  • Your dead tooth may change color from time-to-time which can include; grey, yellow, or even black.
  • Once a tooth starts to die, the dentist will do their best to prevent the spread of further damage. 

Dead Tooth Diagnoses

If you have a dead tooth, you may notice a few different signs that will occur. One of the most obvious signs is discoloration of the tooth. All your teeth may be discolored to a certain degree depending on your dental hygiene habits. A dead tooth will most likely be discolored, even more, they often appear as solid yellow, grey, or even black. If you’re are unsure if the tooth is dead based on its color, a dead tooth will get worse over time and the color will change, depending on how late you noticed the dying tooth.

  • Pain – You may or may not feel pain.
  • A bad taste in your mouth
  • Swelling around your gum line
 
Visiting the dentist is the best way to diagnose a dead tooth, they will have a better understanding of the symptoms and can also take x-rays of the mouth to see inside the tooth.

How do you treat a dead tooth?

A tooth can’t be brought back to life, however, if a tooth dies it is incredibly important to treat the dead tooth to prevent the spread of infection. Typically there are two ways to treat a dead tooth:
 
  • Root canal therapy – The inner pulp and root system is cleared out of the tooth and is usually sealed with a crown.
  • Dental extraction – The entire tooth is removed.
 
Even though there is no way to regain the full health of the dead tooth, preventing the spread of infection is critical to maintaining the health of the remaining oral structures.

If you can’t get the treatment immediately, your tooth might because you pain or discomfort, here are some DIY ways you can mitigate the pain:
 
  • Avoid extreme temperature food or drink – Try to have only lukewarm, slightly warm, or cold food or drink.
  • OTC pain medication – If you’re able, you can take the recommended doses of drugs like Advil or Tylenol.
  • Avoid hard, sticky foods  – These will further damage the tooth, which is already in a weakened state.

  • Good oral hygiene – Brush, floss, and use mouthwash twice a day.
  • Get regular checkups – Your dentist can spot an infection early.
  • Wear a mouth guard – Physical injury can be a huge threat to oral health.
  • Eat a balanced diet – Too much sugar, acidic foods can promote decay.
  • Drink water – Keeps you hydrated, helps your saliva production.
  • Chew sugarless gum – The gum can help re-mineralize your teeth, and remove food particles.
