What to Do If Your Child Has a Toothache

by | Jun 16, 2026 | Parent Education, Special Cases

Few things can disrupt a child’s day faster than a toothache.

Whether the pain appears suddenly or gradually gets worse over time, tooth pain is usually a sign that something needs attention. In some cases, it may be caused by something minor like food stuck between teeth. In other cases, it could signal a cavity, infection, loose tooth, dental injury, or developing abscess.

The good news is that most pediatric dental problems are much easier to treat when caught early.

Here’s what parents should know if their child develops a toothache.

Common Causes of Toothaches in Children

A toothache can happen for many reasons, including:

  • cavities or tooth decay
  • food stuck between teeth
  • loose baby teeth
  • erupting adult teeth
  • gum irritation
  • cracked or chipped teeth
  • dental infections
  • grinding or clenching
  • orthodontic discomfort
  • trauma or injury

Sometimes children have difficulty describing dental pain clearly, so even mild complaints should be taken seriously.

Signs Your Child May Have a Dental Problem

In addition to obvious tooth pain, watch for:

  • swelling around the gums or face
  • sensitivity to hot or cold
  • pain while chewing
  • bad breath
  • fever
  • difficulty sleeping
  • irritability
  • refusing to eat
  • visible holes or dark spots in teeth

Swelling, fever, or facial pain can sometimes indicate an infection and should be evaluated promptly.

What Parents Can Do at Home

If your child develops a toothache, there are several safe first steps you can take before seeing the dentist.

Gently Brush and Floss

Sometimes food debris trapped between teeth can cause irritation or pressure.

Carefully brushing and flossing the area may help relieve discomfort.

Rinse With Warm Salt Water

For older children who can safely rinse and spit, warm salt water may help soothe irritated gums and reduce inflammation.

Use a Cold Compress

If swelling is present, apply a cold compress to the outside of the cheek for short intervals.

Offer Age-Appropriate Pain Relief

Children’s acetaminophen or ibuprofen may help temporarily relieve discomfort if approved by your pediatrician or dentist.

Always follow age and dosing recommendations carefully.

What NOT to Do

Avoid:

  • placing aspirin directly on the gums
  • delaying treatment if swelling is present
  • ignoring persistent pain
  • giving adult medications not intended for children

Even if pain improves temporarily, the underlying issue may still require treatment.

When Should You Call a Pediatric Dentist?

Parents should contact a dentist if:

  • pain lasts more than 1–2 days
  • swelling develops
  • your child has difficulty eating or sleeping
  • there is fever or facial swelling
  • the tooth appears damaged
  • your child complains of significant pain

Dental infections in children can worsen quickly, so early evaluation is important.

Could It Be a Loose Baby Tooth?

Sometimes a “toothache” is actually pressure from:

  • loose baby teeth
  • incoming adult teeth
  • shifting teeth during development

While this can be normal, it’s still a good idea to have persistent discomfort evaluated—especially if swelling or sensitivity is present.

Preventing Future Toothaches

Many childhood toothaches are preventable through:

  • regular dental visits
  • daily brushing and flossing
  • fluoride use
  • healthy nutrition habits
  • early cavity detection
  • preventative dental care

Routine exams allow dentists to identify problems before they become painful emergencies.
