A numbing sensation can be a common side effect of dental procedures. It is caused by the use of anesthesia or novocaine, which numbs the area around the teeth and gums. This sensation can last for a few hours after leaving the dentist, but it will eventually wear off.

Some people may experience longer-term numbness, which could last for a day or two. It is important to keep in mind that everyone experiences numbing sensation differently and the length of time it lasts will vary from person to person.

What Dental Procedures Require Numbing?

When you go to the dentist, there’s a good chance that you’ll need to have some sort of numbing agent administered before any procedures can be done. This is because most dental work involves working in and around your mouth, which can be quite sensitive. Here are a few common dental procedures that require numbing:

Dental Fillings

When you get a cavity, your dentist will need to remove the decay and then fill the hole with a new material. This can be done using a local anesthetic, which numbs the area around the tooth so that you won’t feel anything.


A dental crown is used to cover up a damaged or discolored tooth. The procedure involves making an impression of your tooth so that the crown can be made, and then bonding the crown to your tooth. Local anesthesia is often used for this procedure as well.

Root Canals

A root canal is necessary when the nerve of a tooth becomes infected. This can be quite painful, so your dentist will numbing the area before starting the procedure.


If you have a tooth that needs to be removed, your dentist will first numb the area around it. This is because extractions can be quite painful, and you’ll likely feel some discomfort even with the numbing agent.

Dental Procedures That May Not Require Numbing

Though most dental procedures will require some sort of numbing agent, there are a few that may not. These include:


Dental cleanings are typically not painful, so they usually don’t require numbing. However, if you have sensitive teeth or gums, your dentist may use a local anesthetic to make sure you’re comfortable during the cleaning.


Dental X-rays are also not typically painful, though some people may feel a bit of discomfort from theX-ray machine. If you’re particularly sensitive, your dentist may use a local anesthetic.

As you can see, there are a variety of dental procedures that may require numbing. This is because most of these procedures involve working in and around your mouth, which can be quite sensitive. If you have a procedure coming up, be sure to ask your dentist if you’ll need to be numb before it starts.

How long does numbing last after you see the dentist?

Numbing typically lasts for a few hours after a dental procedure. However, it can vary depending on the individual and the procedure. If you have any concerns about how long the numbing will last, be sure to speak with your dentist. They can give you specific instructions on how to care for your mouth after the procedure.

Why do people experience different levels of numbness?

There are a few reasons why people experience different levels of numbness. The amount of anesthetic that the dentist uses can play a role, as well as the chemicals of your body. Additionally, your age and health can also affect how numb you feel. In general, younger and healthier people tend to feel less numbness than older or sicker individuals.

So, if you’re wondering why you felt more numbness than your friend during your last dental procedure, it could be due to any number of these factors. The best way to find out for sure is to ask your dentist. They’ll be able to give you more information on the anesthetic they used and how it could have affected your level of numbness.
