What causes dental tooth decay(8 marks)?

1. Poor oral hygiene: Not brushing and flossing regularly allows plaque to build up on the teeth, which contains bacteria that produce acids that can erode tooth enamel and cause decay.

2. High sugar and carbohydrate intake: Consuming foods and drinks that are high in sugar and carbohydrates provides fuel for the bacteria in the mouth to produce acids that attack the teeth.

3. Acidic foods and drinks: Frequent consumption of acidic foods and drinks, such as citrus fruits, soda, and sports drinks, can weaken tooth enamel and make it more susceptible to decay.

4. Dry mouth: Saliva helps to neutralize acids and wash away food particles, so having a dry mouth due to certain medications, medical conditions, or breathing through the mouth can increase the risk of tooth decay.

5. Genetics: Some individuals may have inherited weaker tooth enamel or a higher susceptibility to tooth decay, making them more prone to developing cavities.

6. Age: As people age, the risk of tooth decay increases due to factors such as receding gums, decreased saliva production, and a longer exposure time to acids and bacteria.

7. Dental fillings and restorations: Over time, dental fillings and restorations can weaken or break down, creating spaces where bacteria can accumulate and cause decay around the restoration.

8. Poor nutrition: A diet lacking in essential nutrients, such as calcium, vitamin D, and fluoride, can weaken tooth enamel and increase the risk of tooth decay.
