DermTV – The Difference Between Canker Sores and Herpes [DermTV.com Epi #103]

October 19, 2019


[music]
Hello, I’m Dr. Neal Schultz [pause] and welcome to DermTV. When we get sores inside our mouth or on our
lips, usually they’re very painful. And almost all of them are caused
by one of two things—either a herpes virus outbreak or canker sores, and
I find that not only do most people get them confused, but can you believe
this, most doctors get them confused also. So let’s talk about it. Canker sores are not contagious. They’re
very painful, especially when you’re eating and food touches the area
where you have the canker sore. Canker sores occur almost exclusively inside
you mouth, not outside, not on your outer lip, and not on your chin. And
when they occur inside your mouth, which can be on this part of the skin
or seen inside the cheeks, you see a gray or tan, round area with a bright
red rim right around it. They go away in a couple of days and they’re
easily treated with topical antibiotics. Usually, we take tetracycline,
open a capsule, put it in a little glass of water, and take just a piece
of cotton, dip it in that water, and hold it against the canker sore
for a few minutes and, after 2 of 3 days, it will go away. This is very,
very different from herpes outbreaks. Herpes outbreaks usually are not
that painful although right before you get them, you feel a tingling or
a burning in the skin where you’re going to get the outbreak. They are
very contagious. They usually don’t occur inside your mouth, they occur
outside your mouth. They can be right on the lip, on the edge of the lip,
or around the mouth, or really any place on your face. And when they happen,
usually they occur with blisters, and those blisters are often clustered
together and with a red ear around it but not a red, sharp rim like
you see with a canker sore. Over a period of a couple of days, they dry
and crust and scab. They’re very easy to treat. They’re treated with
oral medication, oral medication for only a day may become not contagious by
the second or third day. If you’re getting sore inside your mouth or
around your mouth or on your lips, and you’re not sure what it is and you don’t
know how to treat it, see your dermatologist who can give you some medicine
to make sure that the sores go away faster and you become comfortable much
sooner.

    I get canker sores more often than most people.. I find that really keeping my mouth clean, brushing, flossing, and using mouthwash will really help to make them go away faster. The mouthwash also seems to alleviate the pain for a small period of time.

    The non prescription way to kill a Kanker sore is Listerene. Force it into the sore and hold it there. May have to repeat a few times. It burns like heck but it'll kill it. For a script I get from the skin doc or my dentist, I use Treamcinolone Acetonide nick name is easier, "dental paste". It works fast!

    Thanks for this video. My 2 year son just got a mouth full of canker sores after running a temp and hasn't been able to eat well for almost 3 days now. I took him to an urgent care Dr.yesterday and he was clearly misdiagnosed. They are treating him for Strep (no results from test). I am wondering if Omnicef (liquid) will help these go away like the tetracycline? This is the antibiotic they gave me.

    Hey let me increase your education. For those of you who don't know, THERE ARE DIFFERENT HERPES. The one in this video isn't from having sex. You can easily get them from kissing, sharing drinks, lip balm, etc. you're thinking of genital herpes, which is completely different. YES YOU CAN GET MOUTH HERPES AND BE A VIRGIN. It's a form of herpes but no it is not an std. If you have ever heard of a cold sore, that's herpes. It's not bad. You don't need to worry thinking you slept with the wrong person and they gave you herpes. Increase your education people

    "Cold sore" is a common term for a herpes blister.  However, growing up, my parents called canker sores, cold sores.  They didn't know the difference either.  I get canker sores infrequently (silver nitrate caustic pencils are awesome for these) but have never had a cold sore/herpes blister.

    If it is herpes, go to the doctor. But for all other penis skin issues, use a creme called Man1 Man Oil. It is made just for the penis skin and will keep it moisturized, clean and irritation-free if you use it once a day. It is an awesome product. Check it out.
