Children with double rows of teeth can be treated by removing milk teeth, orthodontics, exercising chewing ability and other methods. 1. Extraction of milk teeth: At this time, the milk teeth are not lost in time, but the permanent teeth have already erupted. Go to the dental clinic in time for examination and extraction of the corresponding milk teeth to minimize the impact on the eruption of permanent teeth. 2. Orthodontics: Nowadays, most children have double rows of teeth. If the milk teeth fall out too late, the growth position of permanent teeth will be relatively skewed, and it may be difficult to return to the normal position. In this case, you need to wear braces or orthodontics to improve the situation. 3. Exercise the ability to chew: let the child eat more peanuts, apples, corn and other chewy food, will have a good stimulating effect on the milk teeth, prompting the milk teeth to fall out on time and improve the phenomenon of double rows of teeth. In the child’s tooth replacement period should pay attention to observe the growth of the child’s teeth, found abnormalities should be timely to take the child to the hospital for orthodontic treatment.
