The shape of the jawline is determined by the underlying bone structure and the surrounding muscles. While it is not possible to physically reshape the bones in the face through exercise, it is possible to strengthen and build up the surrounding muscles to create a more defined jawline. Certain exercises, such as neck curl-ups and tongue twisters, can help to achieve this. Additionally, the size and configuration of teeth play a role in defining the dimensions of the jawline, as they determine how the skin drapes over the facial structure.

What You'll Learn
The jawline is made up of bone and muscle
While the shape of the jaw is determined by genetics, it can be influenced by other factors such as development, weight, and teeth. For example, a diet of mostly soft, processed foods can result in a smaller jaw, as the jaw does not develop as much when we chew softer foods. This is why many people have their wisdom teeth removed—there is not enough room for them. As we age, the shape of our faces changes, and our teeth can wear down, allowing the jawbone to move up and back, causing the mandible to become more concealed by cheek fat pads.
The jawline can be exercised to improve its definition and strength. Exercises such as neck curl-ups and tongue twisters can strengthen the muscles in the jaw and give it a more defined look. However, it is important to note that certain exercises, such as mewing, where the tongue is placed in unnatural positions, may cause bite and speech problems and make teeth less aligned. Additionally, over-exercising the jaw can lead to problems in the TMJ area, causing headaches, teeth grinding, and jaw pain.
To maintain a sharp jawline, it is recommended to eat a healthy, balanced diet and engage in regular physical activity. Excess weight can contribute to changes in the shape of the jawline, and lifestyle changes can help mitigate this.

Genetics and ageing affect the jawline
The shape of an individual's jawline is influenced by genetics and environmental factors. The size of the bones, distribution of fat, and muscle composition in the facial region determine the jawline's form. Genetics play a significant role in the development of specific facial traits, but their influence on appearance is not absolute. For instance, the approach and habits of an individual can also shape their jawline.
Genetics influence the size of the jaw bone, which forms the foundation of the lower face. As people age, their jaw bone undergoes significant changes, contributing to an ageing appearance. Studies have shown that the jaw length decreases notably when comparing young and middle-aged individuals, while the decline in jaw height is more pronounced from middle age to old age. These changes result in a softer, oval-shaped lower face and sagging skin, affecting the overall ageing appearance of the neck and lower face.
Ageing also affects the angle of the jaw, leading to a loss of definition along the lower border of the face. This is partly due to bone resorption, which causes the posterior part of the jawline to become less defined. Additionally, the fat pads in the cheeks descend, contributing to the formation of jowls—a common consequence of an ageing jawline. Jowls are caused by a combination of factors, primarily gravity, along with a loss of collagen and elastin, which result in sagging skin along the jawline.
While genetics set the foundation for the jawline, lifestyle choices and habits can also impact its appearance. Excess fat around the jaw area can obscure the jawline, making it less visible. Mouth breathing, for example, can negatively affect the jawline and alter facial development, potentially leading to a double chin or misaligned teeth. On the other hand, maintaining proper tongue posture, such as resting the tongue against the upper palate, can positively influence the jawline's appearance.
Furthermore, targeted jawline exercises can sculpt and enhance the jawline's appearance. Facial muscles, such as the masseter and cheek muscles, have muscle memory, retaining their shape over time. Engaging in specific exercises, such as chin lifts, jaw stretches, and resistance training, can help define the jawline and improve its appearance.

Teeth determine the dimensions of the jawline
The jawline is determined by the underlying bones and muscles of the jaw, and teeth play a significant role in shaping the jawline. The mandible, or jawbone, is the largest and strongest bone of the facial skeleton. It hosts the lower teeth and provides structural support to the lower face and chin. The size and configuration of the mandible influence the positioning and alignment of the teeth.
Teeth contribute to the dimensions of the jawline by guiding the growth and development of the mandible. The length and width of the mandible are influenced by the size and arrangement of the teeth. In particular, the length of the mandible is determined by adding the distance between specific landmarks, such as the midpoint of the tragus and the soft tissue around the angle of the mandible. The width of the mandible is the distance between the two angles of the mandible.
Additionally, the size and shape of the dental arch, which accommodates the teeth, impact the overall dimensions of the mandible. The dental arch length and total teeth size space are crucial factors in preventing lower third molar impaction, a condition where the wisdom teeth do not have sufficient space to erupt properly. Disproportionate sizes of the teeth, arch, and jaws are influenced by both environmental factors and an individual's genetic makeup.
Over time, teeth can wear down, affecting the positioning of the mandible. This wear can cause the jawbone to move up and back, resulting in changes to the jawline. Furthermore, the presence or absence of wisdom teeth can impact the dimensions of the jawline. In modern times, due to the prevalence of processed diets, jaws tend to be smaller, and wisdom teeth often need to be removed due to a lack of space.
While the underlying bone structure and teeth play a significant role in shaping the jawline, it is important to note that the appearance of the jawline can be influenced by other factors, such as weight, age, and genetics. Facial exercises, a healthy diet, and regular physical activity can also help enhance the definition and overall appearance of the jawline.

