To digest food, we have to chew it in mouth and the saliva of the mouth is mixed with the food to make it lubricant. The enzymes present in the saliva digests the food, which is swallowed to move down to the esophagus, which is the food pipe connecting the mouth to the stomach. Esophagus moves through the warm area of the body and when the food is moved down the esophagus, it temperature increases, which helps the enzymes to easily digest the food. Esophagus has a rhythmic muscular contraction, which is called peristalses and it helps the food to move to the stomach.
Disorders of mouth: Some of the common forms of mouth disorders are tooth decay, herpes simplex, mouth ulcers, epiglottitis, hand-foot-mouth disease, glossitis, herpes stomatitis, tonsillitis and salivary gland infection.
Tooth decay: It is one of the common mouth problems, which can be seen in youngsters and children. The food component sticks to the teeth causing in loss of the teeth in tooth decay and regular care of teeth is required to prevent tooth decay.
Herpes simplex: It is a viral infection and oral herpes can be found in mouth, which is called cold sores. Herpes stomatitis is also caused by herpes simplex infection.
Mouth ulcer: Mouth ulcer is also called canker sore, and it is a health problem in which, the open sores are formed inside the mouth.
Epiglottitis: Epiglottis helps the food to go into the food pipe and prevents it from going into the nasal track. The inflammation to epiglottis is called Epiglottitis.
Hand-foot and mouth diesease: The disease is caused by viral infection and it can be found in children, who come in direct contact with the saliva or faces of the infected person.

Tonsilities salivary gland infection: Tonsilitis is caused due to infections in tonsils and it may cause swelling of the tonsils.
Esophagus disorders: Common form of esophagus disorders can be categorized in four - structural disorders, inflammations, motility disorder and malignancies.
Structural disorders: EA and TEF - EA is esophageal atresia and TEF is trachoesophageal fistula.
Esophageal atresia: This is the condition, in which the upper part of the esopahgeus goes into the blind pouch, which causes blockage and it is one of the life threatening condition found in new born babies.
Tracheoesophageal fistula: The esophageus is connected to trachea, which is, the windpipe and it causes breathing problems, which may becomes fatal.
Inflammations to Esophagus: The most common form of esophagus disorder is gastroesophageal reflux, in which, the muscles of the esophagus is not closed properly and it causes the stomach content to go back into the oesophagus.
Motility abnormalities: The problem causes difficulties in swallowing and it is caused by the abnormal contraction or movement of one of the two muscles found in esophagus.
Malignancies: One of the common cancers of esophagus is adenocarcinoma.
