My daughter fell and broke her front two teeth. What should we do?

It really depends on how bad she broke her teeth and if the teeth are primary or adult teeth. If primary teeth, they fall out or she loses them by 6 or so. If adult teeth, you should have them fixed asap.

The degree by which it broke will affect outcome. Without seeing it, it could be anything from a simple chip which is more of an esthetic and minor function complication. Or a major break with nerve involvement, which will lead to the devitalization of the tooth. It will require more treatment. See your dentist for recommendation.

My daughter's filled cavity is causing her pain again. What should I do?

Some children/infants experience tooth eruption a couple months later than the average. Conversely, some may see teeth sooner. I would not be too concerned about it. However, if after a few more months you are still unsure or have yet to see any teeth erupt, it would be advisable to seek a dentist to use radiographs (x-rays) to assess the presence of teeth and
staging of eruption.

Hope that helps.

It all depends on how badly you chipped it, mobility, and if there is pain associated with the tooth. Best is to seek a dentist to examine the tooth and determine what needs to be done. In some cases, it might just be a simple touch up, and in drastic cases, it may require extraction. Without a professional examination and X-rays, it's very difficult to determine the outcome of trauma.

I had a root canal and the area still hurts. Is something wrong?

That all depends on the individual. Some kids lose their teeth as soon as they are erupting, some it may take a month or so. On average, kids lose their first set of teeth around 6-7, so I don't think it will be too long since the baby teeth fell out on their own I'm assuming. Usually, that is a sign the adult teeth are coming. For a better answer, visit your dentist to get an X-ray to see how far along the adult teeth are or to get an idea if there is anything preventing eruption. It would not be a bad idea to visit your dentist if the adult teeth don't show up after a month. Nothing to lose sleep over, though.
