Deep Cleanings and Gum Care

When a routine cleaning isn't enough, this deeper treatment reverses early gum disease and restores healthy gums, at our Fremont, Cupertino, and Milpitas offices.

Gum disease is more common than you'd expect

According to the CDC, roughly 47% of US adults aged 30 and older have some form of periodontal, or gum, disease. That number climbs above 70% for adults 65 and older. Most don't know it, because the early stages are painless and silent.

Untreated gum disease is the leading cause of tooth loss in adults. It's also been linked by the NIH to cardiovascular disease, diabetes complications, and adverse pregnancy outcomes. The good news is that at every early stage, it's treatable, and often fully reversible.

A deep cleaning, clinically called scaling and root planing, is the most common first-line treatment when routine cleanings can no longer keep things under control. For patients across Fremont, Cupertino, and Milpitas, it's one of the most consistently effective procedures we offer.

Routine cleaning versus deep cleaning

These two procedures sound similar but address different problems. A routine cleaning maintains already healthy gums. A deep cleaning treats gums that are no longer healthy.

Who it's for: a routine cleaning suits healthy gums with no bone loss; a deep cleaning addresses gum inflammation, pockets deeper than 4mm, or early bone loss.
What's cleaned: a routine cleaning reaches above and just below the gumline; a deep cleaning goes further, into the pockets down to the tooth root.
Visits required: a routine cleaning is usually one visit; a deep cleaning is usually two, treating half the mouth at a time.
Anesthesia: a routine cleaning doesn't need it; a deep cleaning uses local numbing for comfort.
Frequency: routine cleanings are typically every six months; after a deep cleaning, maintenance visits move to every three to four months.

How gum disease progresses

Gum disease moves in stages, and the earlier we catch it, the easier it is to reverse. We measure progression by gently checking the space between your tooth and gum with a small probe. The deeper the pocket, the further along the disease.

Gingivitis: inflammation only. Gums are red, swollen, and bleed when brushing, with no bone loss yet. Fully reversible with improved hygiene and routine cleanings.
Early periodontitis: pockets forming. Gum pockets deepen to 4 or 5mm and mild bone loss begins. Deep cleaning is most effective here, while we can still fully halt progression.
Moderate periodontitis: bone loss accelerates. Pockets reach 5 to 6mm with visible gum recession. Deep cleaning is essential, sometimes paired with localized antibiotics.
Advanced periodontitis: tooth mobility risk. Pockets exceed 6mm with significant bone loss, and a surgical referral may be needed. Deep cleanings remain part of ongoing maintenance.

A deep cleaning isn't a punishment for skipped visits. It's the right tool for a specific problem, used when it's genuinely needed, not as an upsell.

What a deep cleaning actually involves

A deep cleaning is typically done over two visits, treating half your mouth each time, so you're never numb on both sides at once and can eat normally between appointments. Each visit takes about an hour. Your doctor numbs the area first, then uses ultrasonic and hand instruments to remove tartar and bacteria from deep inside the gum pockets and along the tooth root.

Sometimes paired with

Local antibiotics, applied directly into deep pockets for stubborn infection.
Prescription mouthwash, to support healing in the weeks after.
Bite adjustment, if grinding is worsening gum recession.
Night guard, for patients whose grinding contributes to gum stress.

Measure pocket depths. Your doctor measures every gum pocket with a small probe. This is the baseline we compare to after treatment.
Numb the area. Topical gel first, then local anesthetic for the half of your mouth being treated. Comfort isn't optional.
Scaling. Tartar and bacterial buildup are removed from above and below the gumline using ultrasonic and hand instruments.
Root planing. Tooth roots are smoothed where bacteria have roughened them, making it harder for new tartar to attach. This is the step a routine cleaning can't replicate.

What to expect during healing

Gums need a few days to two weeks to fully heal. Most patients feel back to normal within 48 hours. Here's what's typical, and what's worth a call.

Normal and expected

Mild soreness for 24 to 48 hours. Over-the-counter pain relievers are usually plenty.
Sensitivity to hot, cold, or sweet. Often improves within one to two weeks as gums tighten.
Light bleeding when brushing. Should improve daily, not worsen.
Gums may look more receded. Healthy gums often look slightly more receded once swelling goes down. That's a good sign.

Worth calling about

Severe pain not helped by over-the-counter medication, especially if it's worsening.
Heavy bleeding that doesn't slow down after 24 hours.
Swelling that increases after the first day or two.
Fever, drainage, or a persistent bad taste can signal infection.

Periodontal maintenance: your new normal

Once you've had a deep cleaning, your gums need closer monitoring than before. Standard six-month cleanings aren't enough, since the bacteria that caused the problem grow back in roughly three months, and we need to remove them before they re-establish.

That's why we move patients to a maintenance schedule every three to four months after a deep cleaning. The visits feel similar to a routine cleaning, but we re-measure pocket depths each time and watch for any early signs of recurrence. We check your plan before scheduling maintenance visits, so you know what to expect.

With consistent maintenance, most patients can stop or slightly reverse early periodontitis, keeping their natural teeth for life.

Common questions

Gum disease and deep cleaning, answered

How do I know if I need a deep cleaning?

The most common signs are bleeding gums, gum recession, persistent bad breath, or visibly inflamed tissue. We measure your gum pocket depths at every routine visit, and if any reach 4mm or deeper, that's typically when we recommend a deep cleaning. We never recommend one without showing you the measurements first.

Does a deep cleaning hurt?

Not during the procedure. You'll be fully numbed before any work begins. Afterward, you may have mild soreness for a day or two, but most patients describe it as similar to a routine cleaning. Over-the-counter pain relievers are usually all you need.

Why does it take two visits?

Doing one half of your mouth per visit means you're never numb on both sides at once, and you can eat and drink normally between appointments. It also lets your doctor work more thoroughly and gives tissue time to begin healing.

Does insurance cover deep cleanings?

Deep cleanings are usually billed as periodontal therapy, and coverage varies by plan. We measure and document your pocket depths, then check your plan and tell you exactly what to expect before scheduling.

Can gum disease affect my overall health?

Yes, the connection is well documented. The NIH and CDC both link untreated periodontal disease to increased risk of heart disease, complications managing diabetes, and adverse pregnancy outcomes including preterm birth and low birth weight. Treating gum disease has measurable effects on these systemic risks.

Will my gums look different afterward?

A little, and that's a good sign. Once inflammation goes down, healthy gums often look slightly more receded than the swollen gums you had before. Teeth may feel more sensitive at first because more root is exposed. Both effects fade within a few weeks.
