What Are the Symptoms of Tooth Decay in Children?

March 11, 2024

Tooth decay is a common dental problem that affects people of all ages, including children. It occurs when bacteria and plaque erode the tooth enamel, leading to cavities. And since baby teeth have weaker tooth enamel than permanent teeth, young children are especially prone to tooth decay [1].

Timely detection of tooth decay in children is crucial to prevent further damage and maintain good oral health. So what are the symptoms of tooth decay in children? Here are a few ways parents and caregivers can identify potential issues to seek dental care promptly.

Toothache

A toothache is one of the most noticeable symptoms of tooth decay in children. Your child may experience a persistent or intermittent ache in the affected tooth or teeth, causing discomfort or pain. They may complain of sharp or dull pain that can be aggravated by eating, drinking cold or hot beverages, or applying pressure on the tooth.

Discoloration

Tooth discoloration is another indicator of tooth decay in children. Initially, the affected tooth may develop white spots on its surface, indicating the early stages of decay. As the decay progresses, the discoloration may turn brown, black, or even yellow [2]. It’s important to note any unusual color changes on your child’s teeth and seek dental evaluation as soon as possible.

Pain When Biting

Children with tooth decay may experience pain or discomfort when biting or chewing food. This can be a result of the decay reaching deeper layers of the tooth, exposing nerve endings and causing sensitivity. If your child displays signs of discomfort while eating, especially on one particular tooth or one side of their mouth, it’s time to see the dentist.

Sensitivity to Temperature

Tooth sensitivity is a common symptom of tooth decay in children [3]. If your child experiences sensitivity or a tingling sensation when consuming hot, cold, sweet, or even spicy foods and drinks, it may indicate tooth decay. Sensitivity occurs when the protective enamel is eroded, exposing the tooth’s inner layers to external temperatures.

Bad Breath

Persistent bad breath, also known as halitosis, can indicate tooth decay in children. The bacteria responsible for tooth decay release foul-smelling compounds, contributing to unpleasant breath odor. If your child’s breath consistently smells unpleasant, even after thorough brushing and flossing, it’s essential to have their teeth examined by a dentist.

Visible Holes or Pits

In advanced stages of tooth decay, visible cavities or holes may appear on the affected tooth’s surface [4]. These areas may be accompanied by a discolored or darkened appearance on the tooth. If you notice any visible signs of decay, it’s essential to schedule a dental appointment promptly to prevent further damage and even a tooth infection.

Childhood Tooth Decay Is Preventable

Although your child may have some of the above symptoms with tooth decay, it’s crucial to note that tooth decay typically doesn’t cause symptoms until the cavity has progressed significantly. Therefore, it’s possible that your child has cavities that are not yet painful.

Don’t wait to have your child’s smile evaluated. Childhood tooth decay is preventable with proper oral care at home and regular visits with a pediatric dentist. Contact your child’s dentist today to schedule their next check-up and protect their teeth from decay!
