Sinus Expansion Due to Missing Teeth - Advanced Periodontics & Implant Dentistry

One of the consequences of losing top teeth, is that the sinus cavity will expand, causing several further problems, if not treated early. Let’s take a look at the progression of sinus expansion after upper tooth loss:

All teeth are present, Sinus is protected

The presence of teeth keeps the maxillary sinus in place.

Missing teeth

Missing top teeth gives the sinus (which contains slight pressure) the opportunity to expand.

Over time, the Sinus expands

The maxillary sinus expands into the edentulous area, subsequently causing bone atrophy.

Continued pressure & forces cause stress

The expanding sinus destroys surrounding bone. Bottom teeth continue to erupt and traumatize soft tissue.
