Why havent two molars been replaced during tooth changing?

Normal Phenomenon:If during the tooth replacement period, the newly grown teeth do not show any obvious discomfort symptoms and do not affect normal chewing function, it is considered a normal physiological response. You can improve this by adjusting your diet, eating more harder foods, and using dental floss to clean your teeth to avoid bacterial infections.

Abnormal Phenomenon:

1. Delayed eruption of permanent teeth: Prolonged malnutrition may lead to a deficiency of calcium or zinc in the body, preventing the smooth eruption of permanent teeth and even causing pain. You can follow the doctor's advice and use calcium gluconate oral solution, calcium carbonate granules, and other medications. At the same time, you can eat foods rich in quality protein, such as eggs and lean meat, to assist in relieving the condition.

2. Retention of deciduous teeth: If the deciduous teeth are injured or congenitally missing, it may affect the growth of new teeth, causing the above symptoms to a certain extent. In this case, patients should promptly go to the hospital's dentistry department for treatment by extracting the deciduous teeth to prevent the condition from worsening.

Additionally, it could also be caused by dental caries or other reasons. It is recommended to promptly visit a regular hospital for examination and treatment to avoid delaying the condition.
