A mouth ulcer is a painful round or oval shallow lesion in the mouth, often on the inside of cheek but can occur on the gums, palate or lips. They are not infectious so cannot be passed on from sharing a drink or kissing someone. Whilst they are very common and generally self-limiting, it is often not known exactly how one has been caused.

A dental abscess is an accumulation of pus that forms inside a tooth or gum. The abscess typically originates from a bacterial infection that makes its way into a tooth.
Your mouth is full of bacteria, which combine with small particles of food and saliva to form a sticky film called plaque, which builds up on your teeth. If the plaque is not removed by regular and proper tooth brushing, the bacteria can attack the teeth and gums, which compromises their health and can lead to the formation of a dental abscess.
