Is a Tooth Filling or Dental Restoration permanent?
Yes, if the restorative protocols are strictly followed. A good dentist prepares the architecture well, uses a right material, optimally cures the dental cement and polishes the ﬁlling ensuring the longevity of the tooth ﬁlling.
What type of Tooth Filling is the best and lasts long?
Ideally Composite restoration or G.I.C tooth ﬁlling do last long. Amalgam is kind of obsolete considering mercury being hazardous and silver getting oxidised.
Should I replace an Amalgam Dental Restoration or Amalgam Filling?
Yes, amalgam ﬁllings were popular in olden days but now they’re obsolete. An amalgam ﬁlling causes mechanical closure of the cavity which with time can loosen up due to oxidation and contraction causing micro-leakage. This in fact will cause secondary decay or infection, hence amalgam ﬁlling should be replaced with Composite or G.I.C Restoration.
