Jaw pain can be caused by a variety of factors, including temporomandibular joint (TMJ) disorders, teeth grinding, and rheumatoid arthritis. TMJ disorders are problems with the joints and muscles that control jaw movement, and they can cause a dull, aching pain in the jaw, as well as a clicking or locking jaw. Teeth grinding, or bruxism, can also lead to jaw pain and tightness. Additionally, rheumatoid arthritis, an autoimmune inflammatory disorder, can affect the jaw joint and surrounding tissues, causing tightness and pain in the jaw. To relieve jaw pain and tightness, there are several treatments available, including mouthguards, muscle relaxants, and botox injections. Self-care treatments such as applying heat or ice packs, massaging the jaw, and reducing stress can also help to reduce jaw tension and discomfort.

What You'll Learn

Reduce gum chewing and similar activities
Chewing gum and similar activities, such as chewing on pens or biting your nails, can lead to an overworked masseter muscle, resulting in either pain or hypertrophy of the muscle. Masseter muscle hypertrophy refers to the enlargement of the masseter muscle, which can cause a person's jaw to appear wide and their face to appear rectangular, leading to psychological distress.
To reduce gum chewing and similar activities, it is important to first become aware of these habits and address the behavioural patterns that contribute to overworking the masseter muscles. This may involve learning techniques for relaxation and stress management, as increased stress is often a contributing factor to these habits.
Additionally, seeking behavioural therapy or consulting a specialist can help address the underlying causes and provide guidance on reducing these habits. For example, a dentist may recommend a mouth guard to prevent teeth grinding, especially during sleep, which is a common cause of masseter muscle overwork.
In some cases, reducing the frequency of gum chewing and similar activities may be sufficient to reduce the size of the masseter muscle over time. However, if the issue persists or is causing significant discomfort or distress, further treatment options such as Botox injections or surgical procedures may be considered.

Address teeth grinding and clenching
Addressing teeth grinding and clenching (bruxism) is essential for maintaining oral health and reducing jaw muscle pain. Here are some ways to tackle this issue:
Mouth Guards
Dentists often recommend custom mouth guards to prevent teeth grinding and clenching, especially during sleep. While they may not entirely prevent the overgrowth of the masseter muscle, guards can help protect your teeth and reduce the full range of jaw movement. Mouth guards are particularly useful for those who grind their teeth at night, as it is challenging to control this unconscious habit.
Behavioural Therapy
Behavioural therapy aims to address the underlying habits that contribute to overworking the masseter muscles. This type of therapy helps individuals become aware of their teeth grinding or clenching and provides techniques for relaxation, stress management, and sleep hygiene. By learning to manage stress and anxiety, which are common causes of bruxism, individuals can reduce the frequency and intensity of teeth grinding.
Botox Injections
Botulinum toxin type A (Botox) injections are another treatment option for reducing jaw muscle contractions. These injections temporarily relax the jaw muscles and can help alleviate pain. However, repeat treatments are necessary, usually every three to four months, to maintain the results.
Dental Check-ups
Regular dental visits are crucial for monitoring dental health and treating any damage caused by teeth grinding. Dentists can provide guidance and interventions to manage bruxism and its associated symptoms.
Lifestyle Changes
Certain lifestyle changes can help reduce the frequency and impact of teeth grinding. These include practising mindfulness and stress reduction techniques, avoiding smoking, recreational drugs, and excessive alcohol consumption, and improving sleep habits.
In conclusion, addressing teeth grinding and clenching involves a combination of interventions, including physical protections like mouth guards, behavioural modifications, and, in some cases, Botox injections. By taking a comprehensive approach, individuals can effectively manage bruxism and reduce its impact on their oral health and overall well-being.

