You likely have a tooth abscess forming from a dead tooth canal or perhaps you’re just getting food stuck between your teeth. A tooth abscess is a cavity full of pus and can potentially spread to other areas of your body and make you very unwell. Food caught between the teeth will lead to periodontitis and/or tooth decay. Either way it’s important you see a dentist.
