The clinical centrepiece is early childhood caries — any caries experience in a child of seventy-one months or younger — with its pathognomonic pattern of upper incisors and first molars destroyed while the lower incisors, bathed in tongue-protected saliva, stand untouched; its drivers are nocturnal bottle- and breastfeeding-on-demand, sweetened fluids and transmission of mutans streptococci from mother to infant. Around that core sit the practical numbers — rice-grain and pea-sized amounts of 1000 ppm fluoride toothpaste, the thirty-day definition of neonatal teeth, and the teething management that explicitly excludes numbing gels. ## What you must remember - The age-one visit: the first examination within six months of the first tooth erupting and by twelve months, comprising caries risk assessment, knee-to-knee examination, anticipatory guidance and fluoride varnish where risk warrants. - Early childhood caries definition (per paediatric dentistry guidance): one or more decayed, missing or filled primary tooth surfaces in any child aged seventy-one months or younger — with upper incisors and first molars destroyed first by pooled nocturnal feeding while tongue-protected, saliva-bathed lower incisors are spared longest, a distribution the examination tests as a photograph. - Mutans streptococci pass vertically, chiefly from the caregiver; colonisation earliest in the second and third years (Caufield's window of infectivity), and delayed colonisation means less caries — maternal oral health and treating active caries in pregnancy matter. - Fluoride toothpaste amounts: a rice-grain smear of at least 1000 ppm paste under three years, a pea-sized amount from three to six, brushing twice daily with an adult supervising — children lack the dexterity to brush alone until roughly eight to ten years. - Weaning milestones: no bottle in bed, weaning by about twelve months, open cup from six months, juice restricted in favour of water and milk. - Teething: chilled teethers, massage and analgesics as needed; fever and diarrhoea are not teething signs, and benzocaine and viscous lidocaine gels are avoided for methaemoglobinaemia risk. - Natal teeth are present at birth, neonatal teeth erupt within the first thirty days (incidence roughly one in a thousand to three thousand); they are usually the normal primary incisors and are extracted only if mobile and endangering the airway or causing Riga-Fede ulceration of the ventral tongue. - Avulsed primary teeth are never replanted — a first-aid instruction given to every caregiver of a toddling child. ## Conducting the twelve-month visit A one-year-old attends with her mother, who asks whether teeth "this early" really need a dentist. The visit is conducted knee-to-knee: infant across both laps, head on the dentist's knees, and the examination of teeth, gingivae, frenum and soft tissues completed in minutes with mirror and light. Risk assessment — night breastfeeding on demand, honey use, no toothpaste yet, active maternal caries — scores this child high risk. Anticipatory guidance for the next six months: rice-grain 1000 ppm paste twice daily, no bottle in bed, cup practice, sweet fluids decoupled from sleep, and the mother's own restorative care as transmission control. Fluoride varnish is applied to the four incisors. Recall is set at three months, and the mother leaves with two specific behaviours rather than a lecture — the infant visit succeeds by being narrow, concrete and repeatable. ## Where students slip The numbers trip candidates first: rice-grain versus pea-sized paste amounts with their age bands, the seventy-one-month ECC definition, and the thirty-day natal-neonatal boundary are the three figures examiners reach for. The teething myths are the second trap — endorsing fever or diarrhoea delays diagnosis of real illness; correct management is chilled teethers, massage and analgesia. The third is replanting avulsed primary teeth: never, because of the ankylosis and successor-damage risk — an answer that must come unqualified. Finally, lower-incisor sparing in ECC is not luck but anatomy and saliva, and explaining it earns the mechanism mark. ## Frequently asked questions ### When should the first dental visit occur? Within six months of the first tooth and by the first birthday — early enough to prevent rather than treat. ### How is early childhood caries defined? One or more decayed, missing or filled primary surfaces in a child seventy-one months or younger, classically involving maxillary incisors and molars. ### How much fluoride toothpaste should a child use? A rice-grain smear of at least 1000 ppm paste under three, a pea-sized amount from three to six, twice daily supervised. ### What are natal and neonatal teeth? Natal teeth present at birth, neonatal within thirty days; most are true primary incisors, extracted only if dangerously mobile or causing Riga-Fede ulceration. ### How is teething managed? Chilled teethers, gum massage and weight-appropriate analgesia; fever and diarrhoea warrant medical review, and numbing gels are avoided. ### Why are avulsed primary teeth never replanted? Replantation risks ankylosis, infection and damage to the developing successor.
