Dealing with gum disease need tooth extraction

Helloo all!!
Hi, I am dealing with a gum disease. Two days before, I saw blood while brushing. I thought it was due to the injury occurred in the mouth while brushing. The same thing happened yesterday. Then, I looked in the mirror and found that my gum is swollen in the left molar region. When I took a visit to a nearby clinic the dentist told me to take care of my oral hygiene with consistent dental cleanings and through oral hygiene habits. I followed his words for a week and then I was back to the normal unhealthy habits. Now my tooth’s condition is very bad and I’m tensed whether the dentist will suggest for a tooth extraction treatment ( http://www.emergency-dental-365.com/procedures/emergency-tooth-extraction/ ). My dentist suggested a tooth extraction and it is scheduled for the coming week. I’m little conscious about it. Kindly pray for me.
