A burning mouth or tongue could be a warning sign of diabetes, said the Cleveland Clinic.
It could be caused by thrush – a fungal infection of the mouth and tongue, it added.
High blood sugar levels in the mouth and saliva provide the perfect environment for fungus to grow.
“People with diabetes face a higher-than-normal risk of oral health problems,” said the health site.
“If blood sugar is poorly controlled, it is more likely that oral health problems will arise.”
