[Health Column] Gaps Between Front Teeth and Tooth Shape Irregularities: 7 Steps to Refining with Resin Restoration While Preserving Teeth

 

Hello, I am Hong-yeol Moon, Chief Director of Seoul Barun Implant Dental Clinic. 🦷

 

This patient visited because they were concerned about the gaps between their front teeth and the shape of their teeth. Since the front teeth are the first thing visible when smiling or speaking, even small gaps or differences in shape can feel significant to the patient.

 

The examination revealed that this was a case where the gaps between the teeth could be narrowed and the shape refined using resin restorations without significant tooth reduction. Rather than excessive treatment, I formulated a treatment plan that aimed to preserve the current teeth as much as possible while ensuring a natural appearance.

 

Below, I will organize this case step-by-step, following the photo sequence from pre-treatment data to post-treatment data.

 

🔎 Key factors considered when establishing a treatment plan

The goal of anterior resin restoration is not merely to fill the gap. I first checked the proportions of the teeth on both sides and the overall balance visible when smiling, and after examining the width of the space and the inner shape of the teeth from various angles, I planned the procedure to ensure the resin would not look too thick or awkward.

 

Since resin treatment involves building up the material to match the color and shape of the natural tooth, it is crucial to observe the color, translucency, and harmony with surrounding teeth in detail before treatment. Therefore, in this case as well, we proceeded with a focus on preserving the tooth by comparing the frontal, proximal, and occlusal plane data one by one.

📸 Photo 1 — Front view before treatment

Frontal photograph before treatment · Checking for spaces between front teeth and differences in tooth length and width

This is a frontal photograph taken before treatment. There was a gap between the front teeth, and the teeth appeared slightly different in length and width, which could make the overall impression feel unbalanced. At this stage, I did not simply focus on filling the space; instead, I also assessed the proportions of the teeth on both sides and the overall balance visible when smiling.

This is a close-up photo of the front teeth. You can check the color and translucency of the tooth surface, as well as its harmony with the surrounding teeth. Since resin treatment involves building up the material to match the color and shape of the natural tooth, such detailed observation before treatment is very important.

 

📸 Photo 3 — Occlusal surface photo

Occlusal surface photograph · Confirmation of the width of the space between the front teeth and the location requiring resin restoration

This is a photo taken from the occlusal side. I was able to see the space between the front teeth and the location requiring resin treatment more clearly. From this angle, I assessed the width of the space and the inner shape of the teeth to plan the treatment so that the resin would not appear too thick or unnatural.

Primary Trimming · The process of aligning the width, length, and contact points of the teeth

This is the process of filling and refining the resin in the first stage. For front tooth resin, it is important to shape the tooth gradually to match the width, length, and contact points, rather than completing it all at once. Since the final step is not yet finished, additional adjustments were made while observing the overall shape.

Secondary Trimming · Adjusting shape and surface texture to be close to natural teeth

This is the second trimming process. I adjusted the resin to make its shape and surface texture more natural and to ensure the boundary with the surrounding teeth does not look awkward. In anterior tooth restorations, I place greater importance on the finishing touch that makes the tooth look like a natural tooth when illuminated, rather than simply filling the gap.

 

📸 Photo 6 — Front view after treatment

Frontal view after treatment · Reduced space and improved tooth shape

This is a frontal photo taken after treatment. As the gap between the front teeth has narrowed and the tooth shape has been refined, the overall impression appears slightly more stable. Although resin treatment is a relatively conservative method, regular check-ups are necessary as discoloration or wear may occur depending on the patient's care habits.

 

📸 Photo 7 — Reconfirming pre-treatment condition

Check the changes by viewing the before-treatment comparison photos and after-treatment results side by side.

This is a photo that allows you to re-examine the condition before treatment. When compared to the post-treatment result, the differences in space and shape are more clearly visible. Through such before-and-after comparisons, I explain to the patient what has changed and how best to manage the condition going forward.

 

🪥 About post-treatment care

Although resin restorations are a conservative treatment that does not require significant tooth removal, proper care after treatment is crucial for maintaining the results for a long time. Since discoloration or wear on the resin surface can occur depending on the patient's care habits, it is recommended to undergo regular checkups to monitor the condition of the restoration and its boundary with surrounding teeth.

 

 

I do not simply define the completion of treatment to the patient as the point at which the resin is filled. Only when I verify that the tooth does not look unnatural under light and that it is in a shape that can be easily maintained can it be considered a stable treatment.

 

 

 

🗣️ Frequently Asked Questions (FAQ)

Q1. Is the gap between the front teeth treated only with resin?

A. In this case, the space could be reduced and the shape refined using resin restoration without significant tooth reduction. Since the appropriate method may vary depending on the condition of the tooth and the size of the space, it will be determined after an examination.

 

Q2. Is the resin completed in one go?

A. For anterior resin fillings, it is important to shape the tooth's width, length, and contact points gradually rather than completing it all at once. This case was also finished after undergoing first and second trimming.

 

Q3. Can the color change after resin treatment?

A. Discoloration or wear may occur on the resin surface depending on the patient's care habits. We check the condition through regular inspections and provide guidance on maintenance methods if necessary.

 

Q4. What is important to make them look like natural teeth?

A. It is important to observe the color, translucency, and harmony of the tooth surface with surrounding teeth in detail before treatment, and to finish the shape and surface texture so that it looks like a natural tooth when exposed to light.

 

To summarize this case

This is a resin restoration case that went beyond simply filling the gap between the front teeth; it involved preserving the existing teeth as much as possible while checking the proportions of the teeth on both sides and the overall balance, followed by first and second trimming to achieve a natural finish. Even for the same space between the front teeth, the treatment method and scope can vary depending on the shape of the teeth, the width of the space, and harmony with surrounding teeth; therefore, precise observation and sufficient consultation are required before treatment.
