Can excessive internal heat (shang huo) cause gum recession?

Introduction

"Shanghuo" (excessive internal heat) mainly manifests as symptoms such as redness, swelling, pain, and ulcers of the oral mucosa. It does not directly damage gingival tissues or alveolar bone, and therefore does not directly cause gum recession. The primary cause of gum recession is long-term bacterial invasion of periodontal tissues. Even if symptoms of "shanghuo" occur, the gums typically do not recede if oral hygiene is good and there is no periodontal inflammation.

Simple "heatiness" does not directly cause gum recession, but if periodontal inflammation is present during episodes of heatiness, it may worsen existing recession or accelerate its progression. The condition should be assessed in conjunction with overall oral health. If persistent gum redness, swelling, or bleeding occurs during heatiness, prompt medical attention is necessary to prevent worsening inflammation that could trigger or accelerate gum recession.

Heatiness typically manifests as redness, pain, and ulcers in the oral mucosa. It does not directly damage gum tissue or alveolar bone, and therefore does not directly lead to gum recession. The primary cause of gum recession is long-term bacterial attack on periodontal tissues. Even when experiencing symptoms of heatiness, individuals with good oral hygiene and no underlying periodontal inflammation usually do not develop gum recession.

However, heatiness can temporarily reduce the body's resistance. If uncontrolled periodontal inflammation already exists in the mouth, bacteria may multiply more easily, exacerbating symptoms such as gum redness, swelling, and bleeding. This in turn accelerates the destruction of gum tissue and alveolar bone, making mild recession more apparent or causing existing recession to progress further.

In daily care, maintain regular作息 (sleep patterns), eat a light diet, and minimize occurrences of heatiness. Consistently brush teeth twice daily with a soft-bristled toothbrush, clean between teeth with dental floss after meals, and have a professional periodontal examination and cleaning every six months to one year.

Are there any side effects of dental implants?

Dental implants involve surgically placing artificial teeth into the missing areas, with a cost of approximately 5,000 to 10,000 yuan per tooth. However, dental implants may cause side effects such as bleeding, infection, occlusion problems, gum recession, and nerve damage. The specific side effects vary from person to person. To reduce the risks, it is recommended to choose a reputable and professional hospital and to be guided by a qualified dentist.

Will gum recession continue to progress?

If gingival recession is caused by factors such as periodontitis, long-term improper brushing techniques, or malaligned teeth and remains untreated, the inflammation will continuously destroy the gums and alveolar bone, leading to further gum recession and increased exposure of tooth roots. This may also be accompanied by problems such as tooth mobility and sensitivity, creating a vicious cycle that progressively worsens the recession.

Can tooth brushing cause gum recession?

In general, whether tooth brushing causes gum recession depends on the brushing technique. Brushing teeth properly usually does not lead to gum recession, but improper brushing techniques may cause it. To prevent gum recession, it is important to choose a soft-bristled toothbrush, learn and consistently use the correct brushing method, control brushing pressure, and avoid overzealous cleaning.

Can receding gums recover?

Gingival recession is generally difficult to completely cure, but its progression can be controlled and symptoms improved through treatment. In daily life, it's important to use a soft-bristled toothbrush and the Bass brushing technique, avoiding aggressive brushing that may damage the gums. Rinse your mouth promptly after meals, and use dental floss or interdental brushes to clean between teeth, reducing the buildup of food debris.
