No kidding (need a new dentist)
Thank your for your replys.
What would your first choice be? Just curious? I am immune to PenVK.
That is called a loading dose, and it so that it brings up the A/B to a therapuetic level in your blood stream. Erythro would not be my first choice but it would work probably.. Sounds though, like you should find yourself a new dentist.
Seeing a periodontist is advised.
