Plaque is a soft layer of bacteria that forms on your teeth, while tartar is plaque that has hardened and attached to the tooth surface. Plaque can usually be removed at home with brushing and cleaning between your teeth. Tartar is different. Once it has hardened, brushing and flossing cannot remove it.
That difference is one reason professional dental cleanings matter. A dental hygienist can remove hardened deposits from areas that are difficult to clean at home and check for signs of gum inflammation or other oral health problems. A regular dental checkup in Newmarket also gives your dental team an opportunity to assess your teeth and gums and identify concerns that may need attention.
What Is Plaque?
Plaque is a sticky bacterial film that develops on your teeth throughout the day. You may not notice it because it is often clear or difficult to see, but it can collect along the gumline and between teeth.
Your mouth naturally contains bacteria. When these bacteria mix with saliva and food particles, they can form a biofilm on the teeth. The longer plaque stays in place, the more difficult it can become to keep the area clean.
Plaque is not something you can prevent from forming altogether. It starts building up again after you brush. The goal is to remove it regularly before it causes problems or becomes mineralized.
How Plaque Builds Up on Your Teeth
Plaque tends to collect in places that are easy to miss, especially:
- Along the gumline
- Between the teeth
- Around crowded teeth
- In deep grooves on the chewing surfaces
- Around some dental restorations or appliances
Brushing cleans many of the exposed surfaces of your teeth, but a toothbrush cannot reach every area equally well. That is why cleaning between the teeth is part of good daily oral care.
Plaque also plays a role in tooth decay and gum inflammation. Bacteria in plaque can produce acids after you consume sugars and starches, while plaque along the gumline can irritate the surrounding gum tissue.
Why Plaque Needs Regular Removal
Fresh plaque is relatively soft, which is why it can usually be disrupted with brushing and interdental cleaning.
Leaving it in place gives it more time to accumulate and, in some areas, become mineralized. Regular removal helps limit the amount of plaque that remains on your teeth and reduces the buildup that can eventually become tartar.
What Is Tartar?
Tartar is hardened plaque that has become mineralized and firmly attached to the teeth. Dentists and dental hygienists also call it dental calculus.
The change from plaque to tartar happens when minerals in saliva become incorporated into plaque. The resulting deposit is much harder than ordinary plaque and cannot be brushed away.
Tartar may develop above the gumline or below it. It can also have a rough surface that gives new plaque more places to collect.
How Plaque Turns Into Tartar
Some people develop tartar faster than others.Saliva, oral hygiene, tooth position, and areas that are difficult to clean can all affect how quickly calculus forms
How quickly calculus develops can vary depending on factors such as saliva, tooth position, oral hygiene, and areas that are difficult to clean. Some people notice tartar buildup more quickly than others even when they brush regularly.
Once mineralization has occurred, home care can still help prevent additional plaque from accumulating, but it cannot remove the hardened deposit that is already there.
Where Tartar Commonly Builds Up
Tartar is often found along the gumline and in areas where saliva enters the mouth.
For example, deposits may be noticeable behind the lower front teeth. They can also develop between teeth or around areas that are difficult to clean thoroughly.
Tartar often feels hard or rough and does not come off when you brush. Unlike plaque, it does not simply wipe away.
Plaque vs Tartar: What’s the Difference?
Plaque is soft and can usually be removed at home. Tartar is mineralized plaque that has hardened and generally needs professional removal.
| Feature | Plaque | Tartar |
|---|---|---|
| What is it? | Bacterial biofilm | Hardened, mineralized plaque |
| Texture | Soft or sticky | Hard and rough |
| Forms | Continuously on teeth | When plaque mineralizes |
| Can brushing remove it? | Usually | No |
| Can floss remove it? | Yes, between teeth | No |
| Professional cleaning | Helps prevent buildup | Usually needed for removal |
Tartar starts as plaque, but once it hardens, brushing and flossing can no longer remove it. You should still brush and clean between your teeth, but those habits will not remove tartar that has already hardened.
Can Brushing Remove Tartar?
No. Brushing can remove plaque, but it cannot remove tartar that has already hardened on your teeth.
Scrubbing harder will not remove tartar and can irritate your gums. In fact, aggressive brushing can irritate the gums without removing the calculus.
