Pediatric dental conditions
What's actually happening in your child's mouth — and what to do about it
Every condition in this library is described three times: once for a worried parent who Googled a symptom at 11pm, once for a dentist who wants the evidence base and treatment pathway, and once as a plain-language explanation your child can understand. That structure exists because pediatric dental conditions almost never sit in one bucket — early childhood caries has behavioural, dietary, microbial and craniofacial dimensions, and any advice that only addresses one is going to fail. We cover the everyday conditions most families encounter (cavities, gingivitis, tooth trauma, teething, malocclusion, tongue-tie) and the rarer ones that parents often carry alone (amelogenesis imperfecta, molar-incisor hypomineralisation, cleidocranial dysplasia, bruxism-related airway concerns).
Conditions link both to treatments and to symptoms, so you can enter the library from whichever direction matches how you're thinking. If your six-year-old's new molars came in with chalky yellow-brown patches, you probably don't yet know the diagnosis is MIH — you know your child screams when they brush that tooth. Starting from the symptom ("hypersensitive first permanent molar") gets you to the condition (molar-incisor hypomineralisation), which then gets you to the treatments (desensitising varnish, sealants, glass-ionomer restoration or a preformed metal crown depending on breakdown severity). Every entry is versioned and medically reviewed, and — where we can — includes short video from a specialist showing the clinical picture. The goal is fewer late diagnoses and fewer families told "there's nothing we can do" when there is.
The four things this pillar actually covers
Cavities and caries risk
Early childhood caries, occlusal decay, interproximal lesions, root caries in teens with orthodontic hygiene lapses — with the risk-assessment tools your dentist uses.
Gum, tissue and eruption issues
Gingivitis, geographic tongue, mucoceles, teething, eruption cysts, delayed and ectopic eruption — most benign, some worth a same-week visit.
Trauma and emergencies
Avulsions, luxations, crown fractures, soft-tissue lacerations — the first 30 minutes matter enormously, and every page includes the do's and don'ts.
Growth, airway and habits
Malocclusion, crossbite, open bite, thumb-sucking, mouth-breathing and sleep-disordered breathing — the airway-first pediatric lens that older textbooks skip.

Frequently asked
Answers to the questions parents ask us most
How do I tell a dental emergency from something that can wait?
Anything involving avulsed permanent teeth, uncontrolled bleeding, facial swelling that's spreading, difficulty swallowing or breathing, or trauma with loss of consciousness is a same-hour emergency. Toothache that's constant, waking your child at night, or unresponsive to over-the-counter pain relief is a same-day visit. Sensitivity to cold that resolves within seconds is usually a same-week appointment.
Is early childhood caries really caused by bottles at night?
Prolonged exposure to fermentable carbohydrates — including breastmilk, formula, juice and sweetened milk — is a major driver, but not the only one. Enamel defects, salivary composition, family bacterial transmission and diet timing all contribute. Blaming bottles alone misses at least half of high-risk kids.
My child's permanent teeth are coming in yellow. Is that normal?
Permanent teeth are naturally more yellow than primary teeth because their enamel is thinner over more yellow dentine. But localised chalky white, yellow or brown patches on new molars or incisors can indicate molar-incisor hypomineralisation, which needs early intervention to prevent breakdown.
Do baby teeth with cavities really need to be fixed if they'll fall out anyway?
Yes. Primary molars typically don't exfoliate until age 10–12. An untreated cavity that reaches the pulp causes pain, infection, missed school and can damage the developing permanent tooth underneath. Early extraction without a space maintainer often causes crowding that becomes an orthodontic case later.
When should I worry about my child's bite or jaw?
Ask your pediatric dentist for an orthodontic screening at age 7, per AAO guidelines. Anterior or posterior crossbites, severe crowding, open bite from prolonged habits, or a family history of skeletal Class III should trigger a Phase-I orthodontic consultation even earlier.
