For a child’s toothache, rinse with warm water, gently floss around the sore tooth and hold a cold compress on the cheek. Give a children’s pain reliever dosed for their age, then call your pediatric dentist, since most toothaches need treatment.
A toothache in a child can come from something as small as a popcorn hull stuck in the gums or something as serious as an infected tooth. The tricky part is that young children are not great at describing pain. They may say their ear hurts, refuse to chew on one side, or simply be cranky at bedtime. This guide walks through the common causes, safe relief at home, the signs that need same-day care and what our team in Fairhope does to fix the problem.
What Causes a Toothache in Kids?
Most toothaches in children trace back to one of a handful of causes. Knowing which one you are dealing with helps you decide how quickly your child needs to be seen.
Cavities
Tooth decay is the most common cause. Early cavities often do not hurt at all, so by the time a child complains, the decay has usually reached the softer layer underneath the enamel or is getting close to the nerve. Pain that comes on with sweets or cold drinks is a classic sign.
Food stuck between teeth or in the gums
A wedged piece of food can press on the gums and cause surprisingly sharp pain. This one is easy to fix at home with gentle flossing and a rinse, and the pain should ease within a day.
A cracked or chipped tooth
Falls, sports and hard foods can crack a tooth without an obvious chip. Pain when biting down or sensitivity that lingers can point to a crack. If you can see the damage, our guide on what to do when your child chips a tooth has step-by-step instructions.
New teeth coming in
Erupting molars can make the gums sore, especially the first permanent molars around age 6 and the second molars around age 12. The discomfort is real but usually mild, and it comes with swollen gums at the back of the mouth rather than pain in one specific tooth.
An infection or abscess
When decay reaches the nerve, the tooth can become infected. Watch for throbbing pain, swelling of the gums or face, a pimple-like bump on the gum, a bad taste or a fever. An infected tooth needs prompt treatment and will not get better on its own.
Grinding or sinus pressure
Children who grind at night can wake up with sore teeth or jaws, and a sinus infection can make the upper back teeth ache. If your child grinds, our post on nighttime teeth grinding explains what to look for.
How Can You Relieve Your Child’s Toothache at Home?
These steps can make your child more comfortable while you arrange a visit. They ease pain, but they do not treat the cause.
- Rinse. Have your child swish warm water, or warm salt water if they are old enough not to swallow it.
- Floss gently. Remove any food caught around the sore tooth.
- Cold compress. Hold a wrapped ice pack against the cheek for short periods to calm swelling.
- Pain reliever. Give a children’s pain reliever following the label for your child’s age and weight, or as your pediatrician directs.
- Soft, lukewarm foods. Avoid very hot, very cold, sweet or crunchy foods for now.
What not to do
Never put aspirin or a crushed tablet directly on the gums, because it can burn the tissue. Avoid numbing gels for young children unless your dentist or pediatrician recommends one. And do not wait to see if the pain goes away on its own, since a toothache that fades can mean the nerve is dying, not that the problem is gone.
When Is a Child’s Toothache an Emergency?
Most toothaches should be checked within a day or two. Some need faster attention. Use this as a guide, and when in doubt, call us.
| What you notice | What it may mean | What to do |
|---|---|---|
| Mild pain that started after eating, food visible between teeth | Trapped food | Floss and rinse; call if pain lasts past a day |
| Pain with sweets or cold drinks | Cavity | Call to schedule a visit soon |
| Pain when biting after a fall | Cracked or injured tooth | Call the same day |
| Throbbing pain, gum bump or bad taste | Infection or abscess | Call the same day |
| Facial swelling with fever, or trouble swallowing or breathing | Spreading infection | Go to the emergency room right away |
| Sore gums at the back of the mouth around age 6 or 12 | Molars coming in | Comfort care; mention it at the next visit |
Our patient resources page lists what counts as a dental emergency and what to do in the most common situations, including a knocked-out tooth.
What Will the Pediatric Dentist Do for a Toothache?
The visit starts with finding the cause. We ask when the pain started and what makes it worse, look closely at the tooth and gums and usually take a digital X-ray to see what is happening below the surface. We explain what we find in kid-friendly language and walk you through the options before anything is done.
Treatments we may recommend
- A tooth-colored filling for a small or moderate cavity. Our guide to tooth-colored fillings for kids explains how they work.
- Pulp treatment and a crown when decay has reached the nerve of a baby tooth. Pediatric dental crowns protect the tooth until it is ready to fall out naturally.
- An extraction when a tooth cannot be saved, often followed by a space maintainer. Learn more about tooth extractions for kids.
- Comfort options for anxious children, including sedation when it is appropriate.
You can see the full range of restorative care on our pediatric dental treatments page. Our goal is always to keep the tooth when we can and to make the visit as calm as possible.
How Can You Prevent Toothaches?
Most toothaches are preventable. Twice-daily brushing with fluoride toothpaste, daily flossing once teeth touch, limited grazing on sugary snacks and drinks, and checkups every six months catch problems while they are small and easy to treat. Sealants protect the deep grooves of back teeth, and a mouthguard protects teeth during sports.
Frequently Asked Questions
Why does my child’s toothache get worse at night?
Lying down increases blood flow to the head, which can make tooth pain throb, and there are fewer distractions at bedtime. Propping your child up with an extra pillow and giving a pain reliever before bed can help until the visit.
Can a baby tooth get infected even if it will fall out soon?
Yes. An infected baby tooth can cause pain, swelling and, in some cases, damage to the permanent tooth developing underneath. It should be treated even if it is loose.
My child says their ear hurts. Could it be a tooth?
It can be. Pain from the back teeth can feel like it is in the ear or jaw. If your pediatrician finds no ear infection, have us take a look at the teeth.
Will my child need a shot to fix the tooth?
Many treatments use local numbing, which we apply gently and explain step by step. For children who are very nervous or need more extensive care, we can discuss sedation options with you.
