My dental hygienist recommended the Philips SonicCare 9000 model. All the tech numbers are there to read so I won't get into them. Being diabetic my saliva carries excess sugar. Also, having acid reflux is another possible reason that could affect the health of my teeth and gums. So I purchased the 9000 model. I got lucky and got it on sale. $125 instead of $250.

This was workable, but sudde Troy · samsclub.com
