Gum Recession Explained: Signs & Complications

Updated: Mar 6

Gum recession is a common dental condition where the gums gradually pull back from the teeth, exposing more of the tooth root. This can lead to tooth sensitivity, decay, and other oral health issues if left untreated. Understanding the signs, symptoms, and causes of gum recession is essential for maintaining healthy gums and teeth.

Gum Recession

Gum recession happens when the gum tissue encircling the teeth diminishes or recedes, revealing the tooth roots. Several factors contribute to this condition, such as gum disease, vigorous tooth brushing, inadequate oral hygiene habits, genetic predisposition, hormonal fluctuations, smoking, and bruxism.

Signs and Symptoms:

  • Exposed Tooth Roots: One of the most noticeable signs of gum recession is when the roots of the teeth become visible, making the teeth appear longer than usual.

  • Tooth Sensitivity: Receding gums can expose the sensitive roots of the teeth, leading to increased sensitivity to hot, cold, sweet, or acidic foods and beverages.

  • Bleeding Gums: Gums that exhibit frequent bleeding, particularly when brushing or flossing, could be a potential sign of gum recession and an underlying gum ailment.

  • Swollen or Red Gums: Inflammation and redness along the gumline may be a sign of gum recession and gum disease.

  • Loose or Shifting Teeth: As gum recession progresses, the supporting structures of the teeth may weaken, causing teeth to become loose or shift out of position.

It's essential to seek prompt dental care if you notice any signs or symptoms of gum recession to prevent further damage to your oral health.

Causes of Gum Recession:

Gum recession happens when the gum tissue encasing the teeth erodes or retreats, revealing a greater portion of the tooth or its root. Numerous factors may play a role in the development of gum recession, such as:

Insufficient Dental Care:

Insufficient brushing and flossing practices can result in the accumulation of plaque and tartar along the gumline, potentially leading to gum recession over time.

Excessive force while brushing your teeth or utilizing a toothbrush with stiff bristles can harm the sensitive gum tissue, potentially exacerbating recession.

Genetic Factors:

Genetic predisposition may render some individuals more susceptible to gum recession, indicating that even with diligent oral hygiene routines, they may still be at a heightened risk of developing this condition.

Periodontal diseases such as gingivitis and periodontitis can cause the gums to recede as the infection damages the gum tissue and supporting bone.


Grinding or clenching your teeth, particularly during nighttime sleep, can exert undue force on both your teeth and gums, potentially resulting in recession.

Tobacco Use:

Smoking or using smokeless tobacco products can increase the risk of gum disease, which in turn can lead to gum recession.

Misaligned Teeth:

Crooked or misaligned teeth can create areas where plaque and tartar accumulate more easily, increasing the risk of gum disease and recession.


Gum recession can lead to several complications, including:

  1. Tooth Sensitivity: Exposed tooth roots resulting from gum recession may lead to heightened tooth sensitivity when consuming hot, cold, or sugary foods and drinks.

  2. Increased Risk of Tooth Decay: When the roots of the teeth become exposed, they are more susceptible to decay since they lack the protective enamel covering.

  3. Gum Disease Progression: Gum recession can exacerbate existing gum disease or make it more difficult to manage, leading to further tissue loss and potential tooth loss if left untreated.

  4. Cosmetic Concerns: Receding gums can affect the appearance of your smile, making your teeth appear longer and causing an uneven gumline.

  5. Bone Loss: Severe gum recession can lead to loss of the bone that supports the teeth, increasing the risk of tooth mobility and eventual tooth loss.

  6. Compromised Tooth Stability: As the gum tissue recedes and bone loss occurs, the stability of the affected teeth may be compromised, leading to loosening or shifting of the teeth.

It's essential to address gum recession promptly to prevent further complications and preserve oral health. Regular dental check-ups and professional cleanings can help identify and address early signs of gum recession before they progress. Additionally, practicing good oral hygiene habits, avoiding tobacco use, and seeking treatment for gum disease can help prevent or manage gum recession.


Diagnosing gum recession typically involves a comprehensive dental examination by a dentist or periodontist. During the evaluation, the dental professional will:

  1. Visual Inspection: The dentist will visually inspect the gums to look for signs of recession, such as gum tissue pulling away from the teeth, exposed tooth roots, and changes in gum color or texture.

  2. Measurement of Gum Recession: Using a periodontal probe, the dentist will measure the depth of the gum pockets around each tooth. Deeper pockets indicate more severe gum recession and may signal underlying gum disease.

  3. X-rays: X-rays may be taken to assess the extent of bone loss around the affected teeth, which can contribute to gum recession and affect treatment planning.

  4. Review of Medical History: The dentist may inquire about your medical history, including any existing health conditions or medications that could affect gum health.

  5. Discussion of Symptoms: If you're experiencing symptoms such as tooth sensitivity, pain, or changes in the appearance of your gums, be sure to communicate these to your dentist during the evaluation.

Based on the findings of the examination, the dentist will determine the severity of the gum recession and recommend appropriate treatment options.

Gum Recession

Treatment Options:

The treatment plan for gum recession varies depending on factors such as the root cause, the extent of recession, and individual patient characteristics. Typical treatment options could encompass:

Improved Oral Hygiene:

Practicing proper brushing and flossing techniques and using a soft-bristled toothbrush can help prevent further gum recession and promote gum health.

Also known as deep cleaning, this non-surgical procedure involves removing plaque and tartar from below the gumline and smoothing the root surfaces to promote gum tissue reattachment and reduce inflammation.

Gum Grafting: 

In cases of significant gum recession, a gum grafting procedure may be recommended to cover exposed tooth roots and restore gum tissue. During the procedure, tissue is taken from another area of the mouth or a donor source and placed over the receded gums to augment tissue volume and support.

Periodontal Surgery: 

In advanced cases of gum recession or associated periodontal disease, surgical intervention may be necessary. Procedures such as pocket reduction surgery, guided tissue regeneration, or bone grafting may be performed to address underlying issues and restore gum health.

Orthodontic therapy:

Addressing teeth misalignment or bite problems could potentially redistribute pressure on the gums, thereby lowering the likelihood of gum recession. Options for orthodontic treatment may involve braces or transparent aligners.

Lifestyle Modifications: 

Making lifestyle changes such as quitting smoking, managing stress, and adopting a balanced diet can support gum health and prevent further recession.

It's essential to consult with a dental professional to determine the most appropriate treatment plan for your specific condition and address gum recession promptly to prevent further complications. Regular dental visits for preventive care and ongoing monitoring are crucial for maintaining healthy gums and overall oral health.
