Usage: Impaction is an unerupted or partially erupted tooth that does not fully emerge because it is blocked by another tooth, bone, or soft tissue.
Lay term: Spit

Usage: Fluorapatite forms a stronger crystalline lattice than hydroxyapatite, making teeth more resistant to decay.
Definition: Adjustment of the level of fluoride in a public water supply so that the community receives the maximum benefit without side effects.
Usage: Because water fluoridation has the advantages of equity, distribution, compliance, and cost-effectiveness over other fluoride-delivering methods, it remains the fundamental base for caries prevention in many communities.
Definition: A naturally occurring inorganic ion of fluorine which renders teeth less susceptible to dental decay that is most effective in children and younger adults. It is also used in older adults to prevent root caries.
Usage: Fluoride may be added to dentifrice, mouth rinses, and water supplies where it does not occur naturally, and applied topically by dentists.
Alternate term: Enamel hypoplasia
