If you’ve been told you need a “deep clean,” you might be thinking one of two things.

“Isn’t that just a longer version of my normal clean?”

Or: “That sounds like it’s going to hurt.”

Neither is quite right. A deep clean is a different treatment with a different purpose, and for most people it’s far more manageable than they expect. Here’s what really happens.

Why a normal clean isn’t enough

A regular scale and clean removes plaque and tartar from the visible parts of your teeth and just around the gumline. That’s ideal for healthy gums.

But when gum disease (periodontitis) sets in, the gums start to pull away from the teeth and form pockets. Inside those pockets, bacteria and hardened tartar build up on the root surfaces, below the gumline, out of reach of your toothbrush, your floss, and a standard clean.

Think of it like a splinter under the skin. Cleaning the surface won’t help while the cause is still sitting underneath.

Scaling and root planing goes into those pockets to:

• Scale: remove plaque and tartar from the tooth and root surfaces below the gumline

• Root plane: smooth the root surfaces so bacteria find it harder to stick and the gums have a better chance to heal and tighten

How do we know you need it?

We measure your gum pockets with a small, gentle probe marked in millimetres. We take several measurements around each tooth.

As a general guide:

• 1–3 mm is usually considered healthy

• 4 mm or more can indicate gum disease, especially if the area bleeds

We’ll also look at X-rays to check bone levels around your teeth. These measurements become your “before” picture, so we can compare them later.

What happens at the appointments

How many visits?

It depends on how much of your mouth needs treatment. Your mouth is divided into four sections called quadrants. Some people need one or two quadrants treated; others need all four. Treatment is commonly done over one to several appointments, and we’ll set out your schedule in your treatment plan.

Step 1: Getting comfortable

Because we’re working below the gumline, we usually numb the area with local anaesthetic. For most people, this is the part that makes the biggest difference to comfort.

If you’re nervous, tell us before we begin. We can go slower, agree on a stop signal, and talk about sedation options where appropriate. (See: Does gum treatment hurt? Pain, sedation, anxiety and recovery time.)

Step 2: The cleaning

We use a combination of:

• Ultrasonic instruments, which vibrate and use a water spray to break up tartar

• Fine hand instruments, which clean and smooth the root surfaces

You’ll feel pressure, vibration and some scraping sensations, and you’ll hear the instruments. With the area numbed, you shouldn’t feel sharp pain. If you do, let us know straight away.

Step 3: Finishing up

We rinse the area and may, in some cases, apply a medicated treatment into deeper pockets. We’ll then go through your aftercare instructions.

Length: this depends on how many areas are being treated. We’ll tell you how long to allow before each visit.

How it feels afterwards

Everyone is a little different, but here’s what people commonly notice.

The first few hours: numbness wears off. Avoid hot drinks and chewing until it does, so you don’t bite your cheek or tongue.

The first few days:

• Gums may feel tender or a little sore

• Some light bleeding when brushing is common at first

• Teeth may be more sensitive to hot and cold

The first few weeks:

• Sensitivity usually settles gradually

• As swelling goes down, your gums may tighten, and some people notice their teeth look slightly longer or small gaps appear between them. That’s the inflammation settling, not new damage.

Simple ways to stay comfortable:

• Over-the-counter pain relief if needed (follow the label, and check with your pharmacist if you take other medicines)

• Warm salt-water rinses, if we recommend them

• Soft foods for a day or two

• A soft toothbrush and a toothpaste for sensitive teeth

• Keep brushing and cleaning between your teeth gently, even if the gums bleed a little at first. Stopping lets plaque build up again.

Call us if you notice: swelling that gets worse after a few days, fever, severe pain, or bleeding that won’t stop.

How we know if it has worked

This is the part people don’t expect: the deep clean itself is only half the treatment. The other half is healing time and a re-check.

A few weeks after treatment (commonly around 6 to 12 weeks), we’ll measure your gum pockets again and compare them to your first measurements.

What we’re hoping to see:

• Less bleeding

• Shallower pockets

• Healthier-looking gums

What happens next depends on the results:

• If the gums have responded well, you’ll move to a regular maintenance schedule.

• If some deeper pockets remain, we may recommend further treatment for those specific areas, which can include gum surgery.

We can’t promise every area will respond the same way. How well gums heal depends on how advanced the disease was, your home care, and factors such as smoking and diabetes.

Your part in the result

A deep clean resets the starting line. What happens next is a partnership.

Daily home care. Brushing twice a day and cleaning between your teeth once a day with floss or interdental brushes. We’ll show you which tools suit your mouth.

Not smoking. Smoking is one of the biggest risk factors for gum disease and poor healing. If you’d like help quitting, your GP or Quitline (13 7848) can help.

Managing other health conditions. If you have diabetes, keeping it well controlled supports gum health.

Regular maintenance visits. Gum disease can return. Regular reviews help catch it early, and we’ll recommend a maintenance schedule based on how your gums respond.

What does it cost?

The cost depends on how many areas need treatment, the severity of the condition and the appointments required. Prime Perio provides a written, itemised quote after assessment.
