How to Stop Your Voice from Getting Stuck in the Mouth

Stuck Mouth: Overcoming Jaw Tightness for Clear Speech

Understanding the Two Mouths and the Jaw Joint in Singing

Getting a stuck mouth is an all too common vocal issue, leading to jaw tightness and even jaw pain for many singers.

One way to get stuck is to get stuck in the mouth. Well, this might seem to be a totally incoherent statement. Doesn't the singer's sound come out of the mouth? Yes, it does. However, in functional voice training, it could be said that there are two mouths.

What?!

The “first mouth” includes the lips, teeth, tongue, jaw, and jaw muscles, basically, the structure you see and use for finishing touches on vowels and consonants. This mouth is for clear diction and articulation. But problems arise when the sound gets stuck here, often resulting in mismatched pitch and vowel, trouble singing higher notes, and unclear diction. Jaw stiffness and muscle tension can make these symptoms worse, leading to difficulty opening your mouth and pain during singing.

For a deeper explanation of this concept, see Stuck In Mouth, which explains how the first mouth and the “real” mouth of the singer work together during singing.

Okay, so what about the second mouth? The “real” mouth of the singer is the oropharynx, the area at the back of the mouth, above the larynx and surrounding muscles. Here, the vocal cords respond to musical stimuli to produce pitch and also help shape the vowel sound. In healthy singing, as you move to higher pitches, the vowel and pitch match perfectly, and you feel the sound traveling back and up into your head, like walking up a staircase backward.

If the vowel is too big for the pitch step, you end up “stuck” under the hard palate in the first mouth. This is when singing higher becomes a struggle, often leading to forced, strained singing and poor diction. But when the pitch and vowel are balanced, the “vibrating column of air” rises, moves back toward the soft palate, and into the sinus cavities, letting the first mouth be free for finishing touches. This is the opposite of getting stuck!

Understanding how vowels are formed in the real mouth of the singer can help clarify why vowel shape and pitch coordination matter when singers move through their range.

Transitioning from Singing Concepts to Jaw Health:

Just as singers need freedom of movement in both “mouths” for healthy vocal production, overall jaw health, and by extension, healthy speech and singing, requires that the jaw joint, jaw muscles, and surrounding muscles be free from jaw stiffness, jaw pain, muscle spasms, and jaw locks. Let’s look at what can go wrong with the jaw and how you can care for it.

Common Causes of Jaw Locks and Locked Jaw Issues

Jaw pain and related problems are widespread and can have various root causes. One of the most common conditions is temporomandibular disorder (TMD) or temporomandibular joint disorder (TMJ disorder), a dysfunction or inflammation of the jaw joint (also called temporomandibular joints or TMJ) and surrounding muscles. This joint is cushioned by cartilage and allows for smooth jaw movement.

Many factors contribute to TMD, including:

• Muscle spasms: Overuse or tension in the jaw muscles can cause jaw pain, jaw tightness, and muscle spasms that make it hard to open your mouth fully or close your mouth completely. Trismus, commonly known as lockjaw, occurs when jaw muscles spasm or joint components malfunction, severely restricting the ability to open or close the mouth fully.
• Teeth grinding (bruxism): Chronic clenching or grinding puts excess strain on the jaw joint and can lead to jaw injury and scar tissue formation. Teeth grinding, also known as bruxism, is a common problem that can lead to TMD, tightness and soreness in the jaw, and may contribute to jaw locking.
• Jaw injury: Trauma to the jaw bone or surrounding cartilage leads to persistent pain, inflammation, and sometimes a locked jaw. Jaw locking can be a result of muscle spasms, trauma, or inflammation and is commonly described as a scary experience that impacts daily activities such as eating and speaking.
• Rheumatoid arthritis: This autoimmune disease not only affects other joints but can also cause joint pain, jaw tightness, cartilage damage, and even deformity of the jaw joint, contributing to TMD. Osteoarthritis may also damage cartilage and bone within the TMJ.
• Stress, anxiety, and muscle tension: Stress can contribute to TMD by causing individuals to clench their jaws or grind their teeth. Both physical and psychological stress are closely linked to muscle strain and tension-related symptoms.
• Certain medications or cancer treatment: Side effects from cancer treatment, such as radiation or chemotherapy, and certain medications can lead to jaw stiffness, dry mouth, trismus, and difficulty opening your mouth.
• Dental factors: Trismus can result from dental procedures, inflammation, or infections.

Additional causes of trismus include anxiety, bruxism, trauma, and inflammation. Gentle movement, diet management, and heat application can help alleviate symptoms of trismus.

A common symptom of these problems is difficulty opening the mouth, difficulty chewing, or feeling discomfort while eating and talking. Sometimes, the jaw may lock in a closed position (called "closed lock"), making it impossible to open your mouth wide. In other cases, an "open lock" can occur, leaving you unable to close your mouth properly. Both may be accompanied by a clicking sound, popping, or grating sensation in the joint. Inflammation in the jaw area can limit movement and contribute to TMD symptoms.

About Globus Sensation and Related Jaw/Throat Issues

Globus sensation refers to the feeling of a lump in the throat without a physical blockage. Common causes include stress, anxiety, acid reflux, and muscle tension. Acid reflux can irritate the throat lining and lead to globus sensation. Treatment for globus sensation may involve stress management techniques and dietary adjustments. Seek medical help if globus sensation is accompanied by pain, difficulty swallowing, or unexplained weight loss.

