Hello, this is Lucid Dental Clinic.
Have you ever felt that your tooth color was subtly bothering you every time you smiled?
No matter how thoroughly you brush your teeth,
we often hear people say their confidence drops
because their teeth still do not look bright enough.
Especially if you have an important occasion coming up and want to create a bright, clean first impression, teeth whitening can be a good choice.
Today, we’ll explain teeth whitening in an easy way at the Nonhyeon-dong dental clinic.
Please read through it slowly and check whether this is a procedure you need :)

What is teeth whitening?
Teeth whitening is a procedure that uses whitening agents to brighten the surface of discolored teeth.
When pigment has become embedded in the teeth themselves, ordinary cleaning or scaling can be difficult to solve the problem, so a professional whitening process can help restore teeth to a brighter, cleaner appearance than before.
Whitening is not just a cosmetic improvement; it is also one of the treatments that helps brighten the overall impression.

Why do teeth turn yellow?
Aging
As you get older, the enamel becomes thinner and the underlying dentin becomes more visible, making teeth look yellow.
Smoking
Nicotine and tar in cigarettes stain the surface of the teeth and can cause them to turn brown or yellowish.
Staining foods and drinks
Strongly pigmented foods such as coffee, wine, cola, and curry repeatedly come into contact with the teeth and cause staining.
In particular, many people drink coffee often, so it is easy to be exposed to frequent staining.
Poor oral hygiene
If you do not have a good brushing habit or have not had scaling for a long time, tartar and stains can build up and make the tooth color look dull.

Teeth whitening, how is it done?
- Detailed examination
We identify the current condition of the teeth and the cause of the staining,
and predict the whitening effect.
If you already have restorations or fillings,
a color adjustment may also be necessary.
- Application of a protective agent
To protect the gums and soft tissues,
a protective agent is applied to minimize irritation from the whitening agent.
- Application of whitening agent and light exposure
After applying the whitening agent to the teeth, special light is used to help the whitening agent penetrate deeply.
This process is repeated 1 to 3 times and carried out gradually until the desired brightness is reached.
- Finishing and aftercare
For a certain period after the procedure, avoid strongly pigmented foods and smoking, and if necessary, additional whitening at 2- to 3-week intervals can lead to more satisfying results.

Teeth Whitening Q&A
Q. How long does the whitening effect last?
A. It depends on each person’s lifestyle habits,
but on average it lasts about 6 months to 1 year.
After whitening, avoiding staining foods,
and maintaining regular scaling and care can help it last longer.
Q. Is teeth whitening painful?
A. In most cases, there is no major pain, but
a temporary sensitive feeling may occur. This is a temporary
phenomenon, and it can be sufficiently eased
through protective agents and procedure adjustments.
Q. What is the difference between at-home whitening and in-clinic whitening?
A. In-clinic whitening uses a high-concentration professional whitening agent,
so the effect is faster and stronger. In contrast, over-the-counter products have a lower concentration,
so the effect is limited and may even damage the teeth.
Teeth whitening is not just about making teeth white;
it is a procedure that changes your overall impression and confidence.
However, since each person’s dental condition and the appropriate whitening method are different, accurate diagnosis and safe treatment are more important than anything else.
At our Nonhyeon-dong dental clinic, we provide customized teeth whitening tailored to each person’s condition, from detailed diagnosis to post-procedure care.
