If your gums bleed when you brush, you have probably decided it is normal. Almost everyone does. It is the single most common thing patients mention and then wave off in the same breath, and it is the one most worth taking seriously.
Bleeding is inflammation, not roughness
Healthy gum does not bleed when a toothbrush touches it. Skin on your arm does not bleed when you wash it. When gum bleeds, it is because the tissue is inflamed and the small vessels near the surface are fragile, and that inflammation is your body responding to bacteria it cannot clear on its own.
At the earliest stage, called gingivitis, this is entirely reversible. Clean it properly, keep it clean, and the tissue settles within weeks. That window is worth catching, because what comes after it is not reversible in the same way.
What changes when it becomes periodontitis
Once the inflammation reaches the attachment holding your tooth to the bone, the body begins to lose that attachment, and then the bone itself. Pockets form between gum and root, deeper than a brush can reach, and the bacteria living in them are different and more aggressive than the ones on the surface.
Bone lost this way does not come back. That is the plain truth of it, and it is why we measure the gum around every tooth and write the numbers down. Those measurements are how we tell whether you are holding steady or losing ground, and impressions are no substitute for them.
The part that reaches beyond your mouth
Gum disease is associated with cardiovascular disease, stroke, poorly controlled diabetes, rheumatoid arthritis, and adverse pregnancy outcomes. The association is well established. The exact mechanism is still being worked out, and anyone who tells you gum treatment will fix your heart is overselling it.
What is not overselling it: chronic inflammation somewhere in your body is not confined to that place, and diabetes and gum disease clearly worsen each other in both directions. If you are diabetic, getting your gums under control tends to make blood sugar easier to manage, and that is worth knowing.
This is the connection Paula McCarthy has spent her career on. She has been a hygienist in this office for thirty-nine years and holds a fellowship through the American Academy for Oral and Systemic Health, and she will happily talk you through where your own gums sit in all of this.
Why we test saliva
Two people can have identical gum measurements and very different bacteria driving them. A saliva test names which organisms are actually present and in what quantity, which changes how aggressively the problem needs treating and how often you should be seen.
It is most useful for people whose gum disease keeps returning after treatment, or who have a family history of losing teeth to it. Coverage varies and many plans do not pay for it, so ask Linda before you commit to it rather than after.
What treatment actually involves
For gingivitis, better cleaning and a proper hygiene visit. For periodontitis, deep cleaning below the gumline, done with the area numbed, usually across two visits. Afterward, maintenance every three to four months rather than every six, because the pockets refill if left alone and the interval is the treatment.
Insurance often covers maintenance but at a lower frequency than you need, which is a gap worth knowing about in advance. Smoking and uncontrolled diabetes both make all of this considerably harder, and we would rather say so than pretend otherwise.
When to come in
Bleeding when you brush or floss, gums that have pulled back, persistent bad breath, or a tooth that feels slightly loose. Any of those is worth a visit, and none of them hurt, which is exactly why gum disease gets as far as it does before anyone acts on it. Call (408) 252-5575, Monday through Thursday.
