After a visit to the Perth dentist, whether for a filling, root canal, or tooth extraction, the use of local anesthesia is a common part of the process to ensure that you stay comfortable during the procedure. While local anesthesia is an essential tool for pain management, many patients wonder how long the numbness lasts and what they should expect after the appointment. In this blog, we’ll explain how long the numbness typically lasts after dental work, factors that can influence this duration, and what to do if it doesn’t wear off as expected.
What is Local Anesthesia?
Local anesthesia is a numbing agent that your Perth dentist applies to a specific area of your mouth before a dental procedure. It temporarily blocks the nerve signals in that area, preventing pain and discomfort during treatments such as fillings, extractions, and cleanings. Unlike general anesthesia, which affects your entire body, local anesthesia only numbs the treated area.
There are different types of local anesthetics, and the most common ones include:
- Lidocaine
- Articaine
- Bupivacaine
These anesthetics work by blocking nerve receptors in the area of your treatment, ensuring you don’t feel pain during the procedure. However, once the anesthesia starts to wear off, sensations like tingling or numbness can be experienced as your nerves begin to regain feeling.
How Long Does Numbness Last After a Dental Visit?
The duration of numbness after a dental procedure depends on several factors, including the type of anesthetic used, the procedure performed, and individual variations. However, here are some general guidelines:
1. Standard Duration:
- Most numbness lasts between 2 and 4 hours after a dental procedure, depending on the strength of the anesthesia used. For minor treatments like fillings or cleanings, the numbness typically wears off in a few hours.
- Stronger anesthetics or larger areas of numbing (e.g., for a root canal or tooth extraction) can result in numbness lasting longer, sometimes up to 5 or 6 hours.
2. Factors That Influence Numbness Duration:
- Type of anesthesia: Some anesthetics, like bupivacaine, are longer-acting and can keep you numb for several hours.
- Location of treatment: Procedures that involve more extensive numbing, like those in the lower jaw or near the back teeth, might result in longer-lasting numbness.
- Personal factors: Your metabolism, age, and overall health can influence how quickly your body processes and eliminates the anesthetic. Some people may metabolise anesthesia more slowly, which could result in prolonged numbness.
- Amount of anesthesia used: The more anesthetic your Perth dentist administers, the longer the numbness may last.
What to Expect as the Numbness Wears Off:
As the numbness begins to fade, you may experience a few sensations:
- Tingling or a “pins and needles” feeling: This is normal and typically happens as the nerves start to wake up.
- Slight discomfort or sensitivity: The area where the anesthesia was administered may feel sore or sensitive for a short period after the numbness wears off. This is especially common after more invasive treatments like tooth extractions or root canals.
- Gradual return of sensation: In most cases, the numbness will gradually fade, and you will regain full sensation within a few hours. If you experience any sharp pain or discomfort that doesn’t subside, it’s important to contact your Perth dentist to rule out any complications.
What to Do While You’re Numb:
While you’re still numb, there are some things you should avoid doing to prevent injury or discomfort:
- Avoid chewing or biting: The numbness makes it hard to feel what’s in your mouth, so you might accidentally bite your cheek, lip, or tongue, which can lead to injury. It’s best to wait until the numbness has worn off completely before eating or drinking.
- Be cautious with hot drinks: Since you won’t be able to feel the temperature of hot beverages, you could accidentally burn yourself. It’s a good idea to wait until the numbness has subsided before drinking anything hot.
- Don’t speak too much: Numbness in your lips and mouth can make it harder to talk clearly, so it’s best to avoid conversations that require too much talking until you can feel your mouth again.
What If the Numbness Doesn’t Wear Off?
In rare cases, numbness can last longer than expected. If the numbness lasts for more than 6 hours or if you experience unusual symptoms such as extreme pain, swelling, or signs of infection, it’s important to contact your Perth dentist immediately. Prolonged numbness could indicate issues with the nerve, an allergic reaction to the anesthesia, or an underlying problem that needs attention.
Here are a few things to consider:
- If the numbness persists on one side of your mouth, it could be due to a nerve being affected during the injection. Although this is rare, it’s always a good idea to check in with your dentist.
- Unusual pain or swelling: If numbness is accompanied by discomfort, this could be a sign of infection or other complications that require professional care.
What to Do if Numbness Lasts Longer Than Expected:
- Contact your dentist: If you’ve been waiting for more than 6 hours for the numbness to wear off, don’t hesitate to call your Perth dentist. They can assess whether this is a normal reaction or if further treatment is needed.
- Monitor your symptoms: Keep an eye on any changes to your symptoms, such as increasing pain, swelling, or changes in sensation. Any unusual or concerning symptoms should be reported to your dentist right away.
Conclusion:
Numbness after a dental procedure is a normal part of the recovery process, and while it usually lasts between 2 and 4 hours, it can vary based on several factors. By following your Perth dentist’s post-treatment instructions and being mindful of the sensations as they return, you can ensure a smooth recovery.

FAQs
- How long does dental numbness usually last?
Numbness from local anaesthetic typically wears off within 1 to 3 hours after your dental procedure, depending on the dose and injection site. - What if the numbness lasts longer than expected?
Mild variations are normal, but if numbness persists for more than 5 hours, contact your Perth dentist to rule out nerve irritation or other issues. - Can I eat while my mouth is still numb?
It’s best to wait until the numbness fully wears off. Eating while numb can lead to accidentally biting your cheek, tongue, or lip. - Is there a way to make the numbness go away faster?
Chewing gently (on the opposite side), moving your mouth, or applying a warm compress to the outside of your cheek can help stimulate blood flow and speed up the process. - Is numbness the same for every dental procedure?
Not always. Numbness duration can vary depending on the type of procedure, location in the mouth, and the type of anaesthetic used.
