My 9 year old broke her top front permanent tooth, central incisor. We found the tooth and the dentist managed to adhere the original back on. About 75% of the tooth fell off. It has fallen out twice now in 10 months. She's very careful how she eats, never using her front teeth. There's just not a lot to work with to maintain the strength. She's too young for crowns or veneers. Are there any alternatives at this age? Thank you!
