Front Tooth Resin Veneers, Yonsei JW Dental Clinic

Hello, this is Yonsei JW Dental Clinic in Gangnam, Seoul, Korea

In our previous post, we explained laminate treatment, and today, we would like to talk about resin treatment for front teeth.

Resin treatment for front teeth is typically performed in the following cases:

  • Abnormal tooth shape due to microdontia or malformed teeth

  • Gaps between the front teeth (diastema)

  • Black triangles caused by gum recession

  • Chipped or worn-down teeth

Microdontia refers to teeth that are smaller than the normal size, commonly seen in the upper lateral incisors. Diastema, also known as midline diastema, is the space between the front teeth and is often treated for aesthetic or pronunciation reasons. Black triangles occur when gum and bone recession expose spaces between teeth, making them appear open.

Possible prosthetic treatment options for front teeth include:

  • Laminate treatment

  • Resin treatment

  • Crown treatment

  • Orthodontic treatment (for cases with spacing between front teeth)

Laminate veneers, which we discussed in a previous post, are made of ceramic (porcelain) and highly depend on the technique and skill level of the dental technician who fabricates them.

On the other hand, resin treatment can be completed in a single visit to the dental clinic and is more cost-effective compared to laminates. However, it requires significant effort from the dentist, and the outcome varies greatly depending on the dentist's expertise and skill level.

Resin veneer treatment, which is similar to laminate veneers, requires a significant amount of hands-on work by the dentist, making it a time-consuming procedure. Since it limits the number of patients a dentist can see in a day, it is not commonly performed. Unlike laminates, which require a dental lab, resin veneers are directly applied by the dentist to reshape or recolor the teeth, allowing for same-day treatment completion.

At Yonsei JW Dental Clinic, Dr. Ji Ho Ahn has extensive experience in resin treatments and delivers exceptional quality results, making this a highly recommended option for patients.

Before / After

In cases of microdontia, the small tooth size creates dark, empty spaces, leading to an unesthetic appearance. To address this,treatment options include laminate veneers, crowns, and resin veneers.

This treatment not only focuses on closing the gaps between the teeth but also considers the occlusion (bite) between the upper and lower front teeth. After evaluating factors such as treatment cost and duration, the patient opted for resin veneer treatment, which can be completed in a single visit.

Before / After

This patient previously had their diastema (gap between front teeth) filled with resin but visited our clinic due to partial chipping. Since they did not want any additional tooth reduction and were generally satisfied with their previous resin treatment, we removed the old resin and reshaped the area with new resin to restore its form.

Before / After

The patient had previously received several resin treatments for cervical wear, but over time, some areas had become discolored, and the edges of the front teeth were chipped. Additionally, the patient wanted to improve the slight misalignment of their teeth but was not considering orthodontic treatment. We proceeded with resin veneer treatment to restore the shape and appearance of the teeth. After the treatment, the patient was extremely satisfied with the results.

Before / After

The patient was experiencing significant stress due to the dark, visible space caused by gum recession and bone absorption. We filled that area with resin, addressing their aesthetic concerns.

While it's true that resin may discolor over time, the advantages include the ability to complete the treatment on the same day, no need to reduce the tooth structure, and a more cost-effective option compared to other prosthetic treatments. Additionally, resin can be removed and replaced in the future if necessary. When chosen for the right cases, resin treatment is a highly appealing solution.
