Teeth whitening

I just had my scaling done recently.

It was okay back then.

 

Suddenly, I realized.

The teeth look yellow.

I'm feeling very anxious.

 

Because I really like coffee

Is it because of the coffee?

I'm not sure.

 

So, I think I should do whitening.

 

My gums are in poor condition.

I'm also worried.

 

I've heard that getting whitening treatment can cause tooth sensitivity.

I'm a bit 고민이 되네요.

 

Suddenly, my teeth look yellow.

I'm also concerned about what I say.

 

People who have received teeth whitening at the dental clinic

How effective is it?

 

Are you in pain?

And how many times should I receive it?
