The American Dental Hygiene Association has designated October as National Dental Hygiene Month. Good dental hygiene is the best weapon against your mouth’s number one enemy: dental plaque.
Plaque, a sticky biofilm that forms on your teeth, is an accumulation of bacteria, other microorganisms, food debris, and other unpleasant components. It can make your teeth feel fuzzy or slimy. And worse, the bacteria in plaque can lead to tooth decay and gum disease.
The best way to keep plaque at bay is by brushing your teeth twice a day and flossing once a day. But even though you can remove much of the plaque in your mouth with a toothbrush and dental floss, there are nooks and crannies that are hard to access with these basic oral hygiene tools.
Staying on top of dental plaque is an ongoing challenge. Immediately after teeth are cleaned, plaque starts to form again. And the longer plaque stays on teeth, the thicker it grows. Minerals in saliva become incorporated into the biofilm. As plaque takes on more minerals, it becomes calcified. This is when it hardens into calculus, or tartar. At this stage, tooth-brushing and flossing cannot disrupt the hardened layer of buildup, sometimes visible as yellow or brown deposits around the gum line.
This is why it’s important to schedule regular professional dental cleanings. At the dental office, we have special tools to remove tartar and get at those hard-to-reach places that your toothbrush and floss may have missed. If you have questions about dental hygiene, plaque control or another oral health issue, we are happy to talk with you. We are your partners in fighting plaque for a bright, healthy smile!

Saliva probably doesn’t rate high on your amazement meter. You’re more likely to notice its absence and the dry irritation that results.
But you might be more impressed with this unsung bodily fluid if you knew all the things it does. It’s definitely a multi-tasker, performing a number of jobs (including aiding in digestion) that not only keep your oral health on track, but your general well-being too. And there are even new testing methods where saliva may even tell us when you’re not doing so well.
Here are 3 more tasks your saliva is doing for your mouth right now that truly makes it amazing.
Cleansing. Your teeth’s chewing action shreds food so it’s easier to digest. But that also leaves behind tiny particles in your mouth. Bacteria feast on these particles (especially carbohydrates like sugar) and produce acid as a byproduct, which can increase your risk of tooth decay. Saliva serves as a kind of “rinse cycle” for your mouth, helping to wash a good bit of these errant particles down your throat and away from hungry bacteria.
Defense. Speaking of bacteria, your mouth is home to millions of them. While most are harmless or even beneficial, a fraction can harm your teeth and gums. Saliva is your first line of defense, emitting an antibody known as Immunoglobulin A that targets these bacteria. Saliva also produces an antibacterial substance called lyzozyme that prevents bacteria from growing.
Enamel Protection. Although it’s the strongest substance in the body, your teeth’s enamel can’t withstand the effects of mouth acid, the by-product of bacterial feeding and growth. Acid levels naturally rise after eating; but even this sudden rise can begin the process of demineralization where minerals in enamel dissolve. Saliva saves the day by first neutralizing the acid and restoring the mouth’s normal pH in about thirty minutes to an hour. It also helps restore minerals in enamel, a process called remineralization. It’s all in a day’s work for this remarkable fluid.
