Its normal to experience temporary numbness after dental procedures like fillings, extractions, implants, or root canals. This is due to the local anesthesia used to keep you comfortable during treatment. Typically, numbness fades within a couple of hours. But what happens when numbness lingers longer than expected?
At McLevin Dental in Scarborough, your comfort and safety are always our top priorities. This guide will help you understand why prolonged numbness can occur after dental procedures, whats normal, how to manage it, and when to seek help.
What Causes Numbness After Dental Work?
Local anesthetic temporarily blocks nerve signals, preventing pain during dental procedures. Numbness may affect:
Lips
Tongue
Cheeks
Jaw area
Causes of prolonged numbness include:
Nerve proximity: Certain dental procedures, especially lower molar extractions or implant placements near the mandibular nerve, carry a small risk of temporary nerve irritation.
Swelling or bruising: Post-procedure inflammation can compress nerves.
Deeper injections: Some anesthetic injections placed near major nerves can take longer to wear off.
Rare nerve injury: In very rare cases, the needle or dental instruments may cause minor trauma to a nerve.
How Long Is Numbness Considered Normal?
Most numbness fades within 25 hours after the procedure.
Mild tingling or partial numbness may linger for 1224 hours in some cases.
If numbness persists beyond 2448 hours, its recommended to contact your dentist for evaluation.
How to Manage Numbness After Dental Procedures
1. Be PatientIt Often Resolves Naturally
In most cases, prolonged numbness is temporary.
The nerve heals over time, and sensation returns gradually.
2. Avoid Biting or Chewing on Numb Areas
Protect lips, cheeks, and tongue from accidental bites.
Stick to soft foods until feeling returns.
3. Apply Warm Compresses (After 24 Hours)
If numbness is due to swelling, gently apply a warm compress to the area to improve circulation and reduce pressure on nerves.
4. Gently Massage the Area
Light massage of the jaw or cheek (if not too sore) can stimulate blood flow and aid recovery.
5. Stay Hydrated
Good hydration supports overall healing.
When to Contact McLevin Dental
Call us if you experience:
Numbness lasting longer than 2448 hours
Tingling, burning, or electric-shock-like sensations

Any numbness that worsens instead of improves

Is Permanent Nerve Damage Possible?
Rare: Permanent numbness after dental procedures is extremely rare.
Most cases of nerve involvement resolve over weeks or months.
In the unlikely event of a more serious nerve injury, McLevin Dental will work closely with you to manage the condition and refer you to a specialist if needed.
How to Prevent Prolonged Numbness in the Future
Discuss any prior experiences with numbness before your procedure.
For procedures near nerves (like lower wisdom tooth removal or implants), your dentist will take extra precautions with imaging (X-rays or CBCT scans) to plan carefully.
Follow all post-procedure care instructions to minimize swelling and inflammation.
Your Comfort Is Our Priority
Prolonged numbness after dental procedures can feel concerning but is often a temporary and manageable part of the healing process. With time, care, and professional monitoring, most patients regain full sensation without complications.
