Plaque is a colorless residue that builds up on the teeth. It contains microorganism that may cause tooth decay because of the bacteria present and it is the major cause of gum diseases.
Parents should be the one to guide children in constant cleaning of teeth. Teaching them to floss regularly will prevent inflammation of gums. Toddlers kids are to young too do this so it is best that you do the flossing for them. Because the primary cause of gum disease is the build up of plaque, we have to be aware of the plaque forming substances which allow bacterial growth inside the mouth. Some child habits like thumb sucking (which must be avoided) may displace teeth will also make harder to remove plaque as well as crooked teeth.
