How to Keep Your Teeth Beautifully White – Regular Maintenance is Key
Medical whitening (in-office bleaching) is a safe and professional treatment that restores the natural whiteness of your teeth — available only at dental clinics.
However, the effects are not permanent.
In everyday life, teeth naturally become stained over time. To maintain a white and bright smile, regular maintenance is essential.
How to Maintain the Brightness
Keep Your Brightest Smile All the Time
Visit the clinic approximately once a month to maintain the best possible shade of white.
Cost-Effective Whitening Maintenance
Combine with routine cleanings for oral health and return every 3–4 months for touch-up whitening.
Additional Notes
・Treatment Frequency Limits
To avoid stress on your teeth and gums:
– Please wait at least one week between whitening sessions.
– Limit to no more than 3–4 visits per month.
・If You Feel Occasional Sharp Pain After Treatment…
Some people may feel a slight or sharp pain during or after treatment.
This can occur especially when there are small pre-existing cracks or damage to the teeth.
This pain is often caused by:
“Temporary dehydration of the teeth”
It may feel similar to sensitivity but does not mean your teeth are damaged.
This sensation typically disappears within a few hours to a few days, as saliva naturally restores moisture to the enamel.
If the pain becomes unbearable or persists for several days, please contact us — the cause may be unrelated to whitening.
We also offer pain-less (low-sensitivity) whitening options.
If you’re interested, feel free to ask us.
