how long does it take for a broken jaw to heal

Most broken jaws take about 4–8 weeks for the bone to knit enough to function, but full recovery of strength and normal chewing can take 3–6 months depending on how severe the fracture is and whether surgery is needed. Mild, non‑displaced fractures can heal near the 4–6 week mark, while complex fractures that require plates, screws, or wiring often sit at the longer end of that range or beyond.

Typical healing timeline

• Mild or hairline fracture (no displacement): bone healing usually in about 4–6 weeks with conservative treatment like rest, soft or liquid foods, and pain control.

• Moderate to severe fracture (with displacement, often needs surgery): initial bone healing commonly 6–12 weeks, with overall recovery (strength, chewing, opening) often stretching to 3–6 months.

• Multiple or complex fractures: may take several months and need closer follow‑up and sometimes physiotherapy to restore full jaw function.

What affects how fast it heals

• Severity of the break : Simple cracks heal faster than displaced or shattered segments fixed with plates and screws.

• Treatment type: Non‑surgical immobilization tends to have shorter bone‑healing times than cases needing open surgery, wiring, or hardware.

• Your age and health: Smoking, poor nutrition, diabetes, or poor oral hygiene can slow bone healing and raise infection risk.

• How well instructions are followed: Sticking to liquid/soft diets, not chewing hard foods, taking medications as prescribed, and going to follow‑ups strongly influences outcome.

What recovery feels like, week by week (rough guide)

• First days: Swelling, bruising, and significant pain; usually liquid diet and very limited jaw movement, especially if wired or banded.

• Weeks 1–4: Bone starts to knit; wiring or elastics often stay in; most people remain on liquids or very soft foods; pain and swelling gradually ease.

• Weeks 4–8: Many simple fractures are largely healed; diet can often progress to soft then more regular foods as cleared by the surgeon or dentist.

• After 8–12 weeks: Most daily activities and normal diet resume, though stiffness, mild soreness, or weakness when chewing tough foods can linger.

• Up to 3–6 months: Jaw strength, bite, and opening usually return closer to baseline; complex cases may still be under review or doing exercises.

When to seek urgent help

• Trouble breathing, severe bleeding from the mouth, or inability to close the mouth properly.
• New or worsening numbness of the chin or lips, fever, foul taste, or increasing pain and swelling, which can signal infection or healing problems.

Anyone with a suspected broken jaw should be seen urgently in an emergency or oral–maxillofacial setting, and only a clinician who has reviewed imaging can give a personalized estimate of how long that specific jaw will take to heal.
