Question

The bacteria that cause tooth decay have a capsule. What does this tell you about the relative effectiveness of a toothbrush with stiff bristles and one with soft bristles?

A) Stiff bristles are more effective
B) Soft bristles are more effective
C) Capsules don't affect tooth decay
D) Both are equally effective

Answer 1

The presence of a capsule in bacteria that cause tooth decay does not indicate the relative effectiveness of toothbrushes with stiff or soft bristles. Toothbrush effectiveness depends on various factors, and it is important to use a toothbrush with soft bristles to prevent damage.

Step-by-step explanation:

The presence of a capsule in the bacteria that cause tooth decay does not directly indicate the relative effectiveness of toothbrushes with stiff or soft bristles. The effectiveness of a toothbrush in removing plaque and preventing tooth decay depends on various factors such as bristle design, brushing technique, and frequency of brushing. It is important to use a toothbrush with soft bristles to avoid damaging the tooth enamel and gums. Additionally, regular brushing and proper oral hygiene practices are essential in preventing tooth decay.
