The first molar, also known as the sixth age, is the earliest permanent tooth to erupt in life. Because they are still young, they have poor oral care and brushing habits. If you do not do regular oral examination, decay is inevitable, and when you find that your teeth are uncomfortable, they are basically rotten. What should we do in the face of this situation? The dentist will tell you to take a panoramic film of your mouth. If there is a third molar present, then it is lucky. Maybe there is a better solution. Solution: Here is a case of a first molar stump. We removed four first molars (one of which had a root remnant) and moved the second molar forward to replace the first molar. After about 2 years of orthodontic treatment, the second molar was completed anteriorly and no trace of missing teeth was visible at all. All teeth occluded well.
