  14. The hard deposit of mineralized plaque that forms on the crown and/or root of the tooth. Also referred to as tartar.
  15. Hard deposit of mineralized material adhering to crowns and/or roots of teeth.
  16. Hard residue, commonly known as "tarter," that forms on teeth due to inadequate plaque control, often stained yellow or brown
  17. hardened deposit of mineral salts formed around the teeth.
  18. The sticky film on your teeth (plaque) that has hardened. Also known as tartar.

  20. Same as tartar. Occurs when plaque is left on the teeth untreated. A hard substance that acts an irritant by wedging between the tooth and gum. Left untreated calculus can eventually lead to periodontal disease.
  21. Also called tartar. A tenacious, hardened material formed by mineralization (calcification) of dental plaque, which once formed can only be removed by a dentist/hygienist.
  22. A sticky substance (also called tartar) that has hardened.
