Bad and rotting teeth

My second baby has bad teeth and the doctor said it was dental caries. What can I do to prevent same from happening to the sister who is just two and half years old?

What your baby has is called dental caries: it results from poor oral hygiene, licking of sugary foods which stick to the gum and form mucous of bacteria: which is an infection.

The steps to take include brushing the mouth twice a day. Avoid anything that will leave food debris in the mouth; especially overnight. Also, take the child for routine dental check up every three to six months.
