A gap between two teeth, commonly between the upper front teeth, is medically known as a diastema. Many individuals seek methods to close this space without committing to the multi-year process of traditional metal braces. Modern dentistry offers several professional, non-orthodontic options that can quickly and effectively alter the appearance of a teeth gap. These professional solutions focus on cosmetic alteration rather than tooth movement. This article will explore these options and provide warnings about dangerous at-home methods.
Cosmetic Dental Procedures
The fastest and most popular non-braces methods for closing a diastema involve adding tooth-colored material to reshape the teeth. These procedures work by widening the two teeth adjacent to the gap, visually eliminating the space. The two primary approaches are dental bonding and porcelain veneers, which differ in material, longevity, and cost.
Dental bonding is the most conservative and least expensive treatment, often completed in a single appointment. The dentist applies a composite resin, a putty-like, tooth-colored plastic material, directly to the edges of the teeth surrounding the gap. This material is sculpted to fill the space and then hardened using a curing light. Bonding is ideal for small to moderate gaps and costs between $300 and $600 per tooth. However, the resin is prone to staining and generally lasts between three to ten years before needing replacement.
A more durable option is the application of porcelain veneers. Veneers are custom-made, thin shells of ceramic that are permanently bonded to the front surface of the teeth. Unlike bonding, this procedure requires the removal of a small amount of enamel to ensure the veneer sits flush and looks natural. The porcelain material is resistant to staining and wear, offering a longer lifespan, typically 10 to 15 years or more. This increased durability and aesthetic quality come with a higher cost, often ranging from $1,000 to $2,500 per tooth.
Addressing Gaps Caused by Tissue
In some cases, a diastema is caused not by tooth size but by an anatomical soft tissue structure called the labial frenum. The labial frenum is a fold of tissue connecting the center of the upper lip to the gum line, located above the two front teeth. If this frenum is thick or extends too low, it can physically prevent the front teeth from coming together, creating or maintaining a gap.
When an excessive frenum causes the gap, a surgical procedure called a frenectomy is recommended. This procedure involves removing or repositioning the tissue, which eliminates the tension or pulling force on the gums. A frenectomy is a quick, minor procedure performed with a scalpel or a soft-tissue laser, using local anesthesia. The procedure alone rarely closes a pre-existing gap completely in adult teeth. However, its purpose is to remove the underlying biological cause that could otherwise cause the gap to reopen after cosmetic treatment. Therefore, a frenectomy is often performed before or during the process of closing the space with materials like bonding or veneers to ensure long-term stability.
The Dangers of DIY Teeth Gap Closures
The desire for a quick, cheap fix has led to the dangerous trend of attempting to close a diastema using non-professional, do-it-yourself methods. The most common and hazardous practice involves placing small elastic bands or hair ties around the two gapped teeth to pull them together. This practice is strongly discouraged by dental professionals due to the severe and often irreparable damage it causes.
The danger stems from the uncontrolled force the elastic band applies to the teeth. Unlike professional orthodontic forces, which are carefully calibrated to move the tooth crown and root simultaneously, the elastic band tends to slip toward the path of least resistance. The band can migrate down the tooth and into the gum line, wrapping around the root structure. Once lodged beneath the gum tissue, it destroys the delicate ligaments, bone, and soft tissue that hold the tooth in its socket. This process rapidly leads to root damage, severe periodontal destruction, and bone loss, often requiring surgery just to remove the embedded band. The uncontrolled movement and subsequent damage can cause the teeth to become loose or even fall out entirely. Attempting to use ill-fitting, online-purchased clear aligners without professional supervision also carries risks, as only a qualified professional can assess the health of the bone and root structure before initiating tooth movement. Individuals seeking to close a gap should always consult a dentist or orthodontist to ensure a safe outcome.
