The first visits matter more than the treatment
A child's early appointments set whether the dentist is a normal part of life or something to dread for the next forty years. That is worth more clinically than anything done on the day, so those appointments are not rushed.
Most of the work is preventive: fissure sealants over the grooves in new adult molars, fluoride where the risk of decay is high, and showing a parent what is actually happening in their child's mouth.
Growth, space and habits
Baby teeth hold space for the adult teeth behind them. When one is lost early, a space maintainer keeps that gap open — otherwise the neighbours drift into it and an orthodontic problem is created that did not need to exist.
Thumb-sucking and tongue-thrusting past a certain age change how the jaw develops. Habit-breaking appliances deal with that while it is still easy to deal with.
Pediatric care under general anaesthesia
Some children cannot have treatment in the dental chair: an emergency that cannot wait, a child who is not able to cooperate however gently it is approached, or a child with special needs for whom a normal appointment is not workable.
For them, treatment can be carried out under general anaesthesia. This is not done at the practice itself: it is arranged in collaboration with a hospital, where the anaesthetic is given, and the dental work is planned by the practice beforehand.
