There are around one-fourth of school children that suffer from the pain of their permanent teeth. In cases of severe injuries like tooth knocked in a child, it is always better to visit a dentist.
Many parents do not actually know what to do if the tooth of their child is knocked out. Even if some of them have an idea about it, they might not be confident to put the plan into action.
You should assure that your child has a well-fitting mouth guard and they wear it for all sorts of sports they play. Mouth guards are not meant to be kept in pockets. There available wide varieties of mouth guards and a child may select any one as per his/her needs. Mouth guards can help save tooth from knocking out while playing football, cycling, etc.
The sooner the tooth is back in the mouth the better it is. This is because the root of the tooth is covered in cells which are to be kept alive. This is essential because only this action can help tooth reintegrate back into the mouth. It is always better to replant the knocked out tooth within 15 minutes of trauma.
You should contact your dentist as early as possible to get the right treatment without getting late.
