tooth decay - dental caries

A tooth is a hard and resistant organ that allows you to bite and grind food. The visible part of a healthy tooth is generally composed of a hard, white crown (enamel) and one or many roots implanted in the alveolar bone of your jaw. In addition to cutting and grinding food, teeth have an aesthetic role to play; they embellish your smile. Unfortunately, your teeth may become decayed and change color, this medical condition is called dental cavity (also known as dental caries or tooth decay).

Cavity is an irreversible alteration of the enamel and ivory of your tooth which gradually evolving the destruction of all other organs of the tooth. En general, cavity develops in 4 phases:

Phase 1 – during the first stage, the cavity is only in the enamel. The cavity is painless, because the enamel has no nerves. If you observe your teeth closely, you can detect the decay, but it is often unnoticed. The best way to detect the probem and treat it is visiting your dentist. That’s why it is important to see your dentist every 6 months.

Phase 2 – In phase 2, the tooth becomes sensitive to hot and cold. In addition, the tooth may have a little discoloration. You will likely discover the decay. Your dentist can remove the decayed tissue and fill the gap with either an amalgam or an appropriate restorative material.


Phase 3 – the third phase is characterized by a painful attack of the caries in the pulp, the soft tissue forming the inner part of your teeth and containing nerves and blood vessels. In phase 3, the cavity can not only cause pain, but also becomes more difficult to be repaired.

Phase 4 – phase 4 is the last stage of the cavity; the decay destroys the tooth pulp and cause severe pain. The infection can spread outside the tooth and causes inflammation of your gums (gingivitis). The decay requires medical attention to prevent severe pain, tooth loss or a rare form of infection called sepsis.

Your teeth are covered with a film of mucus and bacteria called bacterial plaque. Those microorganisms come from either food or other sources. To prevent them from attacking and destroy your teeth, regular brushing and flossing habit is essential.

Tobacco smoke – Smoking tobacco, including children exposed to passive smoking of parents, reduces salivation, weakens the immune system and promotes the growth of bacteria in your mouth. In fact, smoking not only increases the chance of tooth decay but also a variety of cancers.

  • Avoid frequent snacking – although it said that frequent snacking can help your metabolism and promote weight loss (controversial), having

nutrients in your mouth frequently  cause bacteria      to be more active thus facilitating formation of tooth decay.

Cancer treatment – Cancer treatment such as radiotherapy and chemotherapy can lead to a salivary hyposecretion (dry mouth). Saliva provides oxygen to your mouth and prevents overgrowth of bacteria and formation of tooth decay. Radiation therapy and most chemotherapy drugs destroy your salivary glands and the amount of oxygen in your mouth, putting you at higher risk of cavity. Treatment with corticosteroids may also be responsible for tooth decay.

Diseases – certain diseases such as diabetes mellitus, hyperthyroidism, hyperparathyroidism, and stress are causative agents of dental caries.
