Mouth-Sinus Communications - How to Lessen the Risks
If you have had an upper premolar or molar tooth removed, there is a small risk that a
communication between the mouth and sinus may develop.

You may not be aware of this for several weeks (it can develop as late as 4 – 6 weeks after the
extraction).  It will often manifest itself as a discharge of fluid from the nose after drinking,
possible discharge of pus from the nose, acute and chronic
sinusitis and a foul taste in the
mouth and smell in the nose.

To minimise the risk of developing this communication between the mouth and sinus,


YOU SHOULD NOT:

  • Smoke (this slows the healing of the extraction socket and makes you more likely to
    develop an infection in the socket which increases the risk of developing the mouth-sinus
    communication) for at least 72 hours.

  • Blow your nose or forcefully sneeze (this increases the pressure within the sinus and
    increases the risk of developing the mouth-sinus communication).

  • Use straws or whistle for the next 72 hours

  • Go flying for the next 4 – 6 weeks (the cabin is pressurised and this increases the risk of
    developing the mouth-sinus communication).


YOU SHOULD:

  • Use nasal decongestants (such as Ephedrine nasal drops, Oxymetazoline &
    Xylometazoline) as this reduces the degree of swelling of the nasal lining and lessens the
    likelihood of sneezing.

  • Use steam inhalations augmented with  Karvol or Olbas oil.

  • Use an antiseptic mouth-wash (such as Corsodyl) as this lessens the likelihood of infection
    and speeds healing.

  • Sneeze with your mouth open as this lowers the pressure within the sinus and lessens the
    likelihood of raised pressure creating the mouth-sinus communication.

  • Take the antibiotics and finish the course (if prescribed).
