What is the direct answer?
What does this question mean?
The tongue, cheeks, palate, and gums can react to flavoring agents, foaming ingredients, whitening abrasives, or vigorous brushing. Burning may also occur with reduced saliva, oral candidiasis, nutritional problems, hormonal changes, or an altered nerve sensation. Use a soft brush and mild, unflavored toothpaste, avoid scrubbing, and note whether the sensation follows a particular product or affects several areas. Keep hydrated and arrange an examination if the symptom persists rather than repeatedly changing products without assessment.

Flavoring agents, detergents, and abrasive or whitening ingredients can irritate already sensitive mucosa; changing to a mild product may help identify the trigger.
When should you seek dental care?
See a dentist for burning that persists, visible white or red patches, ulcers, dry mouth, numbness, altered taste, or difficulty eating. Urgent care is needed for sudden swelling or trouble breathing or swallowing. Can thrush cause burning? Oral candidiasis can cause soreness or burning with removable white plaques or red tender areas, and it needs confirmation before antifungal treatment.
