Why Do We Need Root Canals?

What have you heard about root canals? Over the years, many people have heard inaccurate rumors about this procedure, leading to anxiety or patients avoiding the procedure completely. In reality, this procedure is comparable to a filling placement and can protect the integrity of your tooth. Why do we need root canals?

Rochester, MN Root Canal Quiz

  1. True or False: A tooth can develop an infection.
  2. True or False: A toothache may be a warning sign.
  3. True or False: A root canal can address the issue.
  4. True or False: We complete the procedure with a crown.

Answer Key

  1. True. When the enamel coating our teeth becomes compromised, whether due to poor oral hygiene or injury, bacteria can reach the layers of dentin beneath the surface. A cavity will then form, which will spread until the bacteria reaches the pulp and causes an infection. An infected tooth can lead to uncomfortable symptoms and even endanger surrounding teeth.
  2. True. Tooth sensitivity to hot or cold temperatures or a persistent toothache may be potential warning signs of a dental infection or abscess. Instead of ignoring the symptoms we recommend seeing a dentist to find out if a root canal is necessary to treat the tooth.
  3. True. With a root canal, we open a tooth in order to remove infected tissue. We then thoroughly clean and disinfect the interior of the tooth. After filling the tooth with a restorative material, we place a dental crown to complete the treatment.
  4. True. The crown protects the remaining tooth structure and prevents further infection. We use lifelike materials to ensure the repaired tooth blends with the rest of the patient’s smile.
