Dental Hygiene is Important

Regular teeth cleanings are a staple of dental care. Dental Hygienists specialize in preventative oral health care. They thoroughly clean a patient’s gums (periodontium) around the teeth, and they can offer helpful information on how to properly take care of your teeth at home. Routine cleanings along with proper oral home care can prevent gum disease. The initial signs of gum disease include swollen gums that bleed due to chronic bacteria and plaque. If gum disease is left untreated, it can lead to bone loss and potentially tooth loss. According to the American Dental Association (ADA) about 3 in 4 adults over 35 have some form of gum disease. It is one of the major causes of tooth loss in the US.


Your periodontal (gum) health can impact your overall health. Gum disease has been shown to be linked with ailments such as heart disease, stroke, diabetes, pre-term births, osteoporosis, and upper respiratory infections. With proper and routine oral care, you can significantly reduce your risk of these potentially serious problems. Additionally, a healthy mouth can improve your appearance and confidence.
