You brush every day, but by the afternoon your teeth feel a little fuzzy again. That soft, sticky film is plaque, and everyone gets it. The good news is that you can remove plaque from your teeth at home with the right daily habits. The key is to clear it away before it has a chance to harden.
Plaque is the main cause of cavities and gum disease. Once it hardens into tartar, brushing and flossing can’t remove it, and only a dental professional can. Below, we’ll explain what plaque is, how to get rid of it at home, and the signs that it’s time to book a professional cleaning.
What Is Plaque?
Plaque is a sticky, colorless or pale yellow film of bacteria that forms on your teeth all day long. It builds up fastest along the gumline, between teeth, and on the chewing surfaces of your back teeth.
Your mouth is home to hundreds of types of bacteria. When you eat or drink, especially foods with sugar or starch, some of those bacteria feed on what’s left behind. As they multiply, they form a layer that clings to your teeth. Within hours of brushing, a new layer is already starting to form.
You can’t always see plaque, but you can usually feel it. If your teeth feel rough or fuzzy when you run your tongue over them, that’s plaque.
Plaque vs. Tartar: What’s the Difference?
Plaque is soft and can be removed with a toothbrush and floss. But if plaque stays on your teeth too long, minerals from your saliva harden it into tartar, also called calculus. This can start in as little as a day or two.
Tartar is hard, crusty, and often yellow or brown. It bonds tightly to your enamel and can form above and below the gumline. Because it’s so firmly attached, tartar can’t be brushed or flossed away. It takes special tools and training to remove it safely.
Tartar also has a rough surface, which makes it easier for even more plaque to stick. That’s why small buildups tend to grow over time.
Why Plaque Is Bad for Your Teeth and Gums
Plaque is more than a cosmetic problem. The bacteria in plaque cause most of the common problems dentists see every day:
- Cavities. Plaque bacteria make acids that wear away enamel. Over time, that creates weak spots and then holes in your teeth.
- Gingivitis. Plaque along the gumline irritates the gums, making them red, puffy, and likely to bleed when you brush or floss. This early stage of gum disease is usually reversible with good home care and a cleaning.
- Periodontitis. If gingivitis isn’t treated, the infection can spread below the gumline. Gums pull away from the teeth, and the bone that holds teeth in place can break down. This advanced form of gum disease is a leading cause of tooth loss in adults.
- Bad breath. Bacteria in plaque release odor-causing compounds, so heavy plaque often means stubborn bad breath.
- Stains. Plaque and tartar soak up stains from coffee, tea, red wine, and tobacco, making teeth look yellow or dull.
Gum health also matters beyond your mouth. Research has linked gum disease with other health conditions, including diabetes and heart disease. Keeping plaque under control is one of the easiest ways to protect both your smile and your overall health.
How to Remove Plaque at Home
The best way to remove plaque is to disrupt it every day, before it has time to harden. These habits make the biggest difference.
Brush the Right Way, Twice a Day
Brush for two full minutes, twice a day, with a soft-bristled toothbrush. Most people brush for far less time than they think, so a timer or a song can help.
Technique matters as much as time:
- Hold the brush at a 45-degree angle toward your gumline, where plaque likes to hide.
- Use gentle, short strokes or small circles. Scrubbing hard doesn’t remove more plaque, and it can wear down enamel and irritate your gums.
- Brush every surface: the outside, the inside, and the chewing surfaces of each tooth.
- Don’t forget the backs of your front teeth and the far sides of your back molars.
- Brush your tongue, or use a tongue scraper, to remove bacteria that cause bad breath.
Replace your toothbrush, or your electric brush head, every three to four months, or sooner if the bristles look frayed. Worn bristles don’t clean well.
Clean Between Your Teeth Every Day
A toothbrush can’t reach the tight spaces between your teeth, and that’s where a lot of plaque builds up. Cleaning between your teeth once a day removes plaque your brush misses and is one of the best ways to prevent gum disease.
You have several options:
- String floss. Curve the floss into a C shape around each tooth and gently slide it just below the gumline. Here’s a guide on how to floss the right way.
- Floss picks. Handy for kids, on-the-go cleaning, or anyone who finds string floss tricky.
- Interdental brushes. Tiny brushes that work well for wider gaps, braces, and bridges.
- Water flossers. A good choice for people with braces, implants, or sensitive gums. Many people find them easier to use every day.
The best tool is the one you’ll actually use. If your gums bleed a little when you start flossing, don’t stop. Bleeding usually improves within a week or two of daily cleaning as your gums get healthier. If it doesn’t, see your dentist.
Consider an Electric Toothbrush
A manual toothbrush works well when it’s used correctly. But many people find an electric toothbrush makes it easier to remove plaque. Studies have found that powered brushes, especially those with rotating or oscillating heads, tend to remove more plaque than manual brushes.
