HELLO SIR...
Human tooth crown portion has three parts ENAMEL,DENTINE, PULP..
IF THE CARIES IS IN ENAMEL AND DENTINE You can restore the tooth by simple filling...if the caries reaches the pulp (contains nerves and blood vessels) you will have the symptom of pain and you need to go for ROOT CANAL TREATMENT followed by capping of the tooth..
Root canal treatment is a conservative procedure which will restore the tooth which cant restore with simple filling...
