December 2, 2025

A professional teeth cleaning is one of the simplest, most important things you can do for your oral health. But what really happens during the appointment? Many patients don’t know. This article will explain what happens during a dental cleaning so you know what to expect. Some wonder if it’s painful. Others think it’s unnecessary if they brush and floss regularly. And some avoid it altogether because of anxiety or uncertainty.

The truth is simple: professional cleanings do what brushing and flossing at home can’t do. A typical dental cleaning involves removing plaque and tartar, polishing your teeth, and checking for signs of gum disease or other oral health issues. They prevent gum disease, remove plaque, protect the teeth from decay and allow your dentist to detect problems early — before they become emergencies.

As a trusted dentist in Astoria, MediDental Care does hundreds of cleanings a month and patients are always surprised how thorough and comfortable the process is. In this guide we’ll break down exactly what happens during a professional cleaning, step by step — from the moment you sit in the chair to the final fluoride treatment.

Why Professional Teeth Cleanings Matter

Even the best brushing and flossing can’t remove all plaque, reach every area of the mouth or eliminate tartar (hardened plaque). Once tartar forms only a professional can remove it safely. Regular cleanings are essential for good oral health and dental health, as they help prevent the buildup of plaque and tartar that can lead to serious issues.

Professional cleanings:

  • Prevent cavities
  • Reduce the risk of gum disease
  • Remove bacteria and tartar
  • Freshen breath
  • Brighten the smile
  • Protect against infection
  • Help detect problems early
  • Prevent dental problems and tooth loss

Regular cleanings are crucial for maintaining good oral health and preventing dental problems that could lead to tooth loss.

Skipping cleanings increases the risk of pain, swelling, bleeding gums and infections — the kind that may require an emergency dentist in Astoria later.

Step 1: Medical & Dental History

Every cleaning starts with a quick review of your medical history and dental history. Your provider may ask:

  • Any new meds?
  • Any recent health changes?
  • Any dental pain or sensitivity?
  • Any bleeding while brushing or flossing?

This step ensures the cleaning is safe and tailored to your needs.

Because MediDental Care offers integrated medical and dental services, this evaluation is more thorough than most traditional offices, giving patients a full picture of their oral and overall health.

Step 2: Digital X-Rays (If Needed)

X-rays are not done at every visit but are essential to spot issues you can’t see with the naked eye:* Cavities between teeth

  • Bone loss
  • Infections or abscesses
  • Impacted teeth
  • Problems under fillings or crowns

Your dentist in Astoria will decide if X-rays are needed based on your history and symptoms.

Step 3: Oral Exam

Before the cleaning begins, your dental professional will use a small mirror to examine your teeth and gums to check:

  • The health of both teeth and gums
  • Plaque buildup
  • Signs of inflammation
  • Condition of old fillings or crowns
  • Early signs of infection
  • Tooth wear or grinding
  • Signs of oral cancer

This exam helps catch problems early before they become costly procedures.

If anything concerning is found — swelling, abscess formation, bleeding gums or signs of infection — you may be referred to an emergency dentist in Astoria for immediate care.

Step 4: Scaling — Removing Plaque & Tartar

Scaling is the most important part of the cleaning. The goal is to remove plaque and tartar, including harmful plaque that can cause cavities and gum disease. This is where your hygienist removes plaque and tartar from the teeth and gumline using specialized tools.

What is plaque?

A sticky film of bacteria that forms daily on your teeth.

What is tartar?

Hardened plaque that cannot be removed at home.

How scaling works

Your hygienist uses:

  1. Ultrasonic scaler – vibrates to gently break apart tartar
  2. Hand scalers – fine tools for detailed cleaning

Scaling removes bacteria that cause:

  • Cavities
  • Gum disease
  • Bad breath
  • Infections

Patients often say scaling feels “scratchy” but not painful. If your gums are sensitive a topical numbing gel can be applied.

Step 5: Deep Cleaning (If Needed)

If you have gum inflammation or tartar buildup beneath the gums your dentist may recommend a deep cleaning, also known as scaling and root planing.

If signs of gum disease or periodontal disease are found during your evaluation, periodontal therapy may be recommended as part of your treatment plan.

Deep cleaning is an important step in achieving and maintaining optimal oral health.

Deep cleaning is needed if you have:

  • Bleeding gums
  • Gum pockets deeper than 4mm
  • Signs of early gum disease
  • Persistent bad breath
  • Swelling around the gums

Deep cleaning removes bacteria beneath the gums and smooths the roots to prevent future buildup.

