What causes cold sores in the mouth?

Answer 1

There's a difference between a cold sore and a mouth ulcer. A cold sore usually is outside the mouth, on the lips, and is caused by a strain of the herpes virus (the same one that gives chicken pox). A mouth ulcer is a little sore inside the mouth. I get them when I have something with too much acid. Tomatoes cause them and drinking too much orange juice or other citrus juices. I think it can be different for each person on that, but I have read that the acid seems to irritate the lining of the mouth to produce them. For me, if I stop whatever acid is causing it, then they go away. Sometimes they can happen when you accidentally bite the inside of your mouth.

Sometimes it can be a deficiency of Vitamin C

For many years people have lived under the belief that the cause of cold sores is a cold or flu. In more recent years, studies have shown the actual cause of cold sores is linked to an infection of the mouth with herpes simplex virus that is the cause of cold sores. Cold sores are small fluid-filled sores develop on the skin, lips, or mouth in single or multiple clusters. The cause of cold sores is simply lack of knowledge about a virus that is contagious and has little to do with colds or flu’s. Though the symptoms that are associated with an outbreak of cold sores may be similar to that of a cold or flu, the virus that is the cause of cold sores differs greatly from that of the common cold.

The first eruption of sores due to infection with oral herpes simplex virus is called primary herpes. Cold sores are usually contracted in childhood. Primary herpes may be mild or severe, but it often affects large areas of the mouth and always the gums. Any subsequent eruption of the sores is called secondary herpes. Secondary herpes is a reactivation of the virus rather than a new infection. There are at least two forms of herpes simplex virus. In the past, herpes simplex virus type 1 was believed to be the only cause of cold sores above the waist, and type 2 was the believed to be the cause of sores below the waist (genital herpes). Now, however, either type is known to be the cause of cold sores anywhere on the body. Herpes simplex virus type 2 tends to be more severe than type 1.
The most common cause of cold sores is when a previously uninfected child acquires the virus from contact with an adult who has a cold sore. In rare cases, a person first acquires herpes simplex virus in adulthood, also after contact with someone with a cold sore.
The cause of cold sores is the ability to spread the infection from the time the tingling sensation that precedes the development of a sore the prodrome is experienced to the time at which the sore has completely crusted over. It has not been confirmed through studies that sharing a glass or touching something that an infected person has touched may spread herpes.

When primary herpes is acquired in childhood, the infection causes gum inflammation and extensive mouth soreness and causes cold sores. Fever, swollen lymph nodes in the neck, and general discomfort may develop. A child may be cranky and cry continually. However, many cases are mild and go unrecognized. Parents often mistake the problem for teething or another illness. In more severe cases, small blisters form in the child's mouth. These blisters may not be noticed because they rupture within a day or two, leaving many ulcers. The ulcers may occur anywhere in the mouth but always include the gums. Though the child gets better in a week to 10 days, the herpes simplex virus never leaves the body.

When primary herpes is acquired in adulthood, symptoms are usually more severe and include multiple rapidly developing painful sores on the gums and other parts of the mouth.

Unlike primary herpes, the more widespread cause of cold sores and mouth soreness, the flare-ups of secondary herpes usually produce a single raw, weeping open sore on the outer lip that later crusts over before healing within two or three weeks. The sore is sometimes called a cold sore or fever blister. Less commonly, a cluster of blisters forms on the roof of the mouth. These small blisters run together and quickly break down into a sore. There is no crusting stage.

Flare-ups are often triggered by sunburn on the lips, certain foods, anxiety, a cold (hence the name "cold sore"), fever, or anything that lowers the body's resistance to infection. Certain dental procedures can cause a flare-up as well; if a cold sore already exists, dental visits should be postponed until the sore heals.

Depends. Herpes simplex 1 virus is the most common cause. HS2 causes the sores you need Valtrex for. But you can get HS2 on your mouth if you do oral.

Answer 7

It's herpes. Someone has to give it to you but the cold sore herpes virus can be passed to you by drinking after someone who has a cold sore. Once you've got one, your stuck with it. :( My friend takes an oral herpes medication, and also uses abreva. She gets them pretty bad.
