A routine dental cleaning (often called a “scale and polish”) is a professional tidy-up for your teeth. Using specialist instruments, your dentist or hygienist removes soft plaque and hardened tartar that brushing and flossing can’t shift, then polishes the teeth to make them smoother and easier to keep clean. It’s a simple, preventive visit that helps stop gum disease and tooth decay, keeps breath fresher, and supports long‑term oral health.

In this guide, you’ll learn exactly what happens during a cleaning, how long it typically takes, and who carries it out. We’ll explain how often you should book in, how a routine clean differs from a deep clean, and the benefits you can expect — plus any temporary side effects. You’ll also find what’s usually included (like X‑rays and exams), practical aftercare tips to keep teeth clean between visits, typical UK costs, comfort options for nervous patients, and how to prepare.

What happens during a routine dental cleaning (step-by-step)

Think of a routine dental cleaning as a reset for your mouth. It targets the plaque and tartar a toothbrush can’t reach, smooths the tooth surface, and leaves you with a cleaner canvas that’s easier to maintain at home. Here’s the step-by-step you can expect.

Initial check: Your dentist or hygienist inspects your teeth and gums, looking for signs of decay, bleeding, or gum inflammation. They’ll flag anything that needs treatment and explain the plan for your scale and polish.
Plaque and tartar removal (scaling): Using hand scalers and/or an ultrasonic tip that vibrates and sprays water, they lift away deposits above the gumline. Scraping sounds are normal; it shouldn’t hurt. Heavy build-up may need more time or a separate debridement visit.
Rinse and re-check: You’ll rinse to clear debris, and they’ll verify all deposits are gone.
Polishing: A soft rubber cup and fine paste (or air polishing) remove surface staining and biofilm, leaving teeth smoother and shinier.
Interdental clean: Many clinicians finish with expert flossing or interdental brushes and show you the best technique for your gaps.
Preventive boost (as needed): Fluoride varnish may be applied to strengthen enamel. Sealants can be discussed for deep grooves in back teeth. Routine X‑rays are taken separately if you’re due.

You’ll leave with tailored aftercare so you can keep that “just-cleaned” feel for longer.

Who performs a routine cleaning: dentist, hygienist or therapist

Routine dental cleaning (a scale and polish) is most often carried out by a dental hygienist, who focuses on removing plaque/tartar and coaching you on home care. Dental therapists can also provide routine cleanings and some restorative treatments under a dentist’s prescription. Your dentist may do the clean during a check‑up, especially at your first visit. If gum disease or decay is spotted, you’ll be scheduled with the appropriate clinician for further care.

How long does a cleaning take (and what can affect it)

Most routine dental cleaning appointments take around 30–60 minutes. If you’re due X‑rays, have heavier tartar build‑up, or it’s your first visit, allow a little longer. Deep cleaning (scaling and root planing) or a gross debridement for heavy deposits can take additional time or be staged over separate visits.

Build‑up and time since last visit: More plaque/tartar usually means more time.
Gum health: Inflammation or bleeding requires slower, careful scaling.
Sensitivity and comfort measures: Numbing gel or local anaesthetic adds setup time.
Braces or complex restorations: Brackets, bridges and crowns need meticulous cleaning.
Extras on the day: X‑rays, fluoride varnish and tailored home‑care coaching extend the visit.

For most people, a routine clean (scale and polish) is comfortably under an hour.

How often should you have a dental cleaning

How often you should have a routine dental cleaning depends on your oral health and risk. For many people, a six‑monthly clean (once or twice a year) works well, but your dentist or hygienist will recommend a personalised interval after examining your teeth and gums. Guidance supports risk‑based recalls: if your mouth stays healthy between visits, you may not need to come as often; if issues are found, you’ll be asked back sooner.

You may need more frequent cleans if you have:

Gum disease (periodontitis) or gingivitis: closer monitoring and maintenance.
Heavy plaque/tartar or a long gap since your last visit: extra build‑up needs tighter recall.
Family history of plaque build‑up or cavities: higher decay risk.
A weakened immune system: reduced ability to fight oral infections.
Illness or significant stress: these can trigger changes in your mouth.

If you’re unsure, book a check‑up and your clinician will set the right schedule for you.

Routine clean vs deep clean: what’s the difference?

If your gums are healthy, a routine dental cleaning (scale and polish/prophylaxis) focuses on removing plaque and tartar from the visible tooth surfaces and then polishing. If you have signs of gum disease (periodontitis) with deeper pockets, your clinician may recommend a deep cleaning — scaling and root planing — to flush bacteria and hardened calculus from below the gumline around the roots, usually with local anaesthetic.

Purpose: Routine clean = prevention and maintenance; deep clean = active treatment for gum disease.
Where it cleans: Routine = above the gumline; deep clean = below the gumline on root surfaces.
Comfort needs: Routine = rarely needs anaesthetic; deep clean = typically done with local anaesthetic.
Time/visits: Routine = about 30–60 minutes; deep clean = longer and often split over multiple visits.
Next steps: Routine = standard recall; deep clean = periodontal review and maintenance. Heavy build‑up may first need a gross debridement before either.

Benefits of regular cleanings

A routine dental cleaning does more than make your teeth feel smooth. By removing plaque and tartar that home care misses and reinforcing your technique, it lowers day‑to‑day risks and makes your mouth easier to maintain. Many people also notice fresher breath and a subtly brighter smile after a professional scale and polish.

Disease prevention: Lowers your risk of cavities and gum disease.
Fresher breath: Reduces odour‑causing bacteria and trapped debris.
Brighter appearance: Polishing lifts surface stains and smooths enamel.
Early detection: Regular reviews catch issues sooner, when simpler to treat.
Lower long‑term costs: Prevention helps avoid more complex, expensive work.
General health links: Better oral health is associated with improved overall health and periodontal treatment outcomes.

