Fortunately, Root Canal Retreatment may help remove persistent infection and give your natural tooth another chance. Learn why root canals can fail, the warning signs to watch for, and how modern retreatment techniques at Dr Deval Mehta™ can help save your tooth.

Gum Infection or Tooth Infection: How to Tell the Difference can be confusing because both conditions may cause pain, swelling, and sensitivity.
