IN-OFFICE TEETH WHITENING
One-Day Teeth Whitening
After checking your current tooth shade and the cause of discoloration,
we protect your gums and help brighten your teeth naturally.
What is one-day teeth whitening?
This is professional whitening performed at the dental office: after protecting your gums, professional whitening gel is
applied to the teeth to help brighten them
in a relatively short time.
Before treatment, we check your tooth shade and oral condition
and set up an individual whitening plan.
One-Day Teeth Whitening Who It Is For
If yellowed teeth or staining from lifestyle habits
is a concern,
one-day teeth whitening may be an option
after we check the condition of your teeth and gums.
Discoloration from
everyday habits over time
Nicotine stains from smoking
Discoloration from inadequate oral care
Teeth that are
naturally yellowish
A brighter smile
after orthodontic treatment
An upcoming wedding, job interview or similar event
One-Day Teeth Whitening Procedure
We check your oral condition and current tooth shade before whitening,
then proceed step by step from gum protection
to gel application and finishing.
STEP 01.
Oral Examination
We check for cavities, gum condition, sensitivity and existing restorations
to determine whether whitening is suitable for you.
STEP 02.
Tooth Cleaning and Shade Check
Debris and surface stains are cleaned from the teeth,
and your pre-treatment shade is recorded with a shade guide.
STEP 03.
Gum Protector Application
A protective barrier is carefully applied so the whitening gel
does not come into direct contact with the gums and soft tissue.
STEP 04.
Professional Whitening Gel Application
Professional whitening gel is applied evenly to the tooth surface,
and whitening proceeds while we monitor your comfort.
STEP 05.
Finishing and Shade Check
The gel is removed and the tooth surface is cleaned,
then the shade is compared before and after the procedure.

One-Day Teeth Whitening Aftercare Instructions
We check your oral condition and current tooth shade before whitening,
then proceed step by step from gum protection
to gel application and finishing.
Avoid irritating foods.
Spicy, hot or hard foods can temporarily irritate the gums,
so it is best to avoid them for 1 to 2 days.
Do not smoke for at least
3 to 5 days.
Smoking can cause new staining and slow recovery.
Brush gently,
without irritating the area.
Take care not to scrub the treated area too hard.
Mild sensitivity or redness
is a normal reaction.
It usually settles within 1 to 3 days. If symptoms are severe, contact the clinic.
We recommend a follow-up visit
to monitor your progress.
A periodic check is needed to confirm how the treated area has recovered and how well the whitening is holding.
One-Day Teeth Whitening Frequently Asked Questions
Browse the questions patients most often ask
before visiting Seoul Standard Dental Clinic.
How much brighter can my teeth get?
The degree of brightening depends on the original shade of your teeth and the cause of discoloration.
Before the procedure we check your current shade with a shade guide and explain the change you can reasonably expect.
Does teeth whitening cause a lot of sensitivity?
Your teeth may feel temporarily sensitive during or after the procedure.
This usually eases with time, but if it persists or is severe, contact the clinic.
How long do whitening results last?
How long results last depends on lifestyle factors such as coffee, tea, wine and smoking, and on your oral hygiene.
Cutting back on staining foods and drinks and keeping up regular care helps maintain a brighter shade.
Will my resin fillings or crowns get brighter too?
Whitening works only on natural teeth. The color of existing restorations such as resin, crowns and veneers does not change.
If there is a noticeable color difference after whitening, separate restorative treatment may be needed.
How is in-office whitening different from at-home whitening?
Under Ministry of Food and Drug Safety (MFDS) regulations, at-home whitening products are approved only up to 3% hydrogen peroxide, whereas in-office whitening uses a higher-concentration agent under a dentist's supervision together with gum protection, so the speed and extent of change differ (source: MFDS).
Another key difference is that the concentration and application time can be adjusted if sensitivity is severe.
Will whitening toothpaste make my teeth whiter?
It is unlikely to change the underlying shade of your teeth.
Toothpaste sold in Korea may contain no more than 0.75% hydrogen peroxide, so its effect is limited to removing surface stains and maintenance. Purple toothpaste works by color correction, making teeth look whiter optically (source: MFDS Standard Manufacturing Criteria for Quasi-drugs).
Will scaling (a dental cleaning) make my teeth whiter?
Scaling removes tartar and surface stains, returning teeth to their original shade. Its purpose is different from whitening, which brightens the tooth itself.
If staining is the cause, scaling alone may make teeth look brighter, but discoloration of the tooth itself is a matter for whitening.
