Tooth replantation after a car accident?


Hello, doctor.
A few days ago, I had a car accident and my left upper front tooth was completely avulsed.
After being taken to the hospital, the dentist replanted it.
I would like to ask if it is normal for the replanted tooth to be positioned slightly lower than the adjacent teeth? Is it possible for the fixed tooth position to shift? Additionally, the gum around the replanted tooth and the adjacent front tooth (which also sustained impact but has an intact root) is experiencing sharp pain, especially around the replanted tooth's gum.
Could this be due to inflammation? Lastly, how should I maintain oral hygiene to minimize the risk of infection? Currently, I only rinse my mouth after meals and use a milder mouthwash (I am hesitant to brush my teeth).
Thank you for your help!

The recently replanted tooth is positioned slightly lower due to the formation of a blood clot in the socket that was injured, and the periodontal ligament tissue is also inflamed and swollen.
The fixed teeth do not move significantly as long as they do not endure excessive occlusal forces.
However, the replanted tooth and the adjacent tooth may experience pain upon biting because the periodontal ligament and gingival tissue of the replanted tooth, as well as those of the neighboring tooth, are injured and inflamed.
During this period, it is advisable to use a soft-bristled toothbrush for brushing and interdental brushes for cleaning between the teeth, along with mouthwash to help disinfect the oral cavity.

After a traumatic incident like a car accident, dental injuries can be particularly concerning, especially when it involves tooth avulsion and subsequent replantation. In your case, where the front tooth was completely knocked out and then replanted, it’s essential to understand the healing process and care tips to ensure the best possible outcome.


Initial Concerns Post-Replantation
1. Tooth Positioning: It is not uncommon for a replanted tooth to appear slightly misaligned or positioned lower than its neighboring teeth immediately after the procedure. This can be due to swelling, the initial healing process, or the way the tooth was replanted. Over time, as the surrounding tissues heal and inflammation subsides, the tooth may settle into a more natural position. However, if the misalignment persists, it is crucial to follow up with your dentist or orthodontist for further evaluation.

2. Movement of the Replanted Tooth: Once a tooth is replanted and stabilized, it should ideally remain in place. However, there is a possibility of slight movement during the initial healing phase, especially if the periodontal ligament (the tissue that helps anchor the tooth in the jaw) has been compromised. If you notice significant movement or if the tooth feels loose, it is essential to consult your dentist promptly.

3. Pain and Sensitivity: Experiencing pain or sensitivity in the replanted tooth and the adjacent teeth is common, especially if there was trauma to the area. This discomfort can be due to inflammation of the gums or the healing process of the periodontal tissues. If the pain is severe or persists beyond a few days, it could indicate an infection or other complications, and you should seek dental care immediately.


Oral Hygiene and Care Tips
Maintaining proper oral hygiene after a tooth replantation is crucial to prevent infection and promote healing. Here are some tips:
1. Gentle Cleaning: While it’s understandable to be cautious about brushing the replanted tooth, it’s essential to keep the area clean. Use a soft-bristled toothbrush and gently brush the teeth, avoiding the replanted tooth initially. You can gradually introduce gentle brushing around the area as healing progresses.

2. Rinsing: Continue to rinse your mouth with a mild, alcohol-free mouthwash after meals. This can help reduce bacteria in the mouth without irritating the gums. You can also use warm salt water rinses to promote healing and reduce inflammation.

3. Dietary Considerations: Stick to a soft diet to avoid putting pressure on the replanted tooth. Avoid hard, crunchy, or sticky foods that could dislodge the tooth or cause discomfort.

4. Follow-Up Appointments: Regular follow-ups with your dentist are essential to monitor the healing process. They can assess the position of the tooth, check for any signs of infection, and provide additional care if necessary.

5. Pain Management: If you experience discomfort, over-the-counter pain relievers can help manage pain. However, consult your dentist before taking any medication to ensure it’s appropriate for your situation.


Conclusion
In summary, while some discomfort and slight misalignment of the replanted tooth can be expected initially, it’s essential to monitor your symptoms closely. Maintain good oral hygiene, follow your dentist’s instructions, and attend all follow-up appointments to ensure the best outcome. If you have any concerns about pain, positioning, or signs of infection, do not hesitate to reach out to your dental care provider for guidance. Your proactive approach to care will significantly contribute to the successful healing of your dental injury.
