Hello, You had an unfortunate accident and complicated surgery. Are you still experiencing some signs of inflammation? There definitely may have been nerve damage. This should be discussed with your surgeon. You should expect a long healing time frame. You may experience areas with paresthesia. The nerve sensation may return to these areas gradually over time. A damaged or cut nerve indicates a permanent loss of sensation. Other nervesmay gradually add some sensation to an area. Trauma to teeth can result in nerve damage that requires root canal therapy and restorations. Your oral surgeon will refer you back to your general dentist for further evaluation. Depending on the extent of your accident you may need the services of an orthodontist and a periodontist. Thank you for your inquiry. I hope you continue to heal and feel additional return of areas lacking sensation. Certain anti-inflammatory medications may assist healing. Prescription steroids can be used for more severe areas of inflammation. Your surgeon with x-rays, clinical exams and details of your treatment will give you a realistic prognosis and options to improve your condition.
