Would you agree with the following?
Sinus pressure or infection can indeed cause pain which feels as though it?s coming from teeth. Here are some signs that it?s a sinus problem and not a tooth problem: the pain is only in the upper back teeth, it?s a continuous dull ache and/or tenderness to chewing or biting vs. sensitivity to hot or cold, and you have sinus or nasal congestion on the same side as the tooth pain. In this case try a decongestant nasal spray. If in doubt, see a dentist to examine the painful teeth.
And;
Absolutely! The maxillary sinuses are hollow air filled cavities on either side of the nose. Some of the sensory nerves that supply the upper back and middle teeth run through the maxillary sinuses. When the sinus membranes are inflamed or infected, the nerves can be irritated resulting in toothache symptoms. An upper toothache can often be the major symptom in sinusitis.
Therefore I am saying I have maxillary sinusitis and sudafed should sort it?
