5 Reasons Why Your Child’s Teeth May Hurt And What to Do About It
Tooth pain in children is a common yet distressing issue for parents. While it may be tempting to wait and see if the pain subsides on its own, doing so could delay treatment for a potentially serious dental condition.
At Little Diamonds Pediatric Dentistry, our board-certified pediatric dentists work closely with families to help children maintain optimal oral health. Based on clinical experience and the most current pediatric dental guidelines, this article explores 5 reasons your child’s teeth may hurt—and what you can do to help.
1. Tooth Decay (Dental Caries)
Tooth decay, also known as dental caries, is the most prevalent chronic disease among children in the U.S., according to the Centers for Disease Control and Prevention (CDC). Decay occurs when cavity-causing bacteria feed on sugars from food and beverages, producing acids that damage tooth enamel.
Common Signs:
- Pain or sensitivity when eating or drinking
- Visible holes, pits, or dark spots on the teeth
- Discomfort while chewing
Why It Matters:
Untreated cavities can lead to infection, abscesses, and even early tooth loss, which may impact speech, nutrition, and permanent tooth development.
Expert Tip:
Visit a pediatric dentist if you notice any of these symptoms. Early detection allows for minimally invasive treatments such as fluoride applications or small fillings.
2. Teething (In Infants and Toddlers)
For infants and toddlers, tooth pain often results from teething—a natural but sometimes uncomfortable process as primary teeth break through the gums. This typically begins around 6 months of age.
Symptoms May Include:
- Drooling
- Chewing on objects or fingers
- Swollen or red gums
- Irritability or disrupted sleep
What Pediatric Dentists Recommend:
Use a chilled (not frozen) teething ring and gently massage your child’s gums. Consult your pediatric dentist before using any over-the-counter medications.
Note:
Fever and diarrhea are not typical symptoms of teething. If these occur, contact your child’s physician.
3. Dental Trauma or Tooth Injury
Children are naturally active, making them prone to falls and accidents that may result in dental trauma. Even if there’s no visible damage, internal injuries to the tooth or surrounding structures can cause significant pain.
Red Flags Include:
- Persistent pain after a fall
- Chipped or cracked tooth
- Loose or displaced tooth
- Bleeding around the gums or lips
Clinical Insight:
Timely evaluation by a pediatric dentist can prevent complications and increase the chance of saving an injured tooth. In many cases, dental X-rays are needed to assess internal damage.
4. Eruption Pain from New Teeth
Tooth eruption doesn’t end with teething. As your child’s permanent teeth begin to emerge (typically around age 6), they may experience temporary discomfort or pressure in the jaw or gum line.
What to Watch For:
- Tender gums near erupting molars
- Irritation at the back of the mouth
- Mild pain without signs of decay or infection
Parental Guidance:
Eruption-related pain is usually short-lived. Cold compresses, soft foods, and salt water rinses can offer relief. If pain is persistent or severe, have your child evaluated to rule out impaction or infection.
5. Gum Inflammation or Early Gum Disease
Poor brushing habits or plaque buildup can lead to gingivitis, a mild and reversible form of gum disease. This condition can cause gum sensitivity, bleeding, and even tooth discomfort—especially during brushing or eating.
Warning Signs:
- Red, swollen, or bleeding gums
- Chronic bad breath
- Gum pain while brushing
- Receding gum lines
How to Prevent It:
Teach your child proper brushing and flossing techniques early. Use a soft-bristled toothbrush and supervise until they can brush effectively on their own (usually around age 7–8). Pediatric dental cleanings every six months are also crucial.
When Should You Call a Pediatric Dentist?
While some causes of tooth pain may be minor or temporary, others require urgent care. Seek professional help if your child has:
- Pain lasting more than 48 hours
- Facial swelling or fever
- An injured or knocked-out tooth
- Signs of infection, such as pus or abscesses
- Difficulty eating, sleeping, or focusing due to discomfort
At Little Diamonds Pediatric Dentistry, we provide gentle, child-centered care tailored to each developmental stage. Our team uses age-appropriate techniques and advanced diagnostic tools to get to the root of the problem quickly and safely.
How to Help Your Child Avoid Toothaches
Preventive care plays a key role in keeping your child’s smile pain-free. Here are evidence-based practices recommended by the American Academy of Pediatric Dentistry (AAPD):
- Brush twice daily with fluoride toothpaste
- Floss once a day (especially between molars)
- Limit sugary foods and drinks
- Visit the dentist every six months
- Use a sports mouthguard for physical activities
Good oral hygiene habits and regular checkups can reduce the risk of many common causes of dental pain in children.
Final Thoughts: Protecting Your Child’s Dental Health

FAQs
Is it normal for a child to have occasional tooth pain?
Mild, short-term tooth discomfort can be normal—especially during teething or when new permanent teeth are erupting. However, if your child’s toothache persists longer than 48 hours, is severe, or is accompanied by swelling, fever, or visible damage, it’s important to see a pediatric dentist. Persistent pain can indicate conditions such as tooth decay, gum inflammation, or trauma that require professional attention.
Can a child get a cavity even if they brush daily?
Yes. While regular brushing is essential, cavities can still develop due to factors such as poor brushing technique, skipping flossing, frequent snacking on sugary foods, or not using fluoride toothpaste. Children may also be genetically predisposed to dental decay. That’s why dental checkups every six months and professional cleanings are essential—even if your child brushes and flosses daily.
How can I tell if my child’s tooth pain is from teething or something more serious?
Teething typically causes mild discomfort, drooling, gum swelling, and irritability in infants and toddlers. It does not usually cause fever, rashes, or intense pain. If your child has persistent pain, visible tooth damage, bleeding gums, pus, or systemic symptoms like fever, the issue may be more serious—such as an infection or dental trauma—and warrants a dental evaluation.
What should I do if my child knocks out a tooth?
If a baby tooth is knocked out, do not attempt to reinsert it. Contact your pediatric dentist to determine the next steps. If a permanent tooth is lost, gently rinse it with saline or milk—avoid touching the root—and try to place it back in the socket. If that’s not possible, store the tooth in milk or saline and seek emergency dental care immediately.
Can a poor diet contribute to tooth pain in kids?
Yes. A diet high in sugary snacks, sticky candies, and acidic beverages (like soda and fruit juice) can significantly increase the risk of enamel erosion and cavities—both of which can lead to tooth pain. Balanced nutrition with limited sugar intake supports overall oral and systemic health.
When should my child first visit a pediatric dentist?
The AAPD recommends that children see a pediatric dentist by their first birthday or within six months of the first tooth erupting—whichever comes first. Early dental visits establish a dental home and help detect any emerging issues before they become more serious.
How can I relieve my child’s tooth pain at home until we visit the dentist?
Temporary relief may be provided using:
- A cold compress on the outside of the cheek
- Over-the-counter pain relievers (consult your pediatrician first)
- Soft foods and lukewarm liquids
- Gentle brushing with a soft-bristled toothbrush
What are signs of dental infection in children?
Signs of a dental infection (abscess) may include:
- Severe, throbbing tooth pain
- Swelling in the face or jaw
- Pus discharge from the gumline
- Fever
- Swollen lymph nodes
Is it better to see a pediatric dentist over a general dentist for my child’s toothache?
Yes. Pediatric dentists receive 2–3 years of additional training beyond dental school, focusing specifically on child psychology, development, sedation options, and behavior management. They are equipped to treat infants, toddlers, children, and teens using child-friendly techniques and tools.
