Hello, I have read you inquiry. Biting your tongue could cause a reaction that you describe. Warm salt water rinses, avoiding spicy and acidic foods, anti-inflammatory medication such as Tylenol or Motrin and continued daily home dental care will assist healing. Keep well hydrated and proper nutrition with balanced vitamins especially vitamin B. Avoid irritants such as smoking and alcohol. you can apply a benzocaine numbing gel if sensitive. You can can have a remaining solid feeling for a longer period with no concern if you bit the tongue rather hard. It takes time for inflammation to resolve. Observe the area. Look for ulceration and monitor appearance. If your condition worsens or causes an increase in pain, swelling or function, see your dentist for an evaluation. Monitor tongue for any other changes such as size, color, and coating. Other considerations: -inflamed papillae -growth, cyst, tumor -allergic reaction - rough , broken teeth or dental appliance -grinding teeth, likely at night -change in or stressful bite -infection: bacterial, fungal, virus Thank you for consulting Heathcare Magic. I am glad to assist you further if you can provide additional details or have more questions.
