Can a dental hygienist do anything else?

Dental hygienists also take  dental x-rays. The dentist will use these to help diagnose problems and decide on the possible treatment. Dental hygienists can also place fissure sealants, apply fluoride varnishes and administer fluoride treatments. Other procedures may be carried out by dental hygienists depending on the laws that apply where they work.

Tooth whitening is also often carried out by the dental hygienist, under a prescription from your dentist.
