Ongoing irritation where dental crown was placed?

This is not a normal thing that you were facing same problem after 3 years of the treatment. It needs to properly examine your teeth to find out the problem. I would recommend you to consult some other dentist regarding for the treatment.

Msgorgeousgeek,Bleeding gums are never considered "normal", if you know what I mean.  Gum irritation and inflammation can be caused by a number of things, but its always better if it isn't there.  So, there may very well be a problem with the crown and it could be causing a problem.  A good dentist should be able to figure out the problem in a few minutes of diagnostic evaluation. The good news is that generally if a crown needs to be replaced, it may not be as involved a process as it was when it was first done.  Especially now that digital impressions are available.  Removing the old crown takes very little time and then cleaning up around the preparation and then a few pictures and you are finished. I have attached a short video on the digital impression process below.Warm Regards,

Hi:My first suggestion is to consult with a periodontist to find out the cause of the irritation before deciding on changing the crown.Best,Dr. Maddahi

Easy bleeding and puffy red gums are definitely a sign of inflammation.  The inflammation could be caused be one or several factors:1.  Crown overhang or open margin2.  Excess cement which was not removed3.  Plaque or calculus accumulation 4.  Food impaction from light or open contact between the teeth. 5.  Allergy to the crown or cement I would return to your dentist with your concerns
