Hi Ann,

My wife has the same problem.  She has had good luck using a waterpik water flosser wp-667w.  Here is a link      https://www.waterpik.com/oral-health/products/dental-water-flosser/WP-667/

Waterpik makes a bunch of different products and accessories for oral Hygiene.  I’m sure there are other companies out there with similar products.  This is the one that has worked will for us.

Hope this helps.
