Does orthodontic treatment hurt a lot?

Orthodontic pain

Reasons for the pain and ways to reduce it

People considering orthodontic treatment

often ask before their consultation:

“Does it hurt a lot when you get braces?”

“Is it okay if my teeth feel loose?”

“Will orthodontic pain make daily life difficult?”

Because orthodontic treatment is not completed in a single appointment like cavity treatment,

but instead moves the teeth over an extended period,

it is natural to be concerned about pain.

However, orthodontic pain is often

a natural response that occurs as the teeth move,

rather than pain caused by damage to the teeth.

Gangnam Saero Dental Clinic

will explain in detail why orthodontic pain occurs,

the types of pain, and ways to reduce it.

Orthodontic Treatment Principles

Although teeth may appear to be firmly fixed in place,

there are actually periodontal ligaments and jawbone

around the roots of the teeth,

which can respond to subtle changes.

Orthodontic treatment uses this principle.

When a consistent force is applied through orthodontic appliances

in the direction the teeth need to move,

the periodontal ligament in front of the direction of movement is compressed,

while the periodontal ligament on the opposite side is stretched.

The jawbone then repeatedly undergoes resorption and formation,

allowing the teeth to gradually move

to their desired positions.

In other words, orthodontic treatment is not simply a matter of pushing the teeth into place.

It is a biological treatment

that uses the body's natural healing process.

Why Orthodontic Treatment Takes a Long Time

“Wouldn't applying stronger force

shorten the orthodontic treatment period?”

Some people may wonder this,

but tooth movement has

biological limits to its speed.

Teeth are generally known

to move approximately 1 mm per month.

Applying excessive force to move them faster

can cause problems such as:

Damage to the tooth roots

Tilting of the teeth

Damage to the gum tissue

Therefore, with orthodontic treatment,

it is important to move the teeth stably

while maintaining the health of the teeth and gums,

rather than simply trying to finish quickly.

Type 1. Pain Caused by Tooth Movement

This is the most common type of orthodontic pain.

As force is applied to the teeth

and the periodontal ligaments and gum tissue change,

you may experience:

A dull or aching sensation in the teeth

Discomfort when chewing

A slight feeling that the teeth are loose

A tingling sensation

These sensations may be more noticeable

when orthodontic appliances are first attached

or when new force is applied after a monthly adjustment.

In most cases, they gradually decrease within a few days as part of a natural process.

Type 2. Pain Caused by Orthodontic Appliances

Orthodontic appliances are attached inside the mouth

to continuously apply force to the teeth.

At first, the appliances may touch

the inside of the cheeks,

the inside of the lips,

or the tongue,

causing a foreign-body sensation or irritation.

Temporary mouth ulcers or sores may also occur.

These symptoms usually improve during the adjustment period,

but if the appliance continues to irritate a particular area,

it is advisable to have it adjusted at a dental clinic.

Type 3. Pain Caused by Correcting Malocclusion

Compared with routine alignment of the teeth,

correcting malocclusion such as protruding teeth or a protruding jaw,

an open bite, or a deep bite

can involve a more complex treatment process.

When the teeth need to move significantly

or the bite relationship needs to be adjusted,

you may experience:

Pressure on the teeth

Discomfort when chewing

Fatigue around the jaw

These symptoms may occur as the teeth move

to their proper positions.

Type 4. Pain Occurring During Space-Creation Procedures

If there is not enough space for the teeth to move,

space may need to be created.

Common methods include:

Extraction orthodontics

Interproximal reduction

Use of separators

In particular, separators involve inserting rubber rings

to create small spaces between the teeth.

During the first few days,

you may feel significant pressure or discomfort when chewing.

However, the symptoms gradually ease

once sufficient space has been created.

Ways to Reduce Orthodontic Pain

It is difficult to eliminate orthodontic pain completely,

but proper management can help reduce discomfort.

  1. Eat Soft Foods

Immediately after orthodontic treatment,

force has been applied to the teeth,

so it is better to eat soft foods

rather than hard or chewy foods.

  1. Care for Your Orthodontic Appliances

Food remaining around the appliances

can cause gum inflammation or additional discomfort,

so thorough oral care is necessary.

  1. Consult Your Medical Provider if the Pain Persists

The usual pain that occurs during orthodontic treatment

is different from pain caused by a problem.

If the pain continues for a long time

or only a specific area continues to hurt,

it is advisable to have it checked by a medical professional.

What Is More Important Than Orthodontic Pain

Because orthodontic treatment involves tolerating some discomfort,

what is even more important

is establishing the right treatment plan from the beginning.

Even with the same type of orthodontic treatment,

results can vary depending on:

The direction of tooth movement

The condition of the gums

Facial shape

The bite relationship

The desired direction of improvement

Rather than pursuing fast results at all costs,

an accurate diagnosis that considers

the patient's dental and facial balance

is important.
