Common Causes for Mouth Clicking Noises in Seniors
The most frequent reason for clicking or popping sounds from the mouth is an issue with the temporomandibular joint (TMJ), which connects the jawbone to the skull. The intricate movements of this joint, essential for talking and eating, can be disrupted by several age-related factors.
Temporomandibular Joint (TMJ) Disorder
TMD, or temporomandibular disorder, is a common cause of persistent jaw noises. It occurs when the cartilage disc that cushions the jaw joint shifts or becomes displaced. As the disc snaps in and out of position during jaw movement, it can create a clicking or popping sound. Factors contributing to TMD in older adults include:
- Bruxism: Habitual teeth grinding or clenching puts excessive stress on the TMJ and is a common culprit behind jaw clicking, particularly during sleep.
- Arthritis: Degenerative joint diseases like osteoarthritis and rheumatoid arthritis can affect the TMJ, causing inflammation and cartilage wear-down over time.
- Muscle Strain: Tension from stress, anxiety, or overuse can cause jaw muscle strain, leading to sounds and discomfort.
- Previous Injury: A past injury or trauma to the jaw can cause misalignment and long-term issues.
Dental Health Issues
Oral health problems are another significant source of mouth noises in the senior population. Regular dental check-ups are crucial for catching these issues early.
- Ill-fitting Dentures: For those with dentures, a poor fit can cause them to move or shift while eating or talking, resulting in a smacking or clicking sound. This can also cause irritation and discomfort over time.
- Misaligned Bite (Malocclusion): As teeth wear down or are lost, bite alignment can change. A misaligned bite places uneven pressure on the jaw, which can cause TMJ issues and clicking.
- Missing Teeth: Chewing on one side to compensate for missing teeth can strain the TMJ, leading to clicking and popping sounds.
Dry Mouth (Xerostomia)
Dry mouth, or xerostomia, is not a normal part of aging but is common among seniors due to various factors, including medication side effects and health conditions.
- Reduced Saliva: A lack of saliva means there is less lubrication in the mouth. This can cause dentures to slip or the mouth tissues to stick and release, creating a clicking or smacking noise.
- Medication Side Effects: Many common prescription medications for high blood pressure, depression, and other conditions can decrease saliva production.
- Dehydration: Seniors may have a reduced sense of thirst, leading to dehydration, which directly impacts saliva levels.
Neurological and Medical Conditions
In some cases, involuntary mouth movements are a symptom of a neurological or medical condition, particularly in advanced age.
- Tardive Dyskinesia: This neurological condition is a side effect of long-term use of certain medications, such as antipsychotics. It causes involuntary, repetitive movements, including lip-smacking, grimacing, and other mouth movements.
- Dementia and Cognitive Changes: Conditions like dementia can lead to involuntary chewing motions, sometimes called 'phantom chewing,' or perseveration, where a person repeats a gesture or movement.
- Palatal Myoclonus: This rare movement disorder involves rhythmic contractions of the soft palate at the back of the mouth, which can cause an audible clicking sound.
Comparison of Common Causes
| Feature | TMJ Disorder | Ill-Fitting Dentures | Dry Mouth | Tardive Dyskinesia |
|---|---|---|---|---|
| Symptom Type | Clicking/popping sound from the joint, often with pain or stiffness. | Smacking or clicking sound from dentures slipping. | Sticky sensation, difficulty swallowing, mouth noises from lack of lubrication. | Involuntary, repetitive mouth movements and smacking. |
| Trigger | Chewing, yawning, speaking, or stress. | Chewing, talking, or movement of the mouth. | Dehydration, medication, or medical conditions. | Long-term use of specific antipsychotic medications. |
| Associated Symptoms | Jaw pain, headaches, earaches, limited jaw movement. | Sore gums, trouble eating, discomfort. | Tooth decay, fungal infections, sore throat. | Grimacing, eye-blinking, involuntary limb movements. |
| Treatment Focus | Jaw exercises, stress management, splints, medication. | Dental adjustment or replacement of dentures. | Hydration, saliva substitutes, medication review. | Medication review, Botox injections, or other therapies. |
Treatment and Management
Management depends on the underlying cause. For minor issues, simple home care can help, while more severe problems require professional intervention.
Home Remedies
- Rest the Jaw: Avoid hard or chewy foods and extreme jaw movements like wide yawning to reduce strain.
- Moist Heat or Ice: Applying warm, moist heat or ice packs can help soothe jaw pain and inflammation associated with TMJ disorders.
- Stress Management: Since stress and anxiety often lead to clenching, relaxation techniques like meditation or gentle jaw exercises can be beneficial.
- Hydration: For dry mouth, sipping water frequently and using a humidifier can help.
- Sugar-Free Gum: Chewing sugar-free gum or lozenges can stimulate saliva production.
Professional Treatments
- Dental Assessment: A dentist can check denture fit, assess for malocclusion, and recommend adjustments or new prostheses if needed.
- Physical Therapy: Specialized physical therapy, including jaw exercises, can help improve TMJ function.
- Oral Appliances: Custom-made mouthguards or splints can protect teeth from grinding and help realign the jaw.
- Medication Review: A doctor can review medications causing dry mouth or other neurological symptoms and explore alternative treatments.
- For Neurological Issues: Conditions like tardive dyskinesia require specialized neurological care. Management might involve medication adjustments or other treatments.
Seeking Professional Help
While occasional jaw noises are not always cause for concern, persistent clicking, pain, or other symptoms warrant a professional evaluation. Ignoring these issues can lead to permanent joint damage. If you or a loved one is experiencing persistent mouth clicking, consulting a dental care provider is the best course of action. A skilled TMJ dentist can diagnose the underlying issue and formulate an effective treatment plan. For issues potentially related to medication or neurological conditions, a physician or neurologist should be consulted.

Conclusion
Mouth clicking in older adults can have various causes, ranging from simple issues like ill-fitting dentures or dry mouth to more complex conditions like temporomandibular joint (TMJ) disorders or medication side effects. While not always a sign of a serious problem, persistent or painful clicking should be evaluated by a healthcare professional. Proper diagnosis is the first step toward effective management, which can involve dental adjustments, jaw exercises, stress reduction, or medication review. Addressing these issues ensures better oral health, comfort, and overall well-being in the aging process.
