Professional teeth cleaning, also called scaling , is an oral hygiene treatment performed by a dentist or dental hygienist to remove plaque, tartar, and bacteria that a toothbrush cannot remove.
It is a safe, painless procedure that is essential for the prevention of gingivitis and periodontitis , but also useful for avoiding the formation of tooth decay.
Many people think that good home hygiene is enough, but even with regular brushing, some plaque tends to accumulate in hard-to-reach areas, turning into tartar over time.
How tartar forms
After each meal, bacteria in the mouth combine with food debris and salivary proteins to form plaque , a soft, sticky film.
If it is not removed, over time it mineralizes due to the minerals contained in saliva (such as calcium phosphate), turning into tartar , which is much more difficult to remove with a toothbrush.
💬 “Scaling isn't just a cosmetic issue: it's a true preventative therapy. It keeps your mouth healthy, reduces inflammation, and preserves your teeth over the long term.”
— Dr. Pietro Pastore, Co-Founder CleanOS
How to get a professional teeth cleaning
Professional dental hygiene, or scaling , is a real therapy performed by the dentist or dental hygienist .
It is not a standard treatment that is the same for everyone: each session is customized based on the condition of the mouth and the patient's needs.
After an initial assessment , the professional decides which tools and techniques to use, choosing the most effective and comfortable solution for each case.
Techniques and tools used
Today, alongside traditional methods, GBT (Guided Biofilm Therapy) is increasingly used, a technology that has revolutionized professional oral hygiene.
This completely painless and delicate method uses specific powders and controlled air jets to remove biofilm, plaque and pigmentation, respecting teeth and gums.
Depending on the needs, the professional can use:
-
Hand tools (such as curettes), for more delicate areas.
-
Ultrasonic instruments (scaler), to break down tartar with high-frequency vibrations.
-
Customized combinations of GBT, ultrasound, and hand tools for deeper cleaning.
💡 In the most up-to-date Italian clinics, GBT is increasingly popular because it allows for effective cleaning without discomfort or pain.
Polishing
After tartar removal, polishing is performed — only if necessary — with specific abrasive pastes or powders.
This step removes surface stains and smoothes the enamel, reducing the ability of plaque to re-adhere.
Fluoride application
In some cases, especially in younger patients or when areas of demineralization are present , topical fluoride is applied to strengthen the enamel and protect it from acids produced by bacteria.
Use of chlorhexidine
Before or after the session, the professional may administer a rinse with chlorhexidine , a powerful antiseptic that reduces the bacterial load in the mouth.
In cases of gingivitis or periodontitis , it may be advisable to continue at home with specific mouthwashes to maintain the antibacterial effect for up to 12 hours.
Difference between teeth cleaning and scaling
Scaling is the technical phase of professional dental cleaning: it consists of the mechanical removal of tartar.
Teeth cleaning , on the other hand, also includes polishing, fluoride and gum evaluation.
In short: scaling is a part of professional cleaning, but it is not the entire process.
Benefits of scaling
Regular scaling allows you to:
-
Remove plaque and tartar.
-
Prevent gingivitis, periodontitis and tooth decay.
-
Reduce bad breath and improve the appearance of your smile.
-
Maintain the effectiveness of aesthetic and orthodontic treatments for longer.
Furthermore, good oral hygiene also promotes general health : several studies have highlighted a link between chronic oral infections and pathologies such as cardiovascular disease or diabetes.
Scaling before and after: what's different?
After scaling, teeth tend to appear whiter and smoother, gums less swollen, and breath fresher. Other times, teeth appear rough, especially behind the lower incisors.
Research shows that periodontal disease patients who regularly undergo professional cleanings every three months are 5.6 times less likely to lose teeth than those who neglect them.
A “before and after” comparison clearly shows how even a single session improves aesthetics and oral health .
How often should you have your teeth cleaned?
The recommended frequency varies based on needs:
-
Every 6 months: for those with good oral health.
-
Every 3–4 months: for those with gingivitis or rapid tartar buildup.
-
During pregnancy: Cleansing is safe and recommended in every trimester.
