What Are the Early Warning Signs of Cavities in Children?

Drs. Nicolas & Asp18 Apr 2024

A child's bright smile is a joy to behold. But cavities, also known as tooth decay or dental caries, can threaten the health of those tiny teeth. Fortunately, catching cavities early can minimize damage and ensure a lifetime of good oral health for your child.

The American Dental Association (ADA) and the American Academy of Pediatric Dentistry (AAPD) and the Dubai Health Authority (DHA) recommend regular dental checkups starting at age one. But how can you spot potential trouble in between visits? Here's what to watch out for:

Most Common Visible Signs of Cavities

Chalky, white spots on the teeth: These are early signs of demineralization, where tooth enamel begins to break down and weaken. These spots are typically seen near the gum, especially on newly erupted teeth, and may turn yellow or brown as decay progresses.
Yellow, dark brown or black spots: These spots or bands on the tooth surface closest to the gum line can indicate a more advanced cavity that requires prompt treatment.
Visible pits, holes, or cracks: The breakdown of the enamel can lead to holes in your child’s teeth referred to as “cavities”.

Common Symptoms of Cavities

The symptoms of cavities vary from one child to another. Early cavities don’t always show symptoms until the dentist finds it, but your child may feel:

Sensitivity: Children may complain about tooth sensitivity to hot, cold, or sweet food and drinks.
Pain and discomfort: Persistent toothaches are a significant sign of a cavity that needs attention from a pediatric dentist.
Difficulty chewing: If your child avoids chewing on one side of their mouth or seems to struggle with hard foods, it could indicate a painful cavity.
Changes in eating habits: A loss of appetite or pickiness with food choices could be related to discomfort caused by a cavity.
Bad breath: Persistent bad breath (halitosis) can be a sign of poor oral hygiene or a developing cavity.

Early Intervention is Key

If you notice any of these signs, schedule an appointment with your child's pediatric dentist. Early detection and treatment can prevent cavities from worsening and potentially causing pain or infection.

Our pediatric dentists recommend brushing with a small amount of fluoride toothpaste twice a day for two minutes, daily flossing, and regular check-ups and cleaning appointments to help keep your child's smile healthy and cavity-free.
