A dental hygienist is someone who will be able to look after your general oral health, not just your teeth. They specialise in providing patients with help and advice, as well as a thorough clean. For example, your hygienist may be able to advise you on a different type of toothbrush to use, or a new way of flossing.
It is important to visit a hygienist as well as a dentist. Hygienist services are not always available on the NHS so you might have to pay privately. They will give your teeth a thorough clean, going up into the gums to make sure your mouth is well looked after. This also allows them to look for any issues, like bleeding gums or sore spots in your mouth.
You should visit a hygienist once every 6 months, to once every year. Floss between appointments on a daily basis to keep your teeth healthy.
