My child is having a loose tooth along with some gum pain, he is still a child but the loose is a permanent tooth, is it needed to see a dentist now?

Yes: If it is his permanent tooth and loose I would go soon to make sure not fractured or some other reason to give him the best chance of not losing it

Maybe a baby tooth : In my experience, most of the time the child or parent mistaket a baby tooth for a permanent tooth. You can take a photo send to your child's dentist, the dentist will be able to tell.

Go to the Dentist: Good day; Could there not be a more appropriate time to visit a dentist. Usually initial visits are reasonable and preventive in nature.

Dental pain/mobility: Can indicate dental abscess, fractured tooth, insufficient room for permanent tooth to erupt, gum infection, para functional habit, fractured tooth-housing bone, and a whole raft of other possibilities. Absolutely call your child's Dentist. The sooner your child can be made pain-free, the better. The Dentist, who knows your child best, will advise you as to what to do next.
