Are you sure it is mouthrot? Leos can and do get stomachitis (mouth rot.) It can be like a yeast infection, similar to thrush in babies, and is usually an indicator of something else going on in the leos body. Take the gecko to the vet for treatment ASAP. It can be bacterial in nature, so usually a culture is necessary to determine how to treat it appropriately.
In the meantime, take a Q-tip and get it wet. Then, put a few drops of 2% hydrogen peroxide AND a few frops of iodine on the wet cotton. Swab out the gecko's mouth, paying special attention to the gums. Leave it in there for a few minutes and rinse the mouth out with the other end of the Q-tip. Do this a couple of times a day until you can get to the vet.
