Geographic tongue or Benign Migratory Glossitis, BGM

As an oral condition, a geographic tongue can turn tongue colour and normal texture. Basically, a geographic tongue is characterized by inflammation of the tongue including the papillae or taste buds. This inflammation is what is referred to as glossitis. However, it does not make the tongue look bumpy.

What can help one know it is geographic tongue? This condition is also characterized by smooth, red or pink spots and sometimes reddish patches/blotches with white borders. Depending on the affected regions of the tongue, the signs shown by presence of the patches may shift or “migrate’ from one point on your tongue to another. Although it is considered harmless, people who are affected suffer from soreness and feeling of pain on tongue brought about by the effects of taking hot meals and spicy foods.

BGM can cause much discomfort in addition to suffering caused when taking hot or spicy foods – especially if you have tongue sores such as those that form after biting,.

In order to get rid of the symptoms due to a geographic tongue, a careful diagnosis should be done by a professional or oral dentist. Furthermore, the problem could be solved by prescription of topical medicines after diagnosis and evaluation.


Can infections lead to formation of red spots or red tongue in appearance? While pain, bleeding, white spots, abnormal tongue coating, bad breath, et cetera could be all symptoms of oral infection; what do red spots signify?

i.                     Hand, foot and mouth disease

To begin, this illness is caused by a various viruses. As a disease affecting majority of the young children, hand, foot and mouth disease can affect both young adults and grownups particularly during the weather conditions of the summer, spring and fall.

A careful study of the symptoms can reveal that presence of painful sores in mouth that begin as flat red spots (not raised) are due to this disease. According to an article published by Centers of Disease Control and Prevention, CDC, other symptoms and observable signs include:

  • Sore throat,
  • A sickish or feeling sick,
  • Fever,
  • Reduced appetite,
  • A rash marked by red spots. These spots form blister-like spots typically on palms and bottom of feet.
  • Presence of “painful blisters and red spots on the roof of the mouth,” [colgate.com] on hands and feet as well.

Like most human viral diseases, this infection can spread from one infected individual or source of infection to the other especially in the first week of infection. Modes of transmission could be air, fluids or when one comes into contact with the virus and then the virus enters the body. This implies that anyone is at risk though children are easily victimized.

ii.                   Scarlet fever

Scarlet fever is the other infection which can turn the tongue meaning that it appears red and swollen or bumpy. This infection is due to bacteria. Just like hand, foot and mouth disease, scarlet fever is contagious too (the bacteria can be transmitted from an infected person) but there are medicines that will help clear its symptoms.

Canker sores

Canker sores are not contagious but studies have shown that they may appear as red sores anywhere in the mouth which includes the inner cheeks, on gums, tongue and under tongue. According to Healcure.org, these red spots are due to cancer sores if they have yellow or white center and a red ring surrounding it.

Generally, canker sores may be termed as being complex or simple. Those complex ones are thought to be caused by certain complex health conditions, diseases like Crohn’s disease or problems arising from nutrition such as iron deficiency. On the other hand, the simple canker sores may appear “three or four times a year and last up to a week.” [wemd.com] and are common in young people mostly those in the teens.

Canker sores can cause painful mouth lesions but the pain could be even more painful than cold sores if a person has a weakened immunity or is infected with HIV.


Moving on, smallpox was a scare, concern and health emergency to any nation before it was wiped out of the face of the world through vaccination programs. Perhaps it would be deadly assuming that it would be in existence.

What is the real concern or what was the scare? Any individual reported with smallpox is “sometimes contagious when they get a fever, but the person becomes most contagious when they get a rash.” [emergency.cdc.gov].

What does this mean therefore? After its outbreak an infected person already bears the virus but may not show the symptoms and thus smallpox may not spread. After a certain period of time (a few more days) symptoms usually surface. They include:

  • A red rash on tongue and in mouth,
  • High fever,
  • The rash becomes small raised bumps after which it disappears in the second week,
  • Pustules that result from the bumps. These pustules eventually form scabs on skin.

Inflamed tongue papillae

Do you find or get small bumps after a hot meal? That is what is likely to be experienced as any form of heat easily irritates the tongue papillae. In most cases they look swollen and enlarged. At times they can turn red and may result to a reddish sore tongue if they are severely affected by heat.

Another condition responsible for inflamed tongue papillae is acid reflux. People who have this problem experience heartburns, hiccups, regurgitation, blood spots on stool, etc.

Other tongue red spot causes

Here is an outline other possible causes of red spots on the tongue including the back of tongue and throat.

  1. Strep throat,
  2. Strawberry tongue,
  3. Lie bumps or transient lingual papillitis that is thought to be contributed by stress, trauma, splitting taste buds, etc.
  4. Conditions such as oral cancer, eczema and asthma,
  5. Exposure to certain medications,
  6. Excessive consumption of alcoholic spirits or drinks,
  7. Acid reflux,

While many children are victims affected by oral thrush, there are other conditions and diseases which can cause red spots on toddler’s tongue. White patches are at times noticed in young children and those underage. What leads to the appearance of red spots and patches in toddlers?

From what we have discussed, foot, hand and mouth disease is a culprit cause of red rash or spots on tongue common in young children.

One of the diseases responsible for formation of red spots amongst the underage children is scarlet fever. Children who have the symptoms as outlined above or at least had a strep throat should be taken to clinic for testing. Otherwise, scarlet fever can be a serious infection which may result in other complications.

Another cause of small red marks on tongue surface in young children is canker sores that result after tongue bites or injury. In toddlers and young children, cancer sores are symptomatic of “small, open and painful sores that are white or yellowish with a red border on the inner lips or cheek, gums or tongue.” [familydoctor.org]

NOTE: A typical nature of canker sores is that they affect the inside of the mouth – unlike cold sores which are fluid-filled blisters that occur as red spots on tongue and lips and around mouth.

Other things responsible include inflamed papillae. If your baby has a tendency of getting strep throat and recurring small ‘blood’ bumps in mouth, under tongue or at the back of throat call your doctor quickly.

Yellow tongue with red spots

Is it possible to have a yellow tongue coating with red spots?

There could also be other reasons to account for apart from what we have looked at so far (whether the spots appear as red flat dots or raised).

What do red spots under tongue mean?

Moreover, if you have red or dark red bumps under tongue or on the floor of mouth that have lasted longer or keep appearing see your dentist urgently. It could be a serious condition or mean something bigger than non-malignant tissues.

Red spots on tongue STDs – is it HIV or Herpes?

Do STDs have any symptoms in mouth or on mouth? In advanced stages of infection HIV can cause dry mouth, tooth decay, enlarged saliva glands, cold sores and shingles among many other problems. Even though people living with HIV may have recurring sores in mouth or on lips does not idealy mean that it is caused by HIV virus. Rather, it is due to the fact that HIV greatly compromises the body’s immunity and robs it of its ability to fight infections. Why? When your immunity is weakened or compromised other infections can easily cause the spots.

A relevant example could be fever blisters caused by herpes. You will realize that an HIV patient is more likely to be infected with theses blisters symptomatic of red or raised bumps.
