Cracked Tongue: Causes, Symptoms, Relief and More


A normal healthy tongue should have a fairly flat surface under normal circumstances. Also, it should have light, thin white moist coating but must have no cracks, (ulcerous) sores, cuts or teeth marks.

However, notes that fissured tongue (medically known as lingua plicata, plicated or scrotal tongue), is one with multiple furrows or grooves on the dorsal top surface. These fissures could be deep or shallow. The shallow furrows could occur in the middle or on the sides of your tongue.


What does it mean to have fissures or cracks in your tongue and what makes to crack? 

1. Injury including  Bites, Cuts, and Lacerations

The first way through which cracks will occur is through injuries. Below is a brief description of how your tongue may end getting cracks as a result of the injury.

a). Bites

The most common form of injury to the tongue biting which is accidental in nature. Usually, cracks that form from this kind of harm are shallow and tend to be found on the tip and the sides of the tongue because they are nearer to the teeth.

These cracks are slightly painful to touch. They may also be contributing to sores in the mouth when individuals take hot and spicy foods.

b). Cuts 

Secondly, besides bites, cuts is another possible way in which end up with cracks. Cases of cuts may appear anywhere i.e. under, on tip or sides of the tongue.

Common problems with cuts arise from habits such as eating dry and hard foods (e.g. betel nuts) with sharp edges, using pointed tools to work on teeth or presence of broken teeth in the mouth. The nature of cracks cuts depends on what has caused them. However, if cuts are severe, they must be very sore. Then this may lead to chronic cracks that take longer to heal.

c). Deep Cracks and Lacerations

Another serious form of injury that may cause cracks in the tongue is a laceration. Lacerations may range from deep cuts tearings.

Major causes include head concussions, falls, seizure and other mechanisms that use great force. For instance, when you have had a head concussion, chances are that your tongue may be caught in between the teeth as the lower jaws are closing due to force from the knock of an incoming body.

Lacerations are considered emergency because some are accidents will lead to deep and huge cracks.

2. Very hot, Spicy foods or objects

Eating hot foods could be harming not only your tongue but also the lining of the mouth. The hot objects or food cause a lot of discomforts. Heat will physically cause your delicate mouth lining to peel and be cracked mildly.

After peeling has occurred, it becomes more vulnerable to infections, be it fungi or bacteria, which quickly multiply in the mouth and around lips.

3. Teeth Grinding

This problem is common in children. Those who normally grind while asleep are at risk. Cracks on the tongue from this malpractice are more likely to occur on the sides as well as on the tip. To avoid it for your loved ones acquire some teeth grinding mouth guard for them and you also.

4. Poor Nutrition and Vitamin Deficiency

Vitamins are very important and a crucial part of your body’s nutrition. For instance, the vitamin B family nutrients are used by the body to synthesize fat and boost metabolism. Let us briefly look at some of the vitamins which they are inadequate can cause tongue cracking.

i. Riboflavin Deficiency or Ariboflavinosis

As an important vitamin in nutrition, riboflavin helps in the uptake of other yet essential vitamins such as B-6, folate, Iron, and niacin. Signs that will show that it is too little in the body include swelling or soreness in throat, swollen tongue and cracked skin around the corners of the mouth. The swelling may trigger cracking if slightly irritated or inflamed.

In addition, it is important to take food and other supplies that have riboflavin but too much of it has negative sides. For example, high concentrations of riboflavin may increase risks of getting kidney stones, sensitivity to light, numbness, and prickling or burning of the skin. You are expected to inquire and get the right amounts for various age brackets.

Natural supplies which should be eaten therefore are as follows:

  1. Green vegetables (broccoli, spinach, etc.) especially dark-green ones,
  2. Protein-rich foods such as fish, poultry,
  3. Closed packed dairy products e.g. milk and yogurt.

ii. Folic acid

Also known as vitamin B-9, folic acid can be another reason why there may occur tongue cracks. As we had mentioned in the introduction, sores can aggravate the condition of already existing and speed up the formation of cracks.

This is a very important nutrition component for women during their pregnancy period. It is also meant for breastfeeding mothers and all adults in the productivity stage. There is a wide range of those looking for food sources with a rich source of folic acid. They are root vegetables such as tulips, beans, salmon milk not forgetting whole grains.

iii.  Biotin

As another group member of vitamin B-family, a deficiency in biotin is more likely to result in paleness, fatigue and anyone may fall victim and risk of cracking or fissures in tongue

5. Certain Disorders, conditions, and diseases

Here are more conditions, syndromes and other causative factors for these cracks and fissures.

a. Melkersson-Rosenthal syndrome, MROS, MRS

Although rare, Melkersson Rosenthal syndrome or MROS is a neurological disorder. Individuals who are affected are “characterized by recurrent, long-lasting swelling of the face, granulomatous cheilitis, facial muscle weakness (palsy) and a fissured tongue.” [].

Apparently, MRS or MROS is linked to genetic factors which particular family members have and are affected. Well, if some family members are allergic to certain food diets, the symptoms are thought to be presently visible.

How is MRS diagnosed and treated?

A patient’s history is indispensable in constructing a susceptible occurrence of this syndrome. Basically, diagnosis requires a biopsy but in some instances, a laboratory study of patient’s history is final to confirm MROS.

In most cases, Melkersson-Rosenthal syndrome requires no treatment since the symptoms may go away on their own. Otherwise, should the symptoms persist treatment are available- antibiotics, corticosteroid injections or non-steroidal anti-inflammatory medicines. Other advanced therapies include surgery and radiation.

b. Down’s Syndrome or Trisomy 21

Down syndrome is a genetic disorder and a great challenge from childhood to adulthood. This syndrome is associated with fissures.

According to WebMD “fissured tongue occurs in as many as 80% of children with the chromosomal disorder.” Babies born with this condition begin to explicitly show up signs as they grow up. Characteristically, as noted earlier, fissured tongues are distinguished by their prominent grooves.

Unfortunately, Down’s syndrome has no cure. However, with proper therapy programs being put up in certain countries such as the US, have seen life expectancy incredibly increase to around 60 years.

c. Geographical Tongue

The effects of a geographical tongue are a bit tricky because the symptoms can be experienced during meal especially when hot foods, spicy or salt-containing foods are served. This benign or harmless condition at times replicates itself in fissures if at all grooves are likely to develop within the splits.
