Why Milk Teeth Matter
Being temporary does not make milk teeth unimportant; they have four functions, each affecting the permanent dentition.
Reserving space for permanent teeth
This is the critical function: each milk tooth holds space for its successor. If lost early, neighbours drift into the gap and the permanent tooth becomes impacted or erupts crowded — hence space maintainers.
Chewing and nutrition
A child with painful or missing teeth cannot chew properly, avoiding firm and fibrous foods for soft, carbohydrate-rich ones — reducing nutritional quality and creating a vicious circle.
Speech development
The front milk teeth are involved in producing certain sounds correctly; early loss during the peak of speech development can lead to persistent difficulties.
Infection risk
Advanced decay can form an abscess that affects the developing permanent tooth bud beneath, leaving lifelong enamel defects — the most serious cost of neglect.
Preventive Dentistry for Children
The strength of paediatric dentistry lies in prevention rather than treatment.
Fissure sealants
The deep grooves on molar chewing surfaces cannot be reached by brush bristles. A sealant is a flowable material that smooths these grooves, applied painlessly without anaesthesia or tooth reduction, ideally soon after the molars erupt.
Fluoride application
Fluoride strengthens enamel against acid attack; professionally applied gel or varnish provides far greater protection than toothpaste, repeated according to the child's risk level.
Building good brushing habits
Brushing should start when the first tooth appears, done by the parent in young children — manual dexterity is usually insufficient until around age seven or eight.
Diet and sugar frequency
What matters most is the frequency of sugar, not the amount: each exposure raises acid levels and enamel stays vulnerable while saliva neutralises it. Grazing all day is far worse than the same amount at once, and bottles at bedtime cause rapid decay in the front teeth.
Preparing Your Child for the Dentist
The first experience shapes a lifelong relationship with dentistry, so the first visit should ideally happen at a calm time rather than in an emergency.
When should the first visit be?
When the first tooth appears, or by around age one. This visit usually involves no treatment, so the child does not associate the clinic with pain from the outset.
Words to avoid
Children fear uncertainty more than pain, and some well-meaning phrases increase anxiety.
- "Do not be afraid, it will not hurt" — introduces the idea of pain
- "They will not give you an injection" — introduces the concept
- "If you behave I will buy you a present" — turns it into a negotiation
- Sharing your own dental fears
- Using the dentist as a threat
What to say instead
Simple, neutral phrasing such as "they will count your teeth" is enough. Book the appointment when the child is rested, and bring a favourite toy.
Treatments Applied in Children
Like permanent teeth, primary teeth can be restored with fillings, crowns, pulp treatment and, where needed, space maintainers.
Fillings and crowns for primary teeth
Primary enamel and dentine are thinner, so decay progresses faster. Early lesions are restored with fillings in short appointments; where tissue loss is extensive, preformed crowns cover the whole tooth and maintain function and space until exfoliation.
Pulp treatment in primary teeth
When decay reaches the pulp, the tooth is not simply extracted: the coronal pulp may be removed and the radicular tissue medicated, or the canals cleaned and filled with a resorbable material so the root can resorb naturally as the permanent tooth erupts.
What space maintainers do
If a primary tooth is lost early, neighbouring teeth drift into the gap and the permanent successor may lack space. A fixed or removable space maintainer holds the gap until eruption and requires regular review as the jaw grows.
Habits, Mouth Breathing and Dental Alignment
Certain persistent habits and breathing patterns in childhood can influence jaw growth and dental alignment.
Thumb sucking, dummies and bottles
Sucking is normal in infancy and usually fades. If it continues while the front teeth are erupting, an open bite and narrowing of the upper arch may develop. The approach is gradual reduction rather than punishment; mild changes often self-correct after the habit stops.
Mouth breathing and its effect on dentition
A child who cannot breathe comfortably through the nose keeps the mouth open; with the tongue away from the palate, the upper jaw may not widen properly and crowding can follow. An ENT assessment is needed alongside dental evaluation.
Signs that warrant early orthodontic assessment
- No spacing at all between the primary teeth
- The lower jaw sitting ahead of the upper jaw
- Front teeth not meeting when biting
- A permanent tooth erupting behind the primary one
- The jaw shifting to one side on closing
- Losing a primary tooth much earlier than expected
- Thumb sucking that persists beyond four years of age