A good brushing routine is still essential because it helps control the plaque that forms around existing tartar and on the rest of the teeth. But if you can feel a hard deposit that does not disappear with normal brushing, it may need to be removed professionally.
What Brushing Can Do
Brushing twice a day with fluoride toothpaste helps remove plaque from the surfaces your toothbrush can reach.
To remove plaque more effectively:
- Brush the outer, inner, and chewing surfaces of your teeth.
- Spend time along the gumline.
- Use gentle pressure rather than scrubbing aggressively.
- Replace your toothbrush or brush head when it becomes worn.
- Clean between your teeth every day.
Brushing cleans the surfaces of your teeth, while flossing or interdental cleaning reaches between them.
Why Professional Dental Cleaning Matters
Professional dental cleaning matters because hardened tartar cannot be removed with a toothbrush or floss. A dentist or dental hygienist can remove these deposits with instruments designed for the job while also checking the condition of your teeth and gums. This is an important part of professional teeth cleaning, especially when tartar has built up in areas that are difficult to reach at home.
Some tartar forms in places you cannot easily see or reach at home.
Calculus can develop in areas that are difficult to reach or inspect at home. During a dental visit, your dental professional can assess the gumline and look for signs of inflammation, bleeding, recession, or other changes that may need attention.
You still need to brush and clean between your teeth every day. Professional cleaning simply removes hardened buildup that you cannot remove at home. Home care controls plaque between appointments, while professional care removes hardened deposits that home care cannot remove.
What Happens During a Professional Cleaning?
During a routine cleaning, the dental team checks your teeth and gums and removes plaque, tartar, and surface buildup.
Depending on the amount and location of the buildup, a dental hygienist may use hand instruments, powered instruments, or a combination of techniques.
The teeth may then be polished to remove certain surface stains and leave the tooth surfaces feeling smoother.
Your hygienist can also show you where plaque is building up and suggest ways to improve your brushing or interdental cleaning.

Does Tartar Removal Hurt?
Tartar removal is often well tolerated, but some people experience sensitivity or discomfort during cleaning. If you are wondering does dental cleaning hurt, the answer can depend on the amount of tartar, where it has built up, and how sensitive or inflamed your gums are.
How comfortable the cleaning feels depends on the amount of tartar, where it has built up, and how sensitive or inflamed your gums are.
If you have sensitive teeth or are worried about discomfort, let your dental hygienist know before the cleaning. They can explain what to expect and adjust the approach when appropriate.
Can Tartar Affect Your Gums?
Tartar creates a rough surface where plaque can collect around the gumline, making the area harder to keep clean. Professional cleaning for gums can help remove hardened buildup and make it easier to maintain healthy gum tissue.
Plaque is a major factor in gingivitis. When plaque remains around the gums, the tissue may become red, swollen, tender, or prone to bleeding.
If periodontal disease develops, the inflammation can affect the tissues and bone that support the teeth. Tartar is one part of this picture, but it is not accurate to say that tartar alone causes periodontal disease.
Other factors can affect gum health as well, including oral hygiene, smoking, diabetes, genetics, and individual susceptibility.
Signs Your Gums May Need Attention
Keep an eye out for changes such as:
- Gums that bleed regularly
- Red or swollen gums
- Persistent bad breath
- Gum tenderness
- Receding gums
- Loose teeth
- Changes in how your teeth fit together
- Persistent discomfort
These signs do not necessarily mean you have periodontal disease. A dental examination is needed to determine the cause.
Routine Dental Cleaning vs Deep Cleaning
Dental cleaning and deep cleaning are not the same type of treatment. A routine dental cleaning focuses on removing plaque, tartar, and surface buildup as part of preventive care. Deep cleaning, also called scaling and root planing, is a periodontal treatment used when gum disease requires cleaning below the gumline.
| Routine Dental Cleaning | Deep Cleaning |
|---|---|
| Usually preventive care | Periodontal treatment |
| Removes plaque and calculus from accessible areas | Addresses deposits below the gumline when indicated |
| Typically part of ongoing dental care | Used when periodontal findings support it |
| Does not automatically involve root planing | Includes scaling and root planing |
A deep cleaning is not recommended simply because tartar is visible.
