Plaque vs. Tartar, Identifying the Differences

Patients often use the terms plaque and tartar interchangeably, but they are actually quite different. Understanding how each one forms and affects oral health can make daily hygiene routines more meaningful and effective.

What is Plaque?

Plaque is a soft, sticky film made up of bacteria, food particles, and saliva. It forms constantly on the teeth and along the gumline. Every time we eat, especially foods containing sugar or starch, the bacteria in plaque produce acids that attack tooth enamel. Over time, these acid attacks can lead to cavities and gum inflammation if plaque is not removed through brushing and flossing.

The good news about plaque is that it is removable at home. Brushing twice a day and flossing daily are usually enough to keep plaque under control for most people. However, when plaque is left behind for too long, it begins to harden.

This is where tartar comes in

Tartar, also called calculus, forms when plaque mineralizes on the teeth. Saliva contains minerals that cause plaque to harden within about 24 to 72 hours. Once tartar forms, it cannot be removed with a toothbrush or floss. It creates a rough surface on the teeth that attracts even more plaque, making oral health problems progress faster.

Tartar Buildup

Tartar buildup is commonly seen along the gumline and between teeth. It often has a yellow or brown appearance and can contribute to gum disease, bad breath, and tooth decay.

Cleanings and Preventative Care

This is why professional cleanings with your dentist in Scottsdale are important. We use specialized instruments to safely remove tartar during routine visits. These cleanings help reset the mouth to a healthier baseline and prevent long term damage to the gums and bone.

In everyday conversations with patients, it helps to explain plaque as something they can manage daily, while tartar is what develops when plaque is missed. Both play a role in oral health, but prevention is largely in the patient’s hands.

Regular brushing, flossing, and scheduled cleanings with our dentist work together to control plaque before it turns into tartar. When patients understand this process, they are often more motivated to stay consistent with their oral care routine.
