Backpacks are packed, school supplies are ready, and the morning routine is officially back in action. But before your child gets fully immersed in another busy school year, there’s one more thing worth checking: their smile.

Children’s teeth can change quickly, and some dental concerns aren’t always obvious to parents—or to kids. A quick look at your child’s teeth and mouth can help you spot potential problems early and determine whether it’s time for a dental visit.

Here are six things parents should look for as the school year gets underway.

1. Tooth Sensitivity

Does your child suddenly complain that a cold drink, ice cream, or certain foods make their teeth hurt?

Occasional sensitivity can happen for different reasons, but recurring or unexplained discomfort shouldn’t be ignored. Sensitivity may be associated with cavities, enamel wear, dental injuries, or other oral health concerns.

If your child consistently avoids certain foods or drinks because their teeth hurt, it’s worth having their smile evaluated.

2. Loose, Chipped, or Damaged Teeth

A loose baby tooth can be completely normal, especially when it’s close to falling out. However, not every loose tooth is part of the normal tooth-loss process.

Check for teeth that appear chipped, cracked, unusually loose, or discolored. Children may damage their teeth during summer activities, sports, falls, or everyday play without mentioning it.

If a tooth looks different after an injury—or your child complains of pain when biting or chewing—a dental evaluation can help determine whether treatment is needed.

3. Plaque Buildup

Summer schedules can make it easy for brushing and flossing routines to slip. Once school starts, take a closer look at your child’s teeth.

Plaque may appear as a soft, sticky film along the teeth, particularly near the gumline and around areas that are difficult to reach. Persistent plaque buildup can increase the risk of cavities and gum inflammation.

This is also a good opportunity to check whether your child is brushing thoroughly or simply rushing through the routine.

Younger children often still need help with brushing, even if they insist they can do it themselves. Parents can encourage independence while continuing to supervise and assist as needed.

4. Mouth Sores or Irritation

Take a quick look inside your child’s mouth for sores, unusual redness, swelling, or areas that appear irritated.

Many mouth sores are temporary and resolve on their own. However, sores that are persistent, painful, recurring, or accompanied by swelling or other symptoms should be discussed with a dental professional.

Children don’t always recognize or communicate changes in their mouths, so a routine check can help parents notice something they might otherwise miss.

5. Changes in Their Bite

As children grow, their teeth and jaws continue to develop. Pay attention if your child suddenly says that their bite feels different or if you notice changes when they close their mouth.

Watch for difficulty chewing, discomfort when biting, teeth that appear to be shifting, or changes in how the upper and lower teeth come together.

Not every change requires treatment, but monitoring your child’s developing bite allows a pediatric dentist to identify concerns and determine whether they need attention.

6. Bad Breath That Doesn't Go Away

Morning breath happens. Persistent bad breath, however, can be a sign that something needs more attention.

Poor brushing, plaque buildup, food trapped between teeth, gum irritation, or other oral health issues can contribute to ongoing bad breath. If your child’s breath remains unpleasant even with consistent brushing and good oral hygiene, a dental checkup can help identify the cause.

A Back-to-School Checkup Can Start the Year on the Right Foot

The start of the school year is a natural time to get back into healthy routines—and that includes dental care. Regular pediatric dental visits give your child’s dentist an opportunity to monitor developing teeth, identify potential concerns early, reinforce good oral hygiene habits, and help keep small problems from becoming bigger ones.
