Bad Taste in Mouth after Tooth Extraction: Foul Taste after Root Canal

Bad Taste in Mouth after Wisdom Tooth Removal

Tooth extraction can cause a bad taste in the mouth.

  • Right after tooth extraction, there is an open wound on the place where the tooth had been, of course. This open area can easily become the breeding ground for bacteria. When infection occurs, bad taste could be tasted at the back of the throat or on the tongue. However, those who drink antibacterial medication or those with a very good immune system have lesser chances of developing an infection.
  • Another very common side effect of tooth extraction is the dry socket.
    In the normal healing process, blood clots form on top of the extracted area to seal it and hasten healing. In a dry socket, the blood clots that had formed break off or break down. Because of this, the wound is not sealed and the underlying parts are directly exposed to food particles and air. This could be very painful and cause bad taste in the mouth.
  • Foul taste in mouth after wisdom teeth removal is the same as with other teeth.

Foul Taste in Mouth after Root Canal

  • In a root canal procedure, the infected areas are removed and replaced with dental fillings.
    The crown is then temporarily sealed until the next visit to the clinic. Sometimes, this temporary seal can fall off, leaving a bad taste in the mouth.
  • Thus, it is important to keep the temporary crown in place. As much as possible, avoid hard food and substances – meat, ice, and nuts. It is also good to avoid sticky foods such as gum.

How to Get Rid of Bad Taste after Tooth Extraction

  • Eating vegetables and fruits can help remove the bad taste.
  • Brushing, flossing, and gargling can also help. Just make sure that the top portion of the extracted area or root canalled tooth will remain intact.

    Had done radiation for my tongue cancer in 1999. Last October had molar and wisdom tooth removed due to jaw fracture. No pain minor blood seepage. Developed some scabby taste in mouth around 2 weeks ago. Cavity looks healthy but is filling in very slowly. Suggestions welcome

    I just had my lower moral extracted after having a root canal treatment that resulted in a cracked tooth. The oral surgeon had a hard time extracting one of the three roots from tooth#30. The result was that tooth #29, which has also had a root canal and perm crown, fell out because the surgeon drilled deep into the gums and bone to extract a root. Now I am afraid of losing tooth #29 from the extraction and have loss hope for a successful implant on tooth #30. There was a good amount of gum tissue and bone drilled away in the area of tooth #29 which is causing lot of pain. My gums hurt and are very inflamed after four weeks should I be worried?
