If i get a cut/abrasion on my tongue from broken tooth, are there any bacteria or microorganisms in my mouth that could cause severe tongue swelling?

Yes: The mouth contains abundant bacteria and a break in the skin can cause infection. Antibiotics generally work, in addition to good oral hygiene. All the best.

Aerobes+anaerobes: Human bites are the worst kind in regards to secondary infections. Yes, a cut could become secondarily infected and cause swelling of the tongue. If that is the case, best to have it looked at in an urgent care clinic where an antibiotic can be prescribed if necessary. Try ice water for swelling reduction in the meantime.

Sure: The human mouth has many bacteria in it. A laceration on your tongue will naturally swell a little as an inflammatory reaction around the site of you bite. If thi swelling is bigger than normal, you are experiencing pain and even possible pus form the sit, it may be infected...which in that case you need to see your Dr for an examination and possible antibiotic treatment. Good luck.

Tongue swelling : A repeated abrasion to the tongue from a broken tooth could cause swelling on its own. There is a normal micro environment of bacteria and yeast in everyone's mouth. Your immune system should prevent a pathogenic bacteria or yeast from taking over, but it is possible. If it is progressively worsening, you should get seen by MD and a culture obtained of drainage. Sometimes a biopsy is needed.
