DappSmile making my gums feel weird after use?

I got that tingly feeling too the first couple times, but it faded once I stopped hovering right at the gumline so much. Mine actually feels fine now that I just do a quick pass and move on, so you’re probably onto something with the pressure thing.

A tingly feeling for an hour is pretty mild, so I’d just try shorter passes on soft mode. I usually do about 10 seconds per spot and that’s been fine.

The tingly thing has less to do with pressure for me than with how long I linger in one spot. I tried it on my lower front teeth where I get coffee stains and stayed on each tooth for a good while, then my gums felt buzzy for maybe an hour. Next time I did quicker passes and the feeling was way shorter. So I’d say it’s more about contact time than how hard you press. I’m still on the fence about whether it’s worth the fuss though, since it does knock off surface stuff but the whole buzzy gum thing is mildly annoying. Curious whether yours is mostly the front teeth or the back ones too, since that changes how awkward it is to keep the tip moving.

The mirror thing probably explains a lot of it. I catch myself doing the same, slowing way down on the front because I can actually see what I’m doing, then rushing the back. So I’ve been trying to just keep the tip moving even when I want to stare at a stain, since stopping to look is basically the same as lingering. Still annoying enough that I only reach for it every few days.

Mine does the same thing on soft mode, usually fades by the time I finish my coffee. I still use it a few times a week and the tingle has gotten less noticeable the longer I’ve had it. Could just be your gums getting used to the vibration.

I had a similar thing happen with a different brand of these ultrasonic cleaners, and mine was definitely from holding it in one spot too long without realizing it. I was basically parked on one tooth trying to get a stain off and by the time I was done the gum around it felt all buzzy and weird. Not sore, just that odd tingly feeling you described. What actually helped me was setting a mental timer, like moving along after a few seconds no matter how tempting it was to keep going on the same spot. Also I stopped using it right before bed because I noticed the weird feeling was more noticeable when I was just lying there thinking about it. If I were you I’d back off the gumline for a week and see if it goes away, then slowly bring it back. If it’s still happening after that, then maybe it’s the tool itself and not your technique. My sister had hers checked by a dentist because of similar gum irritation and they told her she was just going too hard near the edges. Not saying that’s your case, just that it seems to be a common thing with these tools in general.

The tingly thing for an hour seems long compared to what I’d expect from a quick pass. Mine fades in minutes, but I only run it along the front teeth where I can see the stains. Gums are pretty forgiving there.

Mine feels fine on soft but I keep it moving, never parked in one spot.
