Can You Smoke After a Root Canal

When it comes to the million and one things you have to consider after a root canal, smoking is probably the last thing on your list. But for smokers (or those who like to indulge in an occasional cigar or pipe), you may be wondering if it’s okay to light up after having this particular dental procedure done.

Let’s discuss why smoking is a no-no when it comes to root canals, and why it’s best to avoid other forms of tobacco as well. 

Why You Should Avoid Smoking after Root Canal 

Smoking has long been linked to oral health complications such as gum disease and tooth decay. That’s why dentists typically advise patients to cut back on or completely stop smoking if they want to maintain good oral hygiene.

The same holds true for those who have recently had a root canal. Here are three important reasons why smoking should be avoided after a root canal procedure: 

1. Slows Down Healing Time

When you smoke after a root canal procedure, it can impede your body’s ability to heal properly and increase your risk of developing an infection.

This is particularly true when it comes to healing the area around the gums and teeth since nicotine slows down blood flow and reduces oxygen levels in the bloodstream, both of which are necessary for proper healing after dental surgery. Plus, nicotine can also cause inflammation, which can further delay recovery time.

2. Increases Risk of Complications

In addition to slowing down healing time, smoking can also increase your risk of experiencing complications following your root canal treatment.

For example, if you smoke too soon after the procedure, you could end up with a dry socket, a painful condition that occurs when the clot that forms over the wound breaks away prematurely due to pressure from hot air or liquids like alcohol or coffee.

3. Impairs Tooth Restoration Process

Depending on what type of dental work was done during your root canal procedure (i.e., crown placement), smoking can also interfere with this process by causing discoloration of restorative material such as porcelain veneers or crowns as well as staining around fillings or sealants placed near areas where smoking occurred. Plus, since nicotine causes the contraction of blood vessels in the mouth, these areas may not receive enough oxygen for proper healing either.

Can You Smoke After a Root Canal with Temporary Filling?

Smoking after a root canal procedure is never recommended, regardless of whether or not you have had a temporary filling. Not only can smoking slow down the healing process, but it can also increase your risk of experiencing complications and impair the tooth restoration process.

How long after a root canal can you smoke?

Smoking should be avoided for at least 48 hours after having a root canal procedure done. This is because smoking will slow down the healing process, increase your risk of complications, and impair the tooth restoration process.

Furthermore, nicotine can also cause inflammation which could further delay recovery time. Therefore, it’s best to avoid all forms of tobacco (including cigarettes, cigars, pipes, etc.) following a root canal in order to ensure that your body has enough time to heal properly.

How Smoking Can Impact Your Recovery After a Root Canal 

Smoking can have an extremely detrimental effect on the healing process after a root canal procedure. When smoked, nicotine and other chemicals contained in cigarettes constrict blood vessels, reducing the amount of oxygen contained in the bloodstream which is essential for a proper healing process. As a result, smoking can significantly delay recovery times in comparison to those not exposed to smoke.

Furthermore, smoking can increase inflammation throughout the body’s systems. While inflammation is typically beneficial for the healing process, even natural levels of inflammation may be too much for recently operated areas like after a root canal.

Additionally, increased inflammation increases the risk of infections occurring at and around the site of a procedure due to weakened immune responses caused by smoking; this can lead to more complex medical problems requiring further treatment or even surgery if left untreated. 


While some people may think they can get away with smoking after a root canal without any consequences, this is never recommended. Smoking has been linked to decreased blood flow in areas where procedures were performed and can increase your risk of infection and other complications.

Additionally, the nicotine contained in cigarettes or other forms of tobacco should be avoided for at least several days following your root canal so that your body has time to heal fully before being exposed again!

For tooth patients in the United States looking for advice about whether they are able to smoke after their root canal procedures, we recommend avoiding all forms of tobacco until you have completely healed from the procedure! That way you won’t risk having any complications due to smoking too soon afterward.
