Cardiovascular Health

One of the strongest links between oral health and overall well-being involves cardiovascular health. Poor oral hygiene allows bacteria to thrive in the mouth, which can then lead to gum disease. Harmful bacteria also has the potential to enter your bloodstream through damaged or inflamed gums, which can then create plaque in your arteries. As this plaque builds up, the risk of cardiovascular events, such as heart attacks or strokes, increases.¹

Diabetes

Diabetes can lead to oral health issues, which can make management of the disease more challenging. High sugar levels are found not only in blood, but also saliva, which can lead to increased susceptibility to gum disease. Gum infections can make it harder to control blood sugar levels, creating a vicious cycle. Good oral hygiene is essential for diabetes management.³

Respiratory Health

Oral health can also affect respiratory health. Poor oral hygiene can lead to bacterial infections in the mouth, which may be inhaled into the lungs, causing inflammation and infection. Gum disease and tooth decay can worsen respiratory conditions like asthma and chronic obstructive pulmonary disease (COPD).⁴ Daily oral hygiene can help not only your teeth, but also your lungs by removing bacteria before it can spread to your lungs.

Mental Health

Unmet dental problems can cause a decline in mental health. Toothaches, gum pain, and missing teeth can lead to feelings of self-consciousness, low self-esteem, and even depression. Conversely, when mental health suffers, so can oral health. Poor mental health can make it difficult for individuals to keep up with proper oral hygiene habits.⁵ This creates a continuous cycle, where worsening oral health further deteriorates mental well-being.

Pregnancy

Oral health is especially important during pregnancy. Bacteria buildup can be passed along to a developing baby and serious gum disease has been linked to increased risk of preterm delivery.⁶ Poor oral health are common during pregnancy as hormonal changes boost the risk of developing gum disease, stomach acid from morning sickness can weaken teeth, and frequent snacking can lead to increased production of bacteria in the mouth. Maintaining good oral hygiene habits and regular dental check-ups are vital to the health of both mom and baby.

A good oral hygiene routine includes brushing and flossing at least twice a day and seeing a dentist at least every six months for an evaluation and cleaning. Routine check-ups can help identify and address issues before they become serious.  A dental plan can help save you money on out-of-pocket costs for preventive visits and cleanings.
