Dental infection: causes and treatment

No. Antibiotics may limit the spread of the infection and temporarily reduce symptoms, but they do not treat the cause. Without treatment by a dentist to clean the tooth or gums, the infection returns once the course of medication ends.

Yes. A fever indicates that the dental infection is beginning to spread through the body. This is an urgent warning sign that requires prompt consultation.

No. Never puncture, squeeze or attempt to drain an abscess yourself, as this can make the situation worse. See our dedicated page to learn how to recognise a dental abscess and know when to seek treatment.

No. A dental infection, whether tooth decay or an abscess, is not passed from one person to another through saliva like a virus.

Absolutely. Treating a dental infection during pregnancy is recommended. Bacteria may affect the health of the unborn baby or cause premature birth. Always tell the dental team that you are pregnant.

The roots of the upper teeth (premolars and molars) are very close to the maxillary sinuses. A dental infection in this area can spread to the sinus lining and cause sinusitis of dental origin.
