Why Is My Smile Crooked | How to Fix It

A crooked or a lopsided smile is pretty common; most people do not have complete facial symmetry.

Why is my smile crooked, and how do I fix it? If that is the question you’ve been asking, then this article is for you.

A crooked smile can also be a sign of a medical emergency in some cases. It can be caused by a variety of factors, the majority of which are not dangerous.

A sudden change, on the other hand, necessitates immediate medical attention.

This article will go over the causes of a crooked smile, the significance of a sudden lopsided smile, and when you should see a doctor.

What Does It Mean to Have a Crooked Smile?

A lopsided smile is one that is uneven. It appears uneven in that the left and right sides of the mouth do not match.

In a way that suggests a smile, one side of the face is pulled up; the other side is pulled down, possibly in a downturned manner.

What Causes Crooked Smile?

Well, a crooked smile can be caused by a variety of factors, including dental issues, nerve damage, stroke, and others.

Typically, the various causes are associated with additional symptoms in addition to a crooked smile.


A stroke is an acute type of brain damage caused by an interruption in blood supply in a brain artery. It can cause weakness of the face and body on one side, among other symptoms.

When a stroke symptom appears suddenly, it is a medical emergency. 

When you notice signs of a stroke, such as your face dropping or your smile becoming uneven, you should consult a doctor right away.

Numbness and difficulty speaking are other common symptoms of a stroke.

Bell’s Palsy

This particular form of facial paralysis or weakness only affects one side of the face. Common symptoms affecting the mouth include one corner of the mouth drooping and the smile line (nasolabial fold) disappearing.

On that side of the face, there will also be weakness in the forehead, eyelids, and cheek.

Bell’s palsy appears over a few hours and worsens for a few days. After a few weeks, it gradually improves, and it usually takes three to six months to return to normal.

It is unknown what causes Bell’s palsy. It often improves on its own, and oral steroids can sometimes help speed up recovery.

Facial Paralysis

Because of nerve or muscle damage, facial movements can become paralyzed.

Other causes of facial weakness besides Bell’s palsy, stroke, and nerve injury include:

Myasthenia gravis: This is a condition in which the immune system mistakenly attacks receptors required for muscle activation.

Multiple sclerosis: This is a disease in which the immune system attacks the protective myelin sheath of the nerves in the brain, spinal cord, and eyes.

Amyotrophic lateral sclerosis (ALS): This is a neurological disease that attacks the nerves that control movement.

Dental Structure

Many people are born with slightly or moderately uneven teeth. This does not usually result in a crooked smile.

Teeth can be naturally very uneven or become severely uneven as a result of dental conditions such as tooth decay. This can result in a crooked smile.

Jaw Structure

The jaw structure can result in a crooked smile from conditions like cancer invading the bone if the jaw bones or movement are formed unevenly or sustain damage from trauma or disease.


A twisted neck is a condition in which the person’s neck muscles are positioned incorrectly.

This condition can sometimes occur within the womb.

The majority of cases are temporary, and the symptoms can be resolved; it is rarely permanent.

A crooked smile or facial asymmetry can be caused by a variety of medical conditions.

Aside from health reasons, people may intentionally use a lopsided smile for a variety of reasons.


The nerve branches that control mouth movements may be damaged during surgery.

This can happen if surgery is required to remove a tumor or abscess that has grown into the facial nerve.

A surgical error can also result in the accidental transection of a nerve or nerve branch.


As you get older, your facial asymmetry worsens. As you age, your ears and nose naturally grow, resulting in asymmetry.

Sun Damage

As you get older, exposure to the sun and its UV rays may cause you to develop spots, patches, and moles on your skin. This can occur on one side or area of your face that has received the most sun damage.

Facial Injury

A facial injury can harm the nerves, muscles, bones, and other tissues. Swelling can also be significant.

This can result in a lopsided smile and an uneven facial appearance.

After the swelling subsides and healing is complete, the face and smile can return to normal.

A crooked smile can persist for a long time after severe trauma.

