Gum disease is quiet until it isn't.
Most people who come to us for their gums weren't in pain — they noticed a little pink in the sink, a bit of recession, or breath that wouldn't quit no matter how hard they brushed. Periodontitis rarely hurts until it's advanced, which is exactly why it's so easy to ignore for years. Below is everything you'd want to understand before treatment, in plain language — including how we prove, with a number, that it worked.
Your gums bleed
Pink in the sink when you brush or floss — the single most common early sign, and the one most people talk themselves out of worrying about.
Something feels off
Persistent bad breath, tender or receding gums, sensitivity at the gum line, or a tooth that feels faintly loose — small signals that add up.
You've been told to 'watch it'
A previous office mentioned 'a little gum disease' and left it there — no charting, no plan, no follow-up number. That's not a plan.
How does periodontal treatment help me?
Stop the bone loss — and keep the teeth you have.
Gum disease is a bacterial infection of the tissue and bone that hold your teeth in place. Left alone, it slowly destroys that support and teeth loosen. Periodontal therapy removes the bacteria and hardened tartar living below the gum line, calms the inflammation, and — where the disease has already reached the bone — halts its progression. It won't regrow bone you've lost, but it stops the loss and protects everything still standing. The earlier we start, the more we save.

Gingivitis vs. periodontitis — they are not the same
The distinction is the whole game. Gingivitis is inflammation of the gingiva — the gum tissue — with no bone loss. Gums bleed, look red, and feel tender, but the underlying support is intact, and it is fully reversible with a cleaning and better home care. Periodontitis is gingivitis that has progressed: the inflammation has crossed into the periodontium, destroying alveolar bone around the tooth root, and the sulcus between gum and tooth has deepened into a true periodontal pocket of 4 mm or more. That bone loss is generally permanent — but it can be stopped, and stopping it is the entire goal of treatment. The earlier the diagnosis, the more bone we save. This is also why a routine teeth cleaning is a screening opportunity, not just a polish.
Why we chart before we treat — the number that matters
Periodontal disease is measured, not eyeballed. Before any treatment, we perform full periodontal charting: a calibrated probe records the pocket depth at six points around every tooth, along with bleeding points and recession. That gives us a map of exactly where disease is active and how deep it runs. It also gives us a baseline number to measure against later. According to PubMed, over 47% of U.S. adults aged 30 and older — roughly 64.7 million people — have some form of periodontitis, and among adults 65 and older, 64% have moderate or severe disease. Most of them have no idea, because early periodontitis rarely hurts. Charting is the only reliable way to find it before it costs you teeth.
How scaling-and-root-planing works
Scaling-and-root-planing (SRP) is the foundational periodontal treatment — sometimes called a deep cleaning. Under local anaesthesia, ultrasonic and hand instruments remove tartar (calcified plaque, also called dental calculus) and the bacterial biofilm from the root surfaces below the gum line, then the root surface is planed smooth so plaque has fewer places to re-anchor. We typically split SRP across two visits — one side of the mouth per visit — taking roughly 60 to 90 minutes each, which keeps you comfortable and lets us work thoroughly. Where specific deep pockets need extra help, a locally-delivered antibiotic can be placed directly into the site. For very inflamed or fibrotic tissue, our Solea laser can assist with decontamination and is often gentler on the surrounding gum.
Re-evaluation — proving the treatment worked
This is the step most offices skip, and the one Dr. Shi insists on. Six to eight weeks after SRP, we re-chart the same six points on every tooth and compare them to your baseline. In a successful case, pockets shrink and the bleeding sites quiet down — the tissue has re-attached and the inflammation has resolved. If the numbers haven't moved, the treatment wasn't enough, and we adjust rather than assume. Periodontal care is one of the few areas in dentistry where success is a measurable before-and-after, not a matter of opinion. Without that second measurement, no one can honestly tell you it worked.
Your next step
Wondering if gum disease treatment is right for you?
A free consultation includes an exam and a written plan — no pressure, no upsell.
