Tooth restoration: removing the caries and filling the tooth with filling materials like composite or amalgam is an important way to prevent future aggressive treatments like root canal treatment. If tooth caries is detected early, the treatment would be much easier and even more economic for the patient. Actually tooth caries is a microbial disease and removing the caries actually removes caries-associated bacteria and by this way the oral environment will be improved and caries associated bacteria are not transferred to other healthy teeth.
