The base chakra is ruled by Saturn which rules the bones and teeth. I am not sure if the teeth can be fixed with work on the base chakra though. See a dentist ASAP, tooth (bone) pain is some of the worst there is. The problem has already manifested, by the time you get a working ready and wait for the stars to align, how bad will it get?
With an emergency level of urgency regarding teeth, always see a professional! The ability to heal bones in hours, or even days is reserved for people with immense advancement not really seen at this current time among us.
Do a normal working and focus on the problem area itself, not necessarily the planet or chakra behind it, which although is related, can also complicate the treatment plan. Normal healing workings are more specific to healing itself, but also can flow into the nadis required. While Saturn may rule this area overall, the energy of Uruz would more quickly restore vitality and regeneration.
