Kwinkqubo yokwenziwa kwemilomo yemilomo, into yokugqibela esifuna ukuyiva sisiphithiphithi, kuba uninzi loqhwithela alulawuleki, oluya kuchaphazela ifuthe lokutshiza kwemilomo yethu. Kwiminyaka emininzi yokujongana nesiphithiphithi, sishwankathele iseti yezisombululo ezisebenzayo kuxinzelelo. Okokuqala, okufanelekileyo kakhulu kukufaka iincakuba zentsimbi ngaphakathi kumbhobho okanye kwisihlalo esinyukayo semibhobho, esinokusombulula imeko yovalo ngokufanelekileyo.

Isiphithiphithi sidalwa kukungahambi kakuhle kolwelo kumbhobho, ngakumbi kwimida yeengqiniba, iti, njl njl. ukuhamba ngokuthe ngqo, ukuze kube lula ukufumana ukuhamba kwe-laminar. Ukuba iimeko zofakelo azivumeli, unokusebenzisa umlomo wethu wokuchasana nengxabano okanye isiseko semilomo yokulwa nengxabano.
