The recommendation is the first birthday, or six months after the first tooth appears — and that first appointment is mostly a conversation with the parent.
Paediatric dental associations in Europe and North America converge on the same advice: a first visit by the first birthday, or within six months of the first tooth appearing. At that age the point is not treatment. It is catching night-bottle decay before it becomes visible, checking the tongue and lip attachments, and agreeing how much fluoride toothpaste to use — a smear the size of a grain of rice under three, a pea after that.
The child sits on the parent's lap facing them and tips back into the dentist's lap, which takes about two minutes and involves no instruments beyond a mirror and a light. There is no drilling and usually no radiograph. The entire aim is to make the dental chair boring long before it ever has to be interesting, and to establish six-monthly fluoride varnish and sealants on the first permanent molars around six or seven.
The back baby teeth stay in the mouth until ten to twelve years old. An abscess on one of them sits directly above the developing permanent tooth and can damage its enamel permanently. Losing a baby molar early lets the neighbouring teeth drift into the gap, which produces crowding a decade later that then needs orthodontics. They will fall out anyway is the most expensive sentence in paediatric dentistry.
Do not fly a child to Istanbul for a check-up. That relationship belongs with a paediatric dentist within driving distance of your home, who will see them every six months and know them by name. We treat children who are already here with a parent under treatment, and we deliberately do not offer general anaesthetic paediatric packages, because that kind of care needs follow-up we cannot give from another country.
Most small fillings in cooperative children over four are done with local anaesthetic and a calm, unhurried approach. Sedation is a tool for genuine inability to cooperate or for extensive treatment, not a way of getting through a long appointment faster.
A single digital bitewing delivers a very small dose, comparable to a short period of ordinary background radiation, and we use them only when a decision depends on the image. Between the back teeth is precisely where decay hides from the eye.
