Toothpaste is generally of which nature, helping it reduce acids present in the mouth?
Answer and explanation
Correct answer: Basic
Toothpaste is generally mildly basic, meaning it can react with and neutralise some acids produced in the mouth by bacterial activity. This reduces acidity and helps protect tooth enamel, so option B is correct. An acidic toothpaste would add to the harmful acidity, while a neutral substance would not provide the same acid-neutralising effect. “Salty” describes taste, not the relevant chemical nature.
