Ultrasonic Toothbrushes and Oral Hygiene



I am using a SoniCare ultrasonic toothbrush tester that my dentist gave me for a trial run. It has a built-in timer that alerts me every 30 seconds to shift arches and it shuts off after 2 minutes. I think it is cleaning my non-bite surfaces, but my mouth doesn`t feel as fresh as when I was brushing with a manual toothbrush. Is this something I should be concerned about? Also, my bite surfaces aren`t getting as much attention with the sonic toothbrush as with the manual toothbrush. How much is enough? One of my teeth seems to be more sensitive to cold drinks since I`ve started using this device. Could I be causing my fillings to crack by using the ultrasonic toothbrush? Thanks for your help.


The Sonicare is a good brush to use. If you are having trouble using the brush, take it to your dentist and have him/her watch you use it so you cannot hurt yourself. Using the brush will not cause cracks in the teeth. You may be using too much pressure against the tooth.
