Thanks for the knowledgable response. I truly appreciate it.
I noticed this, .... got a loosened front tooth was a couple of days after when I tried to bite 'really' hard candy or some food. In my guess, that caused 'trauma?' Because most of my upper front teeth need a special care and attention due to my weakened 'gum-line.'
In my dental history,.... my previous dentist I had in my late '20 and early '30, he advised me to brush all teeth good, even brushing gum-line for not getting a cavity. However, I remember very well that I had bleeding in the mouth every time I brushed in the morning. It was very wrong for me to practice, but when I learned about Gum-line and such, it was too late. Only my Gum-specialist explained regarding how important the gum is. As a result, a terrific set of my teeth, both upper and bottom were all gone.
Now, because of horrible experience over excessively hard-brushing, I need to wear a partial denture on my bottom. When I visited the gum-specialist two years ago, he assured me that most of my front part of teeth has a good gum-line. However, why I feel a bit pain on my loosened upper tooth?
Any further inputs on this would be greatly appreciated.
