Gum disease??

[klindzi]

Iv had a really bad start with my teeth from younger when iv had fillings on 30% of teeth. I also grind/clench sub conciously for best part of 20 years which has had an impact on my roots. Iv been quite good with brushing teeth and flossing etc. Now my dentist has said that my roots are showing signs on trauma from grinding. I have worn a mouth guard at night. 2 molars either side of lower mouth have gums receded and started oozing about 4 weeks ago, iv had a round of antibiotics that haven't helped and a deep scale clean. Iv also just had a full mouth xray to check teeth fully to check whether infection has hit the root etc. Now dentist has not got back to me regarding next steps and iv been chasing her can dentist provide any advice as I'm really worried il lose my two teeth if it's not treated quickly.
