Do I Have a Dental Abscess?
Although tooth decay or a periodontal infection can be hard to detect at first, it's usually very easy to tell when an abscess forms. Unfortunately, the most significant dental abscess symptom is pain—the pain from a tooth abscess as continuous, sharp, and often harsh enough to be disruptive. You might experience trouble chewing, sensitivity to hot or cold foods, and even swollen lymph nodes, which help fight infection throughout the body.
You might also be able to feel the abscess in your mouth. In the case of a periodontal abscess, you may notice a swelling that looks like a pimple on your gums that may or may not be painful. You may also notice a bad taste in your mouth if the abscess is draining. Abscesses are active infections, and some people may also develop a fever.
