What Causes Smile Fatigue?
A smile is said to be the most important cosmetic skill anyone can have. A smile is formed mostly by flexing the facial muscles in the side of your mouth. Some smiles form an involuntary contraction of those muscles in the upper corner of your eyes, a common action called a Duchenne smile. Some people with really big teeth (many dentists’ estimate that a person’s smile weight is half their body weight) and/or lots of gum tissue will smile with their mouth wide open even if they don’t feel like it, as the excess gum tissue relaxes and moves back into place with the closed mouth. The muscles in the gums also help to keep a smile from falling open wide.
The term ‘smile’ refers to any open, wide-eyed or smiling facial expression. It is the universal sign of happiness. Smiles are a natural response to someone else’s genuine smile, and when you smile at someone you like, it is a sign of love and a warm welcome to come across as a friendly stranger.
Smiles are contagious. If you smile at someone or hold doors for them, they might smile back at you. A smile is the best thing you can do for yourself, so it is worth your while to look after your teeth and smile often. But the problem is that smiling creates those ugly creases on your face, the wrinkles. The reason is simple; the smile is created by a muscle that controls the movement of your facial bones, the ligaments, and the underlying tissues of your face.
The frowning or raising of your eyebrows, the locking or closing of your mouth, the narrowing or flattening of your mouth, the rolling of your eyes, the expression of your mouth muscles, and even the folding of your mouth corners can all be created in the Zygomaticus muscles. That’s right, there are muscles that control your smile. And the wrinkles are born from those muscles not perfectly aligned. That’s why it is so important to be conscious of your posture when you smile. You have muscles that determine how you will be facing the other person, and this is why misalignment of those muscles, especially when you smile can create wrinkles.
Zygomaticus muscles are located on both sides of your nose, on the bridge and the denture area, on each side of your mouth, in the creases of your forehead, and between the incisors on each tooth. When you smile, those muscles contract, lengthen, rotate, and contract again. This smile pattern is called a smile. The teeth that are not smiling are referred to as biting teeth. When you are smiling, the corners of your mouth move up and down giving a certain appearance, depending upon the facial structure and the position of your jaw.
In addition to the muscles controlling the smile, the face also has structures that determine how much you smile. Your size, facial expression, and even the color of your skin can determine how much you smile and how your mouth moves. The corners of your mouth, known as’soft spots’, will become less prominent and more prominent, and your upper and lower lip will become more defined, giving you a more triangular shape. Dimples are the result of these changes.