Jaw exercisers can be harmful
The jawline is a combination of bone and muscle. While jaw exercises are meant to strengthen the muscles in the jaw, they can also be harmful in several ways.
Firstly, the jaw connects to the skull at the temporomandibular joints (TMJ). These joints are designed to give the jaw maximum freedom and strength, but this also makes them vulnerable, especially to repetitive high stress. Jaw exercisers that involve frequent or intense chewing motions can put excessive stress on these joints, potentially causing serious and permanent issues such as a slipped or displaced disk. This can lead to chronic pain and jaw injuries.
Secondly, the muscles along the neck and jaw are often underdeveloped and inhibited. As a result, performing jaw exercises too quickly or doing too many repetitions can cause neck strain and jaw pain. It is important to start slowly with jaw exercises and stop if you experience any discomfort or numbness.
Additionally, some jaw exercisers may not effectively target the desired muscles. For example, making major motions of the jaw with an exerciser may primarily build up the large muscles in the cheeks rather than the minor muscles in the jaw that contribute to a defined jawline.
Furthermore, while jaw exercises may provide some benefits, they are not a comprehensive solution. To achieve and maintain a healthy and youthful appearance, it is crucial to also practice good eating habits, engage in regular physical activity, and adopt other positive lifestyle habits.
Lastly, it is important to consult a healthcare professional or a neuromuscular dentist before starting any jaw exercise routine, especially if you are already experiencing jaw pain or other dental issues. They can advise you on the best course of treatment and help prevent potential harm.

Exercises to improve jawline definition
While it is impossible to fight ageing or genetics, certain exercises can help improve jawline definition and make you look younger. These exercises can subtly change your face, making your cheekbones sharper and your jawline more prominent.
One of the main reasons many people don't have a well-defined jawline is that their jaw didn't develop enough during their youth. This is often because they didn't chew enough hard foods.
Neck Curl-ups
- Lie down on your back and press your tongue to the roof of your mouth.
- Bring your chin to your chest, lifting your head about 2 to 3 inches off the ground.
- Slowly lower your head back down and repeat.
Chin-up Exercise
- Close your mouth and slowly push your jaw forward.
- Lift your lower lip and push up until you feel the muscles in your chin and jawline stretch.
- Hold this position for about 10 seconds before repeating the exercise.
Tongue Twister
- Place your tongue at the roof of your mouth, just behind your teeth.
- Press your tongue firmly against the roof of your mouth to create tension.
It is important to note that doing jawline exercises such as mewing, where you put your tongue in unnatural positions, may cause bite and speech problems and could make your teeth less aligned. Therefore, it is recommended to consult a specialist before starting any jawline exercises.

Frequently asked questions
A jawline is made up of both bone and muscle. The upper jaw (maxilla) and lower jaw (mandible) are bones that shape the middle and lower face, respectively, and support the teeth. The mandible is also supported by muscles that attach to various parts of the jawbone.
The shape of your jawline is largely determined by genetics and development, but it can be influenced by other factors such as weight, teeth alignment, and aging. While you cannot physically reshape the bones in your jaw, you can strengthen and build the jaw muscles through specific exercises, such as neck curl-ups and tongue twisters. These exercises can enhance the definition of your jawline and create a sharper appearance.
Yes, it is important to approach jawline exercises with caution. Excessive or intense exercises can strain the neck and jaw muscles, leading to pain and potential injuries. Additionally, certain exercises that involve unnatural tongue or jaw positions, such as mewing, may cause bite and speech problems and negatively impact teeth alignment. It is recommended to consult a healthcare professional or a specialist before starting any jawline exercise routine.
