What Causes Cavities?

Cavities form when children’s teeth are frequently exposed to sugary foods and carbohydrates (such as those in candy, juice, or white bread). After eating, these sugars cling to teeth and combine with bacteria in the mouth to create a sticky film called plaque. The bacteria in plaque feed on sugar and release acid, which attacks and weakens the enamel. Over time, the acid can penetrate deeper into the tooth, causing decay and cavity formation.

Although primary (baby) teeth eventually fall out, they play an essential role in speech, chewing, and guiding permanent teeth into position. Protecting them is crucial. Daily brushing and flossing (at least twice a day), along with regular dental cleanings, are key to cavity prevention. Pediatric dentists may also apply sealants or prescribe fluoride treatments to strengthen teeth and reduce the risk of decay.

How Will I Know if My Child Has a Cavity?

Large cavities can cause severe pain, while small ones may not cause any noticeable symptoms. Cavities can also form between teeth, making them difficult to detect without a dentist’s help. Digital X-rays and a professional dental exam are often needed to identify early cavities before they worsen.

Common Symptoms of Cavities in Children:

  • Heightened sensitivity to hot, cold, or sweet foods
  • Nighttime waking and crying due to pain
  • Toothache or persistent discomfort
  • Sensitivity to spicy foods
  • Swelling of the gums or face near the tooth

If your child experiences any of these symptoms, schedule a visit with a pediatric dentist promptly. Early treatment helps prevent further damage, reduces pain, and can save teeth that might otherwise be lost.
