L'erosione dello smalto e l'ipersensibilità dei denti hanno portato all'immissione sul mercato di dentifrici sviluppati per combattere questi problemi, ma su nove prodotti analizzati da una ricerca condotta dall'Università di Berna, nessuno si è dimostrato in grado di mitigare la perdita superficiale dello smalto.
Per combattere l'erosione dentale, sottolineano i ricercatori, sono necessari una terapia specifica, un dentifricio adeguato e soprattutto un cambiamento della dieta.
Cibi e bevande, afferma uno degli esperti, sono infatti sempre più acidi a causa della lavorazione industriale. Un ambiente più acido associato alla spazzolatura porta a una maggiore erosione dello smalto.
