To exercise your jaw, try simple movements like exaggerating vowel sounds ("O," "E"), performing chin-ups (push jaw forward and lift lower lip), and gentle resistance exercises (opening/closing mouth against your hand) to improve mobility, relieve tension (TMJ), and build definition, always moving gently and stopping if you feel pain. Incorporate tongue placement, jaw stretches, and side-to-side movements for a well-rounded routine, focusing on consistent, mild effort.
The idea of toning and defining the jawline through exercises is appealing, and, it's true, that like any muscle in the body, exercising the facial muscles can make them stronger. That said, unfortunately, there is very little scientific evidence supporting the effectiveness of jawline exercises.
How do I carry out the exercises?
While moderate use of these jaw exercises may help define your jawline and facial muscles, they could be harmful if overdone. Most orthodontists and dental professionals have studied the different ways these techniques can impact your oral health and jaw functions, especially if you practice them too much.
While changes to your face due to genetics or aging are perfectly natural, there are some exercises you can do to help define your jawline. Exercising the neck, chin, jaw, and other facial muscles can lead to subtle changes in your face, including sharper cheekbones and a more prominent jawline.
Among the most popular and effective methods to improve a weak chin or jawline are dermal fillers, Botox® Cosmetic, RF microneedling treatments, and implants. The best choice for you will depend on your specific concerns and the results you hope to achieve.
Some researchers have concluded that these exercises are an effective way to reduce wrinkles and sagging skin. For example, van Lieshout et al9 reported a direct correlation between improved skin elasticity in weakened and sagging facial skin and increased facial muscle exercise (FME).
Chewing gum can slightly strengthen your jaw muscles with consistent use over time, but it has minimal impact on actually changing or defining your jawline.
The 3-finger jaw test is a simple self-screening tool to check your jaw's range of motion (Maximal Incisal Opening or MIO) by seeing if you can comfortably stack three of your own fingers vertically between your upper and lower front teeth; fitting three fingers generally indicates a healthy opening (around 40-60mm), while struggling to fit two or fewer fingers suggests potential jaw restriction, often from muscle tension, clenching, or Temporomandibular Joint (TMJ) issues.
Jawline exercises like chin lifts and jaw clenching tone jaw muscles. Chewing sugar-free gum strengthens jaw muscles over time. Mewing (correct tongue posture) can improve jaw definition. Facial massage reduces puffiness and improves circulation.
While some are blessed with an angular, noticeable jawline, most of us aren't. This difference is because your facial structure is determined predominantly by genetics. This genetic code defines the width and prominence of your mandible, also known as a jawbone.
There are many reasons a double chin may occur. It can be due to constant weight gain or weight loss, causing looser skin under the chin. It can also form due to the effects of aging. A double chin (submental fat) is a problem many patients wish to resolve.
Best Jawline Exercises for Definition
When you look from the front, the line from the tip of the chin out to the mandibular angle is strong and smooth. The mandibular angle itself is well-defined, but it does not look bottom-heavy. When you look from the side, the lines from the chin down to the neck are seamless, and there is no fat or double chin.
Make an “O” shape with your mouth, covering your teeth with your lips. Place your fingers beside your mouth on your cheek area. With gentle pressure, lift your fingers out and upward toward your ears and hold for 5 seconds. Repeat this exercise 7-10 times for the best results.
So far, three risks stand out as the most common. Dentists have identified issues with changing bite positions, temporomandibular disorders (TMD), and gastrointestinal damage. All three have serious dental consequences if left untreated.
Exercising Your Facial Muscles
If your jaw imbalance is due to a weak chin, exercise can help to strengthen the muscles in your face and improve your appearance. In general, these exercises involve moving your lower jaw back and forth or side to side.
A weak jawline is defined by its rounded angle and soft edge. A common characteristic among those with a less pronounced jawline is that the mandible, the lower jaw, is often set further inwards – towards the neck – rather than outwardly protruding.
Growth spurts during childhood—especially around ages 6–12 and again in puberty—are when the jaw changes most rapidly. By the time your child is 12–14 years old, the upper jaw (maxilla) has typically finished growing, while the lower jaw (mandible) may continue developing into the late teen years.
Jaw tension can be a physical reflection of:
How often should you perform facial exercises? If you want to see results quickly you should aim to perform your facial exercises 3-5 times a week from around 20 minutes each time. If you don't have 20 minutes to hand, try splitting the time into 10-minute sessions that can fit more flexibly around your schedule.
