Caries are bacteria that can occur in situations of poor oral hygiene or a lowering of the immune system. Often people do not notice their presence; only later their presence is manifested due to the pain they cause. For this reason it is important, in addition to good oral hygiene, a regular inspection by your dentist.
When the caries is located, the dentist will proceed to its removal and subsequent reconstruction of the part of the tooth that is compromised.
