Caries which recurs beneath a previously restored tooth are known as secondary caries. These are also known as recurrent caries. These are common with composite restorations. Any micro gap in the tooth restoration margin causes a local collection of food debris and bacteria, leading to caries in the long run. Removal of the initial restoration along with caries and re-restoration helps. These are mostly diagnosed through patient's symptoms or dental X-rays.
