Open bite with gingival swelling?


Hello, doctor.
I would like to ask about my dental issue.
I have an open bite problem, which has caused my molars to become flattened.
I had my wisdom teeth removed back in 2012, but now the area where my lower left wisdom tooth was extracted has swollen gums that are covering the molars in front, causing me significant pain and making it impossible to sleep at night.
I visited a dentist who informed me that my molars are positioned lower than the gums behind them, which creates gaps that can trap food debris and lead to recurring gum swelling.
She suggested that I undergo orthognathic surgery to correct my bite.
I have difficulty biting with my front teeth, and I have to use my tongue to push against my upper incisors to chew even soft foods like noodles.
I would like to know if undergoing orthognathic surgery and orthodontic treatment will allow my molars to be positioned higher than the gums behind them.

Dear Miss Hsiao-Hui: After orthognathic surgery and orthodontic treatment, the molars can be positioned higher than the posterior gums, and this is currently achievable! Please communicate more with your doctor! Thank you! Wishing you safety! Sincerely, Dr.

Jaw surgery, particularly orthognathic surgery, can indeed be a viable solution for correcting an open bite and addressing associated issues such as gum swelling and discomfort. An open bite occurs when the upper and lower teeth do not meet properly when the mouth is closed, which can lead to various complications, including uneven wear on teeth, difficulty chewing, and even speech issues. In your case, it seems that the open bite has contributed to the wear on your molars and has led to gum swelling in the area where your wisdom teeth were extracted.

The recommendation from your dentist to consider jaw surgery is based on the need to realign your jaw and teeth to achieve a proper bite. During orthognathic surgery, the surgeon will reposition the upper jaw (maxilla), lower jaw (mandible), or both to correct the misalignment. This realignment can help ensure that your molars are positioned correctly above the gum line, reducing the risk of food debris getting trapped and subsequently causing gum inflammation and pain.

In addition to the surgical correction, orthodontic treatment (braces or clear aligners) is typically required both before and after surgery to prepare the teeth for the new jaw position and to ensure that they settle into their new alignment properly. This comprehensive approach not only addresses the open bite but also improves overall dental aesthetics and function.

Regarding your specific concerns about whether the surgery will allow your molars to be positioned higher than the gum line, the answer is yes. Once the jaw is properly aligned, the teeth will be positioned correctly, which should alleviate the issues you are currently experiencing with gum swelling and discomfort. However, it is essential to have a thorough discussion with your oral surgeon and orthodontist about your specific case, as they will provide personalized insights based on your dental structure and health.

It's also important to note that recovery from jaw surgery can take time, and you may experience swelling and discomfort during the healing process. Pain management and following post-operative care instructions will be crucial in ensuring a smooth recovery. Regular follow-ups with your dental team will help monitor your progress and address any concerns that may arise.

In summary, jaw surgery can effectively correct an open bite and alleviate associated gum issues. It is essential to work closely with your dental professionals to develop a comprehensive treatment plan that addresses your specific needs. With the right approach, you can achieve a healthier bite, improved oral function, and relief from the discomfort you are currently experiencing.
