Foreign Body Reactions

The presence of a foreign body in or near the oral tissues can cause injuries resembling the burns, ulcers or recessed areas of traumatic lesions. Introducing amalgam during an extraction or abrasive agents during a polishing procedure may cause a local reaction. The most common foreign body is a popcorn hull. Removal of the foreign body is usually sufficient to encourage healing.
