Pictures of tongue needed.

Detailed Answer:
Hi, I have gone through your question and understand your concerns.

It is difficult to narrow the exact cause/ diagnosis of white tongue and mucosal mouth soreness, because there are many underlying conditions that may feature such symptoms.

Here are some probable causes:
1.papillae hypertrophy or inflamation from dry mouth, dehydration, mouth breathing, mechanical irritation from sharp teeth, smoking.

2. conditions that may be associated with white tongue include prolonged use of antibiotics can predispose yeast infection, leukoplakia, geographic tongue, and serious systemic infective diseases associated with immune system compromise, usually associated with fever and other organs symptoms.

Headache can be related to fever if any, or may be a independent symptom.

Brief Answer:
Most probably candidal infection.

Detailed Answer:
Hi again and thanks for uploading the photo.

Seems to me like candidal glossitis, a fungal infection, is the most probably diagnosis. This is confirmed if you scratch the tongue the covering layer will be scrapped.

It responds to anti fungal treatment (Nystatin eg.).

If no scraping, then tongue papillae inflamation by smoking, alcohol, dehydration is the cause.This condition doesn't need treatment, avoiding predisposing factors and good oral hygiene should improve symptoms.

Oral candidiasis can be related to insuficiency of immune system in some cases, so this possibility should be discussed with your primary care Doctor.

Hope I helped you.
Wishing you good health.
