Regular Dental Cleaning vs. Deep Cleaning: What's the Difference?

A regular cleaning(prophylaxis) takes care of plaque and tartar above the gum line. Deep cleaning (scaling and root planing) is a different thing entirely, going below the gum line into areas a standard cleaning was never designed to reach.

For healthy gums, coming in every six months is usually all it takes. Gum disease changes that to every three to four months. The cutoff between the two procedures comes down to one measurement your hygienist takes at every visit: 4 mm of pocket depth.

What Is a Regular Dental Cleaning?

Your registered dental hygienist handles this one. One appointment and it is done.

The procedure consists of three steps:

1. Scaling breaking down hardened buildup using hand tools or an ultrasonic device.
2. Then polishing, which smooths surface stains.
3. Another is fluoride or sealants if necessary— usually those with a higher cavity risk.

Start to finish, expect 30 to 60 minutes and done with a single visit. Most adults do this every six month.

Regular cleaning, however, isn't for everyone. Patients with periodontitis — where infection has gone deeper and started affecting bone — need more than a standard routine cleaning can offer. That's where periodontal maintenance cleaning comes in.

And if the probe finds deeper pockets or tartar below the gum line — a prophylaxis isn't enough. Deep cleaning is what you needed.

What Is a Deep Cleaning? (Scaling and Root Planing)

Scaling and root planning is a non-surgical gum disease treatment. It reaches areas a routine cleaning never touches.

There are two parts to it. First, scaling — that's where the hygienist clears out plaque and tartar, not just above the gum line but below it too, even the stuff that's built up on the roots. Then root planing, which smooths the root surfaces down so the gum tissue actually has a chance to heal and reattach the way it should.

Going below the gum line means local anesthesia is standard. One quadrant gets numbed at a time, with two appointments typical — one half of the mouth per visit, 60 to 90 minutes each.

Modern deep cleaning in Culver City goes beyond hand tools. Most offices use an ultrasonic scaler — a Cavitron — to break apart tartar more comfortably. Deeper pockets may also get Arestin, small antibiotic microspheres that keep fighting bacteria after you leave. Some cases call for laser-assisted periodontal therapy too.

Why not numb everything at once? It gets uncomfortable quickly — and risks exceeding safe lidocaine limits.

After scaling and root planing, a periodontal maintenance schedule usually follows. Here’s everything you need to know about periodontal maintenance if you want the full picture.

How does your dentist decide you need this over a routine cleaning? It comes down to one number — and a probe.

How We At United Dental Care Decide Which Cleaning You Need

Before anything else gets touched, our hygienist measures first. A periodontal probe goes around every tooth — six points each, hitting both the buccal side facing your cheek and the lingual side facing your tongue. All those numbers together make up your perio chart.

Here's what they mean. Pockets at 1 to 3 mm are healthy territory — routine cleanings handle that range. At 4 mm, bacteria start settling deeper and deep cleaning is often recommended. Hit 5 mm with bleeding on probing and periodontitis is usually confirmed. At 6 mm or beyond, the disease is more advanced — Arestin or a periodontist referral may enter the conversation.

Healthy gums don't bleed when probed. If yours do, that's inflammation — not sensitivity.

Ask to see your perio chart. A trustworthy office shows you the numbers, points out the deeper pockets, and tracks changes over time. "You need a deep cleaning" without explanation isn't enough.

The clinical line is firm too. Performing a routine cleaning on a patient with diagnosed periodontitis isn't just ineffective — polishing overactive disease can accelerate bone loss.

Dr. Abbas Eftekhari, D.D.S. and our Culver City United dental care team review every perio chart before recommending scaling and root planing.

So how do the two actually compare? Here's the breakdown.

Quick Comparison: Prophy vs. SRP vs. Periodontal Maintenance

Three procedures come up most often when patients ask about cleanings — a regular cleaning, or prophy, a deep cleaning which is scaling and root planing, and periodontal maintenance for anyone who's already gone through gum disease treatment. How long you're in the chair, what your insurance actually pays for, how the visit feels, and how often you need to come back — all of that shifts depending on which one you need.

