Does Chewing Gum Tone Facial Muscles? What It Can and Cannot Do
Chewing gum is often promoted online as a free, easy way to sculpt a sharper jawline, tone the face, or get rid of a double chin. The idea sounds logical: chewing works muscles, and working muscles makes them stronger. But the face is more complicated than that. Social media videos make it look like an easy hack.
Chewing gum does work the muscles you use to chew, mainly the masseter and temporalis, but there is no good scientific evidence that it tones the face, lifts sagging skin, or reduces a double chin. In some people, heavy chewing may enlarge the jaw muscles or strain the jaw joints.
Most of what makes a face look sculpted comes from bone structure, fat distribution, and skin elasticity, not the size of the chewing muscles. Chewing does not burn meaningful fat from the face, and the muscles involved are not the ones that cause sagging.
Excessive gum chewing can cause problems. A 2014 study in Pediatric Neurology by Watemberg and colleagues found that among 30 teenagers with frequent headaches who chewed gum for hours each day, 26 improved after stopping, and 19 had their headaches resolve completely.
This guide explains what chewing does to facial muscles, why it does not slim the face, the risks of heavy gum chewing, and approaches that are more likely to help the look of your jawline. It also looks at trends like mewing and jaw trainers.

Key Takeaways
- Chewing gum works the jaw muscles but does not tone the face overall.
- There is no good evidence that gum chewing slims the face or reduces a double chin.
- Heavy chewing may enlarge the masseter muscles, making the jaw look wider in some people.
- Excessive gum chewing can strain the jaw joints and has been linked to headaches in teenagers.
- Facial shape depends mainly on bone structure, fat, and skin elasticity.
- Overall weight, posture, and skincare have more effect on jawline appearance.
- Jaw pain, clicking, or locking should be checked by a dentist or doctor.
Which Muscles Chewing Actually Uses
Chewing relies mainly on four pairs of muscles: the masseter at the angle of the jaw, the temporalis at the side of the head, and two deeper pterygoid muscles. These muscles move the lower jaw up, down, and side to side.
The muscles responsible for facial expressions, such as those around the mouth, eyes, and cheeks, are different. They sit just under the skin and are not strongly worked by chewing gum.
Sagging in the lower face and jawline is mostly caused by loss of collagen and elastin, fat pads shifting and shrinking, bone changes with age, and gravity. Strengthening the chewing muscles does not reverse these changes.
This is why chewing gum can make your jaw muscles feel tired without making your face look more lifted or toned.
Facial expression muscles are also attached directly to the skin, which is why repeated expressions create lines over time. Strengthening them does not smooth those lines; in some cases, frequent movement deepens them.
Why Chewing Gum Does Not Slim the Face
The idea that chewing gum slims the face is based on the assumption that working a muscle burns the fat around it. This is called spot reduction, and research on the body has shown it does not work. Fat loss happens across the body, not just where muscles are exercised.
Chewing gum also burns very few calories, so its effect on overall body fat is minimal. Face fullness, including a double chin, depends mostly on genetics, overall body weight, and age-related changes.
A bigger masseter can make the face look wider. In some people, very frequent chewing or teeth grinding can enlarge the masseter muscles, giving a squarer lower face. This is the opposite of the slimmer look many people want.
Some people do notice their face looks slightly different when they lose weight overall, which is a more reliable way to reduce facial fullness than any chewing habit.
Risks of Chewing Too Much Gum
Chewing gum occasionally is generally harmless. Chewing for hours each day can cause problems for some people.
- Jaw joint strain: the temporomandibular joints can become sore, click, or feel tight.
- Headaches: a 2014 study found that stopping excessive gum chewing reduced headaches in most teenagers studied.
- Muscle tension: overworked jaw muscles can feel tight and painful.
- Digestive symptoms: swallowing air and sugar alcohols in sugar-free gum can cause bloating or loose stools.
- Dental issues: sugary gum can contribute to tooth decay.
Stop chewing gum if you notice jaw pain, clicking, locking, or frequent headaches, and see a dentist or doctor if symptoms continue.
People who already grind or clench their teeth, often during sleep or stress, are more likely to develop jaw problems from heavy gum chewing. A dentist may suggest a night guard to protect teeth and joints.
Check Whether Gum Is Straining Your Jaw
If you chew gum often, this quick check can help you spot early signs of strain.
Track how much you chew
Note how many hours a day you chew gum over a typical week.
Check for jaw symptoms
Open and close your mouth slowly. Notice any pain, clicking, popping, or limited movement.
Feel your jaw muscles
Press gently on the angle of your jaw and the sides of your head. Tenderness suggests overuse.
Notice headaches
Record whether you get headaches, especially at the temples, on days you chew more.
Take a two-week break
Stop or reduce gum chewing for two weeks. If symptoms improve, frequent chewing may be a factor.
If you chew gum for fresh breath or to curb snacking, try limiting it to 15 to 20 minutes after meals.
Chewing Gum vs Other Approaches for a Defined Jawline
| Approach | Evidence for jawline effect | Notes |
|---|---|---|
| Chewing gum | None for slimming or lifting | May enlarge jaw muscles or strain joints |
| Overall weight management | Can reduce facial fat | Face often changes with body weight |
| Sun protection and retinoids | Help preserve skin firmness | Slow collagen loss |
| Posture awareness | May improve how the jawline looks | Forward head posture can emphasize a double chin |
| Facial exercises | Limited, small studies | Results modest and inconsistent |
| Professional treatments | Some have good evidence | Examples include fat reduction treatments or fillers |