Many electric brushes also have built-in two-minute timers and pressure sensors that warn you if you’re brushing too hard. These features are especially helpful for kids, older adults, and anyone with limited hand strength.
Use Fluoride Toothpaste and the Right Rinse
Fluoride toothpaste doesn’t remove plaque by itself, but it strengthens enamel so it can better resist the acids plaque produces. That’s especially important in Hawaii, where most public tap water doesn’t contain added fluoride.
A tartar-control toothpaste can help slow new tartar from forming, though it can’t remove tartar that’s already there. An antimicrobial or antiplaque mouth rinse can also help reduce bacteria. Rinses are a helpful extra, not a replacement for brushing and flossing.
Watch What and When You Eat
Plaque bacteria thrive on sugar and refined starches. Cutting back on sweets, soda, juice, and sticky snacks gives them less to feed on.
How often you snack matters too. Every time you eat or drink something sugary, plaque bacteria make acid for about 20 minutes or more. Sipping a sweet drink all afternoon or grazing on snacks keeps that cycle going. Try to keep treats to mealtimes, and drink water afterward to rinse away leftover food.
Chewing sugar-free gum, especially gum with xylitol, after meals can also help. It boosts saliva flow, which naturally washes away food and neutralizes acid.
Check Your Work with Disclosing Tablets
Want to see where you’re missing plaque? Disclosing tablets or solutions are chewable tablets or rinses that temporarily stain plaque pink or purple. After you brush, chew a tablet and look in the mirror. Any colored spots show areas that need more attention. They’re also a fun way to teach kids how to brush well.
Can You Remove Tartar at Home?
No. Once plaque hardens into tartar, it’s too firmly attached to remove with a toothbrush, floss, or rinse.
You may see videos online of people scraping their teeth with metal picks or scalers, or using harsh home remedies. Please don’t try these. Without training, it’s easy to scratch your enamel, cut your gums, or push tartar further below the gumline, where it causes more damage. Acidic DIY remedies, such as straight lemon juice or vinegar, can erode enamel. Rough powders can wear it away.
The safe way to remove tartar is a professional cleaning. Your hygienist has the tools and training to remove it gently, including from below the gumline, where you can’t see or reach.
Signs It’s Time for a Professional Cleaning
Even with great home care, everyone needs regular professional cleanings. Some signs mean it’s a good idea to book sooner rather than later:
- Your gums bleed when you brush or floss
- Your gums look red, swollen, or tender
- You see hard yellow or brown buildup, especially behind your lower front teeth or along the gumline
- You have bad breath that doesn’t go away after brushing
- Your teeth look more stained or dull than usual
- Your gums seem to be pulling away from your teeth, or your teeth look longer
- You notice new sensitivity to hot or cold
- Your teeth feel loose, or your bite feels different
- It’s been more than six months since your last cleaning
Some of these signs, like receding gums or loose teeth, can point to more advanced gum disease. If you notice them, don’t wait. Early treatment is easier, more comfortable, and less costly.
What Happens During a Dental Cleaning?
If it’s been a while, you may be wondering what to expect. A routine cleaning is quick and usually comfortable. It typically includes:
- An exam. Your hygienist checks your teeth and gums, measures gum health, and looks for signs of decay, gum disease, and other concerns. Your dentist also does an exam and may take X-rays if needed.
- Scaling. Your hygienist uses special instruments to gently remove plaque and tartar from your teeth, along the gumline, and just below it.
- Polishing. A gritty polishing paste removes surface stains and smooths your teeth, which makes it harder for new plaque to stick.
- Flossing. Your hygienist flosses between your teeth to clear away any leftover debris.
- Fluoride. Many patients, especially kids and those at higher risk for cavities, benefit from a professional fluoride treatment.
- Personal tips. Your hygienist can point out spots you tend to miss and recommend the best tools for your mouth.
Regular Cleaning vs. Deep Cleaning
A regular cleaning, also called a prophylaxis, is for patients with healthy gums. It focuses on the teeth and the area at and just below the gumline.
If tartar has built up deep below the gumline and gum disease has set in, your dentist may recommend a deep cleaning, also called scaling and root planing. This treatment removes tartar from the root surfaces below the gums and smooths the roots so the gums can heal and reattach. It’s often done in two or more visits, and the area is numbed for comfort.
After a deep cleaning, many patients move to periodontal maintenance cleanings every three to four months to keep gum disease under control.
How Often Should You Get a Cleaning?
For most people, a cleaning and checkup every six months works well. Many dental plans cover two cleanings a year, so be sure to use your benefits.
Some people need cleanings more often, such as every three or four months. This includes people who:
- Have a history of gum disease
- Build up tartar quickly
- Have diabetes
- Smoke or use tobacco
- Are pregnant, since hormone changes can make gums more prone to inflammation
- Have braces, implants, or other dental work that makes cleaning harder
Your dentist and hygienist will recommend the schedule that’s right for you.
