Teeth Clenching

Difference Between Bruxism and TMJ disorders

Bruxism is often confused and misperceived by many as a reflex chewing action but in actual it is a habitual grinding or clenching of teeth which is subconscious. Bruxism is classified as a disorder which is characterized by the involuntary clenching or grinding of teeth, most commonly happen at night but there can also occur at the day time.

On the other hand TMJ disorder differs from bruxism. TMJ refers to a temporomandibular joint that is located on the either side of jaw connecting our jaw to the skull causing jaw movement. The patients suffering from TMJ disorder experience pain and discomfort in the joint area of the jaw and may find it difficult to move their jaws. Both Bruxism and TMJ disorders are considered inter-related disorders.

bruxism Suffer Chart

Bruxism affects almost 8-10% of the total population. It is characterised by teeth grinding and jaw clenching which cause wear and tear of teeth, disorders of jaw or TMJ (limited movement of the jaw) and headaches. Bruxism can occur is young and old alike but most commonly it is observed in people of age 25-44 years of age.

Classifications of Bruxism

Bruxism is divided into two types:

  • Awake bruxism: In this type of bruxism involuntary clenching of teeth and jaw brcing occur as a reaction to particular stimuli.
  • Sleep bruxism: this type of bruxism is characterized involuntary teeth grinding accompanied by rhythmic and sustained contractions of jaw masseter muscle.

Bruxism can cause headaches, earaches, chipped teeth, facial pains and chewed tissues inside the mouth. Chronic teeth grinding can lead to hypertrophy of masseter muscle which is the main muscle used for chewing and moving jaws. This muscle is located at the jaw’s angle. Due to teeth grinding, this muscle become stronger similarly as lifting of the weights make biceps stronger. As the masseter muscle becomes stronger, it causes more damage to the teeth due to clenching. Headaches and facial pains also get worse with the passage of time.

Causes of Bruxism

Though there are no definite agreed upon causes of Bruxism but it may trigger due to regular stress or tension in some people. Some other people may have a habit of teeth clenching but they never feel any kind of symptoms. There is a complicated combination of factors which can cause bruxism. These include:

  • The extent of stress you are experiencing
  • For how long and tightly you clench or grind teeth
  • Whether you have misaligned teeth
  • Your capability to relax in stressful situation
  • Type of diet you are taking
  • Your sleeping habits

For each person suffering from bruxism, the cause or combination of causes can be different.

Botox for Bruxism Treatment

Although Botox has been well-known for the cosmetic treatments, Botox is also known for treating numerous medical indication including Bruxism/TMJ disorders as it effectively relieves pain. Botox has become an important treatment for TMJ /Bruxism to relieve symptoms.

CosmeDocs has been successfully making use of Botox for treating Bruxism for many years with minimal risk of complications. Botox for bruxism treatment gives relief to the patients from jaw ache, soreness in the jaws, jaw tension and headaches. Along with relieving the pain, Botox also produce dramatic changes in the facial appearance in patients with long standing bruxism which has caused the masseter muscle to enlarge. Due to bruxism, often jawline become wider giving squarer appearance to the lower face. Bruxism treatment with Botox also softens the jawline giving it a softer and more aesthetically pleasing appearance often preferred by females as well as some male patients.

Botox treatment for bruxism involves injecting small quantities of botox in both sides of the jawline which shrinks the masseter muscles in jaws. With the passage of time, masseter muscle weakens and decreases in size (atrophy) giving a softer and more appealing appearance of the face along with decreasing teeth grinding and clenching.

It is important to note that bruxism treatment with botox does not help in breaking the habit of teeth grinding though it has been reported by many patients that they grind less after the treatment.
