Your teeth are composed of four dental tissues. Three of themâenamel, dentin and cementumâare hard tissues. The fourth tissueâpulp, or the center of the tooth that contains nerves, blood vessels and connective tissueâis a soft, or non-calcified, tissue.
There are 3 types of dental abscess: 1  Gingival abscess-the abscess is only in the gum tissue and does not affect the tooth or the periodontal ligament. 2  Periodontal abscess-this abscess starts in the supporting bone tissue structures of the teeth.
