I sat through a cleaning last year where the hygienist said "four" three separate times, and each "four" felt like a tiny verdict. My teeth looked fine in the mirror. They didn't hurt. So why was she poking at my gums and reading numbers off like a referee?
Turns out the numbers matter more than most of us realize. When you visit a richmond centre dentist, those little measurements, the probing depths, tell a story about your gum tissue that your teeth can't. And that story gets checked at every cleaning for a reason.
Here's the short version: your gums are the foundation your teeth sit in. If the foundation shifts, the teeth follow. This piece walks through what those numbers mean, why the questions keep coming, and the small habits that move the needle.
What those numbers mean
Your hygienist calls out numbers, usually between one and seven, for each tooth. Those are millimeters of space between the gum and the tooth. One, two, or three is normal. Four is a warning sign, and anything higher suggests the gum has started to pull away from the tooth.
That gap has a name: a pocket. A shallow pocket is easy to clean. A deep one is a hiding spot for bacteria, and your toothbrush can't reach the bottom of it no matter how long you brush. This is why the American Dental Association ties those pocket measurements directly to diagnosis and treatment planning.
Most adults walk around with at least a few fours. According to the Centers for Disease Control and Prevention, gum disease is common among adults in the United States, which means you're likely not alone if your hygienist is calling out fours. The stat itself isn't the point. The pattern is. Three fours that stay three fours for years is different from the same three creeping up to fives and sixes.
Why your dentist keeps circling back to the same question
The recurring question isn't really "are you flossing?" It's "is anything changing?" Dentists track pocket depths over time the way a mechanic tracks your mileage. A single reading means little. A trend means everything.
If your readings stay flat, great. If they creep up, that's a signal worth acting on before the tissue does more damage. And once pockets deepen enough, the tissue and bone that hold your teeth in place can start to lose their grip. The National Institute of Dental and Craniofacial Research explains how the infection involved in gum disease can affect the surrounding bone, which is why the checkup looks the same every time: watch the numbers, watch the trend.
Here's the part I wish I'd internalized earlier: your dentist isn't judging you. They're watching a slow-moving graph, and you're the only person who can change its direction between visits.
A simple framework: the Three-Month Rule
One thing that changed how I think about my own routine is a simple framework I'll call the Three-Month Rule. The idea: any change to your brushing, flossing, or cleaning routine gets a full three months before you judge whether it's working. That's roughly the window between cleanings, and it's enough time for pocket depths to start reflecting your habits.
Three months is also a practical test of a routine. If you can keep it up for that long, it probably survives past the honeymoon phase. If you can't, the routine was the problem, not your willpower.
So instead of "did I floss every day this week," ask yourself "did I do it four or five days most weeks this quarter?" That reframe kills the guilt and gives you something measurable to compare against your next set of readings.
The habits that move your readings
I'd skip the long lists floating around and focus on these four, all of which are boring and all of which work:
Brush the gumline, not just the teeth. Angle the brush toward where the tooth meets the gum and let it sit there for a moment. That's the spot most people skip.
Use interdental brushes if floss keeps slipping. The tiny brushes reach where floss struggles, and they're faster. Ask your hygienist what size fits your gaps.
Get a cleaning on schedule, not when it's convenient. Routine cleanings remove what brushing can't. Skipping them resets nothing and lets buildup keep building.
Say something if something bleeds. Bleeding gums during brushing is a live signal. Tell your dentist and let them look at it.
None of this requires a fancy gadget. The electric brush is nice, but a plain soft brush used with care will do more than a pricey one waved around absentmindedly.
What to ask at your next appointment
You don't need a script to make the visit more useful, but a few specific questions go a long way. Ask which readings changed since your last visit and why. Ask whether any of your pockets have deepened enough to warrant extra attention. Ask what one habit would give you the most benefit if you kept it. Most dentists will answer all three in under two minutes.
If your gum readings are moving in the wrong direction, you've got options beyond "floss more," from deep cleaning procedures that target the pockets directly to more frequent check-ins. The point of the questions isn't to fix everything in one visit. It's to catch the trend early enough to steer it. The best time to care about your gum numbers is when they're still small and boring, right before they become interesting for all the wrong reasons.
Book the appointment you've been putting off, then say out loud that you want to understand your numbers. It's a short conversation, and it changes what you do at the sink every morning.
