We call cysts the spaces formed as a result of inflammation at the bottom of the teeth. Cysts are treated with Root Canal Treatment. In the worst case scenario, they are extracted and cleaned and your bone repairs that cyst space. If long-term cysts cannot be treated, they expand. For this reason, a cyst should be treated as soon as it is detected. When treated, it immediately loses its ability to spread or become a focal infection focus. Do not worry.
