6) Numbness or tenderness in the mouth
Loss of sensation in your mouth can be one of the symptoms of mouth cancer. You may feel numbness anywhere in the mouth, but gums, lips, and tongue are the most common sites. In medical terms, this feeling of numbness is referred to as paresthesia. It generally occurs when the tumor damages the nerves or blood vessels in the mouth. Loss of sensation can be throughout the mouth or in patches. You must consult your doctor as soon as possible to diagnose the proper cause of the loss of sensation in different parts of the mouth.
