• Dentin - layer, which is under the enamel. It comprises living cells which secrete solid minerals. Dentin seventy percent is made up of hydroxyapatite, twenty percent - from the organic material, and ten per cent - from the water. It has a yellowish color, and largely determines the color of the teeth as the enamel is partially transparent. Dentin formation begins before the formation of tooth enamel; unlike the latter, it continues to grow throughout life.
• Pulp - a softer, lively internal structure of the tooth. Through it are blood vessels and nerves of the teeth.
• Cementum - the layer of connective tissue, which firmly connects the roots of teeth with gums and jaws. It has a light yellow color - a little lighter dentin. It contains more fluoride than other mineralized tissues.
• Periodontal ligament - the tissue that holds the tooth in place.
