Most glue sticks are designed to glue paper and card stock together and are not as strong as some liquid-based variants. They can be used for craft and design, office use, and at school. There are several varieties: permanent,washable, acid-free,non-toxic, solvent-free, and dyed (e.g. to see where the glue is being applied).
Ethylene-vinyl acetate (EVA) copolymers, low-performance, the low-cost and most common material for the glue sticks (e.g., the light amber colored Thermogrip GS51, GS52, and GS53). [9] They provide sufficient strength between 30 °C (86 °F) and 50 °C (122 °F) but are limited to use below 60 °C (140 °F) to 80 °C (176 °F) and have low ...
In addition to brushing, cleaning between teeth may help to prevent build-up of plaque bacteria on the teeth. This may be done with dental floss or interdental brushes.. 80% of cavities occur in the grooves, or pits and fissures, of the chewing surfaces of the teeth, [4] however, there is no evidence currently showing that normal at-home flossing reduces the risk of cavities in these areas.

A 1930s poster from the Work Projects Administration promoting oral hygiene. Tooth decay is the most common global disease. [14] Over 80% of cavities occur inside fissures in teeth where brushing cannot reach food left trapped after eating and saliva and fluoride have no access to neutralize acid and remineralize demineralized teeth, unlike easy-to-clean parts of the tooth, where fewer ...
