Q. Hi i have a constant build up of tartar on the front bottom teeth and it gathers in a slightly recessed gum even after one day, also notice bad tasting mouth within an hour of a good brush and mouth rinse. was thinking of purchasing a ionic toothbrush as a start, also my dentist said to brush the problem area in a clockwise circular motions to remove tartar but does not really help. also find it hard flossing the back teeth, when i do they normally bleed and smell quite bad probably the food debris etc. thanks
