The start of cavity prevention:

Fluoride application

Fluoride application is a preventive treatment that applies fluoride to the tooth surface

to protect teeth from cavities and

strengthen enamel.

Here, fluoride inhibits the demineralization process of teeth and

promotes remineralization,

playing a role in lowering the likelihood of cavities.

In particular, it increases resistance to acids produced by bacteria

and helps make teeth stronger again.

✅ Functions of fluoride

  • Inhibits tooth demineralization

  • Promotes remineralization

  • Increases acid resistance

✋Question✋

Is fluoride application really necessary?

Compared with adults, children have weaker teeth

and do not yet have a perfect brushing habit,

so they are at higher risk of developing cavities.

Fluoride application is a good starting point for preventive care

that helps reduce this risk.

Baby fluoride application timing

It can be done once the primary teeth start erupting,

but it is generally recommended at around age 2, when most of the primary dentition has come in.

Because this can vary depending on the child’s oral condition,

we recommend consulting a dentist about the right starting time

along with an examination.

After that, it is good to continue regularly until the permanent teeth erupt and grow.

Newly erupted teeth are not yet fully hardened,

and because this is the point when they begin to be exposed to the external environment,

it is a good time for early preventive care.

✋Question✋

Is fluoride safe?

The fluoride used in dental clinics

is performed by professionals in a professional setting,

with age-appropriate safe concentrations and doses considered for each individual,

so the possibility of harm to the human body is very low.

✋Question✋

Can adults also get fluoride application?

Adults need it too.

It is especially recommended for sensitivity, early cavities,

or when undergoing prosthetic treatment,

for preventive benefits.

Frequency of fluoride application

In general, fluoride application is recommended at intervals of 3 to 6 months.

This can vary depending on the condition of the teeth and mouth,

but if it is done together with the routine 6-month dental checkup,

the protective effect of fluoride can be maintained consistently,

making it even more effective for cavity prevention.

Children who are prone to cavities or consume a lot of sugar

may need care at shorter intervals.

For children at high risk of cavities,

fluoride application alone is not enough;

diet improvement and brushing education must be done together,

and it is best to set a customized schedule

through consultation with a dental specialist.

Fluoride application process

Fluoride application is a relatively simple

preventive treatment that takes a short amount of time.

Because there is no anesthesia or pain,

even children can receive it without much 부담.

① Check the tooth condition and perform an oral examination

Check the condition of the teeth and whether cavities are present,

and determine the timing and necessity of fluoride application.

② Clean and dry the teeth

To help the fluoride absorb well,

clean and dry the tooth surface.

*Scaling may be performed if needed

③ Fluoride application

Apply fluoride in gel or varnish form evenly to the tooth surface

and leave it in place for 1 to 2 minutes so it can work sufficiently on the teeth.

④ Aftercare

Avoid eating for at least 30 minutes to 1 hour,

and limit irritating foods on the same day.

✋Question✋

How long does the effect of fluoride application last?

It varies depending on the individual’s oral condition,

but the duration of the effect of fluoride application gradually decreases

as you carry out everyday activities such as eating and brushing,

and it is generally maintained for about 3 to 6 months.

Therefore, doing fluoride application consistently every 3 to 6 months

helps prevent cavities.

Precautions after the procedure:

Meals after fluoride application

Meals and precautions after fluoride application are as follows.

✅ Meals after fluoride application

After fluoride application, it is best to avoid food and drink,

including water, for at least 30 minutes to 1 hour.

After that, you may eat normally,

but it is best to avoid hard or sticky foods on the same day,

as well as irritating or acidic foods.

✅ Brushing after fluoride application

To allow the fluoride to be absorbed sufficiently,

it is recommended not to brush immediately after the procedure,

and on the evening of the same day, it is better to brush gently without scrubbing hard.

You can brush as usual starting the next day.

For children’s dental health, fluoride application

is one of the most basic and effective preventive treatments.

It can be started after the primary teeth erupt,

and it is best to maintain it at 3- to 6-month intervals.

Above all, because it is a treatment with proven safety,

performing it regularly

can greatly help your child’s long-term dental health.

There is also sealant,

another cavity-prevention treatment.

Sealant is also covered by insurance, so
