High spacing in between root canaled tooth.

I had a root canal about 8 days ago.(upper left side,large tooth in middle).There is still a high spacing in between this root canaled tooth,that im able to reach(and was able to reach before the root canal)with half of a razor blade in order to remove food particles that get stuck in that pocket or hole.The spacing between this tooth goes quite high into the gums and im wondering if my dentist overlooked this area and forgot to fill it in?(although much less food gets stuck there compared to before the root canal).There is still some slight soreness when I chew hard and dry foods on that tooth but it seems its getting better as the days go by.(there was more pain the first 2 days after the root canal,but its much better now).

the tooth probably needs to be restored with a crown to reproduce the proper contour of the tooth.

Thanks for replying. I dont wish to have a crown.My dentist informed me that the high spacing is normal and sometimes appears near a decaying tooth.But he didnt take a second x-ray to confirm how high the spacing was.I could only reach it with half of a razor blade(adults and kids dont try this at home),and im able to remove some food particles that flossing cannot reach.When half of the razor blade reaches that high spot between my teeth,it feels like the blade is inside a pocket or hole in the gums right next to the tooth the was root caneled.Is it possible that my dentist forgot to fill in this hole in the gums? Thanks.

most teeth that have root canals should have crowns to help prevent fracture. teeth that have had root canal can fracture becasue they are brittle, and have ben holowed out to do the root canal in the first place. be careful chewing on it. If the spacng you describe ws there before the root canal procedure, then perhaps it may not be able to be totallly rectified-- you may have periodontal isues that are causing that. however, a crown should be able to restore some amount of contour to the tooth. that is part of what a crown does.

I forgot to mention.A crown would not reach that high spacing(pocket or hole in gums)next to root caneled tooth.

Maby perhaps dentists should fill in a hollow tooth with a stronger filling material such as a porcelain filler,instead of having to grind the tooth smaller in order to fit a crown thats made out of porcelain.This way patients dont have to pay double to have a crown as well,when the porcelain filled tooth may be strong enough.

when a filling goes inside a tooth it weakens it no matter what material is used. crowns work becasue they cover and protect the tooth.