Risks, side effects and when to seek advice

A routine dental cleaning is safe and effective, with no known complications for most people. The most common side effects are short‑lived — temporary tooth sensitivity and tender gums — and they usually settle within a few days. If you’re uncomfortable, an over‑the‑counter pain reliever can help.

Common, short‑term effects: brief sensitivity to cold or pressure; mild gum tenderness after your scale and polish.
What to expect: any tenderness should ease within a few days.

Seek advice if:

Discomfort is severe or not improving after a few days.
You develop new symptoms, such as a toothache, bleeding gums or loose teeth.
You’re unsure whether you need a routine dental cleaning or further periodontal treatment — your clinician can advise on next steps.

X-rays, exams and what’s usually included

A routine dental cleaning usually comes with a brief clinical check and targeted preventive care. Your clinician will examine your mouth first, then carry out a scale and polish. Dental X‑rays are not taken at every visit; they’re done when you’re due, typically every 6–36 months depending on your risk and history. If anything needs attention, you’ll leave with clear recommendations.

Clinical exam: Teeth, gums and a quick head/neck and soft‑tissue check to spot problems early.
Scaling: Removal of plaque and tartar above the gumline using hand or ultrasonic instruments.
Polishing: Rubber‑cup paste or air‑polishing to lift surface stains and smooth enamel.
Interdental clean: Expert flossing/brushes and technique coaching.
X‑rays (when due): Taken at intervals based on your risk (often 6–36 months).
Preventive extras (as needed): Fluoride varnish; discussion of sealants for deep grooves.
Advice & plan: Personalised home‑care tips, recall interval, and referrals/treatment plan if required.

Aftercare: how to keep your teeth clean between visits

Good home care keeps the results of your routine dental cleaning going for months. Focus on daily plaque control, fluoride protection and gentle technique. That combination makes future scale and polish visits quicker, keeps gums healthy and helps prevent decay and bad breath.

Brush twice daily for 2 minutes: last thing at night and on one other occasion.
Use fluoride toothpaste: choose at least 1,350 ppm fluoride for adults.
Don’t rinse after brushing: spit out excess; use a fluoride mouthwash at a different time, and avoid food/drink for 30 minutes after mouthwash.
Clean between teeth every day: floss or use snug‑fitting interdental brushes (or a water flosser) before brushing; avoid wooden toothpicks.
Be gentle: small circular motions along the gumline; also brush your tongue to reduce odour‑causing bacteria.
Smart habits: cut down on sugary snacks/drinks; if you’ve had fluoride varnish, wait 30 minutes before eating; if you smoke, ask your clinician for help to quit.

Cost of routine dental cleaning in the UK

The cost of a routine dental cleaning in the UK varies because it depends on the setting (NHS or private), the time needed and any extras included on the day. Private hygiene fees are set by each practice and reflect the length and complexity of your scale and polish. X‑rays and fluoride varnish are only added if you need them and may be charged separately. At Wigmore Smiles, we’ll give you a clear estimate before treatment and offer 0% finance on eligible plans.

What influences price:

Appointment length and build‑up: heavier tartar needs longer cleaning.
Extras on the day: X‑rays (taken when due) and fluoride treatments.
Type of clean: routine scale and polish vs periodontal therapy.
First visit vs maintenance: initial debridement can be separate.
Location and clinician: local pricing and whether you see a hygienist, therapist or dentist.

If you’re comparing options, ask what’s included and how long the hygiene visit lasts.

Comfort options for nervous patients

If the thought of a routine dental cleaning makes you anxious, you’re not alone — and your visit can be made genuinely comfortable. We welcome nervous patients and tailor the scale and polish to your pace, explaining each step so there are no surprises. Many practices also offer sedation dentistry for those with significant dental anxiety.

Topical numbing or local anaesthetic: to calm sensitive areas.
Go-slow protocol: clear stop‑signals, shorter or staged appointments, and rest breaks.
Gentle techniques: soft polishing pastes and careful instrument choice.
Distraction and support: bring headphones, practise breathing, and agree the plan in advance.
Sedation options (where appropriate): discuss with your dentist if anxiety is severe.

How to prepare for your appointment

A little preparation makes your routine dental cleaning smoother and more comfortable. Aim to arrive a few minutes early, and be ready to discuss any concerns so your clinician can tailor the visit to you.

Clean as normal: Brush and clean between teeth beforehand; don’t rinse with water straight after brushing.
Eat as usual: If fluoride varnish is applied, you’ll need to avoid eating/drinking for about 30 minutes afterwards.
Bring essentials: Medication list, medical conditions, allergies and any dental appliances/retainers.
Flag sensitivities/anxiety: We can use numbing gel, go slower, or discuss sedation if appropriate.
Wear comfortable clothing and minimal lip products for easier access to the gumline.

Key takeaways

A routine dental cleaning is a simple, preventive scale and polish that removes plaque and tartar your brush can’t, usually in 30–60 minutes. How often you need it is personalised (often six‑monthly), and deep cleaning is reserved for gum disease. X‑rays are taken when due, and side effects are usually mild and short‑lived.

Scale and polish: removes plaque/tartar above the gumline; polishing smooths enamel.
Timing: allow 30–60 minutes; longer if it’s your first visit or there’s heavy build‑up.
Frequency: risk‑based; many do well with six‑monthly hygiene visits.
Deep clean vs routine: deep cleaning treats disease below the gumline with local anaesthetic.
X‑rays: taken only when due (often 6–36 months) to guide care.
Side effects: brief sensitivity/tender gums are common; seek advice if pain persists.
