Head and neck cancer use mouthwash more than toothpaste?

Use both: It is extremely important to keep your mouth healthy during cancer treatment. You should brush 3 times a day floss 2 times a day and ask your dentist for a flouride gel or mouthwash with flouride in it. Act rinse or the generic equivalent is in drug stores over the counter.

BOTH!: Stay away from alcohol-based mouthwashes. Alcohol is a drying agent, & will work with the radiation therapy to dry mouth out even more. Act Fluoride mouthwash is great. Also dry mouth rinses like biotene is amazing to help create saliva. Salivart spray is also otc that can be ordered from your pharmacist to help get rid of dry mouth. Caphasol has to be prescribed by your dentist; also great!

Both: If you are in treatment of head and neck cancer Fluoride is very important to ward off decay. Hopefully custom trays were made for you to hold Fluoride gel against your teeth. They should be used daily.
