    Thanks for your prompt reply. The tooth does both bother me and at this point I do not want to have the cap replaced due to financial problems. I do ot have dental insurance and just put 15 thousand dollars into a bridge. Can I leave the capped tooth as is for the time being.

  2. Heather says:

    I was told by a dentist I have a cavity under neath my root canal which has abscessed and there is no way to save the tooth. Was told it would have to be extracted. I am not having any pain. Is that true?

  3. Perth says:

    Is it unusual to have a cavity form under a cap less than 3 years after it was installed?

    It is, but you need to analyse your diet to see if you’re eating too many sugary foods

    After my hygentist cleaned my teeth,I had xrays taken.
    I have a small decay under or by my crown.
    I have been referred to another dentist who re-xrayed and said
    I needed a root canal.
    I was told that my dentist then can fix the decay or if need be a new crown.
    I do not understand the procedure,from the root canal,who is not removing
    the crown,and can my dentist fill my decay without a new crown.
    I do have insurance,but the root canal they want me to pay up front,I feel they
    should bill my insurance first,I am about ready to cancel and see if a nother
    dentist would do this for me???

    Dear Sirs I am new to the area, and some dental treatment to address a problem with one of my back molars. To the extent possible I would like to savethe tooth, but if not please could you give me a quote on how much charge for a root canal on the NHS and privately? Many thanks and kind regards

  7. Amari says:

    I need root canal work on one of my teeth (upper right). I currently have a temporary filling in there and I understand that the nerve hasbeen removed. I am looking to acquire quotes from a couple of local dentists. Although I appreciate that every case is different, Would you beable to provide me with the following information:- 1) A quote for both root canal work and a crown. 2) Would the root canal work be carried out by an orthodentist? This is my preference.

  8. Marco says:

    a temporary filling was put in to a crown cavity. The filling fell out last night and it needs replacing. what can i do?

  9. Harry says:

    I had a rootcanal treatment last week on a top front tooth and have several old crowns (top teeth). Considering have replacements and crowning of 8 top teeth so they all look white and more natural than they currently do. help?

  10. Stuart says:

    Hi, I have a crown where the tooth has decayed underneath & I have been told it will need to come out & 1 option would be to have an implant. Could you let me know if you could do this? How much it would be? It’s ny top right 2nd from back. Thanks

  12. Deanna says:

    I am 24 years old and have dreadful teeth (broken, some that are nothing more than a gap, some decayed, yellow/generally unhealthy…) and have a phobia so severe that even talking about visiting the dentist makes me feel shaky. I have not had any dental treatment since I was sedated for many fillings ten years ago. My teeth are getting worse and worsewhich is affecting my confidence and happiness. Thank you for reading, Kind Regards

  13. Brittney says:

    I have had a root canal and cap, the cap it now loose and collecting food particles. Is it hard to get the cap fixed? I really don’t like dentists…..

  14. Kadin says:

    Typically not difficult to get the cap fixed. A qualified dentist will make that go away.

  15. Corinne says:

    I recently underwent implant surgery – 3 weeks ago – and today one of the implant covering/healing caps has come loose. I realise the question was answered before, but do these need to be in place for the entire 3 to 6 month period? If so can a regular dentist refit the cap without too much difficulty?

  16. Adan says:

    If the dentist has the correct driver they can screw it back in easily although its best to get the implant surgeon to check it just in case

  17. Patricia Davis says:

    I noticed a tiny hole at the top of my front upper capped tooth . Can it be fixed without replacing the cap? What all is involved?
