An infection can arise when bacteria gets inside a tooth. Not everyone with a tooth infection will feel pain, yet they will still require treatment from a dentist to prevent the infection from spreading.

Key takeaways:
-  A tooth’s inner tissue can die due to an infection, resulting in an absence of pain although the infection still exists.
-  An infection can be ongoing even without any pain and it will worsen without treatment.
-  Have your teeth examined regularly by a dentist to check for infection.

"Getting treatment is essential because the infection can spread to the tissues around the tooth, and may even enter the bloodstream, at which point it can become life-threatening."
