had ones done with a local only was not that bad just be careful with that you eat as you don't feel it as much if something is stuck downstairs there like a seed or chip. years later had something stuck didn't know it and snapped the screw and lost the tooth without ever feeling it. bended up having to have the tooth pulled and getting a implant for way more money.
Even had the tooth pulled with only a local was not that bad my jaw hurt from holding my mouth open than the tooth than the tooth itself
