Is it normal to need at tooth filling at 18?

Sensitivity to sweets is usually because of tooth decay. The acids from eating sugar irritate the nerves in the tooth because of a cavity. Go to the dentist, you probably need a filling.

Do not wait until it's too late to save your tooth. And FYI if you have a cavity drinking tea is not going to heal it. It will get worse if you don't get it fixed.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
