How to get the effects of novocaine to wear off? Safely and quickly

5 min read

The numb, tingly sensation from dental anesthetics like Novocaine can linger for several hours, with numbness in the lips and tongue sometimes lasting longer than the teeth. While patience is the most reliable remedy, there are several proven strategies and clinical options to help speed up the process for those wondering how to get the effects of novocaine to wear off faster.

Quick Summary

Learn effective methods to reduce lingering numbness after a dental procedure. Options range from gentle at-home remedies like warm compresses and light activity to clinical reversal agents. The duration depends on the anesthetic and dosage.

Key Points

  • Increase Blood Flow: Applying a warm compress, light exercise, or gentle facial massage can help boost circulation, which flushes the anesthetic out of the system more quickly.

  • Inquire About a Reversal Injection: For those needing rapid recovery, a clinical reversal agent like OraVerse® can cut the numbing time in half but often costs extra and isn't covered by insurance.

  • Be Patient and Protect Yourself: The numbness will wear off naturally within a few hours. While you wait, avoid eating solid or hot foods and refrain from biting your lip or cheek accidentally.

  • Understand the Anesthetic Used: The duration of numbness depends on the type, dosage, and whether a vasoconstrictor like epinephrine was used. Not all anesthetics are the same.

  • Contact Your Dentist for Persistent Numbness: If numbness lasts for more than 6-8 hours or a full day, or if you experience unusual side effects, it is best to contact your dentist for guidance.

  • Avoid Alcohol and Caffeine: Consuming these substances after receiving novocaine may interfere with the body's metabolism and elimination of the anesthetic.

  • Move Your Mouth Gently: Simple facial movements, such as talking, can stimulate blood flow to the facial muscles, potentially helping the anesthetic wear off faster.

Understanding Dental Anesthetics

Novocaine is a brand name that has become a catch-all term for local dental anesthetics, though modern dentistry often uses alternatives like lidocaine, articaine, and mepivacaine. These medications are known as local anesthetics and work by temporarily blocking nerve signals to the brain, preventing you from feeling pain during a procedure. The numb sensation will naturally fade as your body metabolizes the medication and blood flow carries it away from the injection site. The overall duration of numbness depends on several factors, including the type and amount of anesthetic used, the injection location, and your individual metabolism.

Natural Methods to Expedite Recovery

For those seeking to reduce the lingering numbness, several safe, at-home methods can help accelerate blood flow to the area. Increased circulation helps your body flush out the anesthetic more quickly.

  • Apply a Warm Compress: Applying gentle heat to the outside of your cheek, near the injection site, can help increase blood flow. Soak a clean washcloth in warm (not hot) water, wring it out, and apply it for 15-20 minutes at a time. Remember to test the temperature on your wrist first to avoid burns, as the numb area won't feel heat normally.
  • Engage in Light Physical Activity: A brisk walk or light exercise can increase your overall metabolism and blood circulation, helping your body process and eliminate the anesthetic faster. It's crucial to follow your dentist's post-procedure instructions, especially after extensive oral surgery, to ensure you don't overexert yourself.
  • Gently Massage the Area: Using clean fingertips, gently massage the outside of your cheek in a circular motion. This stimulates blood flow and can help the anesthetic dissipate faster. Be very careful not to press too hard or touch the immediate injection site, especially if there is any swelling or pain.
  • Move Your Mouth and Jaw: Lightly exercising your jaw by talking or gently chewing on soft foods (once you regain enough feeling to do so safely) can stimulate blood flow to the facial muscles. This encourages the anesthetic to be absorbed more quickly. Just be mindful not to bite your tongue or cheek accidentally while they are still numb.
  • Stay Hydrated: Drinking plenty of water helps your body's natural processes, including flushing out medications. Staying hydrated is always a good practice and can support your body's ability to metabolize the anesthetic efficiently.

Clinical Option: The Reversal Injection

Some dentists offer a clinical reversal agent to speed up the process significantly. The most common is a product called OraVerse®.

How OraVerse® Works

OraVerse® (Phentolamine Mesylate) is an alpha-adrenergic blocker that works by reversing the vasoconstrictive effects of the anesthetic, which is often mixed with epinephrine to prolong the numbing effect. By increasing blood flow to the treated area, OraVerse® can help restore sensation to the lips and tongue in about half the normal time. This injection is administered by your dentist immediately after your procedure is complete.

Is OraVerse® Right for You?

While an effective option, OraVerse® may not be for everyone. It is typically a patient-pay service and not covered by most dental insurance plans. It is most beneficial for those who have a critical event, such as a work meeting or social engagement, shortly after their dental appointment. You should discuss this option with your dentist before your procedure to see if it is a suitable choice for you.

Comparison of Methods

Method How It Works Application Timeframe Notes
Warm Compress Increases localized blood flow. Applied to the outside of the cheek for 15-20 minutes. Helps speed up the process, but results vary. Test temperature carefully to avoid burns.
Gentle Massage Stimulates circulation to the face. Gently massage cheek and jaw with clean hands. Gradual, depends on individual response. Do not massage the immediate injection site.
Light Exercise Boosts overall metabolism and blood flow. Brisk walking or other gentle activity. Accelerates the flushing of the anesthetic. Consult your dentist, especially after surgery.
Move Mouth & Jaw Stimulates blood flow in oral muscles. Talking or chewing very soft food carefully. Helps encourage sensation to return. Be very cautious to avoid biting yourself.
Reversal Injection Reverses vasoconstriction, increasing blood flow directly. A second injection administered by the dentist. Can cut numbness time in half. Additional cost, requires dentist to administer.

What to Avoid While Waiting for the Numbness to Subside

While you wait for sensation to return, it's essential to protect yourself from accidental injury. Since your mouth is numb, you may not be aware of damaging delicate tissues.

  • Avoid Eating Solid Foods: Wait until full sensation has returned before eating solid foods to prevent accidentally biting your tongue, lip, or cheek.
  • Avoid Hot Liquids: Your mouth cannot accurately register temperature while numb, so you could easily burn yourself with a hot drink.
  • Refrain from Touching the Area: Avoid poking or prodding the injection site or the numb areas with your fingers. This can introduce bacteria and cause irritation.

When to Seek Professional Advice

For the vast majority of people, lingering numbness is a temporary and harmless side effect that resolves within a few hours. However, in extremely rare cases, numbness can last longer than expected. If your numbness persists for more than 6-8 hours or a full day, it is wise to contact your dentist. Though uncommon, this could indicate a nerve irritation or another underlying issue that a professional should assess.

Conclusion

Although the numb sensation after a dental procedure is a temporary annoyance, you can take proactive steps to help it resolve faster. By combining simple, safe at-home strategies like warm compresses, gentle massage, and light exercise with the option of a clinical reversal injection like OraVerse®, you can encourage the anesthetic to wear off more quickly. Above all, prioritize safety by waiting to eat until your full sensation has returned and consult your dentist if the numbness persists beyond the expected duration. The best approach is to communicate your concerns and preferences with your dental provider, who can offer the best advice tailored to your specific situation.
