Sorry to hear about your situation.
Although what you're experiencing is not unheard of, it certainly isn't common. What does seem odd to me is that you've been fine for 25 years and suddenly in the past 2-3 months, you're on your 4th bone spur.
My recommendation/advice is as follows:
Ask your general dentist for a referral to have a "Cone-Beam CT Scan" done of your upper and lower jaw. This is a relatively new CT Scan that is very low in radiation, but can provide an extreme detailed, 3D image of your jaw bones. Then find a periodontist
(gum specialist) to seek further treatment if the Cone-Beam CT Scan comes back detailing additional bone spurs. Hopefully the periodontist will be able to perform gum surgery
to remove any additional spurs and properly recontour the bone/cortical plate to prevent future spurs.
The reason the Cone-Beam CT Scan is important because it provides additional information than the standard 2 dimentional X-rays so the dentist (periodontist) can see exact "splices" along your jaw where the spurs have been forming to determine what is going on and how to properly treat it.
The Cone-Beam CT Scanner is being marketed by 2 companies (Galileos and I-Cat) and unfortunately costs ~$200K so most general dentists won't have it in their office. Which is why I suggested asking for a referral (most likely an oral surgeon) to have the scan made.
