Kids do not always come right out and say a tooth hurts. More often, the signs show up sideways: a sudden pickiness about food temperature, a puffy cheek, breath that smells different than usual. The most common signs your child may have a dental problem are tooth pain or sensitivity, white or brown spots on the teeth, swollen or bleeding gums, breath that will not clear up with brushing, and a sudden reluctance to chew on one side of the mouth. Catching these signals early, and knowing when a symptom needs a same-week visit versus a same-day one, can spare your child a lot of unnecessary discomfort.
At Crescent Kids Dentistry, we see this play out with families across Griffin every week. Parents often mention that something felt slightly “off” for weeks before they realized a cavity or an infection was forming underneath a tooth. Our whole approach is built around treating patients from their very first tooth through their late teenage years in a space designed to feel more welcoming than clinical, so parents are comfortable staying close and children are comfortable speaking up when something hurts. This guide walks through the specific signs to watch for, what tooth pain tends to look like at different ages, and how to tell when a dental concern can wait for a routine visit versus when it needs a phone call today.

How Do I Know If My Child Has a Cavity?
The clearest signs of a cavity are a spot of discoloration on a tooth (white, brown, or black), a small pit or hole on the tooth’s surface, and complaints of sensitivity when eating something cold, hot, or sweet. Not every cavity announces itself this clearly. Some of the earliest stages of tooth decay have no visible signs at all, which is one of the biggest reasons routine checkups matter more than waiting for a complaint to show up.
Tooth decay usually starts small. A dull white spot near the gumline means the enamel is beginning to lose minerals, and at this stage it can often be reversed with fluoride and better brushing habits. Left alone, that spot darkens to brown or black, and eventually a visible pit or hole forms. Because young children cannot always describe what they are feeling, many cavities are only found during a scheduled exam rather than because a child complained about pain.
Common signs of a cavity to watch for include the following.
- A white, brown, or dark spot on a tooth that was not there before
- A visible pit or small hole, especially on a back molar
- Sensitivity to cold, hot, or sweet foods and drinks
- A tooth that looks slightly discolored compared with the others nearby
- Bad breath that lingers even right after brushing
Our team checks for every one of these signs at each preventive visit, using a gentle exam alongside the modern technology in our office to catch decay long before it turns into a bigger problem. Regular cleanings and fluoride treatments are also one of the simplest ways to keep small spots from becoming cavities that need a filling at all. When a filling is needed, we use tooth-colored fillings so the repair blends in naturally and your child does not walk away with a mouth full of metal.
What Are Signs of Tooth Pain in Kids?
Tooth pain in kids usually shows up as trouble chewing, sudden pickiness about food temperature, or crankiness that does not have another obvious cause. Younger children who do not yet have the words to say a tooth hurts often show it through behavior instead, like tugging at a cheek, refusing to eat on one side of the mouth, or waking up crying in the middle of the night.
What this looks like tends to shift as kids get older. A toddler might just seem fussier than usual around mealtime. A school-age child might tell you a specific tooth hurts, or wince when they drink something cold. A teenager might describe a dull ache that comes and goes with pressure, or notice a tooth that suddenly feels loose or different.
Signs of tooth pain to watch for by age typically include the following.
- Infants and toddlers: fussiness during meals, extra drooling, refusing a bottle or solid foods, chewing only on one side
- School-age children: complaints about a specific tooth, wincing at cold drinks, avoiding crunchy snacks they normally enjoy
- Preteens and teens: pain that comes and goes with pressure or temperature, a tooth that feels loose or off, soreness on one side of the jaw
Pain that lingers for more than a day or two, or pain paired with swelling, usually means there is an infection brewing under the surface rather than simple sensitivity. That combination is worth a same-day call rather than waiting to see if it passes on its own. We would always rather see a child for a quick exam and find nothing serious than have a parent sit at home wondering.
When Should I Take My Child to the Dentist?
Schedule a visit as soon as you notice a new spot on a tooth, ongoing sensitivity, or pain that lasts more than a day or two. If your child has facial swelling, a fever alongside tooth pain, or an injury that knocks a tooth loose or out, that counts as a dental emergency and calls for same-day care rather than waiting for the next routine cleaning.
Outside of emergencies, checkups every six months remain the best way to catch problems while they are still small and easy to treat. During a routine visit, our team can spot early decay, tighten up a home brushing routine, and apply preventive treatments like sealants before a tiny issue turns into a filling. For anything more urgent, our office is equipped to handle common childhood dental emergencies, and options like nitrous oxide help keep kids calm and comfortable during treatment.
Contact our office right away if your child has any of the following.
- A knocked-out or badly chipped tooth
- Facial or gum swelling, with or without a fever
- Pain severe enough to interfere with eating, sleeping, or school
- Bleeding from the mouth that does not stop after a few minutes
If you are ever unsure whether something is urgent, it is always fine to call and describe what you are seeing. Our team would rather take a quick look and rule something out than have a parent wait and worry.
