Thanks so much for all the suggestions - lots there to try
Just on the mouthwash - the cordosyl mouth wash, while can be effective tends to yellow the teeth, (slightly) and has lots of junk, chemical stuff. Especially if a regular tea/coffee or indeed redwine drinker.
Found one in the healthfood shop for anyone interested. "JASON", Healthy mouth. Contains no alcohol, saccharin and tastes so much better and doesnt tend to discolor teeth as much. Different flavours too like aloe vera, tea tree & cinamon.
