Why is my Tooth So Sensitive Still After 3 Weeks of Filling?

My dentist said the filling is deep. But every time eat or drink something cold my lower jaw seems to hurt really bad. Is it always going to be like this?

Pain after deep filling

Sensitivity after a filling is placed can occur for a number of reasons. The most common is a high bite. When you are numb, the bite may feel okay but be a little high.  When the anaesthetic comes out, the tooth may become sensitive.  Most restorations placed are now bonded, so this step helps to protect the nerve.

To see if the issue is due to a high bite, check if it "feels like something is in the way when your teeth come together?"  Also, does the opposite side feel normal?  Call your Dentist & have him/her check your bite. A very important thing to do as well is to check the chewing cycle. Put some gum or wax on the opposite side to where the filling was done, chew & mark with a ribbon any interferences on the filling while chewing.

When a filling is deep & the bite is not high, you may feel cold initially, but this shouldn't last long & the tooth will heal. If the bite has been adjusted & you still feel the sensitivity with temperature change, a root canal will be needed.

From what you are describing it sounds like you have may have either a high bite which needs adjustment or your tooth may need a root canal due to how deep the restoration was. Either way I would call your dentist and let them know what your problem is and they will advise you what is needed to be done

Two possibilities:

- The bite needs adjustment - see your dentist. 

- The filling was very deep - the sensitivity will either get better or it won't.  If the tooth doesn't heal on its own, you may need root canal treatment.  Don't worry about that - root canal treatment in 2012 doesn't hurt, just a long and boring appointment.

Either way, your dentist will advise you on what to do, but if the bite is ok, it's just a matter of time to see how the tooth responds.  This does happen, especially with deep fillings.

So there are a couple things you should do - first go back and see your dentist and have him or her check your bite - sometimes if a new filling is just a little bit "high" it may cause your tooth to have trauma when you chew/bite and in time that tooth becomes very sensitive.  After that, have the dentist check the vitality status of the nerve - sometimes when you have a large cavity or filling, the tooth (nerve) may die over time and you will have a lot of discomfort when you chew - if this is the case, you need a root canal.  Finally, sometimes when a filling is very deep, it irritates the nerve of the tooth and if this does not go away over 2 weeks to a month it is probably time for a root canal.  Next step is to go back to your dentist ASAP.  Good Luck

Please return to your dentist and have him check your bite. If you are hitting the filling incorrectly, it will prolong the sensitivity. Also, your nerve may have been affected by the depth of the restoration.
