Can tooth infection cause lightheadedness?

Having a tooth infection can cause discomfort even while performing daily routines. In most cases, it can cause swollen gums, throbbing pain and a sore jaw. Always bear in mind that dental problems can also lead to the development of complications such as lightheadedness and headaches.

What are the possible causes of tooth infection?

A tooth infection can be triggered by an abscess in a tooth or in the neighboring gums. An abscess is characterized as the build-up of pus that contains white blood cells, bacteria and dead tissue.

An individual can end up with a tooth infection if the exterior region of the tooth is damaged by a chip, cavity or break or has worn out. Bacteria enter the tooth via this break and cause an infection. Once the abscess reaches the roots of the tooth, the individual can experience discomfort, throbbing pain, swollen gums and face as well as sensitivity to hot and cold.

It is important to note that lightheadedness is a sensation of dizziness or faintness. The ear is responsible for controlling the sense of balance as well as hearing. The inner ear is comprised of a small-sized fluid-filled structure known as the labyrinth that assists the brain in finding the center of balance. If there is infection or damage to this area, it can lead to vertigo or dizziness. In some circumstances, a tooth infection can spread to the nerves of the ears which results to lightheadedness.


If an individual has a tooth infection, it can cause intense agonizing pain in the head and jaw. This can affect sleep and even trigger stress and episodes of anxiety. A tooth infection can also disrupt with the ability to eat.

All these factors can secondarily lead to lightheadedness that must subside once the infection clears up and the impairment to the tooth is fixed by a dentist.


The dentist is likely to provide a broad spectrum antibiotic to manage the tooth infection which attacks all the bacteria present in the abscess. A bacterial infection can be prevented from spreading to other parts of the mouth and head by ensuring that it clears up before the tooth is drilled and repaired with a filling.

Sedatives and sleeping aids might also be given if the oral issues prevent the individual from sleeping normally at night. Take note that all of these medications can trigger side effects including dizziness and lightheadedness.
