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).
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 withKarvol 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).
