What a Professional Clean Involves
A clean at the practice has three parts. Hardened deposits are removed, the teeth are polished, and fluoride is applied.
It is not a tidier version of brushing at home. Each part does something you cannot do yourself.
The clean usually follows your check-up in the same visit, once your dentist knows what is there.
Why Tartar Has to Be Scaled Off
Plaque is soft, and brushing removes it. Left for a day or two, it absorbs minerals from saliva and hardens into tartar.
Tartar bonds to the tooth. No amount of brushing shifts it, and no toothpaste dissolves it.
Its surface is rough and porous, so it holds more plaque against the tooth and the gum. That is what keeps the gum inflamed.
If tartar has gone below the gum line and pockets have formed, you need root planing rather than a routine clean.
What Polishing Does
Polishing removes surface stain from tea, coffee, red wine and smoking. It is done with a soft cup and a fine paste.
The visible effect is cosmetic, and teeth do look brighter afterwards. The functional effect matters more.
A polished surface is smooth, and plaque takes longer to attach to smooth enamel. The clean therefore lasts longer.
Polishing does not change the natural colour of the tooth. For that you need whitening, which works inside the enamel.
What Fluoride Does
Fluoride rebuilds enamel that acid has started to weaken. It puts minerals back into the surface.
The rebuilt surface is also more acid resistant than the original. It stands up better to the next attack.
An early white spot can be reversed this way, before any hole forms. That is the one stage of tooth decay that can still be undone.
The varnish used at the practice is far stronger than toothpaste. It is painted on and left to work.
Who Benefits Most from Fluoride
- Children and teenagers, whose enamel is still maturing.
- Anyone who gets cavities easily.
- People with receding gums, where softer root surface is exposed.
- Anyone with a dry mouth, often caused by medication.
- Patients wearing braces, where cleaning is harder.
- People with several crowns or bridges to protect.
Dry mouth is the risk most people underestimate. Saliva neutralises acid constantly, so losing it removes your main natural defence.
What the Appointment Is Like
- Your gums are checked, so the clean matches what they need.
- Tartar is removed with an ultrasonic scaler, hand instruments, or both.
- The teeth are polished, one surface at a time.
- Fluoride varnish is painted on and left to set.
- You are shown the spots you are missing at home.
The scaler sprays water and vibrates. It is noisy rather than painful, though tender gums can be sensitive.
The last step is worth paying attention to. Being shown exactly where you miss is more useful than being told to brush better.
Afterwards
Avoid eating and drinking for about thirty minutes so the fluoride stays on the teeth. Your dentist will tell you the exact time.
Keep off hot, hard and crunchy food for the rest of the day. Gums can feel tender if there was a lot of tartar.
Some sensitivity to cold for a day or two is normal. It settles as the gums recover.
How Often
Every six months suits most people, alongside the check-up. Some build tartar faster and need three or four monthly visits.
Smokers, people with a history of gum disease, and patients in orthodontic treatment usually come more often.
Your dentist sets the interval from what your gums are doing, not from a fixed rule.
Fluoride at Home
Use a fluoride toothpaste twice a day. Spit it out and do not rinse with water, because rinsing washes the fluoride straight off.
Children need a smear until about three, then a pea-sized amount. Supervise brushing until around seven.
Does It Hurt
A routine clean is not painful for most people. The scaler feels like vibration and cold water.
Sensitivity is worse when gums are already inflamed, which is usually a sign the clean was overdue. Coming more regularly makes each visit easier.
Tell your dentist if you find it uncomfortable. Numbing gel or local anaesthetic can be used.
