"Teeter on the brink/edge of something" means to be very close to a dangerous or important situation that could have a bad outcome. For example, if a country is heavily in debt, it may teeter on the brink/edge of financial collapse. It can also be used for personal situations, such as someone teetering on the brink/edge of a mental breakdown. It's important to be careful and try to avoid falling into the bad situation.