Perform jaw exercises
Performing jaw exercises is a great way to reduce the masseter muscles and sharpen your jawline. The masseter muscle is a powerful muscle that helps us chew and eat our food. It is located on both sides of the face and is responsible for elevating and protruding the lower jaw. Over time, habits such as chewing gum, biting nails, or teeth grinding can cause the masseter muscles to be overworked, leading to pain or muscle hypertrophy.
Jaw Release Exercise
Place your tongue on the roof of your mouth, right behind your upper front teeth. Allow your jaw to relax and your teeth to part slightly. This should be a natural, gentle relaxation. From here, you can perform two variations of this exercise:
- Partial Opening: Place your tongue to the roof of your mouth and position one finger in front of your ear, where your temporomandibular joint is located. Then, place the pointer finger of your other hand on your chin. Using your finger, gently drop your jaw halfway and then close it. Repeat this movement 6 times in 1 set and aim for 6 sets a day.
- Full Opening: Similar to the partial opening, but this time, use your pointer fingers to drop your jaw completely down and then back up.
Resisted Closing
Using your thumb and index finger of both hands, gently squeeze your chin. Open your mouth by dropping your jaw down and then close it while applying gentle resistance with your fingers. This exercise strengthens the jaw muscles and helps release any stress that may be causing you to clench or grind your teeth.
Neck Curl-up
Lie on your back with your tongue pressed against the roof of your mouth. Bring your chin to your chest and then lift your head off the ground about 2 inches. Keep your stomach relaxed and avoid poking your chin out. Start with 3 sets of 10 repetitions and gradually increase the number of sets and reps over time. You can perform this exercise in a seated, standing, or lying position.
Lip Lift
With your mouth closed, push your lower jaw out and lift your lower lip. Hold this position for 10-15 seconds, then relax. Perform 3 sets of 15 reps.
Smile Stretch
Smile as widely as you can, stretching your tight jaw muscles. Then, open your mouth until you feel a stretch or slight discomfort. Hold this position for 10 seconds and repeat 10 times.
In addition to these exercises, it is important to address any habits that may be contributing to overworked masseter muscles, such as gum chewing or teeth grinding. Reducing these activities can help prevent muscle hypertrophy and alleviate pain.

Consider Botox injections
Botox injections are a recognised treatment for reducing the size of the masseter muscle, which is the muscle responsible for elevating the lower jaw/mandible and assisting in the forward movement of the lower jaw. The masseter muscle can enlarge or bulk up due to being overworked, and this can cause a person's jaw to appear wide and their face to appear rectangular.
Botox injections are a minimally invasive treatment that is FDA-approved and generally very safe. The procedure does not require a hospital visit and is performed in a doctor's office. Before the procedure, a medical professional will clean your skin to reduce the risk of infection and may use a topical anaesthetic to numb the area.
The treatment uses botulinum toxin to temporarily block nerve signals in the masseter, which stops the muscle from moving. This weakening effect of Botox reduces the size of the masseter muscle, creating a slimmer, V-shaped jawline. Botox can also help to relieve the symptoms of teeth grinding and jaw clenching, also known as bruxism.
The effects of Botox are not permanent and usually last three to four months. After this time, many patients return for "maintenance" injections to extend the positive effects of the treatment. There is very little recovery time associated with Botox, and side effects tend to be mild, including some bruising or soreness around the injection site.

Improve your diet and exercise routine
Improving your diet and exercise routine can help reduce jaw muscle tension and improve your jawline definition.
Diet
A healthy, balanced diet is essential for maintaining a healthy weight and promoting overall health, including that of your jaw muscles. While diet alone may not directly reduce jaw muscle size, it can help prevent weight gain that may contribute to a fuller jawline.
Exercise
Exercising your jaw muscles can help build them up and improve jaw definition. Additionally, specific exercises can help relax tense jaw muscles and provide relief from conditions like TMJ (temporomandibular joint disorder) that cause jaw pain and tightness.
- Neck Curl-ups: Lie on your back with your tongue pressed against the roof of your mouth. Bring your chin to your chest and lift your head about 2 inches off the ground. Avoid lifting your stomach or poking your chin out. Start with 3 sets of 10 repetitions, gradually increasing over time.
- Tongue to Roof: Place your tongue on the roof of your mouth, behind your upper front teeth. Relax your jaw and allow your mouth to open naturally. For a partial opening, place one finger in front of your ear at the temporomandibular joint and your other hand's pointer finger on your chin. Drop your jaw halfway and then close. Repeat 6 times in 1 round and complete 6 rounds a day. For a full opening, follow the same steps but drop your jaw completely.
- Resisted Closing: Use your thumbs and index fingers to squeeze your chin, then open your mouth by dropping your jaw. Apply gentle resistance with your fingers as you try to close your mouth.
- Mouth Stretch: Smile as widely as you can, then open your mouth until you feel discomfort. Hold for 10 seconds, then repeat 10 times.
- Wall Stretch: Stand with your back against a wall and pull your chin toward it, creating an overbite and a double chin. Hold for 3-5 seconds and repeat 10 times.
In addition to these targeted exercises, regular exercise in general can help promote a healthy weight and improve your overall well-being, which can positively impact your jawline.
