I am a retired dentist and no longer had access to the ultrasonic scalers in my office and didn't want to spend $500-$1500 for a professional system. This is very well-made. It's vibration is quite adequate to remove calculus (tartar). Used properly it should not hurt at all. If it were more powerful it would require running water for cooling (like a jet pointed at the tip).
I wish I would have taken before and after pictures because explaining does nothing. For the amount of stains I had on my top and bottom teeth I was so embarrassed, I’d cover my mouth when I talk and wouldn’t smile with my teeth. I’m only 24 and bad habits like smoking/drinking coffee will really do damage. I seen this and wasn’t very hopeful with it being so cheap but I figured I’d just give it a try. It came last night and I decided to try it, IMMEDIATELY IT ALL STARTED TO COME OFF. My teeth are white again and I’ve never been so pleased! It doesn’t hurt and it’s just overall the best thing I’ve done. Highly recommend this even for terrible stains because trust me I had them.
This product is wonderful. I was able to remove some pesky stain in the crevices near my gums. I floss daily, and use a teeth whitener at home. However, I could never quite remove the stains that have built up in between my teeth in those hard to reach places. Using this product for the first time, the stains came off after about 5 minutes of scaling. I would suggest that you watch a few youtube videos on how to do it property, since it can damage your gums if you are not familiar with the technique.
I love this thing. I started using it on the highest setting right away and it was instantly easy to use. It'd be very hard to hurt yourself with this unless you were using it very wrecklessly. Easy to use, quick to learn. ACTUALLY works. You can see calculus/tartar 'shaving' off while you're using it. Zero pain or sensitivity. Feels like solid construction, no cheap feel. No, it will not instantly remove major stains, stay consistent and it eventually will Definitely worth your purchase.
I used this calculus scraper and it cleared most of my plaque. ive never used one of these before but i got the idea to search for a consumer version after a $100 dental visit for teeth cleaning/plaque removal which the dentist said i need to come back every 6 months to do. a steady-ish hand and light application is all you need with this tool to save loads of money at the dentist. i gave it 5 stars because it is very effective when compared to dentist bills. i did it myself. i imagine you can get even better results if you can get someone to do it for you with care. very happy with this purchase!!
