What is the difference between tooth decay and a cavity?

Q.
I have been told that one of my teeth has tooth decay and that I will need some treatment to help make sure it does not get any worse. What I would like to know is what the difference between tooth decay and a cavity? or are they just the same?
A.
hi many thanks for your email, decay is bacteria eating away at the hard tooth tissue makingit soft and brown. a cavity is a decayed area of tooth which then turns into a hole.
