Surprising Facts You Didn’t Know About Your Teeth and Dental Health

From the moment we wake up to the time we go to bed, our teeth quietly serve us. They allow us to enjoy our favorite meals, communicate with loved ones, and express ourselves with a smile. 

However, we often overlook how important they are for our health and how much we still have to learn about them. Understanding more about our teeth through surprising and important facts can guide us in better caring for them with the help of our dentist in Elizabethton, TN. 


The Structure and Composition of Teeth 

Teeth play crucial roles in our daily lives, enabling functions like chewing, speaking, and preserving facial structure. Each tooth is a complex structure made up of three main layers: enamel, dentin, and pulp. 

Surprising Facts about Tooth Composition 

  • Enamel is the Hardest Substance in the Body: Enamel, the outermost layer of teeth, is exceptionally durable, protecting against wear and tear.
  • Teeth Are Not Just White: Despite common perception, teeth come in various shades. They vary in color from person to person, influenced by factors such as genetics, diet, and lifestyle habits.
  • Teeth Have Their Own Blood Supply: Despite their solid appearance, teeth are living tissues. The pulp within each tooth houses blood vessels and nerves, ensuring sensitivity and nourishment.

Dental Health and Overall Health 

The connection between dental health and systemic health is profound and multifaceted. Good dental health is essential for maintaining a healthy mouth and has far-reaching implications for overall well-being. 

Facts About the Impact of Dental Health on Overall Health 
  • Links Between Gum Disease and Heart Disease: The inflammation caused by gum disease may contribute to the development of cardiovascular problems such as heart attacks and strokes.
  • Dental Health's Role in Diabetes Management: People with diabetes are more susceptible to gum disease, and untreated gum disease can make it harder to control blood sugar levels. Conversely, managing gum disease can help improve diabetic control.
  • Gum Disease Can Contribute to Respiratory Problems: Bacteria from the mouth can be aspirated into the lungs, leading to respiratory infections such as pneumonia. People with poor dental health, especially those with gum disease, may be at higher risk of developing respiratory problems.

Tooth Decay and Cavities 

Tooth decay is a common oral health problem. It occurs when bacteria in the mouth feed on sugars from food and produce acids that erode the enamel, forming small holes (cavities) in the teeth. 

Important Facts About Cavities and Tooth Decay 
  • Cavities Are One of the Most Common Chronic Diseases: Tooth decay is incredibly prevalent, with the World Health Organization (WHO) estimating that it affects nearly 60-90% of school-aged children and the majority of adults worldwide.  
  • Tooth Decay Can Be Contagious: While cavities themselves are not contagious, the bacteria responsible for causing cavities can be transmitted from person to person through activities like sharing utensils, kissing, or even blowing on food.  
  • Cavities Don’t Only Develop on the Chewing Surfaces: While cavities are commonly associated with the chewing surfaces of teeth, they can also develop in other areas, including between teeth and along the gumline.  

Oral Hygiene Practices 

Good oral hygiene helps us maintain healthy teeth and gums. It involves regular brushing, flossing, and mouthwash to remove plaque, bacteria, and food particles from the mouth. These habits help prevent tooth decay, gum disease, and other oral health problems. 

Important Facts About Oral Hygiene Practices 
  • Most People Don't Brush Their Teeth Long Enough: Studies have shown that the average brushing time is only about 45 to 70 seconds, which may not be sufficient to effectively remove plaque and bacteria from all tooth surfaces.
  • The Order of Brushing and Flossing Matters: Flossing before brushing helps remove food particles and plaque from between teeth, allowing toothpaste to reach more surfaces and provide better protection against cavities and gum disease.
  • Mouthwash Containing Alcohol Can Be Detrimental: While mouthwash can be beneficial, those containing alcohol may have drawbacks. Alcohol can dry out the mouth, reducing saliva production and potentially leading to dry mouth and even bad breath.

Genetics and Dental Health 

Genetics can significantly influence various aspects of dental health, including tooth development, susceptibility to oral diseases, and the structure of teeth and gums. 

Facts About Genetics and Dental Health 
  • Genetics Influences Tooth Alignment and Spacing: The arrangement and spacing of teeth are partly determined by genetics. Some people may inherit traits predisposing them to crowded or misaligned teeth that require orthodontic treatment to correct.
  • Some People Are Predisposed to Gum Disease: Certain genetic variations can increase the risk of developing gum disease (periodontitis). People with a family history of gum disease may be more susceptible, even with diligent oral hygiene habits.
  • Genetic Factors Can Affect Enamel Strength: The strength and durability of tooth enamel can be influenced by genetic factors. Some people may inherit genes that result in weaker enamel, making their teeth more prone to decay and damage.

Aging and Dental Health 

As people age, they may experience various dental health concerns due to natural wear and tear, changes in oral health habits, and underlying health conditions. 

Facts About Aging and Dental Health 
  • Tooth Loss Is Not an Inevitable Part of Aging: While tooth loss is more common among older adults, it is not an unavoidable consequence of aging. Many older adults can maintain their natural teeth well into old age with proper dental care and preventive measures.
  • The Nerves in Teeth Can Shrink: As people age, the nerves inside teeth may shrink, leading to decreased sensitivity to pain and other sensations. This can make it more challenging to detect dental problems.
  • Medications Can Contribute to Dry Mouth: Many medications commonly used by older adults, such as those for high blood pressure, allergies, and depression, can cause dry mouth as a side effect.
