Tar is not the correct term used in dentistry. The substance you're likely referring to is tartar, also known as dental calculus.
What is Tartar?
Tartar is hardened dental plaque. Plaque is a sticky film that constantly forms on your teeth. It's made up of bacteria, food particles, and saliva. If plaque isn't removed through regular brushing and flossing, it hardens into tartar. This hardened substance is a leading cause of gum disease.
Unlike plaque, tartar can't be removed by brushing and flossing at home. It must be professionally removed by a dentist or hygienist during a dental cleaning. Tartar is typically yellow or brown and can form both above and below the gum line.
Causes of Tartar Buildup
Tartar formation is primarily due to a failure to remove plaque through proper oral hygiene. Acid-forming bacteria within plaque contribute to tartar buildup and can damage tooth enamel, leading to cavities. The longer plaque remains on teeth, the greater the likelihood of it hardening into tartar.
Preventing Tartar Buildup
- Regular Brushing: Brush your teeth twice a day for at least two minutes each time using fluoride toothpaste and a soft-bristled toothbrush.
- Daily Flossing: Floss daily to remove plaque from between your teeth and below the gum line where your toothbrush can't reach.
- Regular Dental Checkups: Visit your dentist for professional cleanings and checkups at least twice a year. These cleanings remove tartar and plaque that you can't remove yourself.
Key Differences Between Plaque and Tartar
| Feature | Plaque | Tartar (Dental Calculus) |
|---|---|---|
| Consistency | Soft, sticky | Hard, calcified |
| Removal | Can be removed by brushing & flossing | Requires professional cleaning |
| Color | Usually colorless or whitish | Yellowish or brownish |
| Health Impact | Can lead to cavities and gum disease | Leading cause of gum disease |
