Good preventative dentist near Brive, Limoges

Does anyone know of a GOOD dentist somewhere near Brive or Limoges who looks at teeth wholistically rather than just looking for current problems?

I have crowns, cracks in some teeth and wear a mouth guard. Because I know my teeth are in constant need of 'help' I really need a preventative-orientated dentist. Please help!

thanks for any advice. I would travel farther than Limoges or Brive for the right dentist...
