Press and stroke the striped areas in the figure. Results should come within 5 to 10 minutes. Repeat as many times per day until the pain subsides. You can also use small pieces (5mm edge) of a medicated plaster (Salonpas) and apply them to the striped spots indicated in the figure. In case of tooth decay, a dentist must be consulted for further and more extensive treatment.
