Oral surgery
Oral surgery covers the procedures that go beyond a filling or a cleaning: removing teeth, preparing the jaw for implants, and treating problems in the gums and bone.

What it includes
Simple and surgical extractions, wisdom teeth, bone and gum grafting, and the placement of dental implants.
Comfort and clear answers
You will know what is planned, why, and what recovery looks like before anything is scheduled. The area is always fully numbed.
