A 3-year-old male's primary tooth F (maxillary left central incisor) is intruded due to trauma. What is the BEST treatment?

For intruded primary incisors in young children, watchful waiting (spontaneous re-eruption) is the recommended treatment UNLESS the tooth is intruded into the path of the permanent tooth bud. Antibiotics/X-ray monitoring supports this. Extraction may be needed if eruption doesn't occur or the permanent tooth is at risk. Splinting primary teeth is not indicated.
