Sinus Precautions


During tooth removal, the sinus may be opened, entered, or bruised. Damage to the sinus can occur when the root of the tooth is very near or extends into the sinus or when there is no bone between the tooth root and the sinus. These situations can cause a root or tooth to fall into the sinus during surgery or cause an opening between the tooth socket and the sinus. When any of these conditions occur, special care must be taken to ensure the proper healing of your sinus.

Things to Avoid

  • Blowing your nose
  • Sucking on a straw
  • Smoking
  • Rinsing your mouth vigorously

These activities can cause the exchange of air or fluids between the sinus and the mouth that can result in a persistent opening between your sinus and mouth.

Special consideration for sneezing

If you are going to sneeze, hold your mouth open during the sneeze.

Nosebleeds/Sinus Drainage

You may experience a nosebleed or some drainage from your sinus after surgery. This is a common symptom and it will gradually decrease and stop.  Depending on the size of the opening in your sinus, you may be given antibiotics and decongestants. Use these as instructed.

If you notice air or liquid going from the mouth into the sinus, contact your surgeon to see if any additional instructions are needed.

Follow-up Appointment

It is important that you have a follow-up appointment for an examination of this area. Generally, the sinus opening will heal without problems within 2-to-4 weeks after tooth removal. If the opening is not healing properly, the surgeon will recommend further treatment options at the follow-up appointment.
