Tooth Abscess
A tooth abscess is a localized infection at the root of a tooth or in the surrounding gum tissue. It occurs when bacteria enter the tooth or gums and create pus, leading to discomfort and swelling. Treatment typically involves dental care, but understanding the condition can help guide next steps.
Oral & Dental- What exactly is happening in my tooth when I have an abscess?MedlinePlusMay 2026
A tooth abscess is a pocket of pus caused by a tooth infection, as described in the overview. The infection happens in the pulp (the soft center of your tooth that contains nerves and blood vessels), and your body creates this pus pocket to try to fight off the infection.
- How does a tooth infection turn into an abscess?MedlinePlusMay 2026
When bacteria get inside your tooth through decay or damage, they infect the pulp and spread to the root. Your body responds by creating a pocket of pus (the abscess) to contain the infection.
- Can cavities always lead to abscesses if not treated?MedlinePlusMay 2026
Not all untreated cavities become abscesses, but they can if the decay reaches deep enough into the tooth to infect the pulp. The longer a cavity goes untreated, the higher the risk it will develop into an abscess.
- Why do some people get more dental infections than others?MedlinePlusMay 2026
People who have poor oral hygiene, don't brush and floss regularly, eat lots of sugary foods, or have weak immune systems are more likely to get dental infections. Some people also have naturally more cavity-prone teeth.
- Will having one abscess make me prone to more?MedlinePlusMay 2026
Having one abscess doesn't automatically make you prone to more, but it does mean you may be at higher risk if you don't improve your oral hygiene habits. Treating the abscess and preventing future cavities is the best way to avoid another one.
