Black hairy tongue is not a deadly disease. It is a harmless condition where the papillae on the surface of the tongue become elongated and take on a black or brown appearance.

Toothbrushes should be replaced every ___________ months.
Correct Answer
A. 2-3
Explanation
Toothbrushes should be replaced every 2-3 months because over time, the bristles on a toothbrush can become frayed and less effective at removing plaque and bacteria from the teeth and gums. Additionally, using a toothbrush for too long can lead to the accumulation of bacteria, which can potentially cause oral health issues. Regularly replacing toothbrushes helps maintain good oral hygiene and ensures that the toothbrush is in optimal condition for effective cleaning.
5.
Which of the following usually precedes gum disease?
Correct Answer
C. Gingivitis
Explanation
Gingivitis usually precedes gum disease. Gingivitis is the inflammation of the gums caused by plaque buildup on the teeth. If left untreated, it can progress to gum disease, also known as periodontitis, which is a more severe infection that can lead to tooth loss. Cavities, on the other hand, are caused by tooth decay and are not directly related to gum disease. Therefore, gingivitis is the correct answer as it is the initial stage of gum disease.

Bacteria that live on your teeth can cause both bad breath and cavities. The bacteria produce acids that break down food particles, leading to the formation of plaque and cavities. Additionally, the bacteria release foul-smelling compounds as they break down food, resulting in bad breath. Therefore, the presence of bacteria on teeth is responsible for both of these oral health issues.

Whitening toothpastes work by __________________
Correct Answer
A. Removing stains from teeth
Explanation
Whitening toothpastes work by removing stains from teeth. These toothpastes contain abrasive particles that help to scrub away surface stains caused by coffee, tea, tobacco, and other factors. They work to gently polish the teeth, making them appear brighter and whiter. Unlike bleaching agents, whitening toothpastes do not actually change the color of the tooth enamel. Instead, they focus on removing surface stains to improve the overall appearance of the teeth. Additionally, some whitening toothpastes may also contain chemical agents that help to dissolve or break down stains for more effective stain removal.
