Plaque vs. Calculus: Difference and Comparison

By Muazma Batool & Muneeza Rehman — Published on March 14, 2024

Plaque is a sticky, colorless film of bacteria that forms on teeth, leading to dental issues if not removed, while calculus, or tartar, is hardened plaque that has mineralized on the teeth and requires professional removal.

Plaque vs. Calculus

Difference Between Plaque and Calculus

Dental plaque is a soft, sticky film that accumulates on the surfaces of teeth. It consists of bacteria, microbial substances, and food debris. Regular brushing and flossing can effectively remove plaque, preventing tooth decay and gum disease. Calculus, known as tartar, is what plaque becomes when left untreated. It hardens on the teeth due to the mineral content in saliva, creating a rough surface that can lead to further plaque accumulation and gum irritation.

The formation of plaque is a continuous process and can begin to reform on the teeth just hours after brushing. Its soft nature allows for easy removal with good oral hygiene practices. Calculus, on the other hand, cannot be removed with a toothbrush or floss; it requires professional dental cleaning. This distinction highlights the importance of regular dental care to prevent plaque from advancing to calculus.

Plaque's presence is primarily indicated by its soft, sticky texture and is virtually invisible. It can lead to cavities, gum disease, and bad breath if not regularly cleaned. Calculus has a harder texture and can be visibly identified as a yellow or brown deposit on the teeth. Its rough surface provides an ideal environment for additional plaque buildup, exacerbating dental problems.

Preventing plaque buildup is key to avoiding calculus formation. Good oral hygiene practices, including brushing twice a day, flossing daily, and using an antiseptic mouthwash, can significantly reduce plaque levels. Once plaque has hardened into calculus, only a dentist or dental hygienist can remove it, typically through scaling and polishing, emphasizing the need for regular dental check-ups.

Both plaque and calculus contribute to the development of periodontal diseases but at different stages and severities. While plaque can be managed with routine home care, calculus formation signifies a progressed state of neglect, requiring professional intervention to prevent further dental damage and restore oral health.
