Dentist Questions Deep cavity

I have severe pain in my deep cavity filling. What could this be?

I have severe pain in my deep cavity, which has been extremely sensitive to the cold from ever since I got the filling done. I was unable to bite on this teeth and had shooting pain all through the right side of my jaw and mouth. Yesterday after I brushed my teeth it even started to bleed. Why is this happening? Any Advice?

See a dentist. You may need a root canal on this tooth.
Too involved to tell from this narrative, you should go back to the treating dentist.
When a cavity is deep, it is close to the nerve. If it is too close, the nerve becomes inflamed/angry and can be the symptoms you described. There is a chance you will need a root canal to save the tooth. You should return to your dentist and have it evaluated.

Hope this helps,

This pain could be caused by the tooth beginning to abscess or from a fracture in the tooth. It is always best to have these things looked at. An X-ray and symptom review is needed.
When did you have the filling done? You need to take an X-ray to see how deep the filling is. You might need a root canal.
Couple things that could happen there number one the feeling is too high to function with your bite and is keeping the tooth hypersensitive this situation is usually solved buy some simple adjustments to the filling
Number 2 it is possible that it was really deep and too close to the nerve which then keeps the sensitivity likelihood higher in those cases a dentist usually places and under laying material to prevent your nerves from irritation
Number 3 it is possible that you cavity was too deep and that upon doing work on that tooth it may have gotten infected by the bacteria that has caused your deep cavity and in that case you will require a root canal or an extraction
Sometimes the nerve in the tooth can get irritated when you get a deep filling done. Often times the irritation is temporary and the nerve settles down after a while. In some cases you may need a root canal if the nerve doesn't settle down. I would recommend checking back with the dentist that did the filling as sometimes all you may need for everything to settle down is a bite adjustment.
Go back to your dentist and discuss the pain that’s troubling you. You may need adjustment to the filling or in the worse case scenario, a root canal treatment.
Obviously, you had allowed this tooth to decay severely, which required a great deal of damaged tooth structure to be removed. The decay was probably close to being in the pulp/nerve. It is no surprise that the tooth is cold sensitive, but should be getting less sensitive as time goes by. If the sensitivity is not getting better, you need to go back to the dentist, as a root canal may be necessary to deal with the issue. As for the bleeding, that is most likely from the gums not the tooth and is a sign that you are probably not flossing and taking care of your teeth as you should, which is why you had the deep cavity in the first place. Start flossing and brushing.
Hi there. Severe pain can be to nerve involvement as every tooth has a nerve inside it. If the cavity goes deep close to or in your nerve, it gets inflamed and can cause a severe tooth pain. In that case, option to save the tooth would be root canal treatment.
Deep fillings tend to be in close proximity to the nerve and may cause pain. I would go back to your dentist and let them know this is happening so they can evaluate and propose new treatment options. The bleeding may be from irritated gums due to possibly not brushing the area as well if you’re in a lot of pain or it can also be from having a cracked tooth.

It may develop into a root canal problem. Deep fillings can cause persistent sensitivity for many months. Avoid chewing on it, and avoid hot and cold to give it a chance to heal. The bleeding can be from a rough spot.
Get the bite checked by the dentist. Make sure it is not hitting harder than the other teeth when you bite or clench and grind forward, back, left and right. You may need root canal if pain does not subside in upcoming weeks. The tooth is like bone- it takes 6-8weeks to heal. If pain is intense for 1 minute, wakes you up at night, comes on out of the blue and continues for 1 minute, you may need the root canal or extraction. Get x-rays and get cavities restored before they become so deep and you will have less problems, hopefully, in the future. This is not medical advice, it is my opinion.
It is either nerve exposure or very close to it. In either case, you need to do root canal, where the nerve of the tooth is removed.
The pain you are describing can only come from a few different problems. First, the filling you just had done may not have been adjusted properly leaving it high in your bite. If it is sticking up higher than the adjacent teeth, even by the width of a strand of hair, it will get pounded and hurt when you bite and even to the cold. Another possibility is that the cavity was so close to the nerve that the nerve has started to die. This will require a root canal to save the tooth and likely a crown. You should contact the dentist that did your filling and ask them to evaluate it. Best of luck!
This could be from several causes, the most likely being that the deep filling was close to the nerve. Also, it could be that the filling is slightly high. I would return for a follow-up appointment to assess the reason: a high filling, something caught under the gums, or a near exposure of the nerve.
If the filling is very deep it is possible to have cold sensation. This usually improves. If it does not the nerve inflammation from doing the filling is not going away. If the nerve inflammation is not suppress it can turn into an irreversible pulpitis that will require a root canal to keep the tooth. With the pain you describe that may be the case, but you should have it evaluated by a dentist to make sure. Some times if the bite is off you can get persistent pain and muscle spasms due to the incorrect bite
It's one of two possibilities that come to mind one being that when your tooth was restored the feeling that is new maybe in hyperocclusion causing referred pain that you described. Your dentist can adjust the feeling so that it matches better with the opposing tooth and is comfortable when you chew so is not interfere with pain receptors located in the nerves. The other possibility maybe that not all that all the Decay may not have been removed from the tooth for fear of breaching the root canal itself so a sedative filling could have been placed in order to allow the tooth to recover and another appointment will be needed to further determine the more permanent restoration such as a crown. Amount amount of discomfort that goes for only a few days is quite normal especially if the filling was abnormally large in size but for it to continue past that point indicates further problems that need to be investigated by your dentist.
A very deep filling may be irritating to the nerve of that tooth making it temperature sensitive and sometimes bite sensitive. If the symptoms are getting worse I recommend you have your dentist evaluate the tooth. The tooth may need a root canal if the pain appears to be irreversible.
Your deep filling sounds like it is close or in the nerve of  the tooth. Based on your symptoms, you probably need a root canal treatment followed up with a crown. 
Go back to the doctor that did the filling. The filling just might need adjusting.
There could be an infection starting and my need a root canal. These are the most common reasons.
