Review (1/5): Leave the scaling to a professional
I give this product no stars. These are not professional dental instruments. As a dental hygienist for 35 years I’ve seen people injure their teeth and gums by scraping their teeth with instruments like these. You can cut your gums and scratch the enamel. Please just see your dental hygienist for professional cleanings twice a year. If you can’t afford it try hospital dental clinics or dental hygiene schools, they are always looking for patients, and you get a very thorough cleaning, x rays cancer screening for a very reasonable price, or free!
