“Why do cavities still happen if I brush every day?”
“Do I really need to use floss?”
“Can mouthwash be used instead of brushing?”
Even if you brush three times a day, if your oral care products are used incorrectly,
cavities, gum disease, and bad breath can easily develop.
Start with choosing the right toothbrush
A toothbrush is the foundation of oral care.
But a “good toothbrush” is not an expensive one,
it is one that suits the shape of your teeth and the condition of your gums.

✅ Soft-bristled toothbrush – Recommended for people with sensitive gums or tooth sensitivity
✅ Medium-bristle toothbrush – Suitable for most adults
✅ Small-head toothbrush – Allows detailed cleaning even in hard-to-reach areas
Replace your toothbrush every 3 months,
and if the bristles are frayed, replace it immediately.
Worn bristles are much more likely to allow bacterial growth
than to provide effective cleaning.
Do you really need floss and interdental brushes?
Many people think, “Brushing alone is enough,”
but toothbrush bristles do not fully reach
between the teeth.

If food debris and plaque remain in those gaps,
they can cause cavities, gum inflammation, and bad breath.
That is why floss and interdental brushes are needed.
How to use floss

1️⃣ Cut about 40 cm of floss and wrap it around both hands.
2️⃣ Slowly wrap it around the space between the teeth in a “C shape”
and move it up and down.
3️⃣ Gently insert it slightly below the gum line
and clean softly.
💡 Caution
If you force it in too hard, you may injure your gums,
so move slowly and minimize friction.
How to use an interdental brush

For people with wider spaces between teeth or orthodontic appliances,
an interdental brush is more efficient.
Gently scrub areas that floss cannot reach
to remove plaque.
✅ After use, rinse under running water and
let it dry completely.
✅ Using it once a day, before bedtime, is most effective.
Mouthwash is not a substitute for brushing
Many people ask, “When I’m too lazy to brush,
can I just use mouthwash?”
But mouthwash is an “auxiliary care product.”

After physical cleaning with a toothbrush and floss,
it plays the role of chemically suppressing remaining bacteria.
Precautions when choosing mouthwash
✅ Alcohol-free – Less irritating to the gums and
causes less dryness
✅ Products containing fluoride – Strengthen cavity prevention
✅ Contains antibacterial ingredients – Suppresses bad breath and plaque
💡 Tip
30 minutes after brushing, use mouthwash for at least 30 seconds and spit it out.
If you rinse with water, the active ingredients will be washed away immediately.
Keep using tongue cleaners and Waterpiks consistently
Tongue cleaner

A bacterial film builds up on the surface of the tongue and causes bad breath.
Use a soft tongue cleaner and sweep from back to front
in one direction.
However, too much pressure can
damage the taste buds.
Waterpik (oral irrigator)

This is a device that cleans between the gums and teeth
with a high-pressure stream of water.
It is especially useful for people who have difficulty using floss
or for implant and orthodontic patients.
However, a Waterpik does not replace brushing
and should be used as an auxiliary care tool.
Real care is completed by oral care products + regular checkups
No matter how good your oral care products are,
tartar and plaque harden over time
and become difficult to remove on your own.
Therefore, professional care through regular scaling and checkups every 6 months is essential.
