 7 warning signs that indicate it's time for you to get a "Root Canal Treatment”
      Root Canal Treatment is the last resort that helps save a natural tooth that is severely infected or injured, preventing the need for extraction. If you neglect these symptoms, the infection could spread to the jawbone, or you might permanently lose that tooth. Therefore, observation and prompt consultation with a dentist when warning signs appear are crucial.

Here are 7 warning signs that indicate it's time for you to get a "Root Canal Treatment."

  • Severe and Chronic Tooth Pain : You have continuous pain that does not go away on its own. It may hurt upon touch or radiate to the jaw and ear, especially pain that disrupts sleep.
  • Abnormally Prolonged Tooth Sensitivity : Experiencing intense and long-lasting sensitivity (more than 30 seconds) when consuming very hot or cold foods, which indicates that the dental nerve has been damaged.
  • Swollen Gums or Abscess : Having swelling, redness, or small, pimple-like bumps (Pimple) on the gum near the problematic tooth. This abscess may periodically discharge pus, indicating an infection at the root tip.
  • Tooth Discoloration : The problematic tooth appears darker or greyish, resulting from the death of the tissue in the pulp (Nerve Necrosis).
  • Swelling in the Face/Jaw Area : The infection at the root tip has spread to surrounding tissues, causing noticeable swelling in the face, neck, or jaw area.
  • Pain When Chewing or Touching : Feeling a sharp pain when biting, chewing food, or even touching the tooth with your tongue, which means the inflammation has affected the ligament holding the tooth.
  • Deep Cavity Reaching the Pulp : If a dentist discovers a very deep cavity that has penetrated the dental pulp, accompanied by pain, root canal treatment is the only way to save this tooth.
      If you find yourself having one or more of these dangerous signs, do not delay or self-medicate with painkillers. An infection in the tooth root is a problem that needs to be treated at its source as quickly as possible. Root canal treatment is not as scary as you might think; it is about saving your natural tooth so that it can continue to function for chewing for a long time to come.
