Sun damage

When you grow older, you can notice the rapid effects of sun damage on your skin such as moles and blemishes.

This damage from the sun is less effective on your face if you wear or have something that can protect you such as wearing a baseball hat and an umbrella.

Sun damage can cause harm on one side of your face which can result in a lopsided smile.


As mentioned before, smoking can cause you to have a lopsided smile since the toxins can rearrange the shape of your face. 

Dental work

When you had your tooth taken out, you will have some effects on your face that will make you have a lopsided smile.

The use of dental procedures can contort the shape of your face but it has been observed that these medical procedures can help straighten this asymmetrical smile. 

Some cases have observed that not all people who had veneers or other dental procedures were able to fix a lopsided smile.

A study on twins who had dental extraction and genetic background of this asymmetrical smile had this smile thanks to this extraction.

When you are getting older, you are more likely to have a lopsided smile.

You don’t have to worry since this is a typical aspect of being in the elderly age. 

Your bones might have stopped growing when you were undergoing puberty but your cartilage will continue growing as you get older.

In this case, your ears and face will grow which can make you have a lopsided smile.

Lifestyle habits

Some people believe that the practices of sleeping on your belly or with your face against a pillow, having poor posture, sitting with your legs crossed in the same direction for a very long time and resting your face against your hand can all cause the inevitability of a lopsided smile.

A study also found that sleeping on your stomach can make you have this asymmetrical smile.

Injury on your face in your childhood years can make a lopsided smile. This asymmetrical face can be caused by a broken nose or a deep cut on your face.

Bell’s palsy

If you suddenly have a lopsided smile, it means you might have an underlying physical condition.

Bell’s palsy is the paralysis of nerves that can disrupt some functions in the body and make deformations in other parts such as the face. 

Bell’s palsy can happen after pregnancy due to an infection but this tends to be short-term.

This physical condition can cause the muscles in the face to weaken which can cause a lopsided smile.

The drooping of the face is a symptom of a stroke.

If you feel that a side of your face is face and causes a lopsided smile, you need to seek medical help immediately. 

Other symptoms and signs of a stroke are muscle numbness and having trouble falling asleep.


Torticollis is called a twisted neck and may be a cause of a lopsided smile.

This physical condition can occur when you are still in the womb due to some closeness in the tight space.

Eye weaknesses can occur in the midst of torticollis.

This physical condition has symptoms and signs that only last for a short time. 

It is less typical for torticollis to happen in the long term.

How to test if your smile is symmetrical and not lopsided?

You can test if your smile is symmetrical and not a lopsided smile by finding materials that can help you realize that you have a certain smile.

You can evaluate a recent photo of you to check your smile.

Then, you could check some parts of your smile that could make it lopsided. You can use a mirror as well and check for the following markers:

  • the peak of your forehead and the bottom of your chin where you can set some points for vertical symmetry and one of the sides is horizontal
  • the crease on the far corner of both of your eyes
  • the crease of where each of your eyes starts next to the bridge of your nose
  • the crease where your lips start on both sides
  • the widest mark of both sides of your face
  • the largest section of your nose on both nostrils

You can use a ruler to mark some sides horizontally to check for a lopsided smile.

There are also apps that are free to use to check your asymmetrical smile. 

You need to be cautious about taking the results of your photos literally.

Computer apps can only do so much but they can’t measure the uniqueness of your face. 

A computer can’t always determine if you have a lopsided smile and a hint of attractiveness in that kind of smile.

How to cure a lopsided smile?

You can cure a lopsided smile by doing one of the following medical interventions.

Although this kind of smile doesn’t really warrant medical attention since this smile captures your uniqueness. 

Here are some cosmetic medical procedures that you can do to fix your lopsided smile.


Inserting a soft filler can fix your lopsided smile by inserting an injection.

This is why the use of Botox is very popular in this scenario where your face will be formed into the proper shape.

Fillers can help fix your lopsided smile as long as you keep addressing it.

This is because the effects of this medical procedure only work in the short term.

Facial implants

If you might be having a lopsided smile due to a skeletal dysfunctional, you can do facial implants.

These medical procedures can help you sort out your asymmetrical smile to a symmetrical smile. 

Facial implants have lasting effects and the kinds of these medical procedures are the following:

  • silicone
  • metals
  • plastics
  • gels
  • proteins
  • Rhinoplasty

If your lopsided smile is a cause of a broken nose, you can do a nose job using Rhinoplasty which can make you reform your face and your smile again.

You should take note that the effects of this medical procedure don’t last a long time.

Didn’t you notice that people smiling makes the whole room feel different?

It is a fact proven by science, that the smile and the good humor increase the antibodies and protect us from infectious, autoimmune and tumor diseases.

Many people wonder if anger, screaming and impatience are not needed to rebel against injustices, before those who break their word, before those who deceive, before those who commit atrocities before our eyes. 

One of the most famous books of antiquity, The Iliad, begins with Achilles’ anger at the injustice of Agamemnon.

But where does an epic full of war and death, of great and exceptional feats lead us? 

The greatest feat, and the best way to maintain health, is still to hold your posture and smile.

Even if it is a big smile, crazy smile, crooked smile, half smile, or sad smile – whatever you call it, the important thing here is to tell your brain that it is not the end of the world. 

Smiling revitalizes the mood and not only of the person smiling, but also that of everyone around him.

The art of the shaman, the jester, the psychiatrist and the good doctor, are in the fact that when faced with the most transcendental and serious positions in life, they know how to smile (and when not laugh out loud).
