Baby fell and knocked teeth, whether or not bleeding to the hospital for examination and consultation, the main treatment are the following: 1, the treatment of wounds: first of all, see if there is a wound, bleeding many times is the gums or lips injury, larger, deeper wounds are prone to infection or poor healing, the wound will be cleaned and stitched, easy to heal. Very small wounds can not be treated, pay attention to maintain oral hygiene, can be healed by themselves; 2, the treatment of teeth: generally to take pictures, to see whether the root of the tooth is broken, to see the relationship between the milk teeth and permanent tooth embryo. According to the specific situation, we can decide to treat conservatively or extract the teeth, such as the displacement of the baby teeth, and extract the teeth when the permanent tooth embryo is injured. If the displaced tooth is loose after reset or the tooth that was sagging is pushed back and then sags again, it should also be extracted. Younger patients, who cannot cooperate with the treatment, also need to have their teeth extracted and reviewed regularly, once every 2-3 days at first, then once a week, and gradually extended to once every 3-6 months after 2-3 months. Review is more important, after the tooth injury may appear other lesions need to be observed at any time; 3, prevention: baby just learned to walk, be sure to hold or hold, do a good job of protection measures to avoid bump or touch. Do a good job of prevention is more important than dealing with the injury.
