Chronic Orofacial Pain.
Dental Implications
Overview
Chronic Orofacial Pain (COFP) encompasses a range of persistent pain conditions that affect the face, mouth, and jaws, often without an identifiable cause. These conditions include
- myofascial pain,
- neuropathic pain,
- atypical facial pain,
- burning mouth syndrome.
COFP can be debilitating, leading to significant discomfort, emotional distress, and a reduced quality of life. The complex and multifactorial nature of COFP poses challenges in diagnosis and management, requiring a multidisciplinary approach that includes dental professionals, neurologists, and pain specialists.
Signs and Symptoms
Chronic Orofacial Pain can present with various signs and symptoms, which may include:
- Persistent pain in the face, jaws, or mouth, often described as aching, burning, or stabbing
- Pain that is not consistently linked to specific dental or medical conditions
- Muscle tenderness, particularly in the muscles of mastication
- Difficulty in chewing, speaking, or swallowing due to pain
- Psychological symptoms such as anxiety, depression, and sleep disturbances, often associated with chronic pain
These symptoms can significantly impact a patient's daily life and require careful management.
Diagnosis
Diagnosis of COFP involves a comprehensive evaluation to rule out other potential causes of orofacial pain and to identify the specific type of chronic pain disorder.
- Clinical Examination: Assessment of pain characteristics, including location, intensity, and duration, along with an evaluation of the muscles of mastication and jaw function.
- Patient History: Detailed history of the pain, including onset, triggers, and any associated symptoms such as stress or mood changes.
- Imaging and Diagnostic Tests: Imaging studies such as MRI or CT scans may be used to rule out structural abnormalities. Neurological tests may be necessary to assess nerve function if neuropathic pain is suspected.
Medical and Surgical Management
Management of Chronic Orofacial Pain requires a multidisciplinary approach that focuses on pain relief, improving function, and addressing psychological aspects of chronic pain.

Medical Management
Treatment for COFP typically involves a combination of pharmacological and non-pharmacological approaches, including:
- Medications: Analgesics, anticonvulsants, antidepressants, and muscle relaxants may be prescribed depending on the type of pain and its severity. Topical treatments such as capsaicin or lidocaine patches can also be used for localised pain relief.
- Physical Therapy: Exercises and stretches designed to improve muscle function and reduce pain in the jaw and face.
- Behavioural Therapy: Cognitive-behavioural therapy (CBT) and other psychological interventions can help patients manage the emotional and psychological aspects of chronic pain.
Surgical Interventions
Surgical interventions are generally considered a last resort for COFP, reserved for cases where conservative treatments have failed. Options may include:
- Nerve Block Injections: Injections of anaesthetic or steroid medications near nerves to provide temporary pain relief.
- Surgical Decompression: In cases of neuropathic pain, surgical decompression of the affected nerve may be considered to relieve pain.
Impact on Oral Health
Chronic Orofacial Pain has significant implications for oral health, particularly in how it affects a patient’s ability to perform regular oral hygiene and undergo dental procedures.
Pain-Induced Difficulty in Oral Hygiene
The persistent pain associated with COFP can make routine oral hygiene practices, such as brushing and flossing, difficult and uncomfortable.
This can lead to a decline in oral health, increasing the risk of dental caries and periodontal disease.
Impact on Eating and Nutrition
Patients with COFP may avoid certain foods or reduce their overall intake due to pain, leading to nutritional deficiencies that can further compromise oral health. This is especially concerning in conditions like burning mouth syndrome, where eating can exacerbate symptoms.
Psychological Effects and Oral Health
The psychological impact of chronic pain, including anxiety and depression, can negatively affect a patient's motivation to maintain oral health. Additionally, stress-related behaviours such as bruxism can exacerbate or contribute to COFP, leading to further complications.
Impact on Dental Treatment
Treating patients with Chronic Orofacial Pain requires a sensitive and individualised approach to minimise discomfort and address the complex nature of the condition.
Pre-Treatment Considerations
Before initiating any dental procedure, it is important to assess the patient’s pain levels, triggers, and any previous treatments they have received. Collaboration with the patient's pain management team or neurologist may be necessary to ensure a comprehensive approach.
Dental professionals should be aware of any medications the patient is taking that could affect treatment, such as anticonvulsants or antidepressants.
Appointment Timing and Management
Dental appointments should be scheduled at a time when the patient’s pain is well-managed. Shorter, more frequent appointments may be beneficial to minimise the stress and discomfort associated with prolonged dental procedures.
Pain management strategies, including the use of topical anaesthetics or conscious sedation, should be considered to reduce pain during treatment.
Infection Control and Use of Anaesthetics
Infection control is very important, particularly in patients with neuropathic pain or other conditions that may compromise their immune response. Local anaesthetics can generally be used safely, but care should be taken to avoid exacerbating pain during injections. In some cases, nerve block injections may be necessary to manage severe pain during dental procedures.
Post-Operative Care
Post-operative care for patients with COFP should focus on pain management and preventing exacerbations of their condition. Patients should be provided with detailed instructions on how to manage pain at home, including the use of prescribed medications and non-pharmacological strategies such as cold compresses or relaxation techniques.
Patient Education
Educating patients with Chronic Orofacial Pain about their condition and how to manage it effectively is very important for improving their quality of life and ensuring optimal oral health.
Patients should be encouraged to maintain gentle but thorough oral hygiene practices, even when experiencing pain. This may involve using a soft-bristled toothbrush, non-irritating toothpaste, and alcohol-free mouth rinses. Dental professionals should provide guidance on pain management strategies that can be used before and after oral hygiene practices to minimise discomfort.
Regular dental visits are essential for monitoring oral health and managing any issues that may arise due to COFP.
These visits also provide an opportunity to educate patients on the importance of maintaining oral hygiene despite the challenges posed by chronic pain.
Recognising Symptoms and Seeking Help
Patients should be educated on the signs of worsening COFP, such as increased pain intensity, changes in the nature of the pain, or new symptoms. They should be encouraged to seek help promptly if their pain becomes unmanageable, and to communicate openly with their dental and healthcare providers about their condition and any changes in their symptoms.
