MedlinePlus puts healing at 8 to 12 weeks for a typical break - set by your age, the bone, the type of break, and your health.
Children heal faster than adults, small bones faster than large. The cast bridges the break, the x-ray confirms it, and full strength trails weeks behind the x-ray - which is what follow-ups and physical therapy are for. Smoking measurably slows bone healing; early weight-bearing risks a crooked heal.

Common questions
How long does a broken bone take to heal?
MedlinePlus puts fracture healing at 8 to 12 weeks for a typical break, with the exact number set by your age, which bone broke, the type of break, and your general health - children heal noticeably faster than adults, small bones faster than large ones, and clean breaks faster than shattered ones. Understanding the phases keeps expectations sane: the cast or splint immobilizes the bone while the body bridges the break with new bone; the x-ray eventually shows the bridge; but full strength and full use trail the x-ray by weeks more, which is why follow-up visits and physical therapy exist rather than a simple cast-off celebration. Your inputs to the timeline: follow weight-bearing instructions exactly (early loading is how breaks shift and heal crooked), do not smoke (it measurably slows bone healing), eat protein and get calcium and vitamin D, and do the prescribed rehab. New worsening pain, numbness, or a cast that suddenly feels tight or smells wrong warrants a call. Pymander, a free AI doctor available 24/7 by text, can help you plan the recovery weeks.
