Seeing an endodontist is advised.
If all is well after you've finished your antibiotics, I would take a "wait and see" attitude. There is absolutely no reason to jump into getting a root canal at this point, the abcess could just be the result of trauma to the area surrounding the tooth. There probably wasn't any reason to give you antibiotics before now since there were no signs of infection, and you don't want to take antibiotics unless you really need them. If there is a real problem with the tooth, it will let you know and then you can decide what to do. But I wouldn't jump into a root canl or extraction at this point.
if you need a root canal, make sure you ask what they are using. you want gutta percha and specifically say "NO FORMALDEHYDE". A small group of dentist use this stuff against the stance of nearly 99% of the dental community. they don't tell their patients, sometimes even after they injure them. Watch the news story at this website - www.worstrootcanalever.com and say "NO". Nerve damage is the other serious injury from this stuff, but the bone infection that this lady has is horrific. That pink stuff likely has lead and mercury in it too.
Thank you for your comments. The dentist basically told me that because the cold sensitivity has disappeared then it must be damaged nerve/pulp, however everything that I have read says that this usually is accompanied by greater sensitivity to heat, which i do not have. It is still unbearable to put pressure down on the tooth, and my fear is if I leave it and have a minor crack, then once I start using the tooth again it could go down into the root even if it is isn't already there. As mentioned the x-ray did not show anything, but I know that hairline cracks usually don't show, however, I assume that if the pain goes away altogether then should this mean that the tooth is probably okay?
The throbbing pain stopped, but the tooth is still sensitive to pressure after 6 weeks, and I called to see if they thought that a root canal was needed. All the symptoms of still needing a root canal are there, such as percussion pain etc, and my tooth has a smell about it.
So I have decided to have the root canal which I am having tomorrow.
The issue is the tooth is sensitive when i push on the inside of the cusps, and I worry about a crack. After doing this if i push the other way I hear a slight crackling noise, as if there is a crack and the tow sides of the tooth are pushing back together.
I am so worried that I have a split tooth.
I know I will find out tomorrow but I am really worried and would like to know if it is possible for the cusps on either side of the tooth to actually move if there is a crack rather than a actual split throughout the whole tooth. My gut is telling me that movement, even though it is only slight, would only happen if there was an actual split and the two sides of the teeth were actually separated.
no need to answer now, as when they took the filling out the tooth was actually split and so they said the only option at this point was an extraction. :(
My only advice is be careful with dates!!!
I heard that even if your tooth is cracked, they can glue it together or something.
Gluing the tooth back together would be a foolish thing to do, unless of course there were some unknown way to totally sanitize the entire tooth all the way down under the bone, and around the root of the tooth. They would still have to do a root canal. In that process they generally use bleach to disinfect the root cavity, so I suppose it might be possible to clean the entire area that way, but it would be a very risky procedure. That being said, I don't know any dentist that would do such a thing, since that is not a procedure that they are taught in dental school.
