Yellow teeth and tooth discoloration

Cosmetic dentistry and dental restoration for whiter teeth

Teeth whitening / AirNate / Scaling

Teeth are visible more often in everyday life than you might think.

Not only when you smile,

but also when you speak,

even when your expression is neutral, if your lips part slightly,

the color of your teeth becomes visible.

So when your teeth look yellow,

many people unconsciously cover them with their lips

or hesitate to smile openly.

If you have kept putting it off because you have been busy,

why not create a more confident smile this year

with brighter teeth?

The whitening method for yellow teeth

may vary depending on the cause.

Rather than trying to solve everything with just one procedure,

it is important to first determine why the teeth look yellow.

✿Check Point✿ Causes of yellow teeth

Yellow teeth are usually caused by acquired factors,

but there are more possible causes than you might expect.

Cause of yellow teeth 1. The thickness of the enamel and dentin

Teeth consist of the outer enamel

and the dentin inside it.

Enamel has a bright, translucent appearance,

while dentin naturally has a slightly yellowish color.

Therefore, if a person is genetically predisposed to have thicker dentin,

or if the enamel wears down and becomes thinner with age,

the teeth may look more yellow than before.

Cause of yellow teeth 2. Smoking

Smoking is difficult to overlook

as a major cause of yellow teeth and tooth discoloration.

The tar and nicotine in cigarettes

can easily stain the tooth surface

and may also be associated with plaque, tartar, cavities, and gum disease.

Cause of yellow teeth 3. Consuming strongly pigmented foods

Foods and drinks with strong pigments,

such as coffee, black tea, curry, chocolate, and red wine,

can leave color on the tooth surface,

making the teeth gradually appear darker.

Cause of yellow teeth 4. Consuming hot foods

Hot and stimulating foods, such as kimchi stew and ramen,

can affect the condition of the tooth surface

and make stains more likely to remain.

This is also why care after meals is important.

Cause of yellow teeth 5. Internal discoloration

In some cases, yellow teeth and tooth discoloration

are caused not by the outer surface

but by problems inside the tooth.

Cavities, trauma, necrosis of the nerves and blood vessels,

long-term medication use, or certain individual factors

may cause the tooth to darken from the inside.

Cause of yellow teeth 6. Accumulated tartar

Tartar is a yellow, calcified deposit formed

when plaque and various substances attached to the teeth harden.

It is difficult to remove with brushing alone,

and the teeth may look increasingly yellow as it accumulates.

As you can see, when the causes differ,

the solutions naturally differ as well.

✿Check Point✿ How to address yellow teeth caused by surface staining: professional teeth whitening

Teeth that look yellow because of surface stains

from inadequate oral care, smoking, or food consumption

can often be whitened through a relatively simple procedure.

In such cases,

high-concentration whitening agents and special light

can be used to brighten the teeth in a short period of time

while minimizing damage to the tooth surface.

Depending on the condition,

some people notice a visible change after just one treatment.

✿Check Point✿ How to address yellow teeth caused by internal discoloration: non-vital tooth whitening

When teeth look yellow because of internal discoloration,

a more careful approach is needed.

One common method

involves placing a whitening agent inside a tooth

that has undergone root canal treatment

to restore its brightness.

This method is commonly called non-vital tooth whitening.

Although it may be completed in one treatment,

an additional one to three treatments may be needed depending on the condition.

Rather than simply making the outside look white,

considering the cause of the discoloration

can help achieve a more natural result.

✿Check Point✿ How to address yellow teeth caused by enamel and dentin thickness: laminates

When the teeth naturally look yellow

because of differences in enamel and dentin thickness,

there may be limitations to conventional professional teeth whitening alone.

In such cases, cosmetic dental treatment

that can improve not only the color

but also the shape of the teeth

may be considered.

At 강남새로치과,

rather than excessive tooth reduction and unnatural restorations,

we take an approach focused on preserving a natural appearance

through minimally invasive laminates and AirNate, based on a no-prep approach.

Including the fabrication period for the dental restorations,

the overall process generally takes about one week

and may help create a brighter, more refined impression.

✿Check Point✿ How to address yellow teeth caused by tartar: scaling

When teeth look yellow because of tartar,

scaling is the first option to consider.

Scaling removes tartar accumulated on the tooth surface

and around the gums,

making the teeth look cleaner and brighter

and also helping prevent and manage gum inflammation.

Because it is covered by national health insurance once a year,

if there is not much tartar and it is limited to the area above the gumline,

scaling alone can make the overall appearance look much cleaner.

✿Check Point✿ Determine whether teeth whitening is suitable

Ultimately, the most important thing in teeth whitening

is first to accurately determine

why the teeth look yellow.

Whether it is simple staining,

internal discoloration,

tartar,

or the structure of the enamel and dentin,

the appropriate treatment can differ completely.

Therefore, even when there is only simple staining or internal discoloration,

if you are automatically advised to undergo restorative treatment,

you may feel dissatisfied after the treatment.

When the cause differs, the method should differ as well,

because this can lead to greater satisfaction with the result.

There are various ways to brighten the teeth,

but what matters is determining which method

is best suited to the condition of your teeth.

So if you want to address the cause of yellow teeth, the cause of tooth discoloration,

it is important to consider not only whether a clinic can simply make your teeth white,

but also whether it can recommend treatment suited to your current condition.

and provides consultations that naturally connect the most appropriate option

among teeth whitening, AirNate, and scaling.
