What is Biofilm and How Do You Get Rid of It?

We talk about plaque a lot in dentistry—but what many patients don’t realize is that plaque is only the beginning. Behind the scenes, something more complex is forming on your teeth every day: biofilm. At Alma Dental Care in Petaluma, CA, Dr. Maria Serrano helps patients understand what biofilm is, why it matters, and how to stay ahead of it.

Biofilm: More Than Just Buildup

Biofilm is a thin, sticky layer of bacteria that clings to surfaces in your mouth—especially teeth and gums. Plaque, the soft film you feel along your gumline, is actually a type of biofilm. What makes biofilm different from loose food particles is its structure. The bacteria organize themselves in layers and protect each other, making it more resistant to basic brushing or rinsing. If left untouched, this living layer can harden into tartar and lead to gum inflammation, tooth decay, and even periodontal disease.

It’s not just about how it looks or feels. Biofilm plays an active role in causing cavities and gum disease. That’s why removing it regularly is so important.

How to Disrupt Biofilm at Home

Daily brushing and flossing are essential—not just to remove food particles but to physically break up biofilm before it hardens. Use a soft-bristled toothbrush and fluoride toothpaste, brushing for two minutes twice a day. Floss once a day to reach between teeth where biofilm loves to hide.

For patients who are more cavity-prone, Dr. Serrano may recommend professional fluoride treatments and dental sealants to strengthen enamel and reduce the risk of decay. A water flosser or an antimicrobial mouth rinse can also be helpful for disrupting biofilm and reducing bacteria between cleanings. These additions can give your daily routine an extra layer of protection.

Why Your Dental Visits Matter

Even with great home care, some biofilm will harden into tartar over time. That’s where professional dental cleanings come in. Hygienists use special instruments to remove buildup that brushing alone can’t touch. Regular cleanings help prevent gingivitis and keep your mouth healthier overall.
