Question

explain tooth decay and diarrhoea​

Answer 1

Tooth decay occurs when foods containing carbohydrates become trapped between teeth and are not completely removed with brushing and flossing. The plaque bacteria generate acidic by-products that eat away at the tooth enamel, slowly creating holes in the teeth called cavities. Without treatment, these holes can grow larger over time and may even destroy the whole tooth

Answer 2

Tooth decay occurs when bacteria in the mouth leave acidic plaque on the teeth, which corrodes the enamel, dentin, and eventually pulp of the tooth. 

diarrhoea:material (faeces)from your body very often and in a more liquid form than usual
