Questions and Answers

Which of the following is NOT a possible cause of gingival recession?

Tongue thrusting

Mouth breathing

Dental fillings (correct)

Improper flossing technique

What is the primary reason why exposed dentin leads to tooth sensitivity?

Dentin contains nerve endings which are exposed when the gum recedes. (correct)

Dentin is naturally more sensitive to stimuli than enamel.

Exposed dentin is more susceptible to bacteria and infection.

Dentin is a softer tissue than enamel and therefore more easily damaged.

Study Notes

Recession Quiz - Question 1

A thin gingival biotype is characterized by delicate, almost translucent tissue.
This biotype often has a minimal zone of attached gingiva.
This makes the gums more vulnerable to recession, especially around restorations or traumatic events.

Gingival Recession - Question 2

Gingival recession is commonly observed in adults undergoing rapid orthodontic movement.
Adults' periodontal tissues are less adaptable than children's.
Orthodontic movement can put excess pressure on the gingiva and periodontium, disrupting tissue and leading to recession.

Sensitive Teeth - Question 3

Gingival recession exposes dentin, increasing sensitivity.
The exposed nerve endings are susceptible to stimuli like hot, cold, or sweet foods.

Measuring Gingival Recession - Question 4

The relevant anatomical landmarks are the cemento-enamel junction (CEJ) and the base of the periodontal pocket.
The distance from the CEJ to the base of the pocket is used to measure recession.

Inflammatory Causes of Gingival Recession

Periodontal Disease (Gingivitis and Periodontitis): Inflammation of gums and periodontium. Bacterial plaque triggers an inflammatory response.
Chronic Inflammation from Poor Oral Hygiene: Inadequate oral hygiene leads to ongoing irritation, gum inflammation, and tissue breakdown.
Overzealous Brushing (Traumatic Brushing): Harsh brushing techniques can cause microtrauma to the gum tissue, leading to a damaging inflammatory response.
Systemic Diseases (e.g., Diabetes, Autoimmune Disorders): Specific conditions impacting the body's immune response, blood sugar levels, and healing can increase gum recession risk.

Mechanical Causes of Gingival Recession

Traumatic Toothbrushing: Aggressive brushing, improper technique, or hard-bristled brushes can injure gum tissues, leading to recession in critical areas.
Improper Dental Restorations/Procedures: Improper restoration technique, shape, sizing, placement and/or contoured restorations and crowns can cause uneven pressure and trauma to surrounding gums, potentially producing recession.
Orthodontic Treatment: Rapid tooth movement during orthodontic therapy can produce mechanical stress on the gum tissue and supporting structures if the movement is too quick.
Tongue and Lip Habits: Chronic oral habits, like tongue thrusting or lip biting, and even chronic mouth breathing, cause abnormal mechanical stress to the gums.
Forceful Use of Toothpicks/Dental Floss: Excessive force during flossing or toothpick use can injure the gums, potentially causing recession.

Impact of Gingival Recession on Patients

Increased Tooth Sensitivity: Exposed dentin leads to heightened sensitivity to temperature and tactile stimuli.
Aesthetic Concerns: Exposed tooth roots may change the patient's smile's aesthetics and create a sense of self-consciousness.
Increased Risk of Tooth Decay: Exposed root surfaces are more prone to decay due to less mineralisation and lack of protective effects present in the enamel.
Compromised Periodontal Support: Loss of periodontal attachment compromises the structure supporting teeth, which could lead to tooth stability and loss if the recession progresses.
