Hi, Seth,

My husband has been using the Sonicare toothbrush for about a year. Like a lot of people, he can't open his mouth as much as he could pre cancer. Before he started using Sonicare, his gums were receding--we think from radiation. His teeth also became very sensitive. His dentist treated his teeth on a few visits with a gel to control the discomfort and then he applied a bonding agent to cover the exposed roots. That helped a lot. The Sonicare toothbrush is great for getting his teeth clean and getting into his mouth where a regular tooth brush is too big. His mouth is still sensitive (not the teeth) so I know he is very careful about being gentle.

Good luck--
Anita
