Dentists treat trismus (jaw stiffness) by addressing the underlying cause, using medications (muscle relaxants, antibiotics if infected, NSAIDs for pain), physical therapy (stretches, heat, massage), and sometimes dental procedures or injections (like Botox) for severe cases, with the goal of restoring jaw movement through gentle exercises and managing symptoms.
There are 5 main ways to help manage trismus:
Your prognosis, or expected outcome, depends on the cause of the issue. For example, taking it easy on your jaw after wisdom tooth surgery is usually enough to fix trismus. It may take as little as a week to heal. Trismus after cancer treatment may cause symptoms for a long time.
Because lockjaw can quickly escalate in discomfort and severity, it's important to seek emergency or urgent dental care in Aberdeen, NC as soon as symptoms appear. Getting a prompt diagnosis and beginning treatment early can help restore comfort, prevent complications, and protect your overall oral health.
How a Dentist Treats Lockjaw
Trismus has a number of potential causes which range from simple and non-progressive to those that can be potentially life threatening. Knowledge of the normal range of mouth opening is essential in the diagnosis and treatment of trismus.
Jaw disorders, often referred to as temporomandibular joint (TMJ) disorders, affect the jaw joint and surrounding muscles. These conditions can cause pain, discomfort, and functional difficulties. Dentists play a crucial role in diagnosing and treating TMJ disorders.
The "Rule of 7" in dentistry is a pediatric guideline highlighting key milestones: a child should have their first dental visit by age 7, when their first permanent molars typically emerge and the first permanent teeth start to come in, prompting an orthodontic evaluation to catch early bite/crowding issues. It helps ensure early intervention for lifelong oral health, focusing on the transition from baby to permanent teeth around age 7, and even mentions seeing an orthodontist by 7 and evaluating wisdom teeth around 21.
Broken jaw as a complication of tooth extraction – check
Although rare, a broken jaw can be a complication of wisdom tooth extraction.
The 3-3-3 rule for toothache is a temporary pain management strategy: take 3 ibuprofen (200mg each) three times a day for 3 days, but 3 hours apart (or every 8 hours), to reduce inflammation and pain until you can see a dentist; it's crucial to consult a doctor first, especially with underlying conditions, as it's not a cure but a short-term fix for inflammation.
Exercise: Active and passive stretching/strengthening exercises to the muscles of mastication have been advocated by various authors in the treatment of trismus. As they work to stretch scar tissue, relax the muscle that are in spasm and increase muscle strengthen, bringing about increased range of motion of the TMJ.
After dental work, your jaw can tighten up, causing trismus or “lockjaw.” This condition triggers pain, muscle spasms, and difficulty opening your mouth fully. Trismus usually starts about two to three days after the procedure. It happens mainly at the treatment site. It should get better within about two weeks.
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.
Do not continue to exercise if the pain increases, or persists after exercising. Sugar free chewing gum may be helpful to keep your jaw moving.
This exercise gained wide popularity, but many dental professionals and orthodontists do not recommend it as it can adversely affect your bite. Another common technique is face yoga, which involves different exercises of the face, mouth, and jaw muscles for a more defined look.
Stretching Exercises
Relax your jaw, then with your teeth slightly apart, slowly open your mouth as wide as you can while looking up with your eyes. Hold your mouth open for a few seconds, then slowly close it. Once your mouth is closed, move your jaw to the left while looking to the left with your eyes.
Wisdom teeth top the list, followed by upper and lower molars and canine teeth. Factors like root structure, position, and bone density influence the difficulty of extraction. For children, retained baby teeth can also be challenging.
People with ONJ may experience pain, soft tissue swelling and drainage in the mouth, and an exposed jawbone for eight weeks or longer. Other possible signs are bad breath, loose teeth, and signs of infection of the gums.
Anxiety and panic can cause your jaw muscles to contract, making it difficult for your jaw to slide back into its proper position. Take a few deep breaths, close your eyes, and remember that if you're unable to unlock your jaw on your own, your TMJ dentist can help you.
Code 0 – Healthy gums, no bleeding when probed, no calculus or gingival pockets under 3.5mm. Code 1 – Slight bleeding when probed, no calculus or gingival pockets under 3.5mm. Code 2 – Slight bleeding when probed, Calculus or Plaque present and gingival pockets under 3.5mm.
Four-handed dentistry is the practice of combining the dentist's two hands with the two hands of the dental assistant. The results are more efficient, speedy, and consistent patient care—and a happier dental practice.
The 2-2-2 rule in dentistry is a simple guideline for good oral hygiene: brush twice a day, for two minutes each time, and visit your dentist twice a year, helping to prevent cavities, gum disease, and other dental problems by establishing consistent habits for plaque removal and professional monitoring.
Symptom-directed interventions, including heat therapy, analgesics such as non-steroidal anti-inflammatories (NSAIDs), and muscle relaxants, are usually prescribed in the acute phase and are the mainstays for treating uncomplicated transient trismus.
In some severe cases, your dental professional may recommend orthognathic surgery of your jaw. This procedure involves adjusting or repositioning your upper or lower jaw and is often used in combination with orthodontic correction like braces.
Take Jaw Pain Seriously: Call for a Dental Emergency
Jaw pain and lockjaw can be signs of a deeper issue like TMJ or a dental infection. If you're struggling to chew, speak, or open your mouth fully, it could be a dental emergency that needs quick attention.
