Is Dental Hygiene Cleaning Good?

Our university has this dental clinique that as we have paid our insurance they charge us like $10 now for dental cleaning. They told us that only Flouride process is not included. I am afraid that my tooth get more sensitive after cleaning.

Does it make make the tooth more sensitive? and is it required really to remove the plaques and cavities from tooth?

Suggestion:

If you want to keep your teeth, dental cleanings are absolutely necessary.
If you haven't had a teeth cleaning in a few years, then there may be a lot of tatar buildup (hardened plaque). If there is a lot of buildup under the gums, then yes it can be a little sensitive. But if you dont have your teeth cleaned and the tartar just stays there, it will buildup more and more and you will get whats called gum disease. This causes the gums to be inflamed and recede and even bone loss, and will result in tooth loss, but this happens over years.

Having a cleaning will remove the buildup and plaque, which is required if you dont want cavities and gum disease. And if cavities are left untreated they will just become bigger and reach the nerve of the tooth and then you will need a root canal. These major problems can be avoided with regular cleanings. And dont forget to always take care of your teeth at home inbetween cleanings. Brush and floss.
