King, there are studies showing negative effects of fluoride. A search gives me this and this, both of which point out that too much fluoride increases the risk of fluorosis and too little increases the risk of tooth decay.
In this thread Julian pointed out to me that most of the UK does not have as much fluoride in the water as is recommended by the world health organisation. [quote=“Julian, post:14, topic:1788”]
@Quidditch where did you get the info from that said “Most parts of the UK either have this level naturally or add it to the water”.
According to this page virtually no areas of the UK have 1.5mg per litre.

So it might be a good idea to get more fluoride from somewhere.
To whoever posts next, please could we keep it civil. Your post can be well mannered even if that makes it the odd one out.
