If a new tooth grows without loosening, you can choose to observe it temporarily or extract it directly, which should be chosen according to your personal situation.
1. Temporary observation: If the tooth has not fallen out, new teeth grow, and there are no other symptoms, and will not affect the normal development and growth of permanent teeth, you can first observe, without special treatment for the time being. During this period, you should pay attention to oral hygiene and insist on brushing to prevent tooth decay.
2. Direct extraction: For the growth of permanent teeth is limited or the teeth are crooked, crowded and other cases, it is generally recommended to extract the milk teeth, which can promote the normal development and growth of permanent teeth and prevent the position of the surrounding teeth as well as the permanent teeth from being skewed.
If the permanent teeth grow out without loosening of the milk teeth, you should seek medical advice in time, under the guidance of a professional physician, and never take the liberty to deal with them without authorization.
