Teeth sinus anatomy

Can missing teeth cause sinus problems?
Your Sinuses May Be Affected
Even a small change in the size of the jawbone, such as from a single missing tooth can cause problems with your sinuses.
Your sinuses are already close to your teeth.
In fact, some people's back molars' roots penetrate the sinus cavity..
How are sinuses connected to teeth?
The largest sinuses are a pair above the back teeth of your upper jaw.
The roots of the upper teeth are very near or may even extend into the sinus cavity.
Consequently, inflammation in the sinuses might cause pain in nearby teeth.
Similarly, damage to or infection in a tooth may lead to persistent (chronic) sinusitis..
Which teeth communicate with sinus?
The caudal maxillary sinus is usually positioned immediately dorsal to the apices of the upper 10s and 11s (fifth and sixth cheek teeth), and communicates with the dorsal conchal sinus via the large frontomaxillary aperture..
Which tooth is closest to sinus?
The present study also found the first premolar root tip to be farthest and the second molar buccodistal root tip to be closest to the sinus floor on both right and left sides..
It's possible for them to accidentally poke through the sinus lining and create a very small hole, or sinus communication.
Usually, this results in symptoms like: Feeling air go across the socket of your tooth when you breathe.
A runny nose or post-nasal drip.
The maxillary sinus, or antrum of Highmore, lies within the body of the maxillary bone and is the largest and first to develop of the paranasal sinuses.
The alveolar process of the maxilla supports the dentition and forms the inferior boundary of the sinus.
There are four paired sinuses in humans, all lined with pseudostratified columnar epithelium: the maxillary sinuses, the largest ones located under the eyes in the maxillary bones;[2] the frontal sinuses, superior to the eyes within the frontal bone; the ethmoid sinuses, formed from several air cells within the ethmoid _{Feb 11, 2023}

The floor of the sinus is formed by the alveolar and palatine processes of the maxilla and lies below the nasal cavity [3,5], which is usually located from the mesial part of the first premolar to the distal part of the third molar with the lowest at the first and second molar (Fig.

The maxillary posterior teeth root tips are in close relation to the floor of the sinus, with the root tips of the molar being closer to the floor of the sinus than the premolars [7]. CT studies have revealed the mean distance between the maxillary posterior teeth and the sinus floor to be 1.97 mm [7].

Surgery to enlarge the paranasal sinus drainage pathways

Functional endoscopic sinus surgery (FESS) is a procedure that is used to treat sinusitis and other conditions that affect the sinuses.
Sinusitis is an inflammation of the sinuses that can cause symptoms such as congestion, headaches, and difficulty breathing through the nose.
