Question

Dental floss removes plaque from areas your toothbrush just can’t reach. Unremoved plaque can build up between teeth and around the gum line, causing gum irritation and tooth decay. Floss comes in both waxed and unwaxed varieties. Both are effective, but if you have tightly spaced teeth, waxed floss may be easier to use.

(Good Housekeeping, November 2014, page 112).



To build up – acumular, concentrar.

Gum – gengiva.

Decay – deteriorização.

Wax – uma substancia feita de gordura ou óleo.

– dentes.
