A sinus infection is one possible cause.  (A very large part of the sense of taste relies on the sense of smell).  Zinc or B-12 deficiencies can also cause loss of sense of taste.  Many other possible causes are given in the link below.\n\nThe condition is known as dysgeusia.

We feel the taste because there are ionic channels in the membrane of taste cells. Ionic channels are proteins which activate with stimulus like acid, warm, cool, etc. The main function of these ionic channels in the taste cells are to sense taste, but they can be sensible to temperature as well, so fever could give you an illusion of bitter taste because the activation of such a channel by temperature and not by any bitter substance.

Stop smoking or drinking coffee, and when you brush your teeth, also brush your gums and tongue.  Make sure you eat a balanced diet (not too much meat, which can sit in your stomach, and cause the odor to come up your esophagus and into your mouth.)  Also try "breath assure" which is a caplet you swallow, and it releases freshness into your mouth all day!

I would give up the sense of taste.  It seems the least important to my everyday life.  I certainly couldn't get through the day normally without my sight, hearing or sense of touch and I wouldn't be able to smell potentially harmful substances without my sense of smell.

Yes there can be changes in taste and smell and in the total person, after heart surgery. Doctors are finding more evidence of this till they actually are expecting it from anyone who has heart surgery. But some cases find that their taste or smell will be ok in about 2 yrs or more. I have read it has something to do with medications reacting on the brain, wheile asleep for surgery. From experience i find that you actuall fully return to normal in about 5 yrs, diffrent people vary.

My friend lost her sense of smell due to a head injury, she can't taste anything.  There actually is a medical term for this but I can't remember what it is.  She has gained alot of weight since her injury.  She's constantly eating just TRYING to taste something and of course NOTHING satisfies her, hence, the weight gain. If you or someone you know can't smell, be sure and warn them about having smoke detectors in their home and that the batteries are good.  It's vital, since the smoke won't be smelled.

Sounds like more than a single punch.  Taste and  sensations about the face come from small cranial nerves which may have been jarred or damaged.  A broken bone is not what you should be concerned about.  You need to see a doctor.
