Mouth Diseases

Mouth redness

07/13/2006

Question:

I noticed that there is a redness extending from the vermillion border of my lips, mainly the bottom lip, and only a little bit on the top corners of the lip. I was prescribed an antibiotic but it did not seem to work. It also seems that it is irritated when I eat(gets even more red) but seems not to be a food allergy because it happens with pretty much all foods.

Also I have always gotten red when I drink alcohol, so since there is already an irritation, it seems to get redder because of my complextion when i drink alcohol, however I do not think it is related to the alcohol because it is not always true. I have been to the allergist to have the patchtest but I have no known contact allergies.

What could it be, maybe an infection? My dermatolist was not so helpful, so I am going to see an oral pathologist but wanted some background before I go in. Thanks

Answer:

Most cases of redness around the mouth are due to yeast infection that becomes established because this area is kept moist, either by constant licking (consciously or unconsciously) by the patient or by use of petrolatum ("Vaseline") type compounds on the skin.

Occasionally this represents a contact stomatitis (allergy), usually to artificial flavoring agents in toothpaste or mouthwash.  Such localized allergic reactions often do not show up with patch testing, and elimination of the potential offending agent for a week or so is necessary.  If the redness clears up, then returns quickly after the product is used again, this would be evidence of an allergic reaction.

Hopefully your oral pathologist will be able to sort out these problems, but from personal experience, lip disorders can be challenging.
