Loss of taste but still able to smell

The tongue detects basic tastes, while smell adds much of the detail people experience as flavour. A person can therefore recognise coffee or soap by smell but find food flat or different. Dry mouth, oral infection, tongue irritation, dental problems, recent illness, smoking, and some medicines can affect taste. Nasal congestion may still play a part if airflow is only partly reduced.

Check whether the change affects every food or only certain flavours. Note mouth soreness, coating, ulcers, thirst, new dental products, and any medicine started before the symptom. These clues help separate a local mouth issue from a wider sensory change.

Drink enough fluid, maintain gentle oral hygiene, and avoid tobacco and irritating mouth products. Choose nourishing foods with appealing textures and temperatures while the symptom lasts. Do not scrape the tongue aggressively or stop prescribed treatment without advice. A pharmacist can review possible medicine effects, while a dentist or doctor can examine the mouth if there is pain, dryness, or an ulcer.

If the change began with cough, fever, or congestion, consider COVID-19 testing according to local guidance. Track improvement rather than repeatedly challenging your senses with strong smells.

Get urgent help for facial weakness, sudden speech or vision changes, severe headache, breathing trouble, or inability to swallow. Arrange prompt assessment for a persistent mouth ulcer, unexplained bleeding, marked swelling, severe pain, or dehydration. Book routine care when taste remains altered, affects nutrition, or follows a new medicine without improving. A clinician can examine your mouth, nose, nerves, and medication list.

Ask whether your mouth, teeth, medicines, or recent infection could explain the pattern; whether dryness needs treatment; and when persistent symptoms should be reviewed by a dentist or ear, nose, and throat specialist.
