It's more the gums that are concerning - periodontal disease is often defined (without any actual proof) as one of the culprits. It certainly is suspicious in a good percentage of those who've had endocarditis. Without question, it has some effects on health. So it's something that should be corrected, no matter what reason is cited.
And no, you don't have to be piggish to get it, or never brush your teeth. I've had extensive gum surgery for periodontal disease, and I always brushed my teeth before.
It is treatable. It's not pleasant, but when you're done, you go back to having 15-minute cleanings with no pain and no blood. And no more lectures from the dentist or the dental technician...
But, it's not cheap. And it's painful healing, as you're going through it. Oddly, I remember the pain from the many novacain shots used more than the pain from the actual surgery areas. It was like someone had left a dotted line of pain points across the inside of my mouth.
I was left with many of my teeth, but some gaps. Since my surgery, I had implants put in for some that were missing, and have two upper pins to have put in next year. That involves a "sinus lift," a procedure for which I will spare you the description. The entirety of the process will take almost a year of procedures and waiting. However, if it's anything like the implants I have now, it's like getting a second chance with your own teeth when you're done. My 18-month experience prior to that with a small denture was painful and horribly unsuccessful. I'm neither squeamish nor picky: it just didn't work. The implants are terrific, and they feel completely normal.
Again, it's not cheap.
I put away money in my pre-tax medical fund to cover it, which is like getting a discount equal to your tax rate. It's about the best you can do, unless you find some kind of a program, or have upper-tier-type dental insurance. My dental insurance declined to pay for the implants. I found out that they pay for bridges, and made the case that they should pay toward the implants what they would have paid toward a bridge, if one could have been made. They finally agreed to that proposal. It didn't go too far, as I also have a $1500/yr limit, and had gone through much of the rest that year already.
Ross, any way you can wangle it is better than none.
Best wishes,
