Dr. Payne, a dentist of the old school, is the only one in the small town. Bob Bright, a young dentist with modern methods, arrives to set up in business. Payne uses every device to discredit the young dentist. However, Jane, Dr. Payne's daughter, falls in love with Bob. Jed, the town swell, is also trying to win her hand. Bob decides to teach Payne a lesson. He hires a tramp to go to the old doctor's office and assume a raging toothache. The tramp is instructed to yell with all his might as the operation goes on. Dr. Payne pulls and the tramp yells, driving away a half dozen other patients awaiting a similar fate. Finally the old doctor gets a raging toothache himself and he can't stop it. Bob is at the house calling on his daughter. Bob offers to stop the pain if the old man will allow him to marry the girl. Payne refuses and the toothache increases. However, Payne finally consents to the proposition and Bob stops the pain.
