Hello.

We are The Square Dental Clinic, where we first look at the starting point of change.

Want to Make Yellow Teeth White? Before Self-Whitening image 1

When yellow teeth start to become noticeable, many people first think of self-whitening.

It makes sense to want something simple you can do at home that might brighten your teeth.

But in reality, the change is often smaller than expected,

and there are many cases where people do not notice much difference even after spending time on it.

Why does this difference happen?

The issue is not simply the method.

It is because the direction of treatment changes depending on where the tooth color change began.

So today, before considering self-whitening, I will explain the first 기준 you should separate and look at.

Even when teeth look equally yellow, the causes begin differently. If you want to make yellow teeth white, look at this first before self-whitening.

The reasons teeth change color can be broadly divided into two types.

First is extrinsic staining.

This is when foods with pigments, such as coffee, tea, or wine, build up on the surface of the teeth and change their color.

The change may be noticed relatively quickly, and it tends to remain on the outer surface of the tooth.

On the other hand, intrinsic discoloration begins from a different process.

This is when changes develop inside the tooth,

and it can appear in teeth that have had root canal treatment or teeth whose structure has changed over time.

Because the color changes from inside rather than on the surface,

the overall tone may look darker, or only a specific tooth may appear different.

Even if these two look similar from the outside, the direction of approach is different.

That is why it is important to first distinguish which process the change you see now began from.

Self-whitening does not produce the same result for everyone. If you want to make yellow teeth white, look at this first before self-whitening.

Self-whitening uses ingredients in the hydrogen peroxide family to break down tooth stains.

Simply put, think of it as something that helps clear away surface stains.

So if the discoloration is from extrinsic staining, where color has built up on the tooth surface, you may notice some brightening.

But if the change starts from inside the tooth, as with intrinsic discoloration, the situation is a little different.

In that case, the color has formed within the tooth structure,

so it is often difficult to feel a major difference with self-whitening alone.

In particular, if only one tooth looks different in color or the tooth gradually becomes darker over time, it is worth taking a closer look.

So before choosing a method, you need to first check which process your current condition belongs to.

Before whitening, you need a basis for judgment. If you want to make yellow teeth white, look at this first before self-whitening.

Before thinking about how to brighten tooth color,

it is better to first separate your current condition and think it through.

If you only focus vaguely on the color, it becomes a little difficult to judge which direction is right.

First, it is good to lightly check whether the color you see now is a change that has built up on the surface.

If you usually drink coffee or tea often, there is a chance the discoloration is caused by color building up on the tooth surface.

On the other hand, if only a specific tooth looks especially dark, or if you notice a gradual color difference over time, it may be a different process.

Whether the change is even across the whole tooth or only different in one area naturally leads to different approaches.

Another point worth checking is when this change started.

Whether it felt sudden or has been building up slowly over time, the 기준 you consider will also differ a little.

As you go through this process, you will likely be able to organize more clearly which side your current condition is closer to.

What you need now is not a choice, but a 기준 for looking at your condition properly.

[There is a reason everyone is not the same]

Just because your teeth look different in color does not mean you need to decide something right away.

At this stage, it is more about identifying where this change began.

Even if they look similar on the outside, depending on how the change was created inside, the direction you should consider can be completely different.

That is why, when looking at yellow teeth, you should first check the "starting point" rather than the visible color.

Once this point is distinguished, it becomes easier to organize which side your current condition is closer to and what you should consider next.

What you need now is not a rushed decision to change things, but to establish a 기준 that helps you understand your condition.

Before changing the color, please first check why that color was created.
