A child’s smile tells a story—one of curiosity, growth, and endless discovery. But when discomfort appears in the form of a toothache, that story can take an unexpected turn.
Toothaches in kids aren’t just about the pain. They’re a sign, a cue that something deeper is happening beneath the surface. Whether it’s a new tooth making its debut, a little too much sugar sneaking into snack time, or an unexpected dental injury, knowing what causes toothaches (and how to prevent them) is the key to keeping those little smiles healthy and happy.
As we honor National Children's Dental Health Month, let's explore how to keep those precious smiles bright and pain-free.
What’s Causing Their Toothache?
Cavities: The Sneaky Culprit
Cavities form when bacteria break down food particles and create acid, which slowly wears away enamel. If left untreated, cavities can reach the nerve, leading to sensitivity, pain, and discomfort.
Signs to Watch For
-
Complaints of pain when eating something sweet, hot, or cold
-
Visible white spots, brown patches, or tiny holes in teeth
-
Sensitivity when brushing
How to Prevent It
-
Brush twice a day with a fluoride-based toothpaste to strengthen enamel
-
Limit sugary snacks and sticky treats that cling to teeth
-
Schedule regular dental checkups to catch early signs of decay
Teething & Growing Pains
As baby teeth erupt (or later, as adult teeth push through), inflammation in the gums can cause soreness and mild discomfort.
Signs to Watch For
-
Excessive drooling
-
A tendency to chew on hands, toys, or household objects
-
Mild irritability or disrupted sleep
How to Help
-
Offer a chilled (not frozen) teething ring for gum relief
-
Use a clean finger to gently massage sore areas
-
Advocate brushing with a soft-bristled toothbrush to keep gums clean
Dental Injuries: A Hidden Source of Pain
Accidents happen—whether it’s a fall at the playground or a bump during sports, teeth can sustain tiny cracks or bruises that may not be visible but can cause discomfort.
Signs to Watch For
-
Complaints of pain when chewing
-
A tooth that appears slightly darker than the others
-
Increased sensitivity to hot or cold
What to Do
-
If pain is minor, monitor the tooth and encourage soft foods
-
If pain persists, consult a dentist to check for hidden fractures
-
If a tooth is loose or knocked out, seek immediate dental care
Sensitivity & Grinding (Bruxism)
Some children unknowingly clench or grind their teeth, especially at night. Over time, this can wear down enamel and cause sensitivity.
Signs to Watch For
-
Complaints of a sore jaw in the morning
-
A noticeable grinding sound at night
-
Teeth that look flattened or chipped
How to Help
-
Encourage calming bedtime routines (think: a warm bath, a favorite book)
-
Schedule a dental visit if grinding persists—some children may need a night guard
When to Seek Wisdom
While we advocate for turning the necessary into the extraordinary, some moments require professional guidance. Trust your instincts when:
-
Pain persists beyond a gentle reminder, more than 24 hours
-
Swelling appears uninvited in the gums or face
-
Fever joins the conversation
-
There’s visible damage, such as a cracked or chipped tooth
Early intervention can prevent small issues from becoming big problems—which is why regular checkups are key.
A Note on Prevention
Prevention isn't merely about avoiding discomfort – it's about crafting routines that make care feel natural. Think of it as laying the foundation for a lifetime of healthy smiles:
Build a Daily Ritual
-
Brush twice daily for two full minutes with a soft-bristled toothbrush
-
Use fluoride toothpaste to strengthen enamel and fight cavities
-
Make brushing a fun, mindful moment—play a favorite song or set a timer
-
Allow routines to evolve as your child grows
Feed Their Smile
-
Swap sticky, sugary snacks for fresh fruits, crunchy veggies, and cheese (which helps neutralize acid!)
-
Encourage water over juice to rinse away food particles and bacteria
-
Avoid grazing—frequent snacking gives bacteria more time to produce acid
Make Dental Visits a Seasonal Routine
-
Think of dental visits like changing seasons—every six months is a good rule of thumb to catch potential issues early
-
Use these visits as a learning experience, reinforcing the importance of care
-
Let your child pick out a new toothbrush every three months—this keeps brushing fresh and exciting
Turning Small Moments into Lasting Smiles
In transforming oral care from obligation to ritual, we teach our children that self-care deserves time and attention. These quiet moments at the sink become opportunities for connection, for teaching, for growing.
Every brush stroke is an investment in their future smile, every gentle reminder a lesson in self-care, every morning and evening an opportunity to make the mundane magical.
This February, in honor of National Children's Dental Health Month, we’re partnering with America’s ToothFairy to bring healthier smiles to kids across the country. For every toothbrush purchased this month, we’ll donate a children’s toothbrush to a child in need.
Together, we can create brighter smiles—one brush at a time.
