Chewing gum is marketed as a way to enhance one's jawline and facial aesthetics. However, there is little evidence to support this claim. While it is true that chewing gum can strengthen the masseter muscles, it does not significantly alter bone structure or fat distribution, which are the primary determinants of facial aesthetics. In fact, excessive chewing can lead to an enlarged masseter muscle, resulting in a fuller, more square-shaped jaw, often referred to as chipmunk cheeks, which may not be aesthetically desirable. Furthermore, prolonged gum chewing can lead to strain, discomfort, and other health issues.

What You'll Learn
Masseter muscle hypertrophy
While the condition is not life-threatening, it can cause psychological distress due to the altered appearance of the face, making the jaw appear wide and the face rectangular or square-shaped. This can create a more masculine look, particularly in female patients, or a bottom-heavy appearance. In cases of unilateral masseter hypertrophy, it can also cause jaw asymmetry.
There are both conservative/non-surgical and surgical approaches to treating masseter muscle hypertrophy. Conservative therapies include splint therapy, which uses oral appliances to reduce biting forces from clenching and grinding, and behavior therapy, which helps patients address behavioral habits that contribute to overworking the masseter muscles. Surgical treatments involve intraoral and extraoral approaches, with debulking of the masseter muscle or removal of excess bone to produce atrophy in the muscle.
Chewing gum companies often claim that their products can help tighten facial muscles and enhance one's jawline. However, there is limited scientific evidence to support these claims, and excessive chewing may lead to overdeveloped masseters, resulting in an undesirable square or bulky jaw appearance rather than a more defined jawline. While chewing gum may strengthen the masseter muscles, it does not change the underlying bone structure or significantly reduce facial fat.

Potential health risks
While chewing gum can lead to muscle hypertrophy, there are several potential health risks associated with this practice. Firstly, excessive gum chewing can cause strain and discomfort in the facial muscles, leading to pain, tightness, and headaches. This can also lead to an overdeveloped masseter muscle, resulting in an undesirable square or bulky jaw appearance, often referred to as "chipmunk cheeks".
Secondly, the act of repeatedly chewing gum is a form of resistance exercise for the masseter muscles, and as with any muscle in the body, consistent resistance training can lead to hypertrophy or muscle enlargement. While this condition is not life-threatening, it can cause psychological distress due to the exaggerated appearance of the muscle, resulting in a wider, more rectangular face.
Thirdly, the Temporalmandibular Joint (TMJ) is a delicate joint that can be affected by excessive gum chewing, leading to issues such as headaches, jaw pain, and clicking when opening the mouth. Additionally, chewing gum with sucrose can cause enamel demineralization and cavities, especially with frequent and prolonged chewing.
Finally, while rare, it is important to rule out other potential causes of facial swelling, such as muscle tumors, salivary gland disorders, or other growths in the head and neck region.
It is worth noting that the potential health risks associated with chewing gum for muscle hypertrophy purposes may vary between individuals, and some people may not experience any adverse effects. However, it is always advisable to consult with a healthcare professional before starting any new health or fitness routine.

Effect on facial aesthetics
Although chewing gum can cause muscle hypertrophy, it is unlikely to produce dramatic changes to one's facial aesthetics. While it can lead to a slight increase in muscle size and strength, the overall appearance of the jawline is primarily determined by bone structure, fat distribution, and skin elasticity, which chewing gum cannot significantly alter.
Some people believe that strengthening the muscles used for chewing can lead to a more defined jawline. However, most of the chewing muscles are located in the cheeks and neck, and consistent gum chewing may only result in a slight enlargement of the masseter muscles, which could create a fuller, more square-shaped appearance at the back of the jaw, often referred to as "chipmunk cheeks". This is supported by a study that found that prolonged gum chewing can increase masseter muscle thickness by approximately 15% after two months of intensive chewing, but these changes were more measurable by ultrasound than visibly apparent.
Additionally, excessive gum chewing can lead to overdeveloped masseters, which may not be aesthetically desirable and can sometimes result in a more square or bulky jaw, rather than the defined, angular jawline that many people seek. Furthermore, it can cause strain and discomfort in the facial muscles, leading to pain, tightness, and headaches.
While there is limited research on the topic, some experts suggest that facial exercises and aesthetic treatments, such as Botox injections, are more effective ways to add definition to the jawline. However, it is important to note that the appearance of one's jawline is also influenced by genetic bone structure, and surgical procedures are available for those seeking more significant changes.

Non-surgical treatments
While there is some evidence that chewing gum can lead to muscle hypertrophy, this is not a dangerous condition and is more likely to cause psychological distress due to the change in facial appearance. Hypertrophied masseter muscles can cause the jaw to appear wider and the face more rectangular.
There are non-surgical treatments available to reduce the appearance of hypertrophied masseter muscles:
- Splint therapy: Using an oral appliance to reduce the force of biting and grinding.
- Behaviour therapy: Addressing habits that may be contributing to overworking the masseter muscles, such as gum chewing, and learning techniques for relaxation and stress management.
- Thermal therapy: Applying heat or ice to sore muscles.
- Sleep hygiene: Improving sleep habits.
- Dietary counselling: Adjusting diet to reduce muscle strain.
- Botox injections: Botulinum toxin type A injections can be used to reduce muscle contractions and slim the jawline.
It is important to note that the effectiveness of these treatments may vary between individuals, and it is always recommended to consult a medical professional for advice.

Limitations of studies
While some studies suggest that chewing gum can lead to muscle hypertrophy, the research in this area is limited and mostly focused on clinical applications rather than cosmetic outcomes. Here are some detailed points outlining the limitations of these studies:
- Lack of Robust Scientific Evidence: The claim that chewing gum can lead to muscle hypertrophy and a more defined jawline is not supported by robust scientific evidence. Most of the claims are anecdotal rather than based on rigorous scientific research.
- Small Sample Sizes: Some studies have small sample sizes, which may not be representative of the general population. For example, a study by Kiliaridis et al. (1995) involved only 19 individuals, with a mean age of 25.4 years.
- Short Study Duration: Many studies examining the effects of gum chewing on muscle development are conducted over a short duration, such as a few weeks or months. For instance, Kiliaridis et al. (1995) and Ohira et al. (2012) reported improvements in bite force and masticatory function after a 4-week chewing exercise, but the long-term sustainability of these effects is unclear.
- Individual Variations: Individual responses to gum chewing can vary significantly based on genetics, starting muscle size, and other factors. Some people may experience more noticeable muscle development than others, and the aesthetic outcomes may differ.
- Clinical Focus: Most research on masticatory muscle development focuses on clinical applications, such as improving masticatory function and bite force, rather than cosmetic outcomes. The cosmetic effects of gum chewing on the jawline are often secondary to the clinical benefits.
- Ultrasound Measurements: Some studies rely on ultrasound measurements to detect changes in muscle thickness. While ultrasound can detect small changes in muscle size, these changes may not be visibly apparent or align with desired aesthetic goals.
- Bone Structure and Fat Distribution: The overall appearance of the jawline is influenced by factors such as bone structure, fat distribution, and skin elasticity, which gum chewing cannot significantly alter. Enlarged masseter muscles may not create the desired slim and defined jawline but may instead result in a fuller, more square-shaped appearance.
- Health Risks: Excessive gum chewing for extended periods can lead to health issues such as muscle strain, discomfort, headaches, and jaw pain. Therefore, the potential health risks associated with long-term gum chewing should be considered when interpreting the results of these studies.
