Biting or burning your tongue with hot food or drink can cause pain and swelling. This should only last a few days.
A white tongue can be a sign of a health condition, such as anaemia, scarlet fever, lichen planus, leukoplakia, geographic tongue, mouth ulcers or oral thrush.
But do not self-diagnose. See a GP if you're worried.
Lichen planus can cause white patches on the tongue and inside the cheek.

Blotchy, red patches on the tongue that have a white or light-coloured border may be geographic tongue.
Mouth ulcers are round, painful and swollen sores that look like blisters and can appear on the tongue, inside of the cheeks, or the lips.

An itchy, red mouth with white patches on the tongue could be oral thrush. It's more common in babies and older people with dentures.