⏱️ Leaving too much time between scaling increases the difficulty of the treatment and post-procedure sensitivity.
Teeth Cleaning During Pregnancy: Why It's Important
Pregnancy is a time of great changes for the entire body — and the oral cavity is no exception .
During pregnancy, the increase in the hormones estrogen and progesterone can change the vascularization of the gums , making them more sensitive and prone to inflammation.
According to experts in dentistry and pediatric dentistry, up to 60% of pregnant women can develop pregnancy gingivitis , and approximately 40% may develop forms of periodontitis if correct oral hygiene is not maintained.
Common changes and risks
-
Bleeding gums : linked to an increased inflammatory response to plaque microorganisms.
-
Increased tooth sensitivity: due to hormonal changes and frequent episodes of reflux or vomiting.
-
Enamel erosion: caused by stomach acids and the consumption of sugary foods during nausea.
If left uncontrolled, these factors can promote the onset of tooth decay and gum inflammation .
How to prevent ailments during pregnancy
The Ministry of Health guidelines recommend not postponing dental treatments during pregnancy: professional oral hygiene sessions (scaling) can be safely performed in all trimesters , preferably between the 14th and 20th week.
During cleaning, the dentist can use ultrasonic or manual instruments , just like for any other patient, taking care only to choose comfortable positions and delicate procedures.
The bond between mother and newborn
The mother's oral health directly affects that of the newborn .
Reducing the amount of cariogenic bacteria in the mother's mouth helps delay the colonization of the baby's mouth after birth.
Common gestures such as kissing the newborn on the mouth or tasting the baby's food with the same spoon can transfer the microorganisms responsible for tooth decay.
Maintaining a healthy mouth during pregnancy is therefore a form of early prevention for the child.
Oral hygiene for newborns: where to start
From the first days of life, it is useful to clean the newborn's gums and tongue after each feeding with a moistened gauze or a silicone finger.
From six months onwards , with the appearance of the first teeth, it is important to introduce a soft-bristled toothbrush and toothpaste with fluoride (at least 1000 ppm), twice a day.
The Ministry of Health recommends the first dental visit between 18 and 24 months , even in the absence of problems, to educate parents on correct oral hygiene practices from childhood.
How much does teeth cleaning cost?
The cost of professional teeth cleaning in Italy varies on average between €60 and €150 per session.
The rate may change based on several factors, including:
-
General condition of the mouth and amount of plaque or tartar present.
-
Techniques and tools used , such as stain removing systems, specific powders or GBT (Guided Biofilm Therapy) , which uses more advanced and delicate technologies.
-
Additional applications , such as fluoride treatments ( fluoride prophylaxis ) to strengthen the enamel.
-
Duration of the service , which varies according to the complexity of the case.
-
City and type of dental practice , which can affect operating costs.
In patients with periodontal disease , a more thorough hygiene protocol may be necessary, with cleaning sessions under local anesthesia in the initial stages, followed by periodic maintenance recalls .
In these cases, the overall cost may be higher , but it represents a fundamental investment for the long-term health of your teeth and gums .
CleanOS Team Tip: Always ask for a personalized quote—a thorough oral health assessment is the first step in understanding the frequency and type of cleaning best for you.
Frequently asked questions about scaling
Does scaling hurt?
No. It may only cause mild discomfort if your gums are inflamed or your teeth are very sensitive.
After how long can I eat?
After about 30–60 minutes. It's best to avoid colored or sugary foods for a few hours.
Can you smoke after scaling?
It's best to wait at least two hours: smoking irritates the gums and promotes new pigmentation.
Can I do scaling together with whitening?
Yes, in fact it is recommended: removing plaque and tartar first improves the effectiveness of the whitening.
Conclusions
Professional dental cleaning is one of the most effective practices for maintaining healthy teeth and gums.
Regular scaling and good daily oral hygiene habits help prevent tooth decay, inflammation, and gum problems.
💡 Prevention starts here: proper daily hygiene and regular scaling keep gums healthy, teeth strong, and a bright smile.
