Bad breath is a common problem that affects a substantial number of people in all countries. It affects your rapport with colleagues or classmates. It can be a source of embarrassment. Bad breath may also be a sign of heath problem.

Normal Mouth Anatomy:

The structures in the mouth that can harbor bad breath are:

The teeth, the gums, and the tongue

Normally a tooth has 2 main parts:

Crownand Root

Crown is that part of teeth which is seen in the mouth.

Root is that part of tooth which is inside the jaw bone.

Crown is made up of: Enamel, Dentin and Pulp

Enamel: it is white hard covering over the crown. It does not have blood supply.

Dentin: It is below the enamel.

Pulp: The nerves and blood vessels present in the tooth are called pulp.

Gum or Gingiva:

Also known as periodontium is composed of bone and pink gummy tissue. It is a part of soft tissue lining of the mouth. They surround the teeth and provide seal around them .Healthy gingiva is usually coral pink in colour. Any change in colour, increased redness, swelling and increased tendency to bleed suggest an inflammation, possibly due to accumulation of bacterial plaque. This further leads to bad breath.


It is a muscular organ .It is covered with soft tissue called mucosa. The top surface of the tongue is the dorsal surface. The under surface of the tongue is the ventral surface. There are tiny hairs like projections on the surface of tongue, these are called papillae. There are 3 types of papillae but the one that is concerned here is filliform papillae. These papillae grow to a certain length and then break off. This shedding happens on the anterior part of tongue because of constant motion and frequent contact with the teeth.

This shedding is slower on the back part of tongue, so the papillae tend to grow longer. This is an ideal place for bacterial growth. This is what is called as coating of tongue.

What is Halitosis or bad breath?

Halitosis is an oral health condition characterized by unpleasant odour coming from mouth that can be caused by dental diseases or respiratory or gastric disorders.
