Oral Infection

An oral infection occurs when bacteria, viruses, or fungi multiply in the mouth and overwhelm the body’s natural defenses. These infections can affect the teeth, gums, tongue, cheeks, or throat and may cause pain, swelling, redness, or difficulty eating and speaking. Oral infections often develop when oral hygiene is compromised, but they can also result from injuries, weakened immunity, or untreated dental problems.

Common symptoms include persistent tooth or gum pain, swelling, bad breath, pus, fever, sensitivity, or sores that do not heal. Infections such as abscesses, gum disease, and oral thrush can worsen quickly if left untreated and may spread beyond the mouth in more serious cases.

Early recognition is important, as prompt treatment can prevent complications and relieve discomfort sooner. Management may involve improved oral care, prescribed medications, or dental procedures, depending on the cause and severity of the infection. This section explores the most common types of oral infections, typical warning signs, and treatment options, as well as guidance on when urgent medical or dental care is needed.
