Trismus caused by inflammation resolves by itself in due course, without need of any intervention. Whereas, when there is infection, trismus persists for a prolonged duration and it may even aggravate. This can be controlled by prescribing antibiotics.
Common medications for trismus include muscle relaxers and nonsteroidal anti-inflammatory drugs (NSAIDs) to relieve pain. Depending on the severity of the symptoms, a doctor may prescribe oral medications or drugs that require injection into the jaw.
Symptoms include the reduced range of motion you experienced, pain or cramping in the jaw that occurs with or without movement, and pain or difficulty when exerting pressure, as when eating. Whether or not your jaw problem is due to TMD or trismus, we urge you to see your doctor or a TMD specialist for diagnosis.
The hallmark of a masticatory space infection is trismus or infection in anterior compartment of lateral pharyngeal space results in trismus. If these infections are unchecked, can spread to various facial spaces of the head and neck and lead to serious complications such as cervical cellulitis or mediastinitis.
Physiotherapy treatments may be required to establish normal function (exercises will include neck stretching, chin tuck, massaging of masticatory muscles, and other jaw stretching). Mandibular opening devices might be considered in some cases, but most likely provided by a physiotherapist or dental specialist.
Generally, trismus is gradually alleviated or disappears within approximately 1 to 2 weeks post-operatively; however, in very rare cases, trismus persists for >1 month. The present study reports the case of a patient who exhibited trismus for 45 days following mandibular third molar extraction.
One simple test is the 'three finger test'. Ask the patient to insert three fingers into the mouth. If all three fingers fit between the central incisors, mouth opening is considered functional. If less than three fingers can be inserted, restriction is likely.
Patients need to know that trismus that occurs 1 year after treatment will be permanent and that there is no good surgical or medical therapy. Aggressive encouragement will lead to good compliance with trismus exercises and a low incidence of severe trismus, even after surgery and radiation.
Advil, Motrin or Ibuprofen can also help to improve swelling and jaw stiffness. Patients should perform exercises to gently stretch their mouth open to get it moving again. It can be tempting just to not open it wide at all, but that can lead to permanent limitation of opening (“chronic trismus”).
In contrast there are six so-called muscle relaxants (cyclobenzaprine, methocarbamol, metaxalone, ophendrine, chlorzoxazone, and carisoprodol). These drugs are primarily used to treat painful musculoskeletal conditions, which exhibit muscle spasms, secondary muscle guarding, bracing, tightening, or trismus.
Trismus has also been defined as mouth opening less than 40 mm; others have defined it as an opening to 15 to 30 mm, or even less than 20mm. Additionally, other authors have graded trismus according to visual assessment of mouth opening (light/moderate/severe or grades 1 to 3, again corresponding to mouth opening).
Trismus is a classical symptom of masticatory space infections and it can be a sign of an infection in the anterior compartment of lateral pharyngeal space. Common causes in clinical practice followed by trismus are odontogenic infection which can be periodontal or pericoronal.
Sugar free chewing gum may be helpful to keep your jaw moving.
Trismus can reduce the ability to eat and speak. Patients with trismus may have difficulty performing and receiving dental care. There are a variety of massages and exercises you can perform to prevent trismus.
The causes of limited mouth opening include trauma, infection, temporomandibular joint disorders (TMDs), neurological disorders, rheumatoid arthritis, drugs, tumors, hyperplasia of the coronoid process, etc. This condition can interfere with various medical treatments that require access to the oral cavity.
Trismus can be caused by damage to the muscles and/or nerve responsible for opening and closing the mouth and for chewing.
Applying a warm compress to your jaw and/or neck. Doing this several times a day for around 20 minutes per session can help relieve muscle stiffness by encouraging more blood to flow to your jaw. You can use a heat pack, hot water bottle, or warm towel. Applying a cold compress to your jaw and/or neck.
Whatever the cause, treating jaw stiffness – first with ice packs, then heat, then physical stretching – you can correct the trismus sooner and return more quickly to pain-free laughing and living.
In case of trismus associated with systemic symptomatology and other apparently unconnected clinical signs, a life-threatening pathology such as tetanus must be promptly suspected in order to avoid fatal complications.
The word trismus comes from the Greek word trismós meaning “gnashing.” Trismus is technically defined as a tetanic spasm of the jaw muscles, causing them to close rigidly. Restricted mouth opening (RMO) is a condition in which the mouth opening is restricted owing to any cause.
Sometimes, when wisdom teeth erupt in a poor position, they can cause lock jaw. Here's how: If the wisdom teeth are infected, they can cause swelling that limits the jaw's movement. The teeth my push on the jaw and keep it from moving properly.
Corticosteroid therapy is one of the means employed to reduce the postoperative sequelae of pain, swelling and trismus. The administration of corticosteroids in different dosage and through various routes has proven to be effective to control pain, inflammation, and trismus.
