I really REALLY need help with this dental question?!

So i go in for fillings, and the dentist comes in and looks at my teeth and says some are decayed and need to be pulled. Keep in mind now , that this has been known for months and I have an oral surgery consult in 2 weeks for my wisdom teeth . He progresses to say to me " We should pull both teeth that need to be root canaled also because its very expensive to get that treatment done ". ARE YOU KIDDING ME. He wants to pull my wisdom tooth thats already in on my bottom left side, along with 2 molors RIGHT NEXT TO IT. Leaving me with 1 mollar on my bottom left half. Im 25 years old and your telling me its better to pull 2 teeth that need to be root canaled then try and help me with a payment plan to SAVE MY TEETH. The whole point of a dentist is to SAVE MY TEETH. Keep in mind this is a public dentist , and my last dentist who was private told me " its not a good idea to pull those teeth since they are important ". So granted I made an appointment with him for thursday to talk this out. He knows i know to the public dentist since its free for deep cleanings , fillings and all extractions. I want him to do the root canals and the braces. Not to mention there were extremly nice and told me thats plenty of payment plans. THE PUBLIC DENTIST SAID NOPE NEEDS TO BE PAID IN FULL RIGHT AWAY

BUT WAIT ITS NOT OVER , THIS PART MADE ME ANGRY


" I think its a better idea if we wait to do the 2 fillings until after the teeth are extracted " ... MY TEETH WITH THE CAVITIES ARE ON THE RIGHT SIDE OF MY MOUTH. ARE YOU KIDDING ME! What in the WORLD does me having teeth needing to come out have to do with me getting my fillings TO STOP THOSE TEETH FROM GETTING BAD AND NEEDING ROOT CANALS. Im shocked that i wasted my time waiting for this filling appointment just for them to say " wait till the extractions are done ". WELL THEN WHY DID U MAKE ME COME ANYWAY WHEN U KNEW I NEEDED EXTRACTIONS. I truly believe that he was overbooked , considering i waited 45 mins to even see him cuz he was doing another persons teeth at the time. I was in shock and legit mad even more because i took Xanax to calm me down before i went, which is now a waste , and i took 1mg , more then last time cuz he mentioned pulling my teeth. IM SO FED UP

IM SO MAD. This whole thing sounds completely wrong.
