Burning tongue and bad taste in mouth
A burning tongue with a persistent bad taste can come from dry mouth, irritation, reflux, infection, medication effects, or nutritional problems.
What can cause a burning tongue and persistent bad taste?
A burning tongue with a persistent bad taste can come from dry mouth, irritation, reflux, infection, medication effects, or nutritional problems.
How can saliva and tongue inflammation alter taste and comfort?
The tongue contains sensitive mucosa and taste receptors, so inflammation or altered saliva can cause burning and a metallic, bitter, or foul taste. Dental plaque, gum disease, oral thrush, a rough restoration, reflux, and some medicines are possible contributors.
What can you do to ease tongue burning and bad taste?
Drink water regularly, avoid tobacco, alcohol, very spicy foods, and irritating mouthwashes, and gently clean the tongue. Note when symptoms occur, recent medicines, dry-mouth symptoms, and any visible coating or sores.
Which burning tongue symptoms need prompt dental care?
Seek prompt care for swelling, fever, difficulty swallowing, a spreading rash, or trouble breathing. Book an assessment for symptoms that persist, recur, or occur with mouth sores, weight loss, or bleeding.
What causes should you discuss with your dentist?
Ask which oral and medical causes fit the examination, whether saliva flow is reduced, and whether medication or blood tests need review.

What will a dentist check?
