Tooth extraction is generally safe, but like any surgical procedure, there is a risk of infection during the healing phase. As a dentist practicing in South Korea, I often remind patients that early detection of infection is critical for preventing serious complications.

Understanding what is normal—and what is not—can help you act quickly and protect your oral health.

Understanding Dry Socket (Alveolar Osteitis)

Alveolar osteitis, commonly known as dry socket, remains one of the most painful postoperative complications following tooth extraction.
It occurs when the blood clot that normally protects the exposed bone dissolves or dislodges prematurely, leaving the socket exposed to air, food debris, and bacteria.

Incidence rates range from 2–5% in routine extractions and can reach up to 30% after impacted third molar removal.

As a dentist who has spent many years studying and performing root canal therapy, one lesson remains constant: the best tooth is your natural tooth.

In modern dentistry, patients often ask whether a painful or infected tooth should be removed immediately. While extraction may seem like a quick solution, preserving the natural tooth is usually the healthier long-term option whenever possible. Root canal treatment allows dentists to save teeth that would otherwise be lost due to infection, deep decay, trauma, or nerve damage.
