Key Points for a Bright Smile

Teeth whitening cost

Causes of tooth discoloration

Even if it does not fit the generally accepted standard of beauty,

a bright smile is one of the most important elements

that can create a beautiful first impression.

If you smile showing all of your teeth

but your teeth are yellow,

you cannot leave a good impression.

That is why many people look into teeth whitening cost.

Depending on the cause of discoloration,

teeth whitening methods

and teeth whitening cost

also vary, so an accurate diagnosis of the cause is necessary.

✿Key Point✿ Causes of Tooth Discoloration

Teeth Whitening Effects According to the Causes of Tooth Discoloration (Teeth Whitening Cost) image 2

Tooth discoloration is divided into congenital and acquired causes.

Most tooth discoloration is caused by acquired factors,

and depending on the cause,

teeth whitening methods and teeth whitening cost vary,

as does the teeth whitening period.

✿Key Point✿ Cause of Tooth Discoloration 1

Teeth are made up of yellow-white dentin,

milky-white translucent enamel.

If, by nature,

the yellow-white dentin is

thicker than the milky-white translucent enamel,

the yellow-white color becomes more noticeable.

Or, through acquired causes,

the thickness of the milky-white translucent enamel

may become thinner,

making the yellow-white color stand out.

✿Key Point✿ Cause of Tooth Discoloration 2

The most representative acquired cause

of yellowing teeth is, of course, smoking.

Tar and nicotine, among the components of cigarettes,

can accumulate on the tooth surface,

causing discoloration.

Smoking is not only a cause of discoloration,

but can also cause plaque, tartar, cavities, and periodontal disease,

so it is best to quit smoking

for the health of not only your dental area

but also your overall health.

✿Key Point✿ Cause of Tooth Discoloration 3

Food is also one of the causes of tooth discoloration.

This is especially true for foods with strong pigments.

Black tea 12.73

Chocolate 11.03

Kimchi stew 10.59

Ramen 9.98

Soy sauce 8.5

Black coffee 8.42

Café latte 4.11

Red wine 4.11

Curry 2.33

Cola 2.0

This is the pigment staining index by food.

Foods eaten only occasionally

do not have a major effect on staining,

but if they are consumed continuously and brushing is not done properly afterward,

they can cause discoloration.

In particular, hot foods expand the tooth surface,

increasing staining ability,

so you need to pay even more attention to brushing.

✿Key Point✿ Cause of Tooth Discoloration 4

Cavities

Trauma

Genetic diseases

Excessive fluoride intake over a long period

Taking tetracycline antibiotics

Necrosis of the nerve and blood vessels inside the tooth

For the reasons above, it is possible for the inside of the tooth,

not just the outside,

to become discolored.

✿Key Point✿ Cause of Tooth Discoloration 5

Tartar, which is formed when plaque and other substances mix and calcify,

has a yellowish color.

It cannot be removed by brushing,

and it can form even if you brush regularly.

Not only does it have a yellowish tint,

it also makes the texture look poor.

✿Key Point✿ Teeth Whitening Method 1

Externally discolored teeth have simple causes,

so they can be treated relatively easily,

and the teeth whitening cost is the lowest,

while the teeth whitening period is the shortest.

Externally discolored teeth can be treated with a teeth whitening method called professional whitening,

which uses high-concentration whitening agents and special light

to produce results in just one day.

(However, continuous teeth whitening treatment

is needed to maintain the teeth whitening effect.)

✿Key Point✿ Teeth Whitening Method 2

Internally discolored teeth have complex causes,

so periodic procedures are needed,

and the teeth whitening cost is somewhat higher

and the teeth whitening period is longer.

Internally discolored teeth can be treated with a teeth whitening method called non-vital bleaching,

which involves making a hole inside the tooth and injecting a whitening agent,

then periodically replacing the whitening agent.

(After periodic procedures,

it is recommended to maintain the teeth whitening effect

with continuous teeth whitening treatment.)

✿Key Point✿ Teeth Whitening Method 3

Yellow teeth caused by thickness

cannot be treated with whitening agents alone.

The teeth whitening cost is high,

and the teeth whitening period takes about a week.

Yellow teeth caused by thickness can be treated with a teeth whitening method called laminates,

or Airenate, which attaches artificial restorations similar to natural teeth.

It is semi-permanent,

and can improve not only color but also the shape of the teeth.

✿Key Point✿ Teeth Whitening Method 4

Yellow teeth caused by tartar

require tartar removal,

and the teeth whitening cost is covered by health insurance once a year.

Yellow teeth caused by tartar

are treated with scaling,

a teeth whitening method that uses a scaler to remove tartar stuck to the tooth surface.

Scaling removes tartar,

can also make yellow teeth white,

and can prevent various periodontal diseases,

so periodic procedures are recommended.