Your dentist considers the condition of your gums, periodontal measurements, the location of deposits, and other clinical findings before recommending periodontal treatment.
How Can You Prevent Plaque and Tartar Buildup?
Regular plaque removal helps reduce the amount of tartar that forms on your teeth.
You cannot completely stop plaque from forming. It develops naturally throughout the day. Regular brushing and interdental cleaning help remove plaque before it can build up and mineralize.
Brush Twice a Day
Brush your teeth twice daily with fluoride toothpaste. Rather than brushing harder, focus on reaching all tooth surfaces and the gumline.
If the same areas keep collecting plaque, your dentist or hygienist can check your brushing technique and show you how to clean them more effectively.
Clean Between Your Teeth
Plaque can remain between teeth even when the visible surfaces look clean.
Depending on your mouth and the spaces between your teeth, you may use:
- Dental floss
- Interdental brushes
- A water flosser
- Another method recommended by your dental professional
Cleaning between your teeth removes plaque from areas your toothbrush cannot reach.
Keep Up With Professional Cleanings
Even with good home care, some people develop calculus more readily than others.
Regular dental visits allow hardened deposits to be removed and give your dental team an opportunity to monitor your gums and teeth. Learn more about how often you should get a dental cleaning and what can affect your recommended schedule.How often you need a cleaning depends on your oral health, gum health, and risk factors.
When Should You See a Dentist?
A visit to a dentist in Newmarket may be appropriate if you notice hard buildup that does not come off with brushing or changes in your gums.
Make an appointment if you notice:
- Hard deposits around the gumline
- Frequent gum bleeding
- Swollen or tender gums
- Persistent bad breath
- Gum recession
- Loose teeth
- Tooth sensitivity or discomfort
- A noticeable change in your oral health
If you are due for a cleaning, professional evaluation can determine whether a routine dental cleaning is appropriate or whether your gums need additional care.
Plaque can usually be removed with daily brushing and interdental cleaning. Tartar is different,once it hardens, it needs professional removal. Plaque is soft and can usually be removed with brushing and interdental cleaning. Tartar is mineralized plaque that cannot be brushed or flossed away once it has hardened.
Daily oral hygiene helps prevent new buildup, while professional cleaning removes calculus that has already formed. If you are noticing persistent tartar, bleeding gums, or other changes around your teeth, a dental examination can help determine what type of care you need.

Frequently Asked Question
Plaque is a soft bacterial film that forms on your teeth, while tartar is plaque that has hardened through mineralization. Plaque can usually be removed with brushing and cleaning between your teeth. Tartar is firmly attached to the tooth surface and generally requires professional removal.
No, brushing cannot remove established tartar. Brushing removes soft plaque and helps prevent additional buildup, but mineralized calculus is too hard to brush away. If you notice a hard deposit that remains after brushing, a dental professional can remove it using appropriate instruments.
You should not try to scrape tartar off your teeth at home. Using sharp objects or dental instruments without professional training can injure your gums or damage tooth surfaces. Home care should focus on removing plaque and preventing new deposits rather than trying to remove established calculus.
Daily brushing reduces plaque but does not guarantee that every area is cleaned completely. Plaque can remain between teeth, along the gumline, or in areas that are difficult to reach. Saliva and individual differences also affect how readily calculus forms. Interdental cleaning and professional cleanings can help manage buildup.
No. Having tartar does not automatically mean that you need a deep cleaning. Routine cleaning may be appropriate when calculus is present without evidence of periodontal disease. Scaling and root planing is used when clinical findings indicate that periodontal treatment below the gumline is needed.
Tartar can make plaque control more difficult, but tartar alone does not mean that you have gum disease. Plaque around the gumline can contribute to gingivitis, while periodontal disease involves inflammation and damage to the tissues supporting the teeth. A dentist needs to evaluate the gums to determine whether disease is present.
Yes, professional cleaning can still be useful even when you have good daily oral hygiene. Brushing and interdental cleaning control soft plaque, but they cannot remove tartar once it has hardened. Professional visits also allow your dental team to assess your teeth and gums for changes that may not be obvious at home.
