Here is information about Gangnam teeth whitening.

White, evenly aligned teeth

play an important role in creating

a bright and neat impression.

Especially the impression made by teeth when smiling

can have such a strong effect that it can influence likability.

That is why, recently,

not only celebrities but also ordinary people

have been showing growing interest in

methods related to teeth whitening,

such as whitening procedures and toothpaste.

However, since toothpaste needs to be used consistently,

if you want to make your teeth whiter as quickly as possible,

you may want to consider teeth whitening

offered at places like our Seoul Centum Dental Clinic.

Through Gangnam teeth whitening,

we will explain how quickly teeth can become brighter,

as well as the method and how long the results last.^^

Why do teeth turn yellow?

If yellowed teeth that have been noticeable

from some point suddenly start bothering you,

it can keep weighing on your mind endlessly.

Originally white teeth can begin to become stained due to various factors,

and the surface of the teeth may gradually turn yellow.

Check whether you are unconsciously

doing things that make your teeth yellow.

Reasons for tooth staining
✅ Dietary habits If you consume foods with strong pigments such as curry, coffee, or wine, pigment deposition occurs on the tooth surface. If you do not brush well or do not clean thoroughly between teeth, tartar can form and the likelihood may increase further.
✅ Aging As you age, the function of the teeth gradually weakens, and the enamel also begins to thin. At this time, the dentin becomes more visible, which can make teeth appear yellow.
✅ Medication and genetics Taking antibiotics such as antihistamines or tetracycline can cause tooth discoloration. If these medications are taken at a young age, the tooth color may change more severely. Also, if the dentin is naturally thick, teeth may appear yellow.
✅ Lifestyle habits Smoking can be considered the biggest issue. Nicotine and tar in cigarettes are highly likely to cause staining on the tooth surface and also affect oral health.

If you want to regain white teeth,

teeth whitening!

Teeth whitening is a treatment that

returns the color of the teeth

to their original shade

or makes them whiter in a brighter tone.

Our same-day teeth whitening procedure

uses a high-concentration whitening agent

(containing about 15% hydrogen peroxide)

and special light to achieve

high results in a short time.

Compared with conventional whitening procedures

that required 2 to 3 visits,

you can see satisfying whitening results in just one day.

Because of these advantages,

we strongly recommend Gangnam teeth whitening

to those with important schedules ahead,

such as weddings, interviews, or events!

Procedure for same-day teeth whitening

① Scaling (if needed)

In areas with tartar,

hydrogen peroxide cannot properly penetrate.

If teeth whitening is performed in this state,

the teeth may become blotchy,

so if there is tartar before whitening treatment,

it is best to start with scaling first.

② Tooth surface cleaning

The area to which the agent will be applied is cleaned

to make it clean and smooth.

This helps the whitening agent be applied properly.

③ Application of the agent

A mouth opener is used to keep the mouth open,

gauze is placed to protect the gums,

and a gum protectant is applied to the gums

to reduce irritation,

after which the dental whitening agent is applied.

④ Laser light exposure

To activate the whitening agent applied to the gums,

a laser light device is used to expose it

three times for 8 minutes each.

⑤ Comparison of before and after differences

Photos are taken after the procedure

to compare the results with before treatment,

and depending on the outcome and level of satisfaction,

a decision is made on whether to proceed with additional teeth whitening.

Do you happen to know

how long teeth whitening lasts?

It is generally good to know that it tends to last about 2 to 3 years.

However, since everyone’s dietary habits

and lifestyle habits are different,

the exact duration cannot be said to be the same for everyone.

Therefore, depending on the degree of tooth staining,

the recommended whitening cycle is every 3 to 6 months

or every 6 months to 1 year.

(Individual differences may occur. ^^)

Just because you had Gangnam teeth whitening,

if you continue your usual lifestyle habits,

the duration of the effect is likely to become shorter.

Therefore, you should be aware of the precautions and follow them.

(1) For 48 hours after whitening,

this is the time when the effect is maintained best,

so please avoid foods or drinks that stain easily.

(Coffee, curry, wine, chocolate, grape juice, black tea, etc.)

(2) Please avoid foods that are too cold

or too hot for a while.

(3) Because whitening agents are used,

a temporary sensitivity reaction in the teeth

may occur.

In most cases, this naturally eases within 2 to 3 days,

so there is no need to worry too much~

(4) Please get scaling at a dental clinic 1 to 2 times a year

and be sure to brush thoroughly.

(5) Please refrain from smoking for at least 2 weeks

to prevent tooth staining.

Whether it has been a few days or a few weeks since tooth whitening,

if you consistently make efforts such as using whitening toothpaste

or quitting smoking,

you can enjoy the whitening effect for longer.
