Advice after your nerve block for surgery
On this page…
Post-operative advice
- If there are small lacerations or cuts in the mouth, it is important to avoid agitating the affected site.
- Avoid spicy and hot food which might cause more discomfort or start bleeding.
- Bleeding may be controlled by applying pressure with some gauze or a clean handkerchief over the area for at least 5 to 10 minutes.
- If a tooth has been lost, the area will heal naturally. However, it is important to avoid disturbing the blood clot which is forming at the site.
- If there is excessive bleeding from the site this can be controlled using the measures outlined above.
- For bleeding occurring at the site of a lost tooth, pressure may need to be continued for much longer than for bleeding from a cut. Continue to apply pressure for at least 20 minutes.
- If the bleeding persists, contact a dentist as a matter of urgency.
- If your tooth has been moved, dislodged, or reimplanted you will need to see a dentist as soon as possible. In the meantime, keen the area clean by the use of a soft brush and chlorhexidine mouthwash, used 2 – 3 times per day, and warm salty water rinses 4 – 5 times per day.
