If there is any exudate oozing from the gums around your tooth, it is a sign that there is an infection at this tooth. The blood and/or pus may be coming from the tooth itself if you have deep decay on it, or it may be coming from the gums surrounding the tooth if you have gum disease. If you see blood or pus around your teeth, please come in and see us as soon as you can. In the meantime, gently massaging the area and using a warm salt water rinse (dissolve some salt in warm water and gargle with it) may help to control the signs and symptoms.
