Tooth enamel is the hardest substance in thebody. It does not dissolve...
- pH change as the cause of tooth decay Tooth decay starts when the pH of the mouth is lower than 5.5.
- Tooth enamel, made up of calcium hydroxyapatite (a crystalline form of calcium phosphate) is the hardest substance in the body. Hence, option (a) is the correct answer.
- It does not dissolve in water but is corroded when the pH in the mouth is below 5.5.
- Bacteria present in the mouth produce acids by degradation of sugar and food particles remaining in the mouth after eating.

Tooth enamel is the hardest substance in thebody. It does not dissolve...
Composition of Tooth Enamel
Tooth enamel is primarily composed of calcium phosphate, which is a mineral made up of calcium and phosphate ions. This mineral makes up approximately 96% of the enamel's composition, giving it its characteristic hardness and strength.
Role of Calcium Phosphate
Calcium phosphate plays a crucial role in protecting the underlying dentin and pulp of the tooth from damage and decay. It forms a dense crystalline structure that acts as a barrier against bacteria, acids, and other harmful substances that can erode the tooth enamel.
Effects of Low pH
When the pH in the mouth drops below 5.5, the acidic environment can lead to the demineralization of tooth enamel. This occurs because the acid can break down the calcium phosphate crystals, weakening the enamel and making it more susceptible to decay and erosion.
Importance of Calcium Phosphate
The presence of calcium phosphate in tooth enamel is essential for maintaining overall oral health. It helps to keep the teeth strong and resistant to damage, ensuring that they can effectively perform their functions of chewing and biting.
In conclusion, calcium phosphate is a vital component of tooth enamel, providing it with the necessary strength and protection against decay. Maintaining a proper pH balance in the mouth is crucial for preserving the integrity of the enamel and preventing dental issues.
