shut off the power to the box, switch out the breaker and resture the power
Check the circuit panel / breaker box. The tripped breaker should be partway between 'OFF' and 'ON'. If nothing else, turn the breakers off then on, one at a time and when the tripped breaker is reset, the circuit should be live again. Also check GFI outlets. If one is in fault condition, it will need to be reset. If the tripped GFI outlet is protecting other outlets, they will come back when the tripped GFI is reset. These sockets seem to hide in many cases... Behind microwave ovens for example or refrigerators.
It takes a finite amount of time to trip a breaker. The short you caused may not have tripped the breaker. If the dryer is no longer working there may be an internal reset that has tripped.
If the breaker is damaged it will not reset to the on position. It will stay in the tripped position.
To reset a breaker move the handle completely to the off position. If it had tripped you will feel a little resistance as it goes to the off position. If this doesn't restore the power the breaker is either bad and in need of replacement, or there is a persistent fault in the circuit causing the breaker to immediately re-trip. Breakers are safety devices.
Most of the controls on gas water heaters have a one time use overheat sensor that when tripped cannot be reset, the control has to be replaced.
