Common Oral Surgery Procedures at ISCD

Wisdom Tooth Removal

Wisdom tooth extraction is one of the most common procedures performed by our oral surgeon. Impacted or partially erupted wisdom teeth can cause pain, infection and damage to adjacent teeth. Dr O’Neill uses advanced imaging and surgical techniques to ensure safe and predictable removal, with sedation options available for patient comfort. Learn more about wisdom tooth removal in Dublin.

Dental Implants

Dental implants are the gold standard for replacing missing teeth. As a specialist oral surgeon, Dr O’Neill places implants with precision, often in combination with bone grafting procedures where needed. Each case is carefully planned using CBCT imaging to achieve optimal positioning and long-term success.

Surgical Extractions

Complex tooth extractions that cannot be managed in a general dental setting are referred to our oral surgery team. This includes teeth with curved or fused roots, teeth in close proximity to the inferior dental nerve, and teeth requiring a surgical approach. Dr O’Neill has extensive hospital training in managing these cases safely. Read our specialist breakdown of tooth extraction costs in Dublin and when an oral surgeon is needed.

Bone Grafting

Bone grafting procedures help to rebuild the jawbone after tooth loss or trauma. This may be required prior to dental implant placement, or to preserve bone volume following an extraction. Our oral surgeon uses evidence-based grafting techniques to achieve predictable outcomes.

Sedation Options

We understand that oral surgery can be a source of anxiety for many patients. Dr O’Neill has a postgraduate diploma in conscious sedation and offers intravenous sedation for procedures at our IFSC clinic. This allows patients to undergo treatment in a relaxed and comfortable state. General anaesthesia is also available for more complex cases at affiliated hospitals in Dublin.
