Re: Sore cracked tongue
It could be caused by many things.
A sore tongue:
Without realizing it, if your top and bottom teeth are out of alignment, this can cause trama to the tongue.
Some people who grind their teeth unconsciously can develop a sore tongue.
Disorders such as diabetes, anaemia, some types of vitamin deficiency can be the problem.
Burning tongue is actually called "glossodynia" and some of the causes are:
Local infections, such as oral thrush (candidiasis)
Damage to the lingual nerve
Damage to nerves of the mouth during dental extractions
Certain meds such as diuretics and some blood pressure drugs.
Then there's a condition called "benign migratory glossitis" or "geographic tongue".
You get irregular and inflamed patches on the tongue surface. Often the borders can be white-ish. The tongue can be swollen, red and sore.
Mineral or vitamin deficiencies
Local irritants, such as strong mouthwashes, cigarettes or alcohol
Certain forms of anaemia
So, as you can see there are many things that a sore or burning tongue can indicate, mostly benign and treatable. If your discomfort continues, see your doctor.
