I my opinion , you can try gargles with warm water 2-3 times daily , is the pain and swelling still persist , it's better to go to the dentist and have an IOPA ( x ray ) , if the tooth is in condition to be saved them it's fine , otherwise extraction is the best option for this condition.
Next Steps
warm gargles first of all (2-3 times daily)
visit a dentist .
