Amazinyo, njengawo onke amanye amalungu omzimba womntu, aphantsi kotshintsho olunxulumene nobudala. Ke, kwiimeko ezininzi, ukutyhubela iminyaka, amazinyo amnyama. Oku kwenzeka ngenxa yezizathu ezininzi. Okokuqala, ngenxa yokuthoba i-suble ephezulu yezinyo - i-enamel. Ukusuka kwixesha lokudibana nexesha, i-enamel ijika ibe yifilimu "ebonakalayo", apho ityheli, ngwevu okanye i-Dentin ebomvu ibonakala.
Okwesibini, izinto zangaphandle zichaphazela utshintsho kumbala wamazinyo. Oku kubandakanya isiyobisi kwiti, ikofu, ukutshaya kwaye ungakhathali ngokwaneleyo amazinyo.

Akukho mntwana wolutsha unokungqina ubude bamazinyo aqhuba ngexesha lokuphila. Oku kukhokelela kutshintsho kwi-Bite kunye nobuso obuvaliweyo. Ngethamsanqa, oogqirha bamazinyo bafundile indlela yokujongana nale ngokunyusa amazinyo okanye ufakelo lweevene.
Ukungabikho kwamanye amazinyo nawonakalisa uncumo. Kwenzeka nokuba amazinyo angasemva alahlekile. Ngenxa yezithuba ezikwi-dection, amazinyo aseleyo atshintsha isikhundla sabo (izithuba ze-Instersuble, i-curvature yamazinyo ivela). Ke ngoko, kufuneka ubhenele kwi-prosthetics ngendlela yexesha elifanelekileyo.
