Gum disease has an unfortunate reputation for being a one-way road to losing teeth. In practice, teeth with substantially reduced bone support can be kept comfortably for decades once the disease is under control.
What makes that possible is catching it and treating it properly. Periodontitis is the loss of bone and attachment holding teeth in place, caused by bacteria in plaque but driven largely by the body's inflammatory response to them. Which is why two people with similar plaque can have very different outcomes.
The difficulty is that it rarely announces itself. Gums may bleed on brushing and breath may not feel fresh, but bone loss produces no sensation at all. By the time teeth loosen or start to drift, a good deal of support has usually gone — and bone that has been lost does not regrow on its own.
Treatment cannot restore what has already gone. What it can do is stop the disease progressing, make the mouth genuinely cleanable, and keep teeth that would otherwise be lost.
What a specialist assessment adds
Periodontal disease is one of the areas where the difference between a routine check and a full assessment is largest.
A comprehensive assessment measures every site around every tooth, establishes a stage and grade diagnosis, identifies which teeth are genuinely at risk and which are not, and produces a written plan you can keep. It also gives you a realistic prognosis for individual teeth — which is exactly the information you need before spending money on crowns, implants or cosmetic work that depends on those teeth providing a strong foundation.
