Which of the following is a common component in toothpaste, for cleaning the teeth by neutralising the excess acid to prevent tooth decay?

Correct option is A

The correct answer is (A) Bases

Explanation:

• Bases are commonly used in toothpaste to neutralize excess acid in the mouth, which helps to prevent tooth decay.
• One of the most common bases in toothpaste is sodium bicarbonate (baking soda), which is mildly alkaline and helps neutralize acids that contribute to tooth decay.
• Bases in toothpaste also help to clean the teeth by removing food particles and plaque.

Information Booster:

• The neutralization of acids in the mouth helps maintain a balanced pH, which is important for the health of teeth and gums.
• Toothpaste often contains a variety of other components, such as abrasives, fluoride, and detergents, but the presence of bases plays a key role in counteracting acidity.

Additional Knowledge:

• Option B: Halogens: Halogens are not typically used in toothpaste for this purpose. Fluorine, a halogen, is used in fluoride compounds to help strengthen enamel, but halogens are not directly involved in neutralizing acids.
• Option C: Acids: Acids would increase acidity, which could lead to tooth decay rather than preventing it.
• Option D: Salts: While salts are present in toothpaste for other functions, they are not the primary ingredient for neutralizing acids to prevent tooth decay.