What Is More Likely to Help Your Jawline
Good Habits
- Protect skin from the sun every day.
- Use a retinoid to support skin firmness.
- Maintain a healthy weight through diet and activity.
- Stand and sit with your head aligned over your shoulders.
- Stay hydrated and get enough sleep.
Common Mistakes
- Chew gum for hours hoping to slim your face.
- Use jaw exercisers that strain your joints.
- Expect exercises to replace skin care.
- Clench your jaw to build muscle.
- Ignore jaw pain or clicking.
Massage techniques such as gua sha may temporarily reduce puffiness around the jaw, which can make the jawline look sharper for a few hours. Our guide on whether daily face massage is good for skin covers realistic expectations.
If you want to reduce jaw fullness caused by enlarged masseter muscles, a dermatologist or cosmetic doctor can discuss options such as neuromodulator injections, which relax the muscle. This is a medical procedure with its own risks and should be done by a qualified professional.
Puffiness, Fluid, and the Lower Face
Sometimes the lower face looks fuller because of fluid retention rather than fat. Salty meals, alcohol, poor sleep, and hormonal changes can all cause temporary puffiness.
Reducing salt, staying hydrated, sleeping with your head slightly raised, and gentle lymphatic massage may help reduce puffiness. Our guide on lymphatic facial massage explains how to do it gently.
Persistent, one-sided, or painful swelling of the face or jaw is different and should be checked by a doctor or dentist.
Morning puffiness that settles during the day is usually harmless and related to fluid shifts while lying down.
Mewing, Jaw Trainers, and Other Trends
Chewing gum is one of several jawline trends. Mewing, which involves pressing the tongue against the roof of the mouth, and silicone jaw trainers designed to be chewed are also widely promoted online.
There is little quality research showing that mewing changes the adult face. Some orthodontic approaches can influence jaw growth in children, but these are carried out by specialists and are very different from social media trends.
Jaw trainers work the same chewing muscles as gum, but with more resistance. Dentists have raised concerns that they may overload the jaw joints and teeth, especially in people with existing jaw problems.
If you are interested in changing your jawline, a dentist, orthodontist, or dermatologist can explain realistic options based on your anatomy rather than online trends.
Be cautious with any trend that promises dramatic facial changes without professional involvement.
Real Benefits of Sugar-Free Gum
While gum does not sculpt the face, sugar-free gum has some genuine uses. Chewing stimulates saliva, which helps neutralize acids and wash away food particles after meals.
Sugar-free gum, especially with xylitol, is often suggested as a way to support dental health between brushing, and many dental organizations recognize chewing sugar-free gum after meals as a helpful habit.
Gum can also freshen breath, help some people manage snacking, and relieve ear pressure during flights. The key is moderation, and choosing sugar-free options to protect your teeth.
Avoid gum if you have jaw pain or a dental appliance that it could damage.
What Chewing Gum Cannot Do
| Belief | Reality |
|---|---|
| Gum chewing slims your face | No good evidence; spot reduction does not work |
| Gum tones sagging skin | Sagging is mostly skin and fat changes, not muscle |
| More chewing means better results | More chewing may strain joints and enlarge jaw muscles |
| Gum reduces a double chin | Double chins depend mostly on genetics and weight |
| Jaw exercisers are safe for everyone | They can worsen jaw joint problems |
Chewing gum can be useful for fresh breath and, if sugar-free, may help reduce cavities, but it is not a facial fitness tool.
Enjoy gum for what it is good for, and look elsewhere for facial sculpting.

- Difficulty opening your mouth fully.
- Frequent headaches, especially at the temples.
- Teeth grinding or clenching, especially at night.
- Swelling on one side of the face or jaw.
- Pain when chewing.

The Bottom Line
Chewing gum works the muscles used for chewing, but there is no good evidence that it tones the face, lifts sagging skin, or reduces a double chin. Facial shape depends mainly on bone structure, fat, and skin elasticity, and spot reduction does not work.
Chewing gum for hours a day may enlarge the jaw muscles and strain the jaw joints, and has been linked to headaches in teenagers. For a more defined jawline, focus on sun protection, skincare, healthy weight, and posture, and see a dentist about any jaw pain.
