Can Cavity Fillings Cause Nosebleeds?

Having a cavity filled is already a process that no one likes to go through. It is usually preceded by a pretty large amount of pain and discomfort in the area and then you need to go to a dentist to get it fixed. All of this can be painful and frustrating and can have effects even after your filling has been put in. But are nosebleeds after you get a filling caused by the filling itself? Our Port Orange dentist has some information about this topic.

The short answer is no, there is no real evidence to suggest that having a dental filling makes you any more likely to have a nosebleed or any evidence that the filling themselves contribute to nosebleeds.

Nosebleeds, however, are a relatively common side effect of some dental procedures, especially surgical procedures and procedures involving the top row of teeth.

Root Canals

Root canals can cause nosebleeds to occur in a few scenarios. If the root canal does not remove all of the decay or infection then nosebleeds can occur after it is done. Root canals along the top row of teeth can also cause nosebleeds by affecting an area called Kiesselbach’s Plexus, a small area between the mouth and nose. This area can be exposed and then can become dry which can cause nosebleeds in the days after a root canal. This is only a temporary side effect though.


Anesthesia is a common cause of nosebleeds after dental procedures so if you were sedated when your filling was put in, the nosebleeds may be because of that rather than the filling itself. Much like the situation described in the last part, anesthesia or sedation can cause parts of your nose and sinuses to become dry which can lead to nosebleeds. This is also a temporary side effect and should correct itself after a couple of days.


Another less common cause of nosebleeds as a side effect of dental work is stress. Stress can have a wide ranging list of effects on the body and nosebleeds are included in that list. If you have a lot of stress leading up to or during the dental procedure then it is possible to have nosebleeds after it is complete. This too should only be a temporary side effect.

Nosebleeds are not caused by having fillings, at least not directly, but you can suffer from nosebleeds after you visit the dentist. If your nosebleeds are not long lasting and if you can manage the bleeding, then they are a minor issue. If they do last a long time or if the bleeding becomes unmanageable, then contact your dentist or a doctor depending on the severity of the situation.
