Temporomandibular joint (TMJ) disorders

TMJ, also known as TMDs, are the most common causes of pain in your jaw and affect as many as 10 million Americans.

Temporomandibular joints are the hinge joints on each side of your jaw. It involves the joint that connects your skull and jaw. There is a disc that separates the bones in this joint and helps it move properly.

If this disc becomes misaligned or the joint gets damaged, you could experience pain on one side or both sides of the jaw.


Commonly known as teeth grinding is probably the most well-known factor that causes jaw pain in people. It refers to grinding or clenching of the teeth, serving no function, that continues over time, and causes a person’s jaw to hurt. It stems from severe stress and anxiety.

Grinding or clenching of one’s jaw leads to damage and destruction of their teeth, infections in gum, and fatigued jaw joints.

This grinding usually occurs during the night when the person is sleeping, as it’s easier to control it during the day. A person suffering from this will wake up complaining of jaw pain on one side or both of them.


A lot of factors contribute to having sinus issues. It could be because of allergies, medical conditions, or if you’ve has a cold. The inflammation in your nasal cavities can cause sinusitis.

If the sinus cavities behind your cheeks, known as the maxillary sinuses, are inflamed, you might feel pain in one or both sides of your jaw.

Dental issues

This is a given that if you’re facing pain in your jaw if it’s gradual or sudden, it can be traced to dental or oral health concerns.

Different causes include cavities, an abscessed tooth, wisdom tooth, gum disease, tooth decay, missing or misaligned teeth, or tooth grinding.

They will definitely impact your jaw the most, from your gums to your teeth, destroying your bones and tissue of the mouth.

6 tips if your jaw is hurting

If you have mild or slight pain on one side of your jaw, there are things you can do at home to provide relief to it. You wouldn’t need medical treatment for temporary pain, but treating it at home and then visiting your doctor to find out the cause will do the trick.

1. Heat or ice packs

This is for immediate relief purposes when using either a heated or an ice pack to nurse your jaw.

If you don’t have an ice pack, you can take the ice in a plastic bag, wrap it in a cotton cloth, and use it for nursing for around 10-15 minutes. Then let it rest for 10 minutes and repeat the process 2-3 times.

Using a warm pack, just run a towel in hot water, squeeze all excess water, and then use it on the jaw area. It helps with muscle relaxing and relieving your jaw from pain. Make sure it isn’t cold or warm in the extreme to hurt your skin.

2. Medications

Obviously, medicines like acetaminophen (Tylenol), ibuprofen (Advil), and other over-the-counter pain medications can help relieve pain. But only for some time, after the pain has subsided, it’s better to see your doctor.

3. Soft food

Chewing hard food can make things worse for you and your jaw. So, try to eat soft foods as this will help keep the pain away. This won’t put stress on your jaw at all, and so your jaw muscles can remain as relaxed as possible.

4. Massage

A woman is getting a special massage treatment specifically on her jaw, for her constant jaw pain.

You can even provide some relief by massaging your jaw. All you need to do is use your index and middle finger to press onto the sore areas, such as the area before your ear where your jaw joints meet.

Rub in a circular motion 5-10 times, rest and open your jaw slowly and close it again. Repeat this exercise.

5. Relaxing techniques

Try to relax your jaw as much as you can. This includes trying not to clench or grind your teeth. This can be made far easier if you try to calm down your stress and anxiety, which can be worked upon by meditation and yoga.

6. Sleeping position

Maybe try a different type of sleeping position or change your mattress. This can help you immensely in providing relief to your jaw. Switching your sleeping positions can help your jaw muscles relax and not put too much pressure on one particular side.
