyond Age 3

Why it hurts:
Long-term thumb sucking or pacifier use can change the shape of your child’s mouth and interfere with proper tooth alignment.

What to do instead:
Use positive reinforcement, praise, and small rewards when your child avoids the habit. If it persists beyond age 3, talk to your pediatric dentist for guidance. Early intervention is key.

4. Using Teeth as Tools

Why it hurts:
Kids sometimes use their teeth to open packages, chew on pencils, or bite fingernails. These habits can lead to chips, cracks, and long-term wear.

What to do instead:
Teach children that teeth are for eating, not for opening or biting things. Offer alternatives like safe fidget tools or chewy toys to help redirect the habit.

5. Frequent Snacking (Even on “Healthy” Foods)

Why it hurts:
Constant snacking—even on sticky foods like dried fruit or starchy snacks like crackers—keeps the mouth in a constant state of acid exposure, which can lead to cavities.

What to do instead:
Encourage set meal and snack times, and choose foods that are less likely to stick to teeth, such as cheese, yogurt, and crisp fruits and vegetables. If possible, have your child brush after snacks.
