I think Lidl was flogging summat like this a week or so back!
My dentist suggested I mouthwash with Miltons. We used this stuff for the penultimate clean on our kids 'proper' nappies, but apparently after not a lot of research it seems that Miltons was first produced as a, er, mouthwash!
So that's the new regime:
Brush 'n mouthwash
Brush, floss
Weekly, swill a bit of diluted bleach round yer gob!
