I've been very happy with checkup/cleaning service for years until the last visit. The same hygienist, but it seems over time, she doesn't do the work as detailed as before. I could not the polishing process was not 100% covering all the teeth. The flossing is done for just one side. Not sure if she forgot or become careless after years of experiences. She did a careful/detail job before when she just got out of school. Btw, the dentist is doing a good job though.
