Can a Tooth Really Cause a Sinus Infection?

Can a tooth that "isn’t getting worse" still be dangerous?
In this episode of Practical Treatment Planning, Dr. Lee Sheldon walks you through the dangers of monitoring an infected tooth without acting — and how a CT scan changed the game.

Using real clinical imaging, you’ll learn:

• What X-rays and CT scans reveal about hidden infections
• How a thin layer of bone may be the only barrier between infection and the sinus
• Why proactive treatment is sometimes essential — even when symptoms seem stable

📌 Lesson:
Don’t assume a tooth is stable just because it “doesn’t seem to be getting worse.” The patient’s health — and yours — could depend on a deeper look.
