How Long Does Dental Numbing Last? Wear Off Novocaine

How Long Does Dental Numbing Last

After leaving the dentist’s clinic, you may feel dental numbing for 1 – 2 hours on average. But in some rare cases, your mouth will be numb for up to 5 hours. However, anything more than that could be a sign of something serious so that you need to contact your dentist immediately.

Now, let’s understand why dental numbing happens.

Before any dental treatment, dentists are required to give you a dose of anaesthesia to numb the specific area so that you do not feel the pain or have to go through the excruciating experience of dental procedures. In this article, you will learn about numbing and usually how long it takes for the numbing to last after a procedure.

Local anaesthesia lets you stay awake. However, you cannot feel any pain or have any sensation of the treatment inside your mouth. Novocaine and similar drugs are used during tooth removal or filling a cavity. Novocaine is popular among the local anaesthesia drugs because it lasts longer and gives a prolonged numbness after dental work.

What is Novocaine used for?

Novocaine is local anaesthesia, commonly called Procaine. It is generally used in specific dental regions around a tooth to help numb the vicinity. This helps you to undergo the dental procedure without realizing the pain otherwise.

How is Novocaine injected?

The procedure involves the doctor initially drying your mouth using air or cotton balls. After that, he applies a numbing gel before injecting the anaesthesia into the region surrounding the affected tooth. Upon injection, you feel a slight stinge, not because of the syringe but because of the anaesthesia making its way into the tissue. Within a few minutes, the drug starts working, and your mouth will be numb. 

You may feel slight pressure but won’t feel any pain. Once the anaesthesia wears off, your tooth will first feel the sensation, followed by your lips and tongue. 

What is the duration of Novocaine?

Generally, the effect of Novocaine lasts for 30 to 60 minutes. However, if the anaesthesia is given alongside adrenaline, such as epinephrine, the duration could go on for a prolonged 90 minutes. 

You have to note that just like other drugs, even Novocaine’s effect may change owing to several factors.
