Decaying food particles in your teeth produce acids and cause tooth decay. It is a neutralization reaction that prevents tooth decay. Toothpaste is an alkaline that cancels the acidity that may have accumulated on your teeth after you have eaten.
In this topic, you learned that neutralization is the process in which an acid and a base cancel each other. The reaction will create products that are easily predictable, as most of the reactions are double-displacement reactions. One of the most important products that is created during a neutralization reaction is water. Also, if either carbonate or hydrogen carbonate are products, you must treat these reactions as decomposition, producing carbon dioxide and water.
