Don't Forget the Distal: Why Cleaning Your Back Tooth Surfaces Matters

Maintaining strong, healthy teeth requires a comprehensive oral hygiene routine that addresses every part of your mouth, including the often-neglected distal surfaces of your teeth. These are the surfaces furthest away from the median line of your face, particularly prevalent at the back of your mouth. Failing to properly clean these areas can have significant consequences for your oral health. The American Dental Association defines the distal tooth surface as the "surface or position of a tooth most distant from the median line of the arch." This median line runs vertically down the center of your face, between your two front teeth. Therefore, any tooth surface moving away from this central line is considered distal. To effectively keep these distal surfaces clean, a good oral care routine is paramount. This routine should include brushing all your teeth twice daily and thoroughly cleaning between all your teeth once a day using floss, a water flosser, or another interdental device. Many individuals find it challenging to reach the distal surfaces, especially those on the molars at the very back of the mouth. If you struggle with this, your dentist or dental hygienist can provide valuable tips and strategies to improve your reach and technique. If traditional string floss proves difficult to maneuver, consider alternative flossing methods. Water flossers, for example, offer a steady stream of water that effectively dislodges plaque and food particles from between your teeth. The key is consistent and correct use of any interdental cleaner to ensure all surfaces are addressed. Neglecting the distal tooth surfaces can lead to unfortunate consequences, primarily tooth decay. Your teeth are constantly covered in a sticky film called dental plaque, which contains bacteria. These bacteria produce acids when they interact with sugars from your diet. Repeated acid attacks can erode tooth enamel, leading to dental caries, commonly known as cavities. Daily removal of plaque through brushing every tooth surface is crucial. Furthermore, plaque buildup can also contribute to the development of gum disease, highlighting the importance of interdental cleaning. The distal surfaces, despite being hard to reach, are particularly vulnerable to plaque and food accumulation. Research, such as a report in Dental Anatomy, indicates that impacted third molars often lead to plaque buildup against the distal surfaces of second molars, which can result in specific decay known as distal cervical caries. In conclusion, your oral care routine must encompass every tooth and every tooth surface. Do not overlook the distal surfaces, especially those located at the very back of your mouth. If you encounter difficulties reaching these areas, consult your dentist or dental hygienist for assistance. With their guidance, you can maintain a consistently bright and healthy smile.
