What is the real reason they do not become brighter even with diligent brushing?

Have I been neglecting my usual dental care?

Why yellow teeth do not become brighter even after using whitening toothpaste

The tailored truth according to a Gaepo-dong dental clinic

Hello, I am Dr. Yuna Kim, director of Claire Dental, helping you regain your bright confidence.

There is something I hear several times a day:

"Doctor, I do not even drink coffee, so why do my teeth keep becoming yellow?"

“I really use whitening toothpaste three times a day and rinse between meals, too.”

“I am so stressed that people might think I do not brush my teeth.”

Many people say that when they look in the mirror or take photos, they cannot smile brightly and end up subtly covering their mouths.

In fact, tooth color has a greater impact on first impressions than we may think.

Over many years of treatment, I have seen countless times how a single set of clean-looking teeth can brighten an expression, with that small change leading to greater confidence.

So I would first like to be honest with you.

In fact, when dealing with yellowing, the results may depend less on how white the teeth become than on accurately understanding why they changed color.

Whitening that overlooks the cause may brighten the teeth only temporarily, after which they can quickly return to their previous shade or leave you with sensitivity. This is why I look into the cause before examining the color.

Some teeth can become brighter

The causes of yellow teeth can first be broadly divided into two categories.

One is surface staining, in which pigments from food and beverages seep into the outer surface.

At this stage, improvement in tooth color can be expected through a teeth-whitening process for yellow teeth.

On the other hand, caution is needed when the outer surface has gradually worn away, allowing the yellow dentin inside to show through.

In this case, simply brightening the teeth by breaking down pigments has limitations.

It may be a sign of tooth decay or gum disease rather than simply a cosmetic issue.

That is why Claire Dental, a Gaepo-dong dental clinic, first carries out a thorough analysis of your oral health.

A new standard for yellow-teeth whitening,

Claire Blanc

In addition to techniques for whitening teeth, our clinic operates a whitening program that also takes dental health into consideration.

Claire Blanc is a professional whitening-agent program developed directly by our clinic to meet both of these conditions.

It began with the idea that whitening yellow teeth should not be the sole goal, and that dental health should be considered as well.

First, a customized whitening agent is prepared with an optimal formulation suited to each individual's tooth condition, so improvement in color may be expected from the first treatment, depending on the condition of the teeth.

The process is designed not only to remove discoloration but also to protect and strengthen the tooth surface.

It was developed with the goal of reducing sensitivity.

In addition, the long-lasting whitening coating is intended to reduce the possibility of re-staining.

We also record the tooth color before and after treatment and provide it in the form of a certificate.

We record and explain the progress before and after treatment.

Leaving it in a document rather than just putting it into words—

this is my philosophy toward whitening.

Rather than providing a brief period of whiteness, the treatment is customized so that it can remain a satisfying choice over time. I personally conduct a detailed diagnosis of each patient's oral condition and the depth of the discoloration before proceeding.
