Between “old wives’ tales” and “conventional wisdom” there can be quite a few bits of misinformation floating around. The topic of teeth and what can affect their health is no exception. Check out these bits from http://www.dentalassistingschool.org/:
Are Baby Teeth Important?
Wrong Answer: Since they are just going to fall out anyway, why bother?
Right Answer: Because tooth neglect at any age can lead to serious health problems, baby teeth should be treated with the same care as adult teeth. In addition, baby teeth that have been neglected can fall out sooner, resulting in crooked or malformed adult teeth.
When Should You be Concerned about Wisdom Teeth?
Wrong Answer: Leave wisdom teeth in until they bother you.
Right Answer: Once a wisdom tooth has become impacted, or misaligned, it can lead to serious problems such as infection or periodontitis. A good rule to remember is to get them removed earlier, as the procedure is easier and comes with less complications. If unsure about how to proceed, have your dentist take X-rays.
