I am not sure what a biological dds is but went to see dentist who ruled out tooth, gum and sinus problems
A biological dentist is one that treats holistically. They take more 'care' (generally) than a regular dentist when it comes to replacing fillings, etc. (so there is minimal mercury exposure) and they are generally against root canals.
That's simplifying it...but just to give you an idea.
