The upper back tooth definitely looks decayed .
An OPG( full mouth xray) would be recommended to check the spread and then either pulpectomy( Root canal in primary tooth of children) or removal followed by replacement is recommended.
Do not try any homely treatments, it would add on to the swelling and pain eventually
Next Steps
Consult a dentist immediately
