Dental Plaque: What It Is and How to Remove It

Dental plaque is a sticky film of bacteria that forms on your teeth every day everyone gets it, and that's normal. The problem isn't plaque itself, it's what happens when it's not removed regularly: it can lead to cavities, gum disease, and bad breath. Ocotillo Trails Family Dentistry helps patients in San Tan Valley, Gilbert, and Mesa stay ahead of plaque buildup with routine cleanings and exams.

What Causes Dental Plaque

Plaque forms when bacteria in your mouth mix with sugars and starches from food and drinks—things like bread, juice, soda, and pasta. These bacteria break down the carbohydrates and release acids, and the combination of bacteria, acid, and food debris forms the sticky film known as plaque.

Where Plaque Forms

Plaque can be classified by where it sits on the tooth.

Supragingival Plaque

Supragingival plaque forms above the gumline, on the visible part of your teeth. This is the plaque you can usually see and feel.

Subgingival Plaque

Subgingival plaque forms below the gumline. It’s harder to notice and harder to remove at home, which is part of why it tends to cause more gum-related problems.

Symptoms of Plaque Buildup

A fuzzy or “fuzzy-sweater” feeling on your teeth when you run your tongue over them
A soft, white-to-pale-yellow film along the gumline
Bad breath that doesn’t improve with brushing
Red, swollen gums that bleed when you brush or floss
Tooth staining, especially near the gumline

Plaque vs. Tartar

Plaque is a soft, sticky film that forms every day and can be removed at home through consistent brushing and flossing.

If plaque isn’t removed, it can harden into tartar—also called calculus—within a day or two.

Once Plaque Becomes Tartar

Once plaque has hardened into tartar, brushing and flossing can no longer remove it—only a dentist or hygienist can.

Tartar often starts white or pale yellow, but over time it can darken from coffee, tea, red wine, or tobacco use.

Home care alone won’t remove tartar; that part requires a professional cleaning.

What Happens If Plaque Isn't Removed

Plaque—and the tartar it turns into—raises the risk of cavities, gum disease, persistent bad breath, and more advanced dental problems.

Common Plaque-Related Problems

Cavities and tooth decay
Gingivitis and more advanced gum disease
Persistent bad breath

How It's Diagnosed

Your dentist or hygienist can usually spot plaque and tartar during a routine exam simply by looking and feeling around your teeth and gumline.

Plaque-Disclosing Tools

Some offices also use a plaque-disclosing solution or tablet—a harmless dye that temporarily stains plaque a visible color, making it easy to see exactly where your brushing is missing spots.

Dental Plaque Removal and Prevention at Home

1. Brush Thoroughly

Brush twice a day with a soft-bristled brush and fluoride toothpaste.

2. Clean Between Teeth

Floss once a day, or use a water flosser to clean between teeth and along the gumline.

3. Rinse and Limit Plaque Fuel

Drink water with meals and snacks to help rinse away food particles, and limit sugary and starchy foods and drinks, especially between meals.

4. Keep Regular Cleanings

Keep up with regular dental cleanings. Even great home care can’t remove plaque that’s already hardened into tartar.

How We Remove Plaque and Tartar

During a routine cleaning, we remove plaque and tartar buildup, including in spots that are difficult to reach with a toothbrush alone, like below the gumline. If plaque-related issues like gum disease or cavities are already present, we’ll walk you through the right next steps. Regular cleanings through our General & Preventive Dentistry team are the foundation of staying ahead of plaque long-term.

Frequently Asked Questions

Can you remove plaque at home?

Yes, soft plaque can be removed with regular brushing and flossing. But once it hardens into tartar, home care can’t remove it; that requires a professional cleaning.

What's the difference between plaque and tartar?

Plaque is a soft, sticky film you can remove yourself with brushing and flossing. Tartar is hardened plaque that’s bonded to the tooth and can only be removed by a dentist or hygienist.

Can dental plaque cause bad breath?

Yes. The bacteria in plaque produce odor as a byproduct, which is one of the more common causes of bad breath that doesn’t improve with brushing alone.

How often should I get my teeth cleaned to remove plaque?

Most people benefit from a professional cleaning every six months, though your dentist may recommend more frequent visits if you tend to build up plaque or tartar quickly.
