- WHY OUR TEETH DECAYS??
- WHEN PH IN OUR MOUTH FALLS BELOW 5.5 , THEN OUR TOOTHS STARTS DECAYING .TOOTHBRUSH PREVENTS TOOTH DECAYING AS IT IS A BASE WHICH NEUTRALISES THE ACID IN OUR MOUTH .

- WHEN ACID AND BASE REACTS TO FORM H20+ SALT AND INVOLVES COMBINATION OFH+ OH- TO GENERATE WATERTHIS IS NEUTRALISATION REACTION
