Thanks for asking the query,
You should mention the age of your child?
If it is a milk tooth so its will gradually be replaced by its permanent successor tooth, for this you need to take an x-ray of the affected region.
If it is a premanent tooth, so replantation or splinting can be done.
I would encourage you to take your child to the Dentist
, get an x-ray done for the correct diagnosis and treatment plan.
Hope this helps out,
