These foreign bodies are generally symptomatic and show signs of inflammation pain and purulent discharge. An unusual case of asymptomatic traumatic foreign body (stone) impacted in the lower anterior region due to an accident 3 years back, which was diagnosed during routine oral examination is reported.