Attribute	Regular Cleaning (Prophy)	Deep Cleaning (SRP)	Periodontal Maintenance
ADA Code	D1110	D4341 / D4342	D4910
Who it's for	Healthy gums, mild plaque	Diagnosed gum disease, pockets 4 mm+	After SRP, to keep disease controlled
Where it cleans	Above the gum line	Above + below the gum line, on root surfaces	Above + below, plus pocket monitoring
Anesthesia	None typically	Local anesthesia, often by quadrant	Usually none, occasionally local
Time	30–60 minutes, 1 visit	60–90 minutes, often split into 2 visits	45–60 minutes per visit
Frequency	Every 6 months	One-time treatment per affected area	Every 3–4 months (lifelong)
Typical LA-area cost*	~$95–$200	~$150–$350 per quadrant	~$150–$250
Insurance (PPO typical)*	Usually 100% covered	Often 80% (major service)	Often 80%, may share annual cleaning cap

*Cost ranges reflect typical fees in Los Angeles County for 2026. Your actual cost depends on your insurance plan and the number of quadrants treated.

Cost is one of the first questions every patient asks. Here's the cost of cleaning procedure in Culver City.

How Much Does a Deep Cleaning Cost in Culver City?

Regular cleanings around LA — $95 to $200. Varies by office but that's the typical range. Deep cleaning — different story. Billed by quadrant, $150 to $350 each. Treating the full mouth adds that up to roughly $600 to $1,400 before insurance touches it.

That difference surprises people. But the procedures aren't comparable in scope. One visit versus multiple. No anesthesia versus local. Above the gum line versus below it.

Insurance treats them differently too. Most PPO plans cover routine cleanings at or near 100%. Scaling and root planing typically comes in at 80% after your deductible.

One detail patient often miss — many plans cap at two visits per year. On a three-month periodontal maintenance schedule, visits three and four may come out of pocket.

In Culver City, being in-network with most major PPO plans matters. Our front desk verifies your dental benefits before any periodontal procedure, so the estimate you see is the estimate you pay.

Cost is one consideration. The bigger question is — what happens if you skip the deep cleaning altogether?

What Happens If You Don't Get a Deep Cleaning?

Periodontitis doesn't announce itself. It moves slowly, rarely causes pain early on, and by the time most patients notice something is wrong — a loose tooth, receding gums — damage has already been done.

The process is gradual. Bacteria settle. Inflammation follows. Bone breaks down — slowly, over years, without obvious warning signs. By the time teeth start loosening the damage is already well established. Dentists call that bone resorption.

And it doesn't stay in your mouth. Gum disease is tied to diabetes, heart disease, preterm birth, low birth weight. That is why protecting your teeth during pregnancy matters more than most realize.

Periodontitis is managed; it isn't something you cure. A deep cleaning stops dental disease from being active. Periodontal maintenance is what keeps it from coming back once the deep cleaning is done.

Frequently Asked Questions

Q1. Is a deep cleaning painful?

With local anesthesia, the procedure itself isn't something most patients find painful — pressure is the more common description. Some gum tenderness for a couple of days after is normal and easy to manage.

Q2. Why is a deep cleaning split into two visits?

Two quadrants get treated per visit — one half of the mouth at a time. It keeps appointments shorter, lets you leave with feeling on one side, and gives treated areas time to start healing.

Q3. Can I just get a regular cleaning instead?

Not if periodontitis is already in the picture. Regular cleanings don't go below the gum line. The infection does. Polishing overactive disease can actually accelerate bone loss — so no, it's not a workaround.

Q4. How much does a deep cleaning cost in Culver City?

Per quadrant, $150 to $350 around LA. Full mouth puts you somewhere between $600 and $1,400 out of pocket. PPO plans usually pick up around 80% after deductible.

Q5. How long until my gums feel normal again?

A week for most people. Day two or three tends to be the peak — after that, sensitivity fades. Sensodyne and warm saltwater rinses make a difference. Your dentist re-checks pocket depths at four to six weeks.
