Know This in Advance If You Don't Want to Waste Money on Teeth Whitening

Hello.

I am Kim Moo-jin, director of 디데이치과,

where we aim to provide treatments with minimal pain.

"If you just apply the whitening agent,

doesn't everyone get whiter teeth?"

To be honest,

no.

And because of this misconception,

there are people who spend a considerable amount of money

and then sigh in front of the mirror.

I had whitening done somewhere else,

but it had no effect on me. I spent all that money, too.

This is something I actually hear in the consultation room.

It's not just about the money.

When the few weeks spent waiting expectantly

end in disappointment, that feeling tends to linger even longer.

There is also the frustration of not knowing

whose advice to trust when advertisements are everywhere.

If you read this one article,

at least you may be able to avoid spending money

on whitening that will not be effective.

​1. Why does whitening have no effect on some people even when it is the same treatment?​2. There is an order to follow for whitening, too. ​3. At 디데이치과, we do not recommend whitening when it is unlikely to be effective​​
  1. Why does whitening have no effect on some people even when it is the same treatment?

If your friend’s teeth became noticeably brighter

after just a few sessions while yours look the same,

was the procedure done incorrectly?

It is more likely that the “cause”

of the discoloration was different.

If the discoloration is staining caused by pigments

from coffee, tea, wine,

or smoking accumulating on the tooth surface,

whitening tends to produce noticeable results.

However, if the outer enamel has become thin

with age, teeth grinding,

or improper brushing, the situation is different.

This is because the yellow dentin underneath

is showing through,

so there is a limit to how much brighter

the surface can become.

It is like washing an old white shirt with bleach:

it will not become like new.

That is because the fabric itself has faded.

Teeth that have darkened after root canal treatment

or due to the effects of antibiotics taken during childhood

are also difficult to whiten with whitening alone,

so a different approach is needed.

Therefore, rather than simply asking whether

you should get whitening,

you should first determine

which type of discoloration you have.

But in addition to identifying the cause,

there is one more step to complete before whitening.

  1. There Is an Order to Follow for Whitening, Too

Whitening agents work by penetrating the teeth.

Therefore, if you undergo whitening

while you have cavities or inflamed gums,

the agent may seep into those gaps,

which can lead to severe sensitivity

or damage to the gums.

An examination and any necessary treatment come first,

and whitening comes afterward.

Many people are also confused about the difference

between at-home whitening

and professional whitening at a dental clinic.

At-home whitening uses a lower concentration of whitening agent,

so it is safer but works more slowly.

Professional whitening uses a higher-concentration agent,

so it is important to proceed while checking

the condition of the teeth and gums.

And the process does not end when the procedure is over.

For several days immediately afterward,

you should limit foods that can cause staining,

and you should receive guidance on how to respond

if sensitivity occurs so that the results last longer.

At this point, you may be thinking:

How can I tell whether a clinic

takes care of all of these things?

  1. At 디데이치과, We Do Not Recommend Whitening When It Is Unlikely to Be Effective

The first thing I do during a whitening consultation

is not choose the whitening agent;

it is identify the cause of the discoloration.

And if the examination shows

that the results are likely to be minimal,

I tell patients honestly.

Even if it means not generating revenue immediately,

I believe that not recommending a procedure

that is unlikely to work is the right way to provide care.

Conversely, if your condition is one in which results can reasonably be expected,

we explain which method is appropriate,

how to reduce sensitivity,

and how to care for your teeth afterward

until you understand everything,

and only then begin the treatment.

A treatment that the patient does not understand

is not good treatment,

even if it is theoretically appropriate.

To summarize:

The success or failure of whitening is determined mostly

not on the treatment chair,

but by the diagnosis before treatment begins.

So that you will not have to say,

“Why am I the only one who saw no results?”

we will identify the cause from the beginning

and explain the possibilities honestly.

If you are concerned about the color of your teeth

every time you look in the mirror,

do not worry about it alone.

Start by finding out what type of discoloration you have.

That first step can help you save both money and time.

If you have any questions, please feel free

to contact us anytime.^^

Thank you for reading this long post.

Sincerely,

Kim Moo-jin, Director of 디데이치과
