You dentist will decide what type of tooth restoration to apply.
Whether you agree with the use of amalgam or not, what is true is that amalgam restorations release mercury into the human body, that aging amalgam restorations cause fractures in the teeth they are placed and extensive amounts of tooth structure whether decayed or not must be removed in order to guarantee the retention and strength of the amalgam. This was acceptable 20 years ago as that was where technology had taken us. But, with the advances made in dental materials, affordable alternatives like composite restorations must be considered when restoring teeth. Finally, it is each dentist’s obligation as a health care provider to inform her/his patients of the advantages and disadvantages of having composite verses amalgam restorations placed in their mouth as a definitive restoration.
