Amongst the following, which compounds control the tooth decay:
Correct answer: D. A fluoride compound
- A. An Iodide compound
- B. A bromide compound
- C. A chloride compound
- D. A fluoride compound
Explanation
Fluoride is a compound that helps prevent tooth decay by strengthening tooth enamel and making it more resistant to acid attacks from bacteria. It can be found in toothpaste, mouthwash, and even in some drinking water sources. Fluoride ions replace hydroxide ions in the enamel, forming a more stable compound that is less susceptible to decay. Iodide, chloride, and bromide are not as effective in preventing tooth decay as fluoride.
