There are so many options for toothbrushes when you go to the store, it can be quite confusing. I’ve been a hygienist for a long time now, and I can tell you that as soon as my patient opens his mouth, I know immediately if they own an electric toothbrush or a manual one. There are so many brushes on the market to look at that makes it difficult to choose.
First of all, the brush should be rechargeable (NOT a battery operated one). The best brushes are either the Oral B or Phillips Sonicare. They have both been available for a long time, so that they have been tested and proven to give long term results. Once you have purchased one, it will last for a long time. The brushes are of good quality and reasonable in cost.
My personal preference is the Sonicare Diamond Cleaner. I have found it to be gentle on the gums and light to hold. My patients have spoken very positively about it, which means they are using it. If you find a system you like, you will always have better results. This is also a great travel toothbrush since it is USB rechargeable. That is very important if travel is a large part of your work.
