Brushing and flossing at home do most of the work of keeping your teeth and gums healthy, but they can’t do everything. Even careful brushers build up plaque in places a toothbrush misses, and over time that plaque hardens into tartar (also called calculus) that no amount of brushing will shift. A professional teeth clean, often called a scale and clean, removes that build-up and gives your dentist a chance to spot problems early, while they’re simpler to treat.
If it’s been a while since your last visit, or you’re not sure what a clean involves, this guide walks through what happens, how long it takes, what it feels like and how often adults should book one.
Why adults need a professional clean
Plaque is a soft, sticky film of bacteria that forms on teeth every day. Left alone for a day or two, it starts to harden into tartar, usually along the gum line and behind the lower front teeth, where saliva glands sit close by. Tartar is rough, so it collects more plaque, and it irritates the gums.
That irritation is the start of gum disease. In its early stage, gingivitis, gums may look red, feel tender or bleed when you brush. Gingivitis is usually reversible with a professional clean and better home care. If it isn’t managed, it can progress to periodontitis, where the tissues and bone that hold teeth in place are slowly damaged. Periodontitis is a common cause of tooth loss in adults, and it often develops without much pain, which is why regular check-ups matter.
A professional clean also removes surface stains from coffee, tea, red wine and smoking, so teeth often look brighter afterwards. It isn’t the same as whitening, though: cleaning removes stains on the surface, while whitening changes the shade of the tooth itself.
What happens during a scale and clean
Every practice works a little differently, but an adult scale and clean at Parramatta Dentistry usually follows these steps.
1. A quick chat and medical history
Your dentist will ask about any changes to your health or medications since your last visit. Some conditions and medicines, such as diabetes, blood thinners or medicines that cause a dry mouth, affect your gums and how they heal, so it’s worth mentioning them even if they seem unrelated.
2. Examination
Before cleaning, your dentist checks your teeth, gums, tongue and the soft tissues of your mouth. They look for decay, worn or broken fillings, signs of grinding and any areas that need a closer look. They may gently measure the small space between your teeth and gums (the gum pocket) to check for gum disease.
3. X-rays, if needed
Small bitewing x-rays show decay between the teeth and changes in the bone that aren’t visible to the eye. A larger OPG x-ray shows the whole jaw, including wisdom teeth. Your dentist will only recommend x-rays when they’re clinically useful, and they’ll explain why.
4. Scaling
Scaling removes tartar from above and just below the gum line. Most practices use an ultrasonic scaler, which vibrates and sprays a fine mist of water to break tartar away, followed by hand instruments to finish the fine detail. You’ll hear a high-pitched hum and feel some vibration and water spray. A suction tube keeps your mouth comfortable.
5. Polishing
After scaling, your teeth are polished with a gritty paste on a soft rotating cup. Polishing smooths the tooth surface so plaque has a harder time sticking, and removes surface stains.
6. Fluoride and advice
Depending on your risk of decay, your dentist may apply fluoride varnish to strengthen enamel. They’ll finish with practical advice for your mouth, such as where you’re missing when brushing, how to floss around crowns or bridges, or whether an interdental brush would suit you better than floss.
How long does a teeth clean take?
A routine check-up and clean usually takes 30 to 60 minutes. If there’s a lot of tartar, or it’s been several years since your last clean, your dentist may suggest splitting the work across two visits so it’s more comfortable and thorough.
Does a scale and clean hurt?
Most people find a clean comfortable. You may feel pressure, vibration and the cool water spray, and some areas can feel sensitive, particularly if your gums are inflamed or you have exposed roots. Tell your dentist if anything is uncomfortable: they can adjust the scaler, use a desensitising gel or offer local anaesthetic for sensitive areas. If you feel anxious about dental visits, let the team know when you book. Gentle care is at the heart of how we work, and we’ll go at your pace.
It’s normal for gums to feel a little tender, or to bleed slightly, for a day or so after a clean, especially if they were inflamed beforehand. This usually settles quickly as your gums heal.
Scale and clean vs deep cleaning
A standard scale and clean treats tartar above and just below the gum line. If your dentist finds deeper pockets and signs of periodontitis, they may recommend a deeper clean, sometimes called root planing or periodontal debridement. This cleans further down the root surfaces, usually with local anaesthetic, and may take more than one appointment. Your dentist will explain what’s involved, the options and the fees before any treatment starts.
How often should adults have a teeth clean?
For many adults, a check-up and clean every six months works well. Some people need cleans more often, for example every three or four months, including people who:
- have a history of gum disease
- have diabetes or are pregnant, as both can affect gum health
- smoke or vape
- build up tartar quickly
- wear braces, clear aligners, implants, bridges or dentures
Others with very low risk may be fine with a longer gap. Your dentist will recommend an interval that suits your mouth rather than a one-size-fits-all rule.
What does a teeth clean cost?
Fees depend on what’s included and what your mouth needs. At Parramatta Dentistry, a new patient visit includes a comprehensive examination, consultation, scale and clean, and x-rays (bitewings and OPG). It’s no gap with an eligible health fund, or $219 without health fund cover. Returning patients can have a check-up and clean for $199 without x-rays, $259 with bitewings or an OPG, or $309 with both. If you need additional treatment, your dentist will explain the options and fees first. Conditions apply, and fees may vary with your clinical needs.
If you have extras cover, check your annual limits. Many funds include two check-ups and cleans a year under preventive dental, and some reset limits on 1 January. You can read more on our health funds and HICAPS page.
Keeping your teeth clean between visits
- Brush twice a day for two minutes with a soft toothbrush and fluoride toothpaste. Angle the bristles towards the gum line.
- Clean between your teeth once a day with floss or interdental brushes. Brushing alone misses about a third of each tooth’s surface.
- Spit, don’t rinse after brushing, so fluoride stays on your teeth longer.
- Limit sugary and acidic drinks, and choose Sydney’s fluoridated tap water instead.
- Replace your toothbrush every three months, or sooner if the bristles splay.
When to book sooner
Don’t wait for your next routine visit if you notice gums that bleed regularly, persistent bad breath, loose teeth, gums pulling back from your teeth, a bad taste or tooth sensitivity that doesn’t settle. These can be signs of gum disease or decay, and both are easier to manage when they’re found early.

Frequently asked questions
Can I eat straight after a scale and clean?
Yes, in most cases you can eat and drink straight away. If you’ve had fluoride varnish applied, your dentist may suggest avoiding hot drinks and hard or sticky foods, and not brushing, for a few hours so the fluoride stays on your teeth. If you had local anaesthetic, wait until the numbness wears off before eating so you don’t bite your cheek or tongue.
Will a clean make my teeth whiter?
A clean removes surface stains and tartar, so teeth often look brighter and feel smoother. It doesn’t change the natural shade of your teeth. If you’d like them lighter than their natural colour, talk to your dentist about professional whitening after your clean.
Why do my gums bleed during a clean?
Bleeding during a clean usually means the gums are inflamed, most often from plaque and tartar sitting along the gum line. Once the build-up is removed and you keep up good cleaning at home, the gums usually settle and bleed less within a week or two. Gums that keep bleeding should be checked for gum disease.
Is it bad if I haven’t had a clean in years?
It’s very common, and there’s no judgement. Your dentist will assess your teeth and gums and may suggest spreading the cleaning over more than one visit if there’s a lot of tartar. Starting now is the most important step.
Do electric toothbrushes clean better?
Both manual and electric toothbrushes can clean well when used properly. Many people find powered brushes with a two-minute timer and pressure sensor make it easier to brush thoroughly and gently. Your dentist can tell you whether your current brushing is reaching all areas.
