I rarely look at my teeth when I brush them. I noticed a weird rough surface at the back of my bottom-row teeth. So I inspected my lower teeth with a small mirror I could fit inside my mouth. I had a ton of calculus (tartar) build up. No matter how hard I brushed or used my nails to scratch, I couldnt get it off. It was annoying!I bought this item because I saw great reviews on it. Boy, I tell ya. Im glad I did. Its very sharp! I went online to read on how to scale. In matters of hours of reading and learning, I was scaling away at my teeth. I was amazed how effective it was in removing those tartar build up. I had spent a good 2 hours on my teeth with this scaler, and now my teeth looks BRAND NEW. I usually dont get too excited about putting sharp objects in my mouth, but this tool is really worth it. It will also help if you are going to whiten your teeth, which Im currently in the process of doing.Pros:Sharp and effectiveTwo different tips for scalingMaterial is sturdy and well-made.Gives you the temperature of sterilizationMade in Korea (not China) hahahaCons:If you dont have good eye-hand coordination, you might end up tearing up your whole mouthThe tips are huge. Personally, I thought they could have made it smaller.Doesnt come with instructions on how to useDoesnt give you a carrying pouch or container for this sharp toolNot made in Japan (Not really a con, but I thought it was funny to add)  Read Less
