I learned about oral irrigators after having my wisdom teeth extracted. I was wondering what to do about the food particles stuck in the crevices, as flossing and a toothbrush weren't enough, when a friend recommended one. Whenever I want to clean tight spaces or between my gums, I use the water pressure to spray the water, and it removes the debris effectively; I even found things I couldn't see before. I like that I can manually adjust the water pressure. If you are getting wisdom teeth extracted or have gaps between your teeth, I think it would be a good idea to have an oral irrigator on hand.🙂
