Here we go again! (yet another filling!)

[Little tiger]

I went for a check up (I get scared even with just a simple check up) and I've got 6 fillings to do - all 7 and 8's and an impressed dentist saying my teeth were quite well for my age.
I needed a filling down lower left molar (7) and due to costs & a spot of illness etc it's got worse. The cavity has now reached the pulp.
Because I've had no problem with it, no pain, no sensitivity or anything the dentist decided to try to risk a filling with a different dentist there who does more restoration work. If I get pain or anything I'll have to have a root canal. The dentist is fantastic at root canals but the price scares and also the idea of going through a failed filling (again!) scares me.
At my previous dentist I left the dentist did a very deep filling and it failed and I ended up with a very bad infection and I ended up with an abscess with just ended up constantly bursting in the end and going on antibiotics... this all ended up with me going to a different dentist place and getting a root canal and crown.
I'm booked in and I'm having the two lower molars filled at the same time. Apart from that one tooth I don't think the other teeth will be a problem.
So I'm panicking that I might have to go through all that yet again. So any words of comfort and wisdom will be greatly appreciated!

Hi Little tiger,

I just saw that your post had not gotten any replies yet, so jumping in a bit late. Have you had your appointment for the filling yet?
When it comes to your past experience, it's important to know that it does not always have to be that way. If a filling is deep, they put a medication in that is supposed to create a little barrier and help the nerve to calm down. Very often it does work. And sometimes it does not. But even if it does not work, it does not mean that you'll get an abscess. What you described from the last experience sounds terrible.
I wish you the best of luck and please keep us posted

All the best wishes

@Enarete Thank you for the reply it's reassuring! I'm due late next week so I'm on my count down.
I don't think it'll be as deep as my other tooth luckily. I remember having some kind of medication last time and it did failed - the dentist who did that said he just did the same thing on a different customer and it worked so he gave it 80% chance of success so I must be very unlucky!
The fear of it going wrong again and I remember the smell just made me panic. I wasn't good with the sound so I should bring headphones with me next time.
I don't know this dentist as this dentist is new I think but I have more faith in this dental practise than I had with the other one. I just hope I'll be more luckier this time.
