My Kid Has a Toothache but the Dentist Says Nothing’s Wrong: What Do I Do?

Reading time: three minutes

Your child is complaining about a toothache, but the dentist says everything looks fine. Now what?

It’s frustrating when there’s no clear answer, but not all tooth pain comes from cavities or infections. From growing pains to sinus pressure, several factors can cause discomfort. 

Here’s what might be going on—and what you can do to help.

Common Dental Causes of Unexplained Toothaches in Kids

Even if no cavities or injuries are found, these dental issues might be lurking:

1. Tooth sensitivity: Triggered by cold foods, hot drinks, or sweet foods, sensitivity arises when the protective layer of enamel wears down, exposing nerve endings.
2. Gum inflammation: Food particles trapped between teeth or inadequate brushing can cause gum infections, leading to red and tender gums.
3. New teeth erupting: Emerging permanent teeth or wisdom teeth (in teens) can create pressure and discomfort.
4. Sinus infection: Sinus congestion from infections often mimics upper teeth pain, as sinus cavities sit close to tooth roots.

When It’s Not the Teeth: Surprising Non-Dental Causes

Sometimes, pain originates elsewhere but feels like a toothache. Key culprits include:

• Ear infections: Pain may radiate to the jaw, mimicking dental pain.
• TMJ disorders: Jaw joint issues (temporomandibular joint) can lead to jaw pain, headaches, and toothaches.
• Trigeminal neuralgia: Irritation of facial nerves may cause sharp, shooting pains mistaken for toothaches.
• Headaches/migraines: These can refer to pain in the teeth or jaw.
• Teeth grinding (bruxism): Stress-related grinding wears down enamel and strains jaw muscles.
• Anxiety: Emotional stress can manifest as sensitivity or facial pain.

What Parents Can Do at Home

1. Track symptoms: Note the type of pain (sharp, constant), timing, and triggers (extreme temperatures, chewing).
2. Optimize oral hygiene: Use a soft-bristled toothbrush and fluoride or hydroxyapatite toothpaste to protect against gum recession and decay.
3. Adjust diet: Avoid acidic foods and sugary snacks; offer soft foods if chewing hurts.
4. Temporary relief: Over-the-counter pain relievers (like ibuprofen) or a cotton ball with clove oil (use cautiously) can soothe discomfort.

When to Revisit the Dentist or See a Specialist

Return to the dentist if pain persists or worsens, or if swelling, fever, or bad breath develops. If dental exams and X-rays rule out issues, consult:

• ENT specialist: For sinus or ear infections.
• Pediatrician: To rule out systemic medical conditions.
• Neurologist: For nerve-related pain like trigeminal neuralgia.
