​Decay often starts from most vulnerable part of the tooth like the grooves and pits on the top surfac​e. The pits and grooves are opened and cleaned using very fine instruments.

​Modern dental materials allow us to be very minimally invasive when it comes to cleaning cavities. We no longer rely on mechanical retention of fi​llings and hence do not need to remove healthy tooth structure unnecessarily.

​Modern dental materials are capable of sealing the teeth effectively minimising bacterial ingress into the tooth. Some of the materials have therapeutic properties as well  and are able to "re-mineralise" the effected dentine.
