How Much of Your Teeth Are Situated Below the Gums?
Posted on 10/1/2025 by Lone Pine Dental |
 Think about the pearly whites you flash in a smile. Did you know that most of your teeth are actually hidden below the gum line?
It might seem surprising, but only about one-third of each tooth is visible – the part we brush and floss every day. The remaining two-thirds are embedded within the jawbone and gums, providing a secure anchor for chewing and biting. This hidden portion plays a critical role in oral health and overall well-being.
What Lies Beneath the Surface: Exploring the Subgingival Zone
Below the gum line, the tooth is covered by a specialized layer called the cementum. Unlike the visible enamel, which is hard and white, cementum is a softer, yellowish tissue that facilitates attachment to the periodontal ligament, a group of fibers that connect the tooth to the bone. This intricate connection allows for slight movement, providing a shock-absorbing mechanism during chewing. Additionally, the periodontal ligament houses blood vessels and nerves, supplying essential nutrients and sensation to the tooth.
The Importance of Subgingival Care: Prevention Dentistry in Action
While we diligently brush and floss the visible crown of our teeth, neglecting the subgingival area can have detrimental consequences. Food debris and bacteria can accumulate below the gum line, leading to plaque and calculus buildup. This can trigger inflammation and infection, causing gum disease, also known as periodontal disease.
Periodontal disease is not merely a concern for your gums; it can significantly impact your oral and overall health. Left untreated, it can damage the supporting bone and tissues, eventually leading to tooth loss. Moreover, research has linked periodontal disease to an increased risk of other health conditions, such as heart disease, stroke, and diabetes.
Maintaining a Healthy Subgingival Environment: A Collaborative Effort
Taking care of the hidden portion of your teeth requires a two-pronged approach: meticulous home care and regular professional cleanings.
At Home:
| • |
Brushing: Use a soft-bristled toothbrush and gentle circular motions to clean both the visible and subgingival areas. Consider using an electric toothbrush with a rotating head for better reach beneath the gum line. |
| • |
Flossing: Daily flossing is crucial for removing plaque and food particles trapped between teeth, where your toothbrush can't reach. |
| • |
Interdental brushes: For wider gaps between teeth, interdental brushes can be a helpful addition to your cleaning routine. |
| • |
Mouthwash: An antiseptic mouthwash can help reduce bacteria growth and freshen breath. |
Professional Care:
| • |
Regular dental checkups: Visiting your dentist every six months allows for a thorough examination of your teeth and gums. They can detect early signs of periodontal disease and provide appropriate treatment before it progresses. |
| • |
Professional cleanings: During your checkups, your dentist or hygienist will perform a professional cleaning, removing plaque and calculus even below the gum line. |
Conclusion: Embracing Comprehensive Oral Care
By understanding the hidden world beneath our gums and adopting a comprehensive oral care routine, we can effectively protect our teeth and maintain optimal oral health. Remember, prevention dentistry is key – taking care of your subgingival area is an investment in your long-term well-being. |
