Dental Advice faq from Seattle Area Dentist

It is quite common for upper molars to have roots which are adjacent to a sinus. For someone with healthy teeth who is not experiencing any adverse symptoms, this is not a concern. Dentists will often point out the proximity of the sinus to a tooth in situations when the tooth needs to be extracted or perhaps have a root canal. Referred pain, in which a person feels a toothache due to a sinus infection, is also possible in these teeth, and is a symptom which will disappear along with the sinus infection.
