Tartar... how does it form even if you brush your teeth every day?

"Tartar... how does it form even if you brush your teeth every day?"
Many people wonder why they still have "tartar (calculus)" even though they thoroughly brush their teeth.

The truth is... tartar doesn't just appear from sudden dirtiness; it is caused by "accumulated bacterial plaque."

When brushing isn't thorough enough, this soft plaque gradually hardens and calcifies into tartar, which can no longer be removed by regular brushing.

As it continues to build up, it can lead to:

• Gum inflammation (Gingivitis)
• Bad breath
• Receding gums
