What is a root canal and who needs one?
Sometimes, the blood vessels or nerves can suffer decay or injury. In those cases, a root canal may be necessary. Endodontic treatment or root canal is the treatment of decayed nerves and blood vessels affecting the tooth root. A tooth that requires root canal treatment may form dark lines or patches that may or may not be accompanied by pain.
How to prevent tooth decay:
Tooth decay can be prevented by regular brushing with fluoride toothpaste and flossing between the teeth. Making regular appointments with your dentist can also go a long way towards having and keeping healthy teeth.
