Dental arthritis: symptoms, causes and solutions to relieve pain

Jaw pain that lingers for a while and worsens when talking or eating is never something to take lightly. If you're experiencing this discomfort, it could well be dental arthritis .

Little known to the general public, it affects the temporomandibular joint (TMJ ) and can really hinder daily life, whether it's eating or even speaking clearly. We explain everything in this article!

Dental arthritis is actually an inflammation of the joint that connects your jaw to your skull. As with other types of arthritis, the cartilage gradually wears away, which can cause pain, a feeling of locking, and sometimes swelling. 

The key point to remember is that this problem often occurs when you already suffer from other forms of arthritis , such as rheumatoid arthritis or psoriatic arthritis.

Dental arthritis doesn't originate directly from the teeth themselves, but from the joint that moves them. While a cavity or an abscess will cause pain in a specific tooth, here the pain is located around the jaw , near the ear, and it worsens when you open or close your mouth.

Sometimes, diseases like rheumatoid arthritis, lupus, or ankylosing spondylitis attack the temporomandibular joint. The inflammation, already present in the body, eventually spreads to the TMJ, resulting in persistent pain and a feeling of locking.

In some cases, the infection reaches the periodontal ligament, the connective tissue surrounding the root of the tooth, creating a point of inflammation close to the joint.

A sharp blow to the gums, a fall, or even opening the mouth too abruptly can be enough to trigger inflammation . Over time, these repeated micro-traumas eventually wear down the joint and cause arthritis in the tooth.

Bruxism (involuntary teeth grinding, often at night) or poor neck posture puts the jaw under constant tension. This excessive pressure, day after day, eventually irritates the joint and triggers a condition.

A neglected cavity in a tooth, an abscess , or even an illness like otitis can sometimes affect the neighboring joint. In this case, it's called infectious arthritis , a condition that requires prompt treatment to prevent it from worsening.

Pain remains the most common symptom. It is usually located near the ear, right where the jaw articulates. But that's not all:

• The joint may be swollen and warm to the touch.

• A morning stiffness that fades as the day progresses,

• Cracking or clicking noises when opening the mouth,

• Sometimes even a slight asymmetry of the face.

It's true that dental arthritis can complicate daily life. Chewing, speaking, or even yawning can sometimes become painful . In more advanced cases, it can be difficult to open the mouth fully. Some patients also experience pain radiating to the temples, teeth, or neck, which can make diagnosis difficult.

Some patients also experience pain radiating to the temples, teeth, or neck, which can make diagnosis difficult.

During the consultation, the dentist or oral surgeon begins by asking you detailed questions about your symptoms: when the pain appears, its intensity, its type, etc. Then, they examine your jaw by palpating the joint, observing how you open and close your mouth, and looking for any clicking or popping sounds, difficulty opening your mouth wide, or local swelling.

In some cases, the specialist may request images of the joint (panoramic X-ray, CT scan, or MRI) to more precisely visualize the condition of the cartilage. Blood tests are sometimes necessary to check for inflammation or infection. By combining all this information, the practitioner can confirm the diagnosis and propose the most appropriate treatment.

Your doctor will usually prescribe anti-inflammatory or pain-relieving medication to relieve your symptoms. If an infection is the cause, they may also prescribe appropriate antibiotics. When dental arthritis is linked to a condition like rheumatoid arthritis, a rheumatologist often takes over to adjust the treatment. In some cases, cortisone injections directly into the joint can also provide significant relief.

Mandibular physiotherapy or osteopathy can work wonders to restore mobility and relax the muscles of the mouth. Applying a cold pack to the painful area is also very effective in reducing inflammation. Sometimes, an occlusal assessment is necessary to rebalance your bite and relieve tension in the joint.

Fortunately, surgery is rarely necessary. It is only considered when all other treatments have failed. Depending on the situation, this can range from a simple arthroscopy to clean the joint to a more complex reconstruction in the most severe cases.

Alongside medical follow-up, here are some tips that can help reduce pain and inflammation.

• Applying cold : Apply an ice pack wrapped in a cloth for 10 to 15 minutes, several times a day. This effectively calms inflammation and reduces pain.

• Anti-inflammatory diet : favor oily fish, red berries, and nuts. Also reduce your intake of processed foods that are too sugary or fatty.

• Joint rest : avoid hard foods, long conversations and excessive yawning.

• Relaxation and stress management : if you grind your teeth at night because of stress, simple techniques like breathing exercises or a little sophrology can help.

Taking care of your gums and dental health also contributes to prevention: a healthy mouth reduces the risk of chronic inflammation and associated joint diseases. Of course, this advice is not a substitute for your doctor's opinion, but it can help you live better every day.

Preventing dental arthritis starts with good oral hygiene and paying close attention to your posture and habits. Here are a few simple tips to put into practice:

• Don't wait until you're in pain to see your dentist ; regular checkups allow for the early detection of minor imbalances.

• In cases of bruxism , a mouthguard can help you relax and protect your joints.

• Pay attention to your posture, especially in the neck and shoulders, which are often responsible for jaw tension.

• Never let a dental or ENT infection linger .

• Adopt a balanced diet that limits inflammation.

These reflexes will help you preserve your jaw joints and avoid many persistent ailments.

Patients suffering from dental arthritis who share their experience often tell us how much their daily lives have improved after a clear diagnosis and personalized follow-up.

Thanks to an approach combining medical care, gentle oral exercises and some adjustments to their habits, such as wearing a mouthguard at night, they have regained real long-term comfort.

Many also emphasize the importance of being accompanied by several professionals: dentist, physiotherapist, and sometimes even rheumatologist, who work together for comprehensive care.

According to a recent meta-analysis published in 2024 in the Journal of Clinical Medicine , temporomandibular joint problems affect between 30 and 35% of the world's population.

Among these patients, approximately 6 to 9% suffer from chronic pain requiring regular medical monitoring , as reported by Univadis France in 2024. And when we look more specifically at patients with inflammatory diseases such as rheumatoid arthritis, the situation is even more pronounced: the temporomandibular joint is affected in 17 to 20% of cases , according to the Journal of Oral & Facial Pain and Headache .

The key takeaway is that while temporomandibular joint arthritis remains relatively rare, it is still a significant cause of oral pain. It's a health issue that shouldn't be underestimated.
