Gum Recession: Causes, Risks, and Treatment Options 牙齦萎縮：原因、風險和治療選擇

Jun 19

Gum recession — the gradual exposure of tooth roots as gum tissue pulls back — is one of the most common yet underappreciated dental problems. Many patients first notice it as tooth sensitivity to cold or hot foods, or as teeth that appear longer than they once did. What may seem like a cosmetic concern is often a sign of a deeper problem that, left untreated, can lead to root decay, bone loss, and eventually tooth loss.

At Pleasant Dental Associates, Dr. Jerry Chiu evaluates and treats gum recession regularly, helping patients understand the underlying cause and the most effective path to correction.

What Causes Gum Recession?

Gum recession rarely has a single cause. The most common contributing factors include:

Periodontal disease — the most significant cause; bacterial infection destroys gum and bone tissue
Aggressive brushing — scrubbing too hard or using a hard-bristled brush wears away gum tissue over time
Genetics — some patients are born with naturally thin or fragile gum tissue that is more susceptible to recession
Teeth grinding (bruxism) — the forces generated by grinding put excessive stress on the gum attachment
Misaligned teeth — teeth that are positioned outside the natural arch can have thin or absent bone over the root, making the gum more vulnerable
Piercings — lip or tongue piercings that repeatedly contact the gum can cause localized recession

Why Recession Should Not Be Ignored

When gum tissue recedes, it exposes the root surface of the tooth. Unlike enamel, root surfaces are not covered by a hard protective layer — they are vulnerable to decay, sensitivity, and wear. Recession also reduces the attachment that anchors gum tissue to the tooth, and once gum tissue is lost, it does not grow back on its own. Without treatment, recession tends to progress.

Beyond individual tooth health, widespread recession is often a visible sign of underlying periodontal disease that requires evaluation and treatment of the infection before the recession itself is addressed.

Treatment Options for Gum Recession

Gum Grafting (Connective Tissue Graft)

The most established and effective treatment for gum recession is a connective tissue graft, in which a small amount of tissue is taken from the roof of the mouth (palate) and used to cover the exposed root and rebuild the gum level. The procedure is performed under local anesthesia, and results are predictable and long-lasting when performed by an experienced periodontist.

Pinhole Surgical Technique

A minimally invasive alternative to traditional grafting, the pinhole technique involves making a small access point in the gum tissue and gently repositioning existing tissue over the exposed roots. It involves no donor site and typically results in faster recovery. Your periodontist will advise whether this is appropriate for your case.

Treating the Underlying Cause

In all cases, correcting the underlying cause of recession is essential. This may include treating active periodontal disease, adjusting brushing technique, recommending a night guard for grinding, or discussing orthodontic options for misalignment.

Frequently Asked Questions

Will my gums grow back on their own?

No. Once gum tissue has receded, it will not regenerate without surgical intervention. This is one of the key reasons not to wait — recession typically progresses rather than stabilizing.

Is gum grafting painful?

The procedure is performed under local anesthesia. The donor site at the palate is typically the source of any post-operative tenderness, which resolves within one to two weeks. Most patients find the recovery more manageable than expected.

Is gum recession a sign of gum disease?

It can be, but not always. Recession caused by aggressive brushing or thin tissue type may occur without active infection. A comprehensive periodontal evaluation will determine the cause and guide treatment.

Can recession affect implants?

Yes. Recession around implants — called peri-implant recession — can expose the implant surface and affect both function and aesthetics. Grafting around implant sites is a service we provide.

牙齦萎縮：原因、風險和治療選擇

牙齦萎縮——牙齦組織退縮時牙根逐漸暴露——是最常見但被低估的牙科問題之一。許多患者首先注意到它表現為對冷熱食物的牙齒敏感，或者牙齒看起來比以前更長。看似美觀問題的現象往往是更深層問題的跡象，如果不治療，可能導致根部齲齒、骨質流失，最終導致牙齒脫落。

在 Pleasant Dental Associates，邱醫師定期評估和治療牙齦萎縮，幫助患者了解根本原因和最有效的矯正途徑。

是什麼導致牙齦萎縮？

牙齦萎縮很少有單一原因。最常見的影響因素包括：

牙周病——最重要的原因；細菌感染破壞牙齦和骨骼組織
過度刷牙——刷得太用力或使用硬毛牙刷會隨時間磨損牙齦組織
遺傳——有些患者天生牙齦組織較薄或較脆弱，更容易萎縮
磨牙症——磨牙產生的力量對牙齦附著造成過度壓力
牙齒錯位——位於自然牙弓之外的牙齒牙根上方骨骼薄或缺失，使牙齦更脆弱
穿刺飾品——反覆接觸牙齦的嘴唇或舌頭穿環可能導致局部萎縮

為什麼不應忽視牙齦萎縮

當牙齦組織萎縮時，牙齒的根面會暴露。與牙釉質不同，根面沒有堅硬的保護層覆蓋——它們容易受到齲齒、敏感和磨損的影響。萎縮還減少了將牙齦組織固定在牙齒上的附著，一旦牙齦組織失去，它就不會自行再生長。如果不治療，萎縮往往會繼續進展。

除了個別牙齒健康之外，廣泛的萎縮通常是潛在牙周病的可見跡象，需要在解決萎縮本身之前評估和治療感染。

牙齦萎縮的治療選擇

牙齦移植（結締組織移植）

牙齦萎縮最成熟且最有效的治療方法是結締組織移植，從口腔上顎取少量組織，用於覆蓋暴露的牙根並重建牙齦水平。手術在局部麻醉下進行，由經驗豐富的牙周病專科醫師操作時結果可預測且持久。

微創針孔手術技術

作為傳統移植的微創替代方案，針孔技術涉及在牙齦組織中製作一個小入口，輕輕地將現有組織重新定位到暴露的牙根上。它不需要供體部位，通常恢復更快。您的牙周病專科醫師將建議這是否適合您的情況。

治療根本原因

在所有情況下，糾正萎縮的根本原因都是必不可少的。這可能包括治療活躍的牙周病、調整刷牙技術、推薦防磨牙板或討論錯位的正畸選擇。

常見問題

我的牙齦會自行生長回來嗎？

不會。一旦牙齦組織萎縮，它在沒有手術干預的情況下不會再生。這是不要等待的關鍵原因之一——萎縮通常會繼續進展而不是穩定。

牙齦移植手術會痛嗎？

手術在局部麻醉下進行。上顎供體部位通常是任何術後觸痛的來源，在一到兩週內消退。大多數患者發現恢復比預期更容易管理。

牙齦萎縮是牙周病的跡象嗎？

可能是，但並非總是如此。由過度刷牙或薄牙齦組織類型引起的萎縮可能在沒有活躍感染的情況下發生。全面的牙周評估將確定原因並指導治療。

牙齦萎縮會影響植體嗎？

是的。植體周圍的萎縮——稱為種植體周圍萎縮——可以暴露植體表面並影響功能和美觀。我們提供植體部位周圍的移植服務。
