Oral Can.cer: Symptoms You Shouldn’t Ignore.
6. Extreme Tooth Sensitivity

Pain when consuming hot or cold beverages can be a sign of tooth enamel wear, cavities, or gum disease. It can also indicate a deeper problem with the dental nerves.
7. Changes in Tongue Color
A red, swollen tongue can be a symptom of scarlet fever or a vitamin deficiency. If it turns black or hairy, it may be related to overuse of antibiotics or poor oral hygiene.
Taking care of your oral health is not only important to prevent cavities and dental diseases, but also to detect more serious health problems early. If you notice any of these symptoms persistently, consult a specialist for a proper diagnosis.
