Dental filling is a procedure adapted to restore functions of the decayed tooth to normal. Dental research has progressed from time to time in developing new techniques to find an alternative to mainly dental filling to avoid the use of composite resins which discolour over time and amalgam fillings which are alloys of metals with minute quantities of mercury.
According to The Washington Post, researchers at Kings College London developed new technique which may antiquate the process of dental filling.
Dental Research during the past few years resulted in developing a technique that uses low frequency electrical currents to stimulate self healing of the decayed tooth called as ‘electrically accelerated and enhanced remineralization’.
This procedure will be available in dentist’s office in two to three years. It is based on remineralization by stimulation which is a painless method and heals the tooth naturally.
