Introduction

A qualified retainer should fit precisely to the shape of the teeth and gums, with smooth edges that do not exert continuous pressure on the gums when properly worn. When used correctly, such retainers serve only to stabilize the position of the teeth, without damaging gum tissue or causing gum recession. On the contrary, by maintaining proper tooth alignment, they contribute to overall oral health.

Properly wearing a well-fitted retainer typically does not cause gum recession. However, if the retainer is ill-fitting, poorly cleaned, or worn incorrectly, it may lead to gum recession. If you experience any physical discomfort, it is recommended to seek medical attention promptly and follow professional medical advice for treatment.

A qualified retainer should precisely fit the shape of the teeth and gums, with smooth edges that do not continuously press against the gums when worn correctly. When used properly, such retainers serve only to stabilize tooth position without damaging gum tissue, thus preventing gum recession. On the contrary, by maintaining proper tooth alignment, they contribute positively to overall oral health.

If a retainer is improperly made—such as having excessively long or sharp edges, or dimensions that do not match the teeth—it can continuously rub against or compress the gums during wear. Over time, this may disrupt the attachment between the gums and teeth, leading to gradual gum recession and root exposure. Additionally, inadequate oral hygiene while wearing a retainer allows food debris to accumulate in the space between the retainer and gums, increasing the risk of gingivitis. Prolonged inflammatory irritation from such conditions can also result in gum recession.

Some individuals may exert excessive force when inserting the retainer or fail to follow medical instructions regarding wear time, causing undue strain on the gums. This too can damage gum tissue and eventually lead to recession. Therefore, it is essential to obtain retainers from reputable dental providers, strictly adhere to professional guidance, maintain excellent oral hygiene, and attend regular follow-up checkups.

Can dental implants be placed with gum recession?

Whether gum recession is suitable for dental implantation depends on the severity of the gum recession. In cases of mild gum recession with no obvious symptoms, dental implants can be considered under a doctor's guidance. However, severe gum recession that affects the health of the alveolar bone is unsuitable for implantation, as it may compromise the implant's effectiveness and lead to instability of the implant. If normal chewing is affected, tooth extraction may be considered under a doctor's guidance.

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.

Can gum recession be corrected by straightening teeth?

In general, whether orthodontic treatment is possible with gingival recession depends on the severity and control of the condition. Orthodontic treatment may proceed if the gum recession is mild and inflammation is under control. However, if the recession is severe or the inflammation remains unstable, orthodontics should be postponed until the gum problems are properly treated. Daily oral hygiene practices, including brushing teeth morning and evening, using dental floss to clean between teeth, and regular periodontal checkups and maintenance, are essential.

Can gaps between teeth be filled?

In general, whether a gap between teeth can be filled depends on the specific situation. Small physiological gaps without discomfort usually do not require repair. However, if the gap is too large, caused by tooth decay or gum recession, or affects eating and aesthetics, repair may be necessary. To maintain healthy spaces between teeth, it's important to brush teeth morning and night and use dental floss regularly.
