Considering that's such an individualized question it would be best answered by your dentist or dental hygientist considering the health of everyone's teeth and mouth is so different.
My dentist told me not to use those toothpastes because they can make me sensitive and it you get too aggressive, you can wear down the enamel but they might be suitable for others.
BTW...I just stumbled across the $90 Sonicare Essence Toothbrush on sale now at Drugstore.com for $57.99! I placed the link below so you can read the reviews and check out the model type, etc.
It seems like once you use sonic technology for the deep cleansing it provides for both your teeth (Sonicare) as well as your skin (Clarisonic) it's difficult to ever go back to normal or manual cleaning.
