Why does my filling on my tooth hurt when something cold goes on it like a cold !

well
what i think ( because my sister experienced this before) is that ur tooth filling is done with a weak or non conciounce dentist because when it happened to my sister it was because of this
the filling was very deep
this means that the hole u filled was deep that it reached what we call in arabic letterly (nerve) i don't know what it means in english but in letterly transslation it's nerve
so now the filling is weak and this cold drink os reaching the nerve
so u should clean ur tooth again and put new filling
i wich i helped

You could have a cavity around where the previous filling or it may just be that your tooth is sensitive. They have toothpaste for sensitive teeth that you could try but, I suggest seeing your dentist to find out what is really going on with that tooth.

Some people just get super sensitive after a filling. I know I do. For about a month after a filling, its strictly eat and drink on the other side. It will get better but sometimes never goes away.

thats bad
