5 Signs Your Child May Have a Cavity
As a parent, keeping your child’s smile healthy is a top priority. But despite our best efforts, cavities can still develop. Cavities, also known as tooth decay, are one of the most common childhood dental issues. The good news is that catching them early can help prevent more serious problems down the road.
At Sweet Tooth Pediatric Dentistry near Chandler, AZ, we specialize in providing expert dental care for children. Below, we’ll discuss five common signs that your child may have a cavity and why early treatment is essential.

1. Tooth Sensitivity to Hot, Cold, or Sweet Foods
If your child winces when eating ice cream, drinking hot chocolate, or enjoying a sugary treat, it could be a sign of a cavity. Cavities weaken the enamel, exposing the more sensitive inner layers of the tooth. This can lead to discomfort when consuming certain foods or drinks. If your child frequently complains about sensitivity, it’s time for a dental check-up.
2. Persistent Toothache or Pain
A constant or intermittent toothache is one of the most obvious signs of a cavity. If your child complains about tooth pain—especially when eating or at random times throughout the day—there could be decay forming inside the tooth. Cavities that go untreated can worsen, leading to infections or the need for more invasive treatments.
3. Visible Holes or Dark Spots on the Teeth
Cavities often start small but can grow larger if left untreated. If you notice brown, black, or white spots on your child’s teeth or visible holes, these could be signs of decay. Regular dental check-ups help catch cavities early before they become more severe.
4. Bad Breath or a Bad Taste in the Mouth
Persistent bad breath that doesn’t improve with brushing and flossing could indicate an underlying dental problem, including cavities. When decay progresses, bacteria build up in the affected tooth, leading to a foul smell or unpleasant taste. If your child has chronic bad breath, a dental exam can determine if a cavity is the cause.
5. Avoiding Chewing on One Side of the Mouth
If your child starts chewing food on only one side of their mouth or avoids certain foods altogether, it may be because they are experiencing pain from a cavity. They may not always vocalize their discomfort, so pay attention to changes in eating habits.
Why Early Cavity Detection Matters
Cavities don’t go away on their own. If left untreated, they can grow larger, affect surrounding teeth, and even lead to infections. Early treatment prevents complications, reduces the need for more invasive dental procedures, and ensures your child’s smile stays healthy.
At Sweet Tooth Pediatric Dentistry, we believe prevention is key! Regular check-ups allow us to detect cavities early and provide gentle, effective treatment.