Symptoms of Crooked Smile

Symptoms associated with a crooked smile can include:

  • Flattening of the nasolabial fold
  • Slurred speech
  • Trouble chewing or swallowing
  • A droopy eyelid
  • An eyelid that can’t fully close

It is important to note that a sudden crooked smile could indicate a stroke, brain aneurysm, or infection.

This could last over the course of several hours. A new and rapidly worsening lopsided smile can occasionally be a sign of a tumor, cancer metastasis, or a seizure which is uncontrolled electrical activity in the brain.

When to See a Doctor

If, for some reason, your face or mouth suddenly feels numb, or if your movement appears uneven, seek medical attention immediately.

Symptoms of an uneven smile that necessitate immediate medical attention include:

  • Acute, severe headache
  • One-sided physical weakness
  • Loss of equilibrium
  • Vision shifts
  • One side of the face droops
  • Speech that is slurred
  • Injuries caused by trauma
  • Facial or neck swelling
  • the inability to control one’s facial movements
  • Facial or neck spasms
  • Eye pain or an infection of the eye

A smile can boost your self-esteem. However, you should only try to alter your smile if it is affecting your confidence.

Here are some methods for correcting a crooked, uneven, or lopsided smile:

  • Chew with both sides of your mouth.
  • Sleep on both sides at the same time.
  • Perform facial exercises.
  • Play around with your smile and find what works best for you.
  • Contour your lips with concealer.
  • To plump your lips, use a lip filler.
  • Get dental care

Again, if you are completely confident and comfortable with your smile, there is no need to change anything about it.

Treatment for a Crooked Smile

There are several techniques available for treating a crooked smile. There is a distinction between immediate and delayed treatment.

In an emergency situation like a stroke or severe facial trauma, immediate treatment focuses on preventing serious damage and minimizing long-term consequences. This could include things like blood thinners for stroke treatment or surgery for facial trauma.

After a lopsided smile has stabilized, treatment may include muscle training exercises.

This can be used to improve the appearance of the face as well as to prevent complications such as choking.

In some cases, Botox injections can paralyze specific muscles to prevent a crooked appearance of the mouth.

Surgical intervention may also be required to reconstruct facial nerves, muscles, bones, or other structures. This can help to make the face appear more even.

This type of surgery may also be effective in lowering the risk of certain complications, such as eye damage caused by an improperly closing eyelid.

Does Sleeping On Your Side Cause a Crooked Smile?

Some people believe that sleeping on your side, sleeping on your stomach, or sitting with your legs crossed for a long time can result in a crooked smile.

Some even believe that bad posture or resting your face on your hand can cause an uneven face.

But there is no basis for this, and it should be taken with a pinch of salt.

Why You Should Smile Regularly

Smiling can improve both your mood and your confidence. It creates a positive perception. It also has a variety of health benefits.

Examples include:

  • Blood pressure goes low.
  • Stress reduction
  • Immune system re-enforcement
  • It improves your mood.
  • Smiling is contagious; when you smile, others smile back. It helps you stay positive; when you are in a difficult situation and smile, it automatically lifts your mood and can help you deal with your problems.

Regardless of how forced, a smile is, it automatically sends a signal that you’ve got this and that things can turn out better with a positive attitude.

When you go for your interview, if you smile, you will most likely appear more confident. You will notice a difference.

Is a Crooked Smile Attractive?

A crooked smile can appear attractive at times. It adds to your charm if you use it at the right time and place.

It can give you the appearance of being easygoing and relaxed. However, crooked smiles can appear odd in some situations.

That’s when people try to fix it using various methods.


A crooked smile can be caused by a variety of medical conditions. A person’s smile may be uneven due to natural variations, but this is usually not a cause for concern.

Sometimes, a crooked smile could be a sign of a serious medical problem, such as a stroke or even an infection.

If you notice a sudden change in your facial appearance, seek medical attention right away. Other causes, such as Bell’s palsy or a misaligned jaw, may necessitate medical treatment to avoid complications.
