My 3 yrs old child started to get tooth decay badly.. I noticed black dot in upper front 4 teeth at 2 yrs. he was breast fed till 2 yrs. since then I'm brushing his teeth regularly and no bottles at night at present. Suddenly I noticed decay getting worse.consulted doc he said to avoid chocolate and bottles.. which I'm already doing.. but still worse my questions What ways to control? What paste to use? He constantly gets itchy skin is it because of decay? This really making me to worry
