Make an appointment as soon as possible, and tell us you think you may have a dental abscess. You shouldn’t delay treatment for a dental abscess because it is a bacterial infection. If it is confirmed as a tooth abscess, your dentist may drain it and may also do a root canal treatment to make sure your tooth stays healthy. You may need antibiotics in certain cases.
Until you see your dentist, if the affected area is very sore, take an over-the-counter treatment, which contains both an anti-inflammatory and a painkiller, for example Ibuprofen, rather than a painkiller alone. Avoid hot foods and drinks and try to use the other side of your mouth. Don’t stop brushing your teeth but use a soft toothbrush around the affected area.
