Any dentists? Have any tips on improving enamel?

[Teeh]

One of my dc has weak enamel. I think it is more due to nature than due to bad habits. We are doing everything to try to protect the enamel that is there.

are tooth mousse any good? Or any particular toothpaste likely to help at all?

also should he brush before or after breakfast as we get conflicting information on this

Brush before breakfast so you're not giving the bacteria anything to feed on
Duraphat toothpaste is high fluoride, I get it on prescription
Don't rinse with water or mouthwash
