Distance learning, also called online education, is very attractive to students, especially who want to continue education and work in field. At University of Pittsburgh-Bradford, 4 students are enrolled exclusively in online cources and 469 students are enrolled in some online courses based on 2015-2016 enrollment data.
Home Remedies for Whiter Teeth. Some people still prefer the age-old home remedy of baking soda and a toothbrush to gently whiten teeth at home. Also, some foods such as celery, apples, pears, and carrots trigger lots of saliva, which helps wash away food debris on your teeth.
In-office whitening or professional whitening is the most predictable and effective way to whiten your teeth when followed by an at-home whitener for 7-14 days. The whitening results in the office need to be stabilized by a high frequency at-home technique where the real whitening takes place.
