How Long Does Bell’s Palsy Last? Recovery Timeline
By Butler Family Health Center · Published 2026-09-16 · Last updated 2026-09-16
Most people with Bell’s palsy see improvement within 2 to 3 weeks and full recovery within 3 to 6 months. How long does Bell’s palsy last? Recovery timeline depends on how severe the nerve damage is and how quickly treatment begins. About 70 percent of people recover completely, with no lasting weakness. Mild cases often show noticeable progress in the first 2 to 3 weeks. Moderate cases take up to 4 to 6 months for most function to return. Severe cases involving complete facial paralysis at onset can take 9 to 12 months. A small number of people, roughly 5 to 10 percent, are left with mild lasting weakness. Full paralysis that never improves at all is rare.
What Is Bell’s Palsy?
Bell’s palsy is sudden, temporary weakness or paralysis on one side of the face caused by inflammation of the facial nerve. The facial nerve, known medically as cranial nerve VII, controls the muscles you use for blinking, smiling, and chewing. When that nerve becomes inflamed, it swells inside a narrow bony canal in the skull, compressing the nerve and cutting off normal signals to the muscles on one side of the face.
Symptoms appear fast. Most people notice changes overnight or within 48 hours. The face on one side may droop, and the eye on that side may not close fully. Other signs include drooling, difficulty chewing, and dryness in the affected eye.
Bell’s palsy is not a stroke. Stroke weakness usually affects an arm or leg as well, while Bell’s palsy affects only the face. It’s not dangerous in most cases, though the eye needs careful protection during recovery. We see patients come in who didn’t realize the eye was the urgent part, so that’s worth saying plainly up front.
What Causes Bell’s Palsy?
Viral infections are the most common trigger for Bell’s palsy. The herpes simplex virus, the same virus that causes cold sores, is the most frequently identified cause. Other viruses linked to Bell’s palsy include varicella-zoster (chickenpox), Epstein-Barr, and cytomegalovirus. The infection is thought to reactivate and inflame the facial nerve.
Who Gets Bell’s Palsy?
Bell’s palsy can affect any age group. Pregnancy, especially in the third trimester, raises the risk. Diabetes and upper respiratory infections also increase a person’s likelihood of developing it. People with a family history of Bell’s palsy face a slightly elevated risk as well.
Common symptoms include one-sided facial drooping or weakness, inability to fully close the eye on the affected side, drooling or difficulty eating and drinking, and reduced ability to taste or increased sensitivity to sound on the affected side.
How Long Does Bell’s Palsy Last for Most People?
For most people, Bell’s palsy lasts between 2 weeks and 6 months from first symptoms to full recovery. Where you fall in that range depends largely on how severe the nerve involvement was at the start.

Research cited by the National Institute of Neurological Disorders and Stroke shows that roughly 70 percent of untreated people recover fully. Starting treatment early raises that number. Age also plays a role. Younger people tend to recover faster and more completely than older adults.
Does Bell’s Palsy Go Away on Its Own?
Yes, Bell’s palsy does resolve on its own in most cases. The facial nerve has a strong ability to heal without intervention. That said, medical treatment with corticosteroids shortens recovery time and improves the odds of complete healing. Waiting it out without any care means accepting a slower timeline and a slightly lower chance of full recovery. We’d rather you not wait.
Mild cases with only partial weakness have the best outlook with or without treatment. Severe cases with complete paralysis at onset benefit the most from prompt medical attention.
What Are the Stages of Bell’s Palsy Recovery?
Bell’s palsy recovery moves through four general stages: onset, acute inflammation, early nerve healing, and full muscle reactivation. Understanding each stage helps set realistic expectations for what to watch for week by week.
- Stage 1 (Days 1 to 3): Onset and peak inflammation. Symptoms appear and may continue to worsen during these first days. This is when the nerve is most compressed and inflamed. Pain behind the ear on the affected side is common at this stage.
- Stage 2 (Days 4 to 14): Stabilization. Visible symptoms aren’t improving yet, but the inflammation begins to settle. The nerve is stabilizing. Starting corticosteroids during Stage 1 or early Stage 2 has the greatest effect on outcomes.
- Stage 3 (Weeks 2 to 8): Early movement returns. Small signs of recovery begin to appear. You may notice a slight ability to close the eye partway, or a small lift at the corner of your mouth. Those small movements mean nerve signals are getting through again, and they matter.
- Stage 4 (Months 2 to 6): Strength and coordination return. Most people reach normal or near-normal facial function during this stage. Movements become stronger and more controlled, and coordination between muscle groups improves steadily.
A small group of people move into a prolonged recovery phase where synkinesis can develop.
What Is Synkinesis in Bell’s Palsy?
Synkinesis is when two facial muscles move together unintentionally during recovery. For example, your eye may close slightly when you smile. This happens because the nerve fibers regenerate along incorrect pathways. It’s not dangerous, but it can be socially uncomfortable and may require targeted physical therapy to manage.
What Speeds Up Bell’s Palsy Recovery?
Starting corticosteroids like prednisone within 72 hours of symptoms is the strongest evidence-based way to speed Bell’s palsy recovery. The sooner you see a doctor after symptoms appear, the more effective steroid treatment tends to be. Most people don’t realize how tight that 72-hour window is until after the fact, so if you’re reading this early, go now.
