How to Correct Uneven Gum Exposure When Smiling?

The gums are asymmetrical?

When I smile, the right side of my upper gums shows more than the left side.
What can I do to improve this? Also, I have only had seven upper teeth orthodontically treated; will my teeth become aligned?

Dr. Yang Hui reply Dentistry

Generally, very few people pay attention to whether the height of the gums on the upper left and right sides is the same, unless the difference is significant.
To improve this condition, it is essential to identify the underlying cause.
This could be due to dentures or periodontal disease leading to gum recession, or it may be related to the alveolar bone.
With the current information, it is not possible to provide a definitive solution for improvement.

Regarding orthodontics, if only seven teeth are being aligned, whether they will be straightened effectively is best answered by the treating dentist.
The dentist must believe that this approach will result in proper alignment.
If satisfactory answers cannot be obtained, it is advisable to seek treatment in person at the clinic.

Correcting uneven gum exposure when smiling, also known as "gummy smile," can be a multifaceted process that involves both orthodontic and possibly surgical interventions. The first step in addressing this issue is to understand the underlying causes of the asymmetry in gum exposure. Here are some common factors that can contribute to this condition:
1. Dental Alignment: If your teeth are misaligned, it can lead to uneven gum exposure. Orthodontic treatment, such as braces or clear aligners, can help align your teeth properly, which may also improve the appearance of your gums when you smile.

2. Gum Contour: The shape and contour of your gums can vary from one side of your mouth to the other. If one side has more gum tissue than the other, it can create an uneven appearance. In such cases, a procedure called gum contouring or gingivectomy may be recommended to reshape the gums and create a more symmetrical look.

3. Lip Position: The position of your lips when you smile can also affect how much gum is visible. If your upper lip is shorter or if there is excessive upper lip movement, it can expose more gum tissue on one side. In some cases, lip repositioning surgery may be considered to correct this.

4. Jaw Position: An improper bite or jaw alignment can also contribute to uneven gum exposure. If your jaw is not aligned properly, it may affect how your teeth and gums appear when you smile. Consulting with an orthodontist or oral surgeon can help determine if jaw surgery is necessary.

5. Muscle Function: The muscles that control your smile can also play a role. If the muscles on one side of your face are stronger or more active than the other, it can lead to asymmetry. In some cases, botulinum toxin (Botox) injections can be used to relax the muscles on the stronger side, creating a more balanced smile.

Regarding your specific situation, since you mentioned that you have only undergone orthodontic treatment for the upper seven teeth, it is essential to consult with your orthodontist about the potential for further treatment. They can assess whether additional orthodontic work is necessary to achieve a more uniform smile and if any of the aforementioned procedures would be beneficial.

In summary, the best approach to correct uneven gum exposure when smiling involves a comprehensive evaluation by dental professionals, including orthodontists and possibly periodontists or oral surgeons. They can provide a tailored treatment plan that may include orthodontic adjustments, gum contouring, or other surgical options to achieve a balanced and aesthetically pleasing smile. Regular follow-ups and open communication with your dental care team will be crucial in achieving your desired results.

Gingival recession is typically first evaluated by an orthodontist to determine if there are any issues with the dental arch or occlusion. Once the fundamental problems are addressed, we can discuss whether soft tissue adjustments are necessary.
