Names of teeth
Other useful words
Gingival = Gums
Plaque = a sticky film of bacteria that constantly forms on teeth and along the gumline
Calculus = if plaque is not removed, it can harden over a few days and turn into calculus (tartar is another word for calculus). Calculus is a bit like scale in a kettle and over time can cause gum disease.
Bite wings = small x-rays that allow to look at the surfaces where the teeth meet each other (used to look for checking for cavities)
OPG = Large full head x-ray that shows your bone levels and the pathology of your mouth (not very useful for checking for cavities, but good for seeing if gum disease has affected bone levels)
PA = small x-rays that focus on one or two teeth in particular
Composite = Tooth-coloured filling material
Amalgam = Silver filling material
