Sugar is the main cause of decay and it is found in many of the foods we eat and drink either naturally or as an additive.
Poor Oral Hygiene as well as weak tooth structure can also be factors in tooth decay.
Bacteria that have settled on a tooth feed on sugar. They multiply themselves so that there areeven more of them, the bad news is when bacteria and sugar get together a chemical reaction occurs that produces acid which eats away at the enamel of the tooth. The more sugar we eat results in more bacteria which produces more acid which increases the chance of decay.
Fluoride helps strengthen tooth enamel making it harder for the acid to eat its way into the tooth but once the decay process has started it accelerates at a rapid rate. After eating through the enamel the decay then attacks the softer dentine. If left untreated, the decay will consume the tooth eating its way further down to the nerve, ouch!
It is therefore important to try and limit the amount of sweet foods and drink that we consume and to brush our teeth shortly after every meal – including lunch.