Ignoring these signs can lead to gum infections — the kind that may require an emergency dentist in Astoria if they worsen.

Step 6: Polishing — Smoothing & Brightening the Teeth. After scaling the hygienist will use a polishing tool with a special paste to:

  • Smooth the enamel
  • Remove surface stains
  • Make it harder for plaque to stick
  • Leave teeth looking brighter and cleaner

After scaling, the hygienist will use a high-powered electric brush along with a gritty toothpaste known as prophylaxis paste for tooth polishing. This process effectively removes leftover plaque, smooths the enamel, and gives your teeth a polished, shiny finish.

This is painless and leaves a smooth, fresh feeling.

Step 7: Flossing

Even if you floss daily (and many don’t) professional flossing helps remove debris and polish the spaces between teeth.

The hygienist will:

  • Floss between each tooth
  • Remove any leftover buildup and any remaining debris
  • Identify areas you may be missing at home
  • Check for bleeding or sensitivity

If significant bleeding occurs it may be a sign of early gum disease or inflammation.

Step 8: Fluoride

Fluoride is the final step in most cleanings. It strengthens enamel and protects teeth from decay for several months.

9.1. Fluoride can be applied in several forms:

  • Gel
  • Foam
  • Varnish
  • Liquid fluoride

If you’re prone to emergency dental issues fluoride adds an extra layer of protection. This extra protection helps prevent cavities by strengthening enamel and making teeth more resistant to acid attacks.

Fluoride may be applied as:

  • Gel
  • Foam
  • Varnish

Varnish is the most common — it hardens quickly and you can eat immediately after your appointment.

Fluoride is especially important for patients who have:

  • Frequent cavities
  • Sensitive teeth
  • Acidic diets
  • Dry mouth
  • Old or worn restorations

If you’re prone to emergency dental issues fluoride adds an extra layer of protection.

Step 9: Examination & Treatment

Once the cleaning is complete, the dentist will perform a final examination to ensure:

  • No infections are present
  • No cavities need treatment
  • Gum health is stable
  • Teeth are properly aligned
  • You understand at-home care

During this final examination, the dentist will also address any specific concerns you may have.

You may also be advised to return sooner than six months if you have gum inflammation, medical conditions or rapid tartar buildup.

How long does a cleaning take?

Most cleanings take 30–60 minutes depending on:

  • Amount of tartar
  • Gum health
  • X-rays needed
  • Deep cleaning required

Patients with gum disease may require multiple visits.

Does it hurt?

For most people no. You may feel:

  • Mild pressure
  • Slight sensitivity
  • Cold or scraping sounds

If you have sensitive gums or a lot of tartar numbing gel can make the process painless.

Signs you need a cleaning nowWaiting too long between cleanings can lead to infections or gum disease. You should schedule a visit with a Astoria dentist if you notice:

  • Bleeding during brushing
  • Bad breath
  • Tartar buildup
  • Sensitivity
  • Puffy or red gums
  • Pain when chewing
  • Loose teeth
  • Receding gums

If you notice any of these symptoms, it's important to schedule regular dental cleanings, as they play a crucial role in preventing gum disease and maintaining your oral health. If these symptoms become severe — swelling, fever, or intense pain — you may need an emergency dentist in Astoria.

What If You Miss Your Cleaning?

Delaying cleanings increases your risk for:

  • Gum disease
  • Tooth infections
  • Bone loss
  • Cavities under the gumline
  • Pain and swelling
  • Costly dental procedures

It is important to visit a dental office for regular cleanings, as professional care helps prevent these issues and maintains your oral health.

Many dental emergencies we treat at MediDental Care start as small issues that were left untreated. Unlike many dental offices, MediDental Care is committed to thorough checkups and comprehensive care to help you avoid future problems.

Professional Cleaning vs. At-Home Brushing

Brushing and flossing at home are important, but they can’t:

  • Remove tartar
  • Clean below the gumline
  • Detect early infection
  • Reverse gum disease
  • Remove deep staining
  • Identify oral cancer signs

A professional dental cleaning, performed by a dental professional, thoroughly removes plaque and tartar, polishes your teeth, and often includes a fluoride treatment. When combined with good oral hygiene practices at home, such as regular brushing and flossing, this helps maintain good oral health and prevents issues like gum disease and cavities.

A dental cleaning is not a luxury — it’s preventive healthcare.
