I have lost a filling.
ot-tu-ra-TSYO-ne — five syllables. Double 't', then 'z' sound for 'zi'. Stress on fourth syllable.
Report this as soon as it happens — call the dentist immediately. A lost filling exposes sensitive dentin and can get worse quickly.
'Ho perso' is the passato prossimo of 'perdere' (to lose). 'Un'otturazione' is a filling — the vowel elision ('un'' instead of 'una') happens because 'otturazione' starts with a vowel. Alternative terms: 'piombatura' (older term) or just 'la chiusura del dente'.
Mi si è staccata una corona.
My crown came off.
'Corona' is a dental crown — staccata = detached/fell off
Ho perso il ponte.
I lost my bridge.
Dental bridge — 'ponte' literally means bridge
Si è rotta la mia protesi.
My denture broke.
'Protesi' = dental prosthetic/denture — common in older patients
In Italy, dental fillings ('otturazioni') are done with composite resin ('resina composita') for visible teeth and amalgam or resin for back teeth. Amalgam fillings are being phased out under EU directive. Composite fillings are tooth-coloured and have become standard. Emergency temporary fillings can be done immediately, with permanent ones at a follow-up.
