On Dec. 18th (on a Thursday) I had 2 teeth capped (front bottom teeth).  The following day my bottom lip was so swollen it looked as though I had a dip of tobacco.  I called my dentist on Mon. to say something was very wrong.  My mouth now looked as though I had a stroke.  My dentist put me on penicillin & said it appeared to be an ulcer that may have become infected.  There is a deep hole at the lower base of my gum line.  My chin is sore all the way to the bottom.  The lesion does not appear to be as angry looking however my lip is still distorted & the pain is almost unbearable at times especially after I have tried to eat.  My dentist has done some research but he is still puzzled at what happened.  My fear is that my lip is never going to look normal again.  My family members notice the change.  Can you give me any insight??  Thanking you in advance.

Hello, There can be trauma to surrounding tissue that will just need time to heal. Follow instructions provided by your dentist. You indicate improvement. As long as this continues, do not worry. Gentle care and cleansing with warm salt water should be helpful. Anti-inflammatory medication such as Tylenol or Advil may assist healing by reducing your symptoms. Your dentist can prescribe a rinse known as magic mouth which may help reduce your symptoms if you need additional immediate relief with a combination of analgesic and anti-inflammatory medications. Consult with an oral surgeon for a second opinion if you continue to have concerns. Monitor with follow-up visits with your dentist. Look for changes that include swelling, redness and heat that would indicate an increasing infection. There are changes that can occur such as an infection or tooth abscess, periodontal conditions or allergic reactions. Please do not panic with only two days gone by. Expect two weeks for a large ulcerated area to heal. Avoid irritants.  This can be a sensitive area for injections in the mouth. Perhaps you had local anesthetic here that can contribute to some post visit discomfort as well. Thank you for your inquiry. I hope you continue to feel better and that my suggestions offer more relief.
