What is decay factor?

In mathematics, exponential decay describes the process of reducing an amount by a consistent percentage rate over a period of time. It can be expressed by the formula y=a(1-b)x wherein y is the final amount, a is the original amount, b is the decay factor, and x is the amount of time that has passed.

What is tooth decay and how to prevent it?

Preventing Tooth Decay. Tooth decay is the destruction of tooth structure and can affect both the enamel (the outer coating of the tooth) and the dentin layer of the tooth. Tooth decay occurs when foods containing carbohydrates (sugars and starches), such as breads, cereals, milk, soda, fruits, cakes, or candy are left on the teeth.

These materials would be placed between teeth or in pits and fissures of teeth. Toothpastes and mouth rinses that can reverse and “heal” early cavities are also being studied.
