My husband had a couple of rinses for the sores - Stamford's #7 and a tetracycline based swish and spit. If your husband's personal dentist is not familiar with dealing with oral cancer survivors, his team at the hospital can probably make a referral.
My husband also had to take time off from the flouride trays.
Take care and best wishes to both of you!
