A dentist has warned of subtle mouth signs that could explain fatigue and cause heart problems.
When we experience extreme tiredness or chest niggles, we might not automatically think about our oral health. However, a professional has brought up cracked mouth corners and pale gums that could point to signs of a nutrition deficiency sapping your energy and leaving you flat.
Iron deficiency anaemia, a condition where the body lacks the necessary iron to produce healthy red blood cells, often shows subtle signs in the mouth, according to oral surgeon Dr Andrej Bozic of Dentum.
“The mouth can be a mirror of what’s happening in the body,” Dr Bozic explained. “When iron levels drop, reduced oxygen delivery affects oral tissues, leading to noticeable changes.”
Key oral symptoms include pale gums, a smooth or sore tongue (atrophic glossitis), and cracks at the corners of the mouth (angular cheilitis).

“Atrophic glossitis, where the tongue appears smooth and inflamed, is one of the more striking signs of iron deficiency,” Dr Bozic said. “It occurs because the body lacks the haemoglobin needed to repair and maintain tissues.”
Pale gums, another common indicator, result from a reduced red blood cell count. “Patients often don’t realise pale gums could signal a systemic issue like anaemia,” he said. “It’s something dentists spot during routine check-ups.”
Angular cheilitis, or painful cracks at the mouth’s corners, is also linked to anaemia. “Iron deficiency weakens the immune system, making infections more likely and causing these cracks to persist,” Dr Bozic said.

Early detection matters, as Dr Bozic stresses that addressing iron deficiency early is crucial: “Left untreated, anaemia can lead to serious health issues, including fatigue, heart problems and delayed healing of oral tissues.
“Your dentist may be the first to notice these subtle signs, so it’s vital to take them seriously.”
For anyone experiencing persistent oral symptoms, seeking medical advice is essential.
“Don’t dismiss signs like sore gums or unusual tongue appearance,” Dr Bozic said. “We recommend further tests to rule out anaemia or other underlying conditions if we see these signs.”
A balanced diet rich in iron is vital to preventing deficiencies. Eating foods like spinach, beans, red meat, or fortified cereals is advised. For vegetarians or vegans, find plant-based iron sources and consider supplements if needed.
Regular dental visits are equally important.
“Dentists don’t just care for your teeth,” said Dr Bozic. “Routine check-ups can uncover broader health concerns. Our mouth is often the first to show signs of deeper issues. Pay attention to it – it could save your health.”
