Good question- I once had a little 4 year old girl I was treating in Cardiff Dental Hospital and every time I said "OK so we need to do XYZ" she would say "Why?" and it didn’t matter how many times I answered, her response was always "Why?" After my fourth ‘why’ explanation, the mother said "She’s not actually listening to you- she just likes the word"- which made me laugh.
What's my point.. well, I am sure my answers were useful for the mother in understanding the reasons behind what we were doing. If you understand the reasons behind doing something, it makes actually remembering what to do much easier (because it just makes sense) and the argument for doing it so much more compelling because you know what will happen if you don't.
For that reason, understanding what really happens in tooth decay is so important. The following links explain it clearly and simply:
