Taking Dental Cleanings to the Next Level with Guided Biofilm Therapy

This fall has been a busy one here at Green City Dental, most importantly with the recent grand opening of O2dontics, our sister practice across the street! While Dr. Taylor focuses on TMJ therapy, airway health, and functional orthodontics over there, Dr. Isabel, Dr. Carroll, and our Green City team will continue to deliver comprehensive biological dentistry here in our original office – the preventive care, restorative work, and whole-body approach to oral health that’s always been at our core.

We’ve also just welcomed a new member to our hygiene team, Wendy, who we’ll be introducing to you in more depth in next month’s post. For now, we can say that we are so happy that she’s now a part of our crew, gently and skillfully providing preventive dental care to patients like you. We think you’ll like her, too.

When most people think of a dental cleaning, they think of the standard method of scraping away plaque and tartar with hand instruments and ultrasonic scalers. It’s a methodical process, and it works. Countless people have kept their teeth healthy this way. It’s just not exactly pleasant. There’s the scraping sensation and the high-pitched whine of the ultrasonic.

And because the hygienist can’t always see every plaque trouble spot, they can sometimes scale the teeth more aggressively than they need to. You do end up getting a thorough cleaning, just not the most comfortable one.

Guided biofilm therapies (GBT) are different because the hygienist starts by making the invisible visible with a disclosing solution that reveals every trace of biofilm – that sticky coat of bacteria and other microbes that builds up on your teeth through the day. When you can actually see where it’s lurking, the whole approach to cleaning changes.

Instead of guesswork, you get targeted, precise plaque and tartar removal.

It’s sort of like what you see when we look at samples of your saliva through our phase contrast microscope during your exams. Once you see all those critters dancing around, getting down in your mouth, you get a better understanding of how and why you need to step up your oral hygiene.

Once we can see the biofilm, we gently remove it with an air-polisher that combines warm water, air, and a very fine erythritol powder. The powder is low-abrasion and safe to use on natural teeth and dental work alike. There’s no scraping involved. There’s no uncomfortable vibration. There’s just a gentle stream that systematically removes biofilm and stains.

If there are still calculus (another name for tartar) deposits on the teeth, we remove it with an ultrasonic scaler – a process that’s typically much faster and gentler than traditional scaling since most of the biofilm has already been removed.

While guided biofilm therapies are a relatively new development, some research has already been done that shows how effective GBT can be. One of the most recent is a randomized controlled trial from last year in which GBT went head-to-head with traditional scaling.

Sixty people with periodontitis – advanced gum disease – participated, with each receiving GBT on one side of their mouth and traditional treatment on the other. Outcomes were measured right after treatment and again five months later. The research team tracked pocket depths, bleeding on probing, and treatment time.

In the end, both cleaning methods were found to be effective. Periodontal pockets were shallower, and overall gum health was better. But GBT took significantly less time to perform, and patients reported that it was far more comfortable.

And that’s something that can make your hygiene appointments a lot more relaxed, even something to look forward to, considering that regular exams and pro cleanings are a key part of preventive care, just like your brushing and flossing at home.

But hygiene isn’t just about what happens in the dental chair or at your bathroom sink. It’s about everything you do to support the health of your mouth.

That includes lifestyle factors most people don’t necessarily associate with dental care – things like your diet, how well you sleep, whether you’re managing stress, how much you move your body, and more. That’s because ultimately, oral hygiene includes anything you do that can affect the health of your teeth, gums, and other oral tissues – as diet, sleep, and so on do.

Of course, your hygienist is a key resource in all of this. She’s not just there to clean your teeth but help you understand what’s happening in your mouth and how to keep the oral environment as healthy and balanced as can be. Your hygienist can help you figure out which home hygiene approaches make the most sense for your situation and how to weave them into your daily routine.

Your regular hygiene appointments are where all of this comes together – the exam, the cleaning, the education, and the personalized guidance – so you can take full charge of your mouth-body health.
