I am 22 years old. Love to eat sugar when changing teeth, which leads to tooth loss. When I change my teeth, new teeth will grow out. Has the broken tooth been pulled out?

Yes, you should have a stranded deciduous tooth. You need to pull it out as soon as possible, so as not to affect the eruption of permanent teeth. Generally speaking, if deciduous teeth are not pulled out, they will occupy the position of permanent teeth, and permanent teeth will naturally grow crooked. Only by removing resistance can permanent teeth grow straight.

For teeth with "serious" caries, especially molars, X-rays are needed before deciding whether to keep or treat this tooth. It is recommended to see a doctor as soon as possible and treat it as soon as possible.
