Are Toothaches Normal for Children?
Yes — toothaches are relatively common in children, especially as they grow and their teeth develop. From erupting baby teeth to cavities or even minor injuries, children can experience dental discomfort for various reasons, including their developing dental hygiene habits, dietary choices, and natural changes in their teeth. While some toothaches are mild and temporary, others may indicate an underlying issue that needs professional attention. Knowing what’s normal and what’s not can help you respond appropriately and prevent minor problems from becoming serious ones.
Causes of Toothache in Children
Several factors can lead to a child’s toothache — some more obvious than others. A study on children aged 10-15 in India found that 17% reported mild pain, 43% moderate pain, and 40% severe pain. Additionally, 66% experienced disruptions to their daily activities. The study linked pain severity and its impact to factors like gender, tooth brushing frequency, sweet consumption, and past experiences with baby tooth cavities.
Understanding these causes can help you figure out what might be going on and whether your child needs professional care. Here are the most common reasons children experience tooth pain:
Cavities and Tooth Decay
One of the most frequent causes. When bacteria from sugary foods and poor oral hygiene create acid that eats away at the tooth’s enamel, it can lead to painful cavities. If left untreated, the pain often worsens as the decay reaches deeper layers of the tooth.
Emerging or Loose Baby Teeth
As baby teeth grow in or start to fall out, they can cause temporary discomfort. The pressure of new teeth pushing through the gums or the wiggle of a loose tooth can make eating and brushing uncomfortable. Mild swelling and tenderness around the gums are normal, but if the pain becomes severe, bleeding lasts too long, or your child has trouble eating, it’s worth checking with a dentist.
Gum Infections
Poor brushing habits can lead to plaque buildup along the gumline, causing redness, swelling, and sometimes pain. In more serious cases, this can turn into a more advanced gum infection.
Tooth Sensitivity
Some children may experience sharp pain when eating hot, cold, or sweet foods. This can happen if their enamel is thin or worn down, exposing the sensitive inner part of the tooth.
Dental Injury
Kids are active, and accidents happen — a fall, bump, or hard hit during play can cause a tooth to become chipped, cracked, or even loosened, leading to pain. Sometimes, the injury isn’t immediately visible but still affects the tooth’s nerve.
Food Stuck Between Teeth
Something as simple as a stubborn popcorn kernel or piece of meat stuck between teeth can irritate the gums, creating discomfort that feels like a toothache.
Grinding Teeth (Bruxism)
Many children unknowingly grind their teeth, especially during sleep. This can wear down the enamel over time and cause tooth pain or jaw soreness.
Sinus Infections
In some cases, a toothache — especially in the upper back teeth — might not be about the teeth at all. A sinus infection can create pressure that feels like tooth pain, adding to the confusion.
While some causes of a child’s toothache are minor and can resolve on their own, others may require a dentist’s help to prevent further pain or complications. Keeping an eye on your child’s symptoms and knowing what to look for can make a big difference in how quickly you get them the relief they need.
Signs Your Child Might Have a Toothache
Recognizing a toothache in children isn’t always straightforward — especially if they’re too young to explain what’s wrong. Paying attention to their behavior and physical symptoms can help you identify when something isn’t right. Here are key signs to watch for:
Complaints of Tooth Pain
Children may directly say their tooth hurts, but younger kids who struggle to communicate might show their discomfort by crying, fussing, or repeatedly touching their mouth or jaw.
Sensitivity to Hot or Cold Foods
If your child reacts sharply to hot or cold foods and drinks — like pulling away, wincing, or refusing certain foods — it could be a sign of tooth sensitivity. This often stems from cavities, thinning enamel, or exposed tooth roots due to gum irritation.
Swollen or Red Gums
Inflammation around a tooth or along the gumline can signal an infection or irritation. Swollen gums may look red and tender, and they might bleed during brushing or eating.
Difficulty Chewing
If your child avoids chewing on one side of their mouth or refuses to eat certain foods, it could point to a cavity, cracked tooth, or food lodged between teeth causing pain when they bite down.
Trouble Sleeping Due to Pain
Toothaches often worsen at night due to increased blood flow to the head when lying down. A child experiencing a persistent toothache may struggle to sleep or wake up frequently in discomfort.
When to See the Dentist
Some toothaches resolve on their own, but others need professional care. Take your child to the dentist if you notice:
- Pain lasting more than 24 hours or getting worse.
- Swelling in the face or jaw — could indicate infection.
- Fever or general discomfort alongside tooth pain.
- Difficulty eating or drinking due to pain.
- Broken, cracked, or loose permanent teeth — even without pain.
When in doubt, it’s better to get it checked early to prevent bigger problems.
