Orthodontic side effects

Protruding teeth, sunken lips, a longer-looking jaw, nasolabial folds, a peanut-shaped face, a longer philtrum

Orthodontic facial changes

The reason people start orthodontic treatment is

to improve crooked teeth or a misaligned bite

and achieve positive facial changes.

However, when you look at cases of negative facial changes after celebrity orthodontic treatment,

it may seem that orthodontic facial changes do not always

lead to positive results, so there may be people who hesitate to get orthodontic treatment.

If you have appearance-related insecurities caused by your dental structure

and need positive facial changes,

or if you need only changes to your tooth structure

without facial changes,

I hope this post helps you choose the right orthodontic treatment.

Principles of dental orthodontics

If you first understand the principles of dental orthodontics,

it will be easier to understand orthodontic facial changes.

The principle of dental orthodontics is to attach appliances,

apply pressure from the appliance in the desired direction of movement,

and then, in the direction of that pressure,

compress the periodontal ligament in front and resorb the jawbone,

expand the periodontal ligament behind and generate jawbone,

repeating this process until dental orthodontics is achieved.

Principle behind protruding teeth and sunken lips

Negative orthodontic facial changes include

protruding teeth and sunken lips.

As seen in the principle of dental orthodontics,

the process requires compression and expansion of the periodontal ligament,

as well as resorption and formation of the jawbone.

But if insufficient time and excessive pressure are applied instead of adequate time and consistent pressure,

the periodontal ligament and jawbone cannot withstand the pressure,

and compression and expansion, resorption and formation become inadequate,

causing the crowns of the teeth to move instead of the roots.

As a result, the teeth tilt forward,

which becomes protruding teeth,

and because of protruding teeth,

the lip line becomes sunken inward like the witch in a fairy tale,

which becomes sunken lips.

Causes of a longer jaw appearance

An orthodontic facial change that can be either positive or negative is

a longer jaw appearance.

The treatment approach for protruding mouth and underbite cases is different,

so for protruding mouths that are often accompanied by a receding chin,

using a dental orthodontic method that lengthens the jaw can actually be positive.

On the other hand, for an underbite where the lower jaw protrudes,

using the orthodontic method used for protruding mouths

can lead to negative orthodontic facial changes.

Causes of nasolabial folds, peanut-shaped face, and longer philtrum

There are also reviews of negative orthodontic facial changes such as

nasolabial folds, a peanut-shaped face, and a longer philtrum.

These may be temporary phenomena

or optical illusions,

but they can also be attributed to not establishing a treatment plan

that comprehensively considers the patient’s skeleton, skin, muscles, and structure.

Causes of positive orthodontic facial changes

Therefore, to achieve positive orthodontic facial changes,

a precise treatment plan must be created

by comprehensively considering the patient’s skeleton, skin, muscles, and structure

after evaluating the patient’s specific skeletal condition.

For example, if a treatment plan for protruding mouth correction

is designed using an underbite correction method,

it can lead to a negative result that makes the receding chin even more pronounced.

Conversely, if an underbite correction plan

is designed using a protruding mouth correction method,

it can lead to a negative result with no change in the underbite.

If a treatment plan is promoted with an emphasis only on fast orthodontics

and applies excessive pressure without sufficient time,

it will lead to negative results such as protruding teeth and sunken lips.

Treatment plans that consider only the teeth

can also cause nasolabial folds, a peanut-shaped face, and a longer philtrum.

That is why,

when it comes to dental orthodontics,

you should not go to just any clinic.

You need to find a clinic specialized in orthodontics

that can create a thorough treatment plan

based on expert orthodontic knowledge.
