I brushed my teeth "correctly" for 28 years and a dentist just told me I've been doing it wrong the entire time. My gums are ruined.
For nearly three decades I have been brushing my teeth the way I was shown as a kid: hard, fast, side to side, two minutes, done. I thought I was doing great. I floss. I use mouthwash. I even use one of those expensive electric toothbrushes I saw a dentist recommend on a video. I genuinely believed my mouth hygiene was above average.
I went in for a routine cleaning last week and the hygienist got very quiet while she was doing the initial check. Then she called the dentist over. They were both poking around and using words like "recession" and "wear pattern" and I started to get that sinking feeling.
Turns out I have been brushing way too hard and at completely the wrong angle for my entire life. You are supposed to hold the brush at a 45 degree angle toward the gumline and use tiny circular strokes with almost no pressure at all. I was essentially taking a wire brush to my enamel and gums twice a day every single day since I was old enough to reach the sink. The damage to the gum tissue at several teeth is permanent. It does not grow back. I have visibly receding gums at 28 years old and I caused it myself by trying to be clean.
The thing that is making me spiral is that I was never doing nothing. I was actively brushing. I thought I was being diligent. This whole time the effort I was putting in was literally making things worse and I had no idea because nobody ever corrected me after I was about seven years old.
I looked it up when I got home and apparently this is extremely common. Toothbrush abrasion is one of the most frequently seen issues in dental offices and most people have no idea they are doing it. You want to see almost no white on your bristles after two minutes because that means you barely pressed. If your bristles splay out like a fan after a month you are brushing way too hard.
Please go look up the modified Bass technique right now. Watch one video. It took me about three minutes to realize everything I knew was wrong. I wish someone had told me this when I was a teenager instead of just telling me to brush more.
