Quick dental check-up

I had a quick dental check-up yesterday. Actually, I thought the dentist will start to do the root canal treatment, because with my first check-up, she told me that I have a root canal infection that needs to be treated with my next appointment. After a day with what the dentist did with my first check-up, I felt a terrible pain with my affected tooth. Just imagine, I need to wait a week just to book for another appointment because it's only every Wednesday that she's there at the clinic. I don't like the idea of going to another clinic and face another dentist. I want to stick to one that I already used to. So the pain started Thursday and it last until Monday. The pain only stop after taking pain-reliever every six hours. I'm not used to take medicine like anti-pain and etc., but that's the only choice I have to do just to get rid of the worst pain. I can't sleep because it bothers me a lot. With five days of pain, I lose weight which is too bad because I'm working on gaining weight. Tuesday, the pain slow down even without pain-reliever until yesterday. So the dentist check my tooth and I explain how I felt. The abscess that keeps coming back and the yucky pus which is always present.
You know what the dentist told me? I have to give up my tooth. It has a crack inside that let the bacteria gets in which is causing the pain. Root canal can do nothing. Tooth extraction is the solution. I felt bad. I don't want to loose my tooth. Are your teeth guys still complete. Is it still pair with the other side? Oh no. I hate the consequences if my tooth being pulled. All my teeth will start to move and the alignment will be broken. Do you know what it means? Maybe some of you don't know the reason why losing a tooth is not really good especially if it's a big one. It's a big deal for me. I don't want to lose even a single tooth. I'm always careful with my oral hygiene but why this is happening to me? Arrrg!
This coming Oct.22, I have another 1hour appointment with my dentist. She will pull it out.
Are you familiar with dental implants? A surgery that will replace a missing tooth with a false tooth. The procedure is so scary. I don't know if I'll take the risk. I'm so scared. That's an option anyway and I need $3000-4000 for that procedure. Can you imagine that? I was given an information about dental implants. I'll gonna post and share the information later on.
I'm still hoping that I can till keep my tooth. I'm feeling fine now. Yesterday was just a free check-up because she only look at it and told me what to do next. I was given an anti-biotic prescription in case the pain will come back. I didn't buy it because I'm feeling okay. No more pain, no more abscess and no more pus. I'm still hoping that I can go for a root canal treatment. I want to save my tooth. Oh dear...please.
