Why children’s dental visits matter

Starting dental visits early helps children stay cavity-free and grow up comfortable with the dentist. Regular check-ups let us watch how the baby and adult teeth are developing, catch small problems before they cause pain, and give parents practical advice on brushing, diet and habits such as thumb-sucking.

What we offer for children

  • Check-ups and cleaning: gentle examinations and a clean, with plenty of encouragement.
  • Prevention: fissure sealants (protective coatings on the biting surfaces) and fluoride to reduce the risk of decay.
  • Fillings and simple treatment: tooth-coloured, mercury-free restorations when needed.
  • Guidance: advice on brushing, diet and habits, and monitoring how the teeth and jaws are developing.

Helping your child feel at ease

A calm, unhurried, friendly approach helps children feel safe. We explain things in simple words, take our time, and build up trust visit by visit. For nervous children, gentle options can be discussed — see dentistry under sedation.

When should my child first see a dentist?

As a general guide, it is good for children to see a dentist while they are young — early visits are mostly about getting familiar and checking that development is on track. Bringing your child along to your own check-ups can also help them get used to the clinic.

Your child’s teeth, age by age: answers for parents

Short answers to the questions our dentists hear from parents across our five Hong Kong clinics, arranged by age with an illustration for each.

Toddlers (0–3): first teeth and first brushing

Child-sized soft toothbrush used once the first tooth appears

How soon should a baby’s teeth be brushed?

From the day the first tooth appears. A small, soft-bristled toothbrush made for children is enough; brush gently over the front, back and chewing surfaces.

Toothpaste amounts for young children: a rice-grain smear, then a pea-sized amount

How much fluoride toothpaste does a young child need?

A smear the size of a grain of rice from age 1 to 3, rising to a pea-sized amount from 3 to 6. Fluoride toothpaste is recommended for young children because it helps prevent decay; encourage them to spit out what’s left.

Spaces between baby teeth leave room for bigger adult teeth

Should I worry about spaces between my toddler’s teeth?

Usually not. Spacing between baby teeth is normal and a good sign: adult teeth are bigger, and those spaces give them room to come in.

Pre-school (3–6): habits, snacks and space

Long-term dummy use and how it can push the front teeth forward

At what age should thumb-sucking or dummy use stop?

Many children give these habits up by themselves somewhere between 2 and 4. If they continue beyond age 4, they can influence how the jaw grows and how the teeth line up, for example upper front teeth that push forward, so aim to wean your child off before then.

Gummies, bacteria and acid leading to tooth decay

Do gummy vitamins and fruit juice harm children’s teeth?

They can. Sticky, sugary foods and drinks stay on the teeth, giving bacteria time to turn the sugar into acid, and that acid makes decay much more likely.

A baby tooth keeping space for the adult tooth that follows

If baby teeth are replaced anyway, why look after them?

Children need them for chewing and clear speech, and each one keeps a space open for the adult tooth that follows. If one is lost too soon, the adult teeth may come in crowded or out of line.

School age (6+): adult teeth and bite checks

Back tooth grooves before and after sealing

Does my child need fissure sealants?

Sealants are a thin protective layer painted into the deep grooves on the chewing surfaces of back teeth, so food can’t lodge there and start decay. Dentists usually suggest them once the first permanent molars erupt, at about 6 years old.

Double row of teeth, known as shark teeth

Why is an adult tooth growing in behind a baby tooth?

This double row, often nicknamed “shark teeth”, happens quite often. In most cases the adult tooth shifts into position on its own. If the baby tooth stays put, have a dentist check whether it should be taken out.

Calendar and check-up marking the first orthodontic assessment by age 7

When should my child have a first orthodontic assessment?

Around age 7 is the guideline from the American Association of Orthodontists. By then a dentist can see how the jaws are developing and spot any bite issues while they are still easy to monitor.

Frequently asked questions

When should my child first see a dentist?
It is good for children to start dental visits young. Early visits are mainly about getting familiar with the clinic and checking that the teeth and jaws are developing well.
How often should children have a check-up?
About every six months for most children, or as your dentist advises based on their risk of decay.
What are fissure sealants?
Fissure sealants are thin protective coatings applied to the biting surfaces of the back teeth to help prevent decay in the grooves that are hard to clean.
Are children’s fillings safe?
Yes. We use tooth-coloured, mercury-free materials for children’s fillings.
My child is nervous — can you help?
Yes. A gentle, unhurried approach helps most children, and for those who are very anxious, options such as inhalation sedation can be discussed.
Should I bring my child to my own appointments?
It can help. Coming along to your check-ups lets your child get used to the clinic in a relaxed way before their own visit.
