Our mouth is made up of hard and soft tissues. Hard tissue comprises of teeth and bone and soft tissue is comprised of our gums, tongue, cheeks and the muscles. Teeth are fixed in the bone with the help of a ligament called periodontal ligament. The teeth and bone are covered by our gums, and the whole complex of teeth and gums is surrounded by tongue on inside and cheeks on the outside of the mouth.
During our life time many problems can occur to hard and soft tissues which cause damage to our mouth.
