Feeling after permanent filling

[Gayan]

First thank you all for giving me a chance to post here. I got damaged teeth so i got a permanent filling on 2018-03 (nearly). After looking at x -ray(see the images attached) doctor said it didn't went to the bottom so we do a permanent filling and then if it is not working then we go for nerve filling. So after the permanent filling whenever i do mouth washing i feel some weirdness in that teeth(like water go inside the teeth) and whenever i touch the teeth i got a little pain (not a big btw). anyway i waited for nearly for ten months and went to see dentist. Dentist told me that there is a broken place in that teeth that is why i got that weired feeling. So he again did permanent filling to that broken place(said old filling is good and will do nerve filling when necessary). From that day i don't get that weird feeling when there is water in my mouth. But i got little weirdness after i wake up(may be due to saliva) now. Plus weird feeling(little pain i think) comes and goes time to time from that teeth and when i touch the teeth same little pain comes.
Please let me know what to do. Can I save this teeth? Do i have to do nerve filling? Any other way around without doing it? I hope i explained every thing here. Thanks in advance.

What country are you from? I see 3 teeth that are damaged and need fillings. After fillings, the teeth may feel strange. If your tooth feels cold, it is normal, the nerve is working. If your tooth feels intense pain that can wake you at night, your tooth nerve is damaged. If you have swelling next to your teeth, the tooth nerve has died and became infected.

Very much thanks for replying. I highly appreciate it. I am from sri lanka. I went to to see another dentist and i was told that i get this feelings because the filling is a metal one and the filling is deep one near to blood vessels. I was asked to take x ray (which is here https://ibb.co/hR5Ntr6 and you can get which teeth got the filling by here https://ibb.co/dpSSD9T ) and informed me that no need to go for nerve filling (told me that after nerve filling teeth will break after 10-15 years). But dentist cleared the gap between two teeth( gap between the teeth with filling and other teeth). So I get the feeling from this teeth for whole time(well most of the time). Can't say it is a pain. How can i get away from this feeling? Is there anything I can do rather than waiting for nerve filling? And no i don't have intense pain in that teeth and no swelling next to that teeth. Thanks in advance!

Unfortunately your cavities are pretty big and you may have sensitivity after the filling. Hopefully the sensitivity will lessen over time. The only way to rid of the sensitivity is to do a root canal or pull the tooth.