Corticosteroids reduce nerve inflammation and improve the odds of complete recovery. Research supports early steroid use as improving outcomes compared to no treatment. Some doctors also prescribe antiviral medications alongside steroids, particularly when a viral trigger is suspected.
Eye care is non-negotiable. The eye on the affected side may not close fully, leaving the cornea exposed. Lubricating eye drops during the day and a protective eye patch at night prevent corneal damage while the nerve heals.
Do Facial Exercises Help Bell’s Palsy?
Yes, gentle targeted facial exercises begun during the early healing stage help rebuild muscle coordination. A physical therapist trained in facial rehabilitation can guide these exercises. Going hard or forcing movement too early can reinforce poor patterns rather than fix them. Let a professional pace it with you.
Can Heat or Massage Help Bell’s Palsy?
Warm compresses applied to the affected side can ease discomfort and muscle stiffness. Gentle massage of the face may also provide relief. Both approaches support comfort but don’t replace medical treatment or supervised facial rehabilitation.
The short version of what you should be doing: see a doctor within 72 hours of first symptoms to start corticosteroids, use lubricating eye drops during the day and patch the eye at night, begin gentle facial exercises under professional guidance once healing starts, apply warm compresses to ease stiffness, and prioritize sleep and reduce physical stress on your body during recovery.
When Does Bell’s Palsy Become Permanent?
Bell’s palsy is considered permanent or long-term when significant weakness remains after 12 months with no further improvement. Most meaningful recovery happens within the first 6 months. Progress that hasn’t appeared by the 12-month mark is unlikely to come.
About 5 to 10 percent of people are left with some lasting facial weakness or asymmetry. Several factors raise the risk of incomplete recovery: complete paralysis at the time symptoms first appeared, no visible improvement in the first 3 weeks of onset, delayed start to medical treatment, older age at the time of the episode, and presence of diabetes or high blood pressure.
Even among people with lasting effects, symptoms are often mild. A slight droop at rest or difficulty with fast facial expressions is more common than severe permanent paralysis.
How Do Doctors Know If Nerve Damage Is Severe?
Electromyography (EMG) testing and nerve conduction studies measure how much of the facial nerve is still functioning. EMG records the electrical activity inside the facial muscles and shows whether nerve signals are reaching those muscles. Doctors may use repeat EMG testing during recovery to get a clearer picture of long-term outlook. A larger drop in nerve signal strength suggests a longer recovery ahead.
Can Bell’s Palsy Come Back After It Heals?
Yes, Bell’s palsy can recur, though this happens in fewer than 10 percent of people who have had it. Recurrence can happen on the same side of the face or the opposite side. Each new episode follows its own course and doesn’t always mirror the severity of the first.
When Bell’s palsy recurs, doctors typically investigate more thoroughly to rule out other conditions. Tumors affecting the facial nerve, autoimmune diseases, and Lyme disease can all produce facial weakness that looks like Bell’s palsy. A second or third episode raises enough concern to warrant specialist evaluation.
Keeping underlying health conditions well managed may help protect nerve health. Diabetes and high blood pressure both affect nerve health, and poor control of either condition can make the facial nerve more vulnerable. If Bell’s palsy returns more than once, a referral to a neurologist or ear, nose, and throat specialist is strongly recommended. We’d be direct with any patient about that. Getting a thorough workup on a second episode isn’t optional in our view.
Can a Chiropractor Help With Bell’s Palsy Recovery?
Some people in Centennial, CO seek chiropractic care as a supportive therapy during Bell’s palsy recovery. The focus is typically on cervical spine alignment and supporting the nervous system’s ability to function without added interference.
The facial nerve originates from the brainstem, which sits at the junction of the skull and the upper cervical spine. Some chiropractors work in the upper cervical region to address joint restriction in that area. We’re not claiming to treat Bell’s palsy directly. What we can do is clear mechanical interference in the upper neck and give the nervous system a cleaner environment to heal in.
Chiropractic care doesn’t replace first-line medical treatment like corticosteroids. It’s used alongside conventional care, not instead of it. Patients who also have neck stiffness, tension headaches, or restricted cervical movement alongside Bell’s palsy may find that addressing those issues makes other rehabilitation activities easier to perform. For those in Centennial, CO seeking supportive care during Bell’s palsy recovery, chiropractic care in Centennial, CO is available locally.
Always tell your primary care doctor or neurologist about any additional therapies you’re pursuing. We welcome that kind of coordination. It leads to better outcomes for you, and that’s the whole point.
What Should I Ask a Chiropractor About Bell’s Palsy?
Ask whether the chiropractor has experience working with neurological cases. Ask specifically about upper cervical techniques and how those differ from standard spinal adjustments. Ask how the chiropractor plans to coordinate with your medical team. A provider who welcomes that coordination is a good sign that your care will be well managed across everyone involved in your recovery.
The Bottom Line
Most Bell’s palsy cases resolve within 3 to 6 months, especially when corticosteroid treatment begins within 72 hours of the first symptoms. Severity at onset, age, and speed of treatment are the three biggest factors that shape how long recovery takes. Supportive care, including facial exercises, eye protection, and the option of chiropractic care in Centennial, CO for nervous system support, can work alongside medical treatment to help you heal as fully as possible.
