How Long Does Numbness Last After Jaw Surgery?
Numbness is one of the most common and concerning side effects. Here is a realistic timeline for nerve recovery.
Numbness after orthognathic surgery is very common, and the recovery timeline varies by person. Here is what you can expect.
Typical numbness timeline:
| Time Period | What to Expect |
|---|---|
| 1β4 weeks | Complete numbness in affected areas (lower lip, chin) |
| 1β3 months | Tingling, pins-and-needles, or "waking up" sensation begins |
| 3β6 months | Sensation gradually returns β often in patches |
| 6β12 months | Most recovery occurs during this period |
| 12+ months | Any remaining numbness is likely permanent |
- Lower lip and chin (numbness rates):
- 90% of patients notice some numbness after lower jaw surgery
- 80β85% regain full or nearly full sensation within 12 months
- 10β15% have some permanent sensory change (mild to moderate)
- 2β5% have significant permanent numbness
- Upper lip and cheek (less common):
- Numbness occurs less frequently and typically resolves faster
- Most patients recover fully within 3β6 months
What Numbness Feels Like
- "Frozen" or "Novocaine that never wears off"
- May change to tingling, itching, or burning as nerves recover
- Some areas may feel "thick" or "different"
How to Cope
- Be careful with hot foods and drinks (you may not feel temperature)
- Be careful when shaving or applying makeup
- Use a mirror to check for food on your lip
- Most patients adapt quickly
Clinical Guidance
Numbness after jaw surgery is very common but usually temporary. Most sensation returns within 6β12 months. Permanent numbness is rare (2β5%) and is usually partial rather than complete. The first few months of tingling and "pins and needles" are actually a good sign that nerves are recovering.
