New Numbing Method

This is the technique my dentist used when I got some teeth knocked out by a wake surf board last summer.

The laser and cream definitely worked for me, and I didn't need to have any type of injection for the procedure.  This advance in dental technology is making it so much easier for dentists everywhere to complete their work in a less painful way.  Making life better for the patient, this new technique is an amazing discovery.

Comparative Delivery; Book/Blog

Though both sources offer good insight into the dental community, the delivery of information through a published book offers much more credible information due to the authors exceeding advancement in the field.  The blog is from a dental student who offers answers to questions from various people online about dental school and what is to be expected.  The style of the blog is very informal, the author seems to have a good sense of humor and jokes around a bit whereas the book is formal, and straight forward. Both are well directed toward a purpose and audience in that it is clear that the blog is for students coming into the field whereas the book covers the field in a broader and more general approach.