Periodontal maintenance — the long game
Once active disease is controlled, you transition from treatment to periodontal maintenance — typically every three or four months rather than the standard six. The shorter interval exists for a real biological reason: the bacteria removed during SRP begin to recolonize the deep sites within weeks, and the deeper pockets periodontal patients carry shelter bacteria more stubbornly than healthy gums do. Maintenance is a distinct procedure from a routine prophylaxis — it goes below the gum line at those vulnerable sites — and it's billed differently. Skipping it is, by a wide margin, the most common reason periodontal disease comes back after a successful start. Keeping stable patients stable is the whole aim of our preventive dentistry program.
Your gums and the rest of your body
Periodontitis isn't only a mouth problem. Bidirectional associations between gum disease and cardiovascular disease, diabetes, and adverse pregnancy outcomes are documented in the literature, and for diabetes the connection is especially well-supported. According to PubMed, a 2022 Cochrane systematic review of 35 randomized trials found that treating periodontitis produced an absolute reduction in HbA1c of about 0.43% (4.7 mmol/mol) at three to four months in people with diabetes — a clinically meaningful improvement in blood-sugar control from cleaning the gums alone. The takeaway isn't alarm; it's that healthy gums and a healthy body pull in the same direction, and treating one often helps the other.
Risk factors — what makes gum disease worse
Some risk you can't change: genetics, age, and certain medical conditions all tilt the odds. But the largest modifiable risk factor is tobacco. According to PubMed, a 2025 Mendelian-randomization analysis estimated smoking carries an odds ratio of roughly 1.74 for developing periodontitis — a substantial, causal-direction increase — and smoking also masks bleeding, so the disease can advance silently while looking deceptively calm. Poorly-controlled diabetes, certain medications, hormonal shifts, and inconsistent home care all raise risk as well. None of this means treatment won't work for you; it means we tailor the plan and the maintenance interval to your specific risk, which is exactly what the charting tells us.
5 mm
When surgery becomes the right answer
Most periodontal patients never need surgery — SRP plus disciplined maintenance controls the great majority of cases. But if pockets stay at 5 mm or deeper after thorough SRP and good home care, or radiographs show continued bone loss, we coordinate a surgical consultation with a periodontist. Surgical options include flap surgery to access and clean deep roots, regenerative procedures using bone graft material and a barrier membrane, and crown lengthening when restorative work needs more tooth exposed. Where the problem is recession rather than active infection, minimally-invasive pinhole gum rejuvenation can restore the gum line without traditional grafting. The point is a coordinated hand-off with a clear reason — never a vague wait-and-see.

Concerned about comfort, bone, or cost?
These are the questions a consultation answers directly. Dr. Shi reviews your 3D CBCT scan, evaluates your bone and candidacy, and outlines your options, treatment timeline, and estimated cost — including what your insurance may cover.
Thinking about it
The questions we hear first
How do I know if I have gum disease?
Bleeding when you brush or floss, gums that look red or swollen, persistent bad breath, gum recession, sensitivity at the gum line, or teeth that feel slightly loose are all signals. But many people have no symptoms at all in the early stages — periodontitis is famously quiet. The only reliable way to know is periodontal charting at a dental visit, where we measure the pocket depth around each tooth and record where the gums bleed. Those numbers reveal active disease long before you'd feel it.
How much does gum disease treatment cost in NYC?
Scaling-and-root-planing is billed per quadrant, so the total depends on how many quadrants need treatment — most patients need two to four, depending on how the disease is distributed. Ongoing periodontal maintenance visits and any locally-delivered antibiotic per site are separate when used. You'll leave your evaluation with an itemized written estimate for your specific case, and we'll review what your insurance is likely to contribute along with financing options if you'd like to spread the cost.
Does insurance cover gum disease treatment?
