In your case, you mention experiencing noticeable gum recession on the lower left side and that your gums bleed when brushing lightly. Bleeding gums are often indicative of inflammation or periodontal disease. Given that you maintain good oral hygiene practices flossing regularly, not smoking, and visiting a hygienist every six months—it’s crucial to consider other factors that may contribute to your condition.
Dentists typically measure the depth of the gingival sulcus (the space between the tooth and gum) using a periodontal probe. A measurement greater than 3 mm may indicate significant recession.
Noticing exposed roots or sensitivity while eating hot or cold foods can also indicate severe recession.
If you are experiencing significant bleeding despite gentle brushing techniques, this could suggest underlying inflammation or infection that needs addressing.
A specialist can provide a thorough examination and recommend treatment options which best suits to your specific situation.
