Recent neuroscientific research suggests that jaw exercises can provide some surprising health and cosmetic benefits.
Leading experts in the field frequently advocate for jaw exercises to improve breathing, sleep, facial attractiveness, and more.
In this post, we will explore evidence-based jaw exercise workouts, recommendations, and the scientific rationale behind them.

Jaw Exercise Benefits
The book “Jaws” by Sandra Kahn and Paul Ehrlich explores the impacts of mouth breathing versus nasal breathing on jaw development and facial structure.
The key takeaway is that proper tongue posture and chewing throughout childhood promote the growth of a prominent jaw structure.
Additional benefits of strong jaw muscles include:
- Opening of nasal airways, reducing mouth breathing
- Less risk of snoring and sleep apnea
- Strengthening the immune system
In his book Breathe, Author James Nestor recommends taping the mouth shut at night to shift from mouth breathing to nasal breathing.
Combined with chewing exercises, this can help transform jaw aesthetics.

Jaw Exercise Workout

The best jaw workout focuses on the masseter muscle used for chewing.
Since modern diets lack hard, chewy whole foods, this muscle often remains underdeveloped.

Chewing Mastic Gum
Since modern diets lack hard, chewy whole foods, this muscle often remains underdeveloped.
To train the masseter, experts recommend chewing mastic gum.
- 15x harder texture than regular gum
- Promotes mewing
- Sugar free
- Loses flavor quickly
- Not as durable as mastic gum
This helps exercise and develop the jaw muscles.
Using a Jaw Exerciser Device
Another recommendation from some experts is to use a jaw exerciser device.
This allows you to directly target and train the masseter muscle in the jaw.
Jawzrsize and other products provide adjustable resistance to progressively build strength.

Moving to Harder Chews and Heavier Equipment
Over time, its advised to move on to harder chewing gums and heavier jaw exercise equipment.
The goal is to continually increase resistance to encourage muscle growth.
This builds both strength and endurance in the masseter and jaw structure.

FAQ
Does jaw exercise really change facial aesthetics?
Yes, studies have found measurable cosmetic changes to jaw and facial structure from consistent mastication exercise over time. However, genetics also plays a key role.
What risks are associated with jaw training?
Excessive training could damage teeth enamel or contribute to acid reflux. Start slowly and avoid overexertion.
How quickly will I see results?
Some experience visual changes in as little as 30 days. However muscle growth and tone improvements take months for full effect. Remain consistent.