Most PPO plans cover scaling-and-root-planing, often at a meaningful percentage and sometimes subject to your annual deductible. Periodontal maintenance is usually covered too, though on some plans it counts against the same limited number of cleanings per year. Centre Dental is a non-participating (out-of-network) provider with most PPO plans — you pay us directly and we help you submit for out-of-network reimbursement. We'll walk through your specific benefits before treatment so there are no surprises.
Will the treatment hurt?
Scaling-and-root-planing is performed under local anaesthesia, so the treatment itself is comfortable — you'll feel pressure and movement, not pain. Afterward, two to three days of gum soreness and some temporary cold sensitivity are typical, and over-the-counter ibuprofen manages it well for most people. Sensitivity from newly-exposed root surfaces usually settles within a few weeks. If dental anxiety is part of the picture for you, we can discuss comfort and sedation options at your visit.
Can gum disease be cured?
It depends on the stage. Gingivitis — inflammation without bone loss — can be fully reversed with cleaning and good home care. Periodontitis can be controlled and stabilized, but it generally cannot reverse the bone loss that has already happened. The realistic, honest goal is to halt the progression and keep your teeth, and with consistent treatment plus three- or four-month maintenance, most patients do exactly that. Stopping maintenance is the most common reason the disease returns.
How long until I know if the treatment worked?
We re-chart your pocket depths six to eight weeks after scaling-and-root-planing and compare them directly to your baseline numbers. Reduced pockets and fewer bleeding sites tell us the inflammation has resolved; if the numbers haven't improved, we know more treatment is needed rather than guessing. This re-measurement is non-negotiable in our practice — without it, there's no honest way to claim the treatment was effective.
Is gum disease linked to other health conditions?
Yes. Bidirectional associations between periodontitis and cardiovascular disease, diabetes, and adverse pregnancy outcomes are documented in the published literature, though for some of these the causal direction is still being studied. The diabetes link is the best-supported: according to PubMed, a 2022 Cochrane review found periodontal treatment lowered HbA1c by about 0.43% at three to four months in people with diabetes — meaning treating your gums can measurably help your blood-sugar control. Healthy gums genuinely support the rest of your health.
Does smoking affect my gums and my treatment?
Significantly. Smoking is the largest modifiable risk factor for gum disease — according to PubMed, a 2025 genetic analysis estimated it roughly increases the odds of periodontitis (odds ratio about 1.74). It also constricts the small blood vessels in your gums, which masks bleeding, so the disease can advance while looking deceptively calm. Smokers tend to respond less predictably to periodontal therapy, too. We don't lecture — we simply factor it honestly into your plan and your maintenance interval, and we're glad to support you if quitting is on your radar.
The path
Your journey, start to finish
01
Evaluation + full periodontal charting
02
Scaling-and-root-planing
Under local anaesthesia, we remove tartar and bacterial biofilm from below the gum line and plane the root surfaces smooth, usually across two comfortable visits. Locally-delivered antibiotics are placed in specific deep pockets only when the charting shows they're warranted.
03
Re-evaluation at 6–8 weeks
We re-chart the same six points per tooth and compare to your baseline. Reduced pockets and less bleeding confirm the treatment worked; if a site hasn't responded, we address it directly rather than assume — success here is a measured number, not a guess.
04
Periodontal maintenance
Once stable, you move to a three- or four-month maintenance rhythm that keeps the deep sites disrupted before bacteria re-establish. This is the phase that protects your result for the long term — and the one that quietly determines whether the disease stays gone.
When regeneration becomes an option after periodontitis
When advanced gum disease destroys the bone holding teeth in place, scaling alone cannot rebuild what the infection took. Guided tissue regeneration uses a barrier membrane plus graft material (autograft, allograft, or xenograft) placed over the defect to give the body a protected scaffold to regrow bone and periodontal ligament around compromised teeth.
Centre Dental sequences regeneration cases carefully: first stabilizing the active disease with deep cleaning and antimicrobial protocols, then re-evaluating pocket depths after healing before committing to the regenerative surgery. Done at the right moment, the procedure can save teeth that older textbooks would have flagged for extraction.
