Some people suggest that chewing gum may help you get a more defined or chiseled jaw. However, scientific research to support these claims is lacking.

Chewing gum, Jawzrsize, and mewing may give your facial muscles a slight workout, but they’re unlikely to create visible changes to your jawline. It’s not possible to target fat loss in any particular area. Additionally, the appearance of your jaw depends on your genetic bone structure.

Some people believe that strengthening the muscles used for chewing can lead to a toned jaw. But most of the chewing muscles are in your cheeks and neck.

Does chewing gum make your jawline stronger?

Chewing gum regularly may strengthen masticatory muscles. A small 2018 study found that chewing gum can improve masticatory performance related to function and strength in some people.

But this doesn’t affect the appearance of your jawline. Chewing gum only strengthens muscles in your tongue and cheeks, as one 2019 study indicates. In this study, chewing gum improved the swallowing and feeding functions.

Does chewing gum make your jawline sharper and more defined?

Chewing gum isn’t likely to sharpen or define your jawline because the muscles used for chewing are largely in the neck and cheeks.

Does chewing gum make your jaw bigger and more muscular?

Chewing gum won’t make your jaw bigger or more muscular for the same reasons mentioned above. Most of the muscles used for chewing aren’t in the jaw.

Chewing gum occasionally doesn’t pose many health risks. But if you chew too much gum too often, there are potential side effects.

Excessive gum chewing can overwork and strain your facial muscles, leading to pain, tightness, and headaches. It can also cause

Chewing gum with sucrose can cause enamel demineralization and cavities, especially if you chew it frequently and for long durations.

Chewing gum containing acids for flavoring may lower your plaque PH levels, which can lead to:

  • enamel demineralization
  • cavity lesions
  • enamel erosion

There are several ways to enhance your jawline. You can choose a natural approach that involves losing weight through exercise and a healthy diet. Aesthetic and surgical procedures can also change the appearance of your jawline.

Read on to take a look at some of your options.

Balanced diet and weight loss

To lose weight, try to consistently burn more calories than you consume. Reduce your caloric intake and do physical activity to increase the number of calories you burn. You can use a journal or app to track your daily food intake, physical activity, and weight.

You’ll lose weight throughout your entire body, even if you do exercises that focus on specific areas of your body. This is because your body burns free fatty acids and glycerol for energy, which can come from anywhere in your body.

Follow a balanced diet consisting of:

  • vegetables
  • fruits
  • lean proteins
  • whole grains
  • low-fat dairy
  • healthy fats

Some of the best foods for losing weight include avocados, cottage cheese, and salmon.

Avoid processed foods, sugary foods and drinks, and fried foods.

Botox and dermal fillers

To make your jawline appear smaller, you can get Botox injections into the masseter muscles. A few weeks later, the muscles may be softer and relaxed, leading to a slim, defined facial shape. To maintain results, you’ll need treatment every 6 months.

Injecting jaw fillers can improve definition, symmetry, and balance with immediate results. These dermal fillers may remove jowls while adding volume and sharpness to the jawline. Results typically last 12 to 18 months.


Kybella is an injectable technique that zaps fat underneath the chin. Deoxycholic acid kills fat cells under your chin, making it unable to store fat. You may need up to five Kybella treatments.

Thread lifts

A thread lift is generally a more affordable option than injectable fillers, and is considered non-invasive.

The process involves inserting sutures under your skin that lift and tighten your face. The sutures activate your body’s healing process, stimulating collagen production in the treated areas. The results typically last 6 to 12 months.

Surgical options

There are several surgical procedures available. They’re ideal for people who have a rounded jawline with a moderate-to-large amount of fat and loose skin. These are considered invasive procedure that’ll require general anesthesia.

Surgical options include:

  • Neck lift. Offering the best long-term results, neck lift surgery tightens skin, removes fat from under your chin, and defines your jawline.
  • Neck liposuction. This procedure removes fat from your jawline and neck, tightens your skin, and defines your jawline. Results may be permanent.
  • Fat grafting. This technique injects fat from another area of your body into your face. It increases the volume, tightness, and overall appearance of your skin. It can also sharpen and define your jawline.
  • Chin augmentation. This procedure enhances the shape of your chin and lower jawline. It involves silicone implants or manipulation of the jaw bone.

There isn’t research to support chewing gum to define your jawline. While it isn’t likely to cause any major health concerns, chewing gum for extended periods may lead to strain and discomfort.

There are other proven ways to change the shape of your jawline.

If the appearance of your jawline is a cause of concern for you, you may wish to speak with a medical professional.
