Hi! welcome to Healthcaremagic. I read your query. A tooth is attached to gums by periodontal ligaments. During natural shedding process there is gradual breakdown of these attachments leading to tooth fall. Since you did it by force a few remaing ligaments may be left sticking and are hanging out. Gradually it would be shed off or get molded. But if its causing any problem in eating or is inflamed, then you can visit a dentist and get it removed. Its a small procedure done with local anesthesia. Post that she may need antibiotic and paunkiller for 2-3 days. Hope the answer helps you. Thank you!