Signs, Symptoms, and Jaw Tightness to Watch For

Jaw issues can range from mild to severe cases and may involve:

• Jaw pain or tenderness (especially near the ear, lower jaw, neck, or jaw joint)
• Tight jaw muscles and jaw stiffness
• Clicking sound, popping, or grinding in the jaw joint during jaw movement (such as when you chew gum, eat, or talk)
• Muscle spasms in the jaw, neck, or surrounding muscles
• Swelling or pain along the jaw bone
• Joint pain in other joints in addition to the jaw joint
• Severe headaches, earaches, or facial pain
• Locked jaw (either open lock or closed lock)
• Difficulty swallowing, difficulty eating, or trouble opening your mouth (sometimes caused by scar tissue or jaw injury)
• Chronic orofacial pain, which may require professional treatment
• Symptoms that interfere with chewing, speaking, or daily activities

TMD symptoms may include pain, limited jaw movement, and muscle stiffness. Jaw tightness may cause pain or discomfort that could affect daily activities, such as eating and drinking.

When to See a Specialist: Warning Signs and Difficulty Opening Your Mouth

See a healthcare professional or an orofacial pain specialist promptly if you experience any of the following:

• Persistent jaw pain or jaw tightness that doesn't improve with home remedies
• Severe headaches, facial pain, or jaw pain that radiates to the neck or other joints
• Inability to open your mouth (closed lock) or trouble closing it (open lock)
• Difficulty swallowing, speaking, or breathing
• Signs of a serious bacterial infection (fever, swelling, red skin)
• Jaw pain after a jaw injury or accident
• Pain accompanied by chest pain, potentially a sign of another medical emergency
• Difficulty chewing, severe jaw stiffness, or pain during cancer treatment
• Locking of the jaw following an injury, high fever, or if swallowing or breathing is impossible should be treated as a medical emergency.
• If jaw locking persists, it is important to seek professional help for evaluation and treatment.

Practical Self-Care, Moist Heat, and Home Remedies for Jaw Pain

Many mild jaw issues can be managed with jaw exercises, home remedies, and simple changes in daily habits to prevent further damage and promote healing.

Home Remedies for Jaw Pain and Locked Jaw

• Apply moist heat or a warm compress: Placing a warm, moist cloth or heating pad on the jaw joint can help relieve muscle spasms and relax tight jaw muscles.
• Ice pack: Use an ice pack on the jaw for 10–15 minutes to ease swelling or pain after injury.
• Soft foods: Stick to soft foods that don’t require much chewing (like yogurt, mashed potatoes, scrambled eggs) when you feel discomfort, have jaw pain, or difficulty opening your mouth.
• Avoid chewing gum and hard foods: Chewing gum or hard foods like tough meats and raw vegetables may further irritate the jaw joint and surrounding muscles.
• Gentle jaw movements: Slowly open and close your mouth several times, then gently move your jaw left and right to keep the joint and muscles flexible.
• Jaw joint stretches: Place your tongue on the roof of your mouth, then slowly open your mouth as wide as you comfortably can without pain, and hold for a few seconds. Repeat a few times daily.
• Manual jaw-opening exercise: Use your fingers to gently apply gentle pressure to the front of your chin or lower jaw, slowly opening your mouth to gently stretch the joint and muscles, and then relax.
• Smile stretch: Form your widest smile without pain, then slowly open your mouth about two inches while still smiling. Take a breath, exhale, and slowly close your mouth. Repeat several times.
• Stress reduction: Since stress and muscle tension can increase jaw pain, try deep breathing, meditation, gentle neck stretches, or even physical therapy.
• Pain relievers: Over-the-counter pain relievers like ibuprofen may help with mild jaw pain.

If these measures don’t improve your symptoms, consult a healthcare professional for other treatment options such as prescription medications, physical therapy, or professional treatment.

Treatment for TMD may include non-invasive therapies, medications, and in some cases, surgery. Treatment for trismus focuses on relaxing the muscles and addressing the underlying cause.

Understanding Medical Terms and When to See an Orofacial Pain Specialist

• Temporomandibular Joint Disorder (TMD/TMJ disorder): TMD or TMJ disorder is a condition affecting the temporomandibular joints, the hinges connecting your jaw to your skull. Symptoms include jaw pain, joint pain, muscle spasms, a clicking sound, and difficulty opening or closing your mouth.
• Muscle spasms: Sudden, involuntary contractions of the jaw muscles, leading to pain and jaw tightness.
• Closed lock: A type of locked jaw where your mouth gets stuck in a closed position and you can't open it.
• Open lock: The jaw locks in a partially open position, making it hard to close your mouth fully.
• Cartilage: Smooth, flexible tissue covering the ends of bones in the jaw joint.
• Orofacial pain specialist: A professional trained to diagnose and treat TMJ disorder and related jaw problems.
• Serious bacterial infection: Such as occurs after an untreated dental abscess, can cause swelling, severe pain, and affect jaw movement.

When Jaw Pain Needs Prompt Professional Treatment

While many cases can be managed with home remedies, mild medications, and gentle care, jaw issues can sometimes point to more significant problems. These may include a serious bacterial infection, untreated TMJ disorder, rheumatoid arthritis, or effects from cancer treatment. Early treatment is crucial to avoid further damage and complications.

If your symptoms persist, grow worse, or match any of the listed warning signs, consult a dentist, doctor, or orofacial pain specialist to discuss diagnosis and treatment. They may recommend advanced treatment options, such as physical therapy, prescription medications, or even surgery for severe cases.
