Arthrocentesis Recovery
Flushing out an inflamed jaw joint. Here’s what the recovery week looks like.
The Full Guide
A minimally invasive procedure for the jaw joint (TMJ). Small needles are used to flush the joint space with sterile fluid, washing out inflammatory buildup and improving mobility, similar to flushing out a stiff, inflamed knee joint.
When a jaw joint is stiff and inflamed, arthrocentesis clears out the inflammatory buildup that's limiting movement and causing pain. A minimally invasive step that often significantly improves mobility before more involved surgical options would be considered.
Dealing with limited jaw mobility or persistent joint pain? Book a consultation and we'll talk through your options.
No special fasting required, though follow any specific instructions given if sedation is planned alongside.
Local anesthetic numbs the area near the ear and jaw joint, sometimes combined with light sedation.
Two small needles are placed into the joint space. Sterile fluid is flushed through the joint to clear out inflammatory debris, and the joint may be gently manipulated to improve range of motion before finishing.
Mild soreness, swelling, or bruising near the ear/jaw joint is common and expected. A small bandage is placed over the injection site and typically stays on for 1–2 days; a little blood on it is normal. You'll likely be sent home with an anti-inflammatory, an antibiotic, and an ear medication, since the joint sits right next to the ear canal.
Ice the area intermittently to reduce swelling. Keep your head elevated when resting, and avoid bending over, heavy lifting, or anything that raises pressure in your head. Showering and shampooing are fine starting the next day.
Stick to a soft diet for 2–6 weeks and avoid wide jaw movements (big bites, yawning wide, gum chewing), while the joint settles. Starting on day 3, gentle stretching exercises are typically recommended: opening as wide as comfortable and holding, repeated about 10 times, at least 10 times a day. Aim to fit about two fingers between your upper and lower teeth by the end of week 1, three fingers by week 2.
swelling worsens, you develop a fever, jaw mobility doesn't improve as expected, or bleeding continues after 10 minutes of firm thumb pressure on the site.
