Also known as: toothache, sharp tooth pain, dull tooth pain, pain when chewing, pain when biting, pain when brushing

Tooth pain in children can range from mild, occasional discomfort to persistent or severe pain that interferes with eating, sleeping, or daily activities. It may come and go at first, especially when triggered by chewing, temperature changes, or sweets, but can become more constant as the underlying issue progresses. In many cases, children may not clearly explain what they’re feeling — instead, they might avoid certain foods, chew on one side, or become more irritable than usual.

This symptom is often a sign that something deeper is affecting the tooth, such as decay, infection, or structural damage. While some causes of tooth pain are minor and easily treated, others can worsen over time if left unaddressed. Untreated dental problems may lead to increased pain, spreading infection, difficulty eating, or even early tooth loss, which can affect speech development and proper alignment of adult teeth. Early evaluation helps identify the cause and allows for more comfortable, conservative treatment.

Possible Causes of Tooth Pain

Tooth pain is commonly associated with:

  • Cavities – Tooth decay creates small holes in the enamel that expose sensitive inner layers of the tooth, often causing pain when eating, drinking, or brushing.

  • Infection or nerve involvement – When decay or injury reaches the inner pulp of the tooth, it can inflame or infect the nerve, leading to more intense, throbbing, or persistent pain.

  • Cracked Tooth – A crack or fracture in the tooth can expose sensitive areas and cause discomfort, especially when biting down or releasing pressure.

  • Food trapped between teeth or gum irritation – Food debris stuck between teeth or along the gumline can create pressure and irritation, leading to localized soreness or tenderness.

Treatments for Tooth Pain

Depending on the cause of tooth pain, treatment may include:

  • Fillings – A filling is used to repair a cavity by removing decayed portions of the tooth and restoring it with a durable material. This seals the tooth, protects the sensitive inner layers, and eliminates pain caused by decay.
  • Crowns – A crown is a custom-made covering that fits over a damaged or weakened tooth. It restores strength and structure while protecting the tooth from further damage, helping relieve pain from cracks, large cavities, or structural breakdown.
  • Baby Root Canals (Pulpotomy, aka Pulp Therapy) – This treatment removes infected or inflamed tissue from inside a baby tooth while preserving the outer structure. It helps eliminate deep, persistent pain and prevents the spread of infection, allowing the tooth to remain in place for proper development.

When to See a Dentist

Consider scheduling an appointment if your child:

  • Has ongoing or worsening tooth pain
  • Experiences pain when chewing or biting
  • Shows signs of swelling or infection
  • Avoids eating or brushing
