Yellow drainage post tooth extraction?

[Ck022492]

I had 2 teeth extracted over 8 weeks ago, the roots were right up against my sinus, now only
Only th right side I have a horrible smell in my left sinus and uncontrollable drainage from my left nostril and noticed yellow drainage coming from underneath a crown in the same area of the extractions... any thoughts?

You likely have an oral -antral ( sinus) communication ; i.e., your roots were likely anatomically in the sinus resulting in a "hole" between your mouth and the sinus leading to a sinus infection.. See an oral and maxillofacial surgeon for eval and treatment
