What Causes Acidity In Mouth And Yellow Discoloration Of Teeth?

I have always taken good care of my teeth but for almost a year now there has been a severe increment in the acidity in my mouth, accompanied by relatively sudden yellowing of my teeth. X-rays have revealed recession of the bony support of my lower incisors, resulting in sub-gum pockets, repositories of bacterial "cesspools". My dentist attributes the bony recession to trauma, possibly the fractured jaw I suffered playing rugby at St. Amdrews U over 40 years ago. Last year I went on a 670km charity bicycle ride in India and was knocked off by a motorised tricycle on the first day. Though protected by a helmet, my head hit the tarmac with quite an impact -- more trauma? Also I was silly enough to take chai at roadside cafes. Goodness knows what bacteria I may have ingested! Is there any way I can put an end to this discomfort?



Yours faithfully,
