Dental Abscess

A dental abscess occurs when bacteria infect the pulp chamber of a tooth (e.g., from a fractured tooth or severe periodontal disease) or the surrounding bone. This infection leads to a collection of pus, which can cause significant pain and swelling. Common signs include facial swelling (often below the eye if an upper tooth is affected), reluctance to chew on one side of the mouth, bad breath, or lethargy. In some cases, the abscess may rupture, creating a draining tract (fistula) on the face or inside the mouth. Dental abscesses are painful and require prompt veterinary attention. Treatment typically involves extracting the affected tooth or performing a root canal, along with antibiotics to control the infection. Early diagnosis and intervention are key to relieving the pet's discomfort and preventing further complications.
