Most people don’t come in because their gums hurt. They come in because something small kept nagging at them. A little blood in the sink. A tooth that suddenly looks longer than it used to. Breath that doesn’t clear up no matter how much they brush.
Gum disease is quiet like that. It rarely announces itself, and by the time it does, it has usually been at work for a while. The good news is that periodontal disease moves through clear stages, and if you know the signs, you can catch it early at almost any point along the way.
Here is what each stage actually looks like, and what to do about it.
First, what periodontal disease really is
Periodontal disease is an infection of the tissues that hold your teeth in place. Not the teeth themselves. The foundation.
It starts with bacteria in plaque, the soft film that builds up along the gumline every day. When plaque sits too long, your body’s immune response to it starts breaking down the gum and bone around the tooth. That is the part that surprises people. A lot of the damage in gum disease comes from your own inflammation, not the bacteria directly.
Left alone, that process works its way deeper, from the gums down into the bone. Bone does not grow back on its own. That is the whole reason stages matter. Each one represents a little more lost ground, and the earlier you step in, the more you keep. You can read more about what periodontal disease is and how it progresses on our site, but the stage-by-stage version below is the practical map.
Stage 1: Gingivitis (the only fully reversible stage)
Gingivitis is inflammation of the gums before any bone is lost. This is the stage you want to catch.
Signs to watch for:
- Gums that bleed when you brush or floss
- Redness or puffiness along the gumline
- Tenderness, or gums that feel a little sore
- Bad breath that comes back quickly
Here is the line that matters most: bleeding gums are not normal. A lot of people have been brushing through pink-in-the-sink for years and assume that is just how it goes. It isn’t. Healthy gums don’t bleed when you treat them normally. If yours do, that is your body flagging inflammation. We wrote a whole piece on why bleeding gums deserve attention because it is the single most ignored early sign we see.
What to do at this stage: this is the easy one. Professional cleaning to remove the hardened plaque (tartar) you can’t get at home, plus tightening up your daily routine, can return your gums to full health. No surgery. No lasting damage. Gingivitis is the one stage that is completely reversible, which is exactly why it is worth acting on the moment you notice it.
Stage 2: Early periodontitis (the damage begins)
Once inflammation moves past the gums and starts affecting the bone, gingivitis has become periodontitis. In the early stage, the bone loss is small, but it has started, and this is the point of no full return.
Signs to watch for:
- Gums starting to pull away from the teeth, forming small pockets
- Persistent bad breath or a bad taste
- Bleeding that shows up more often, sometimes on its own
- Teeth that feel slightly different when you bite
At this stage we measure the pockets between your gums and teeth with a small probe. Anything over about three millimeters tells us bacteria now have a space to hide where your toothbrush cannot reach. That is why the problem becomes self-feeding. The deeper the pocket, the harder it is to clean, and the more the bacteria thrive.
What to do at this stage: the standard treatment is a deep cleaning, known clinically as scaling and root planing. We clean below the gumline, smooth the root surfaces so gums can reattach, and give the tissue a chance to heal tight against the tooth again. Caught here, most people avoid surgery entirely. We cannot regrow the bone you have already lost, but we can usually stop the loss in its tracks.
Stage 3: Moderate periodontitis (the deeper pockets)
Moderate periodontitis means the pockets are deeper, more bone is gone, and the infection is more established. You may start to notice the effects yourself rather than relying on a checkup to find them.
Signs to watch for:
- Gums that have visibly receded, making teeth look longer
- Increased sensitivity, especially to hot and cold
- Teeth that feel a little loose or have shifted
- Pus or a bad taste near the gumline
- Pockets in the four-to-six millimeter range
This is also the stage where the connection to the rest of your body gets harder to ignore. The same inflammation attacking your gums is linked to diabetes, heart health, and other systemic conditions. If you are managing any of those, your physician is part of this conversation too, and it works both directions. Gum infection can make blood sugar harder to control, and poorly controlled blood sugar makes gum disease worse.
What to do at this stage: deep cleaning is still the foundation, sometimes paired with targeted treatment of the deepest pockets. We watch closely, because moderate disease can hold steady with good care or keep advancing if it is left alone. Regular periodontal maintenance, not just twice-a-year cleanings, becomes part of your routine.
If anything in this section sounds familiar, that is the moment to act. You can book a consultation with Dr. Cherry and get an actual measurement of where your gums stand, rather than guessing from symptoms.
Stage 4: Advanced periodontitis (saving what we can)
In advanced periodontitis, a significant amount of the supporting bone is gone. Teeth may be loose enough that you feel them move, and the goal shifts to saving what can be saved and rebuilding a stable foundation for the future.
Signs to watch for:
- Teeth that are noticeably loose or moving
- Gums that are painful, swollen, or oozing
- Changes in how your teeth fit together when you bite
- Pockets deeper than six millimeters
What to do at this stage: treatment is more involved. Osseous surgery lets us clean deep below the gums and reshape the bone so it can be maintained. In some cases we can use regenerative techniques to encourage new bone where it was lost, which is something periodontists are specifically trained to do. When a tooth truly cannot be saved, we plan the removal carefully and map out how to rebuild, because what comes next matters as much as the extraction itself.
Advanced does not mean hopeless. It means the margin for waiting is gone.
What this looks like in our office
Here is the part we wish more people knew. You do not need a referral or a scary symptom to come see us. If something feels even slightly off, you can come in for a basic check, and we will look at everything.
A periodontal evaluation is not just a glance at the tooth that is bothering you. We measure the pockets around every tooth, look at the bone on your X-rays, check for recession and movement, and review how your gum health connects to the rest of your body. It is the kind of thorough look that catches the early stages most cleanings miss. Often someone comes in worried about one spot and we are able to reassure them it is healthy, while flagging something they had not noticed yet.
That is the whole advantage of seeing a specialist. We are looking at the foundation, not just the surface.
When to come see a periodontist
Book an evaluation if you notice any of these:
- Gums that bleed regularly when you brush or floss
- Gums pulling away from your teeth, or teeth that look longer
- Persistent bad breath that brushing does not fix
- Any tooth that feels loose or has shifted
- A dentist who has mentioned “deep pockets” or recommended a deep cleaning
And one quieter signal worth knowing: if your general dentist has been doing a deep cleaning every year or so, that is a sign the disease is not actually under control, and it is worth a periodontist taking a look.

Frequently Asked Questions
Q: Can periodontal disease be reversed?
A: Only at the gingivitis stage, before any bone is lost. Once it becomes periodontitis, we can stop the progression and stabilize your gums, but bone that is already gone does not come back on its own. That is why acting early makes such a difference.
Q: Does a deep cleaning hurt?
A: We numb the area first, so the cleaning itself is comfortable. Some tenderness afterward is normal and usually settles within a few days. Most patients are surprised by how manageable it is.
Q: How fast does gum disease progress?
A: It varies a lot from person to person. Things like smoking, diabetes, genetics, and daily habits all affect the pace. Some people stay stable for years, others advance quickly, which is why regular monitoring matters.
Q: My gums only bleed sometimes. Is that still a problem?
A: Occasional bleeding is still your body signaling inflammation. It is worth getting checked rather than waiting to see if it gets worse. A basic evaluation can tell you whether it is early gingivitis or something more.
Q: Do I need a referral to see a periodontist?
A: No. You are welcome to come in directly for an evaluation any time you have a concern, even a small one.
