Tooth Pain at Night: Why Your Child Wakes Up With a Toothache and What Parents Should Do
Few things are more upsetting for a parent than hearing, “My tooth hurts,” in the middle of the night. A child who wakes up with a toothache may be experiencing something minor, such as food stuck between their teeth, or something that needs prompt attention, such as a cavity or dental infection.
So, why does tooth pain sometimes seem worse at night? And what should parents do when their child wakes up crying because of a toothache?
Understanding the possible causes can help you know when to monitor the pain, when to call your pediatric dentist, and when your child may need urgent dental care.
Why Does My Child’s Tooth Hurt More at Night?
Tooth pain can happen at any time, but many children notice it more at bedtime or during the night. One reason is that there are fewer distractions when your child is lying quietly in bed. A mild ache that was easy to ignore during the day can suddenly feel much more noticeable.
Changes in blood flow and pressure when lying down may also make inflammation around a tooth feel more uncomfortable. If your child already has an irritated or infected tooth, nighttime can make the discomfort seem especially intense.
Most importantly, repeated nighttime tooth pain should not simply be ignored. It can be a sign that your child needs a dental examination.
Common Causes of Nighttime Tooth Pain in Children
1. Cavities
One of the most common causes of tooth pain in children is tooth decay. Cavities develop when bacteria in the mouth use sugars from food and drinks to produce acids that gradually damage the tooth.
Early cavities may not cause any symptoms. As decay progresses deeper into the tooth, however, your child may develop sensitivity or pain, particularly when eating or drinking something hot, cold, sweet, or acidic.
If your child is waking up because of tooth pain, a cavity is one possibility your pediatric dentist will want to rule out.
2. A Dental Infection
A cavity that reaches the inner part of the tooth can sometimes lead to an infection. An infected tooth may cause persistent or throbbing pain that becomes difficult for a child to ignore.
Parents should pay particular attention to symptoms such as:
Persistent or severe tooth pain
Swelling around the tooth or face
Red or swollen gums
Fever
Pain when biting or chewing
A bad taste or drainage in the mouth
Difficulty opening the mouth
These symptoms require prompt dental attention.
3. Food Stuck Between the Teeth
Sometimes the explanation is much simpler. A small piece of food can become trapped between teeth and irritate the gums, creating localized discomfort.
If your child says one particular area hurts, gently flossing between the teeth may help remove trapped food. However, avoid aggressively poking around a painful tooth or gum.
If the pain continues after the area is cleaned, schedule a dental evaluation.
4. Tooth Sensitivity
Children can experience tooth sensitivity for several reasons. A developing cavity, enamel wear, gum irritation, or certain dental treatments can make a tooth more sensitive to temperature.
If your child consistently complains that a tooth hurts when drinking something cold or eating something sweet, mention this pattern to your pediatric dentist.
5. A Loose Baby Tooth
Sometimes a loose baby tooth can cause tenderness, especially if your child has been touching or wiggling it frequently.
A little discomfort can be normal as a baby tooth prepares to fall out. Significant, persistent, or worsening pain is different and deserves a closer look.
6. Tooth Grinding or Clenching
Some children grind or clench their teeth while sleeping. This can put extra pressure on the teeth and jaw and may contribute to morning tooth or jaw discomfort.
If you notice grinding sounds at night, frequent jaw soreness, headaches, or worn-down teeth, bring it up during your child's next dental visit.
What Should Parents Do When a Child Wakes Up With Tooth Pain?
First, stay calm. Your child may already be frightened or uncomfortable, and reassurance can help.
You can:
Look inside your child's mouth. Check for obvious swelling, redness, food stuck between teeth, or a damaged tooth.
Gently clean the area. Brushing and flossing carefully can help remove food or plaque that may be irritating the gums.
Offer water. Keeping your child hydrated is helpful, and rinsing gently with water may remove food particles.
Use a cold compress. If there is swelling, a cold compress applied to the outside of the cheek for short periods may help with discomfort.
Consider an appropriate children's pain reliever. If your child can safely take an over-the-counter pain medication, follow the product's age/weight dosing instructions or your pediatrician's guidance. Never give aspirin to children.
Most importantly, pain relief is not the same as treating the cause. If the tooth continues to hurt, your child should be evaluated by a dentist.
When Is a Child's Toothache a Dental Emergency?
Not every toothache requires an emergency visit, but some symptoms should be taken seriously.
Contact a pediatric dentist promptly if your child has significant or persistent tooth pain, particularly if it is waking them from sleep.
Seek urgent medical attention if your child develops facial swelling that is rapidly increasing, difficulty breathing or swallowing, significant swelling around the eye, or other symptoms suggesting that an infection may be spreading.
When in doubt, it's better to contact your child's dental office and describe the symptoms.
Can You Prevent Tooth Pain at Night?
Good daily dental habits can significantly reduce the risk of many common causes of tooth pain.
Encourage your child to:
Brush twice a day with fluoride toothpaste.
Floss once a day, especially between teeth that touch.
Drink water regularly.
Limit frequent sugary snacks and drinks.
Avoid putting your child to bed with sugary drinks.
Visit the pediatric dentist regularly.
Tell an adult about tooth sensitivity or discomfort instead of waiting for the pain to become severe.
Regular pediatric dental visits are particularly important because children can have cavities or other dental problems before obvious pain develops.
Don't Wait for the Toothache to Become a Bigger Problem
A child who wakes up with tooth pain is trying to tell you something. While the cause may be something simple, recurring or severe nighttime toothaches can indicate a cavity, infection, sensitivity, or another dental problem that needs attention.
If your child in Paradise Valley, AZ, is experiencing persistent tooth pain, a pediatric dentist can examine the tooth, identify the cause, and recommend the appropriate treatment.

Frequently Asked Questions
Why does my child's tooth hurt only at night?
Tooth pain may become more noticeable at night because there are fewer distractions and lying down can make discomfort associated with inflammation feel more pronounced. Recurring nighttime pain should be evaluated by a dentist.
Should I take my child to the dentist for a toothache?
If the pain is persistent, severe, wakes your child from sleep, or is accompanied by swelling, fever, or other symptoms, contact your pediatric dentist.
How can I help my child's toothache at night?
Gently clean the teeth, check for food trapped between them, offer water, and use a cold compress if there is swelling. An age- and weight-appropriate children's pain reliever may also be used according to the label or your child's healthcare provider's instructions. These measures can provide temporary relief but do not treat the underlying dental problem.
Can a cavity cause nighttime tooth pain?
Yes. As tooth decay progresses deeper into a tooth, it can cause sensitivity and persistent pain. A dental examination is needed to determine whether a cavity is responsible.
Is nighttime tooth pain a sign of a dental emergency?
It can be, particularly when severe pain is accompanied by facial swelling, fever, difficulty swallowing or breathing, or swelling around the eye. These symptoms require prompt professional attention.
