Grinding, clenching and TMJ complaints

Many people clench or grind their teeth—often unconsciously, especially at night. Tension in the chewing muscles or complaints in the area of the temporomandibular joints are also common. There is not always a serious cause behind it, but persistent symptoms should be checked.

Typical signs may include:

• tense or painful chewing muscles
• a feeling of pressure in the jaw area
• clicking or rubbing in the temporomandibular joint
• morning pain in the face or at the temples
• headaches
• sensitive or worn teeth
• restricted mouth opening

What happens when you grind

With strong clenching or grinding, high forces act on the teeth, muscles and temporomandibular joints. This can lead to loss of tooth substance, fillings or dental restorations can be put under strain, and muscles become tense.

Stress, tension or unfavorable habits often play a role. Sometimes bite problems, sleep issues or other medical factors are also involved.

What can help

Often, a lot can be achieved with simple measures.

Bite guards made of transparent plastic protect the teeth from further wear and can relieve the temporomandibular joints and muscles. They are usually worn at night.
