Tooth Length Changes: Causes and Solutions

Teeth elongate as they grow downward?

Hello doctor, I have noticed that my upper front teeth seem to have grown downwards.
It feels like my teeth have become longer; when I smile, my teeth show more than before.
They almost touch my lower lip, and I can also see a bit of gum.
Additionally, my front teeth appear larger and longer than they used to be.
I do not have any cavities or missing teeth, and I am unsure what to do.
Is there a way to return my teeth to their original length? Thank you.

Dear Ms.
Wu,
Hello! Based on what you described, there could be two possible conditions:
1.
Periodontal disease, which can cause gum recession and expose the tooth roots, making the teeth feel longer.
2.
You may have a deep bite, where the upper and lower teeth do not make contact, causing the upper teeth to elongate.
This condition would require orthodontic treatment.
The first condition would necessitate periodontal therapy.
Wishing you well!
Sincerely,
Dr.

More Info

Tooth length changes, particularly in the upper front teeth, can be a source of concern for many individuals. The perception that your teeth appear longer or that they are protruding more than before can be attributed to several factors, including periodontal disease, changes in occlusion, and natural wear and tear over time.

One of the primary causes of teeth appearing longer is periodontal disease, which leads to gum recession. As the gums recede, more of the tooth root becomes exposed, giving the illusion that the tooth is longer than it actually is. This condition can also lead to sensitivity and increased risk of cavities if the root surfaces are not properly cared for. If you suspect gum recession, it is crucial to consult with a dental professional who can assess your gum health and recommend appropriate treatments, which may include deep cleaning or gum grafting procedures.

Another possible reason for the perceived elongation of your teeth is a condition known as deep bite or overbite. In this scenario, the upper teeth may not make proper contact with the lower teeth during biting and chewing. As a result, the upper teeth can continue to erupt over time, leading to an increase in their length. Orthodontic treatment may be necessary to correct the bite and prevent further elongation of the teeth. This could involve braces or other orthodontic appliances designed to realign the teeth and improve the overall bite.

Additionally, natural wear and tear can contribute to changes in tooth length. Over the years, teeth can undergo changes due to grinding (bruxism), which can wear down the biting surfaces and alter their appearance. If you grind your teeth, it may be beneficial to discuss options such as a night guard with your dentist to protect your teeth from further wear.

If you are looking to address the issue of your teeth appearing longer, there are several treatment options available. If gum recession is the underlying cause, periodontal treatment may help restore gum health and reduce the appearance of elongated teeth. If orthodontic issues are present, braces or aligners can help reposition the teeth and improve your bite. In cases where the teeth are excessively worn down, cosmetic procedures such as dental bonding or veneers may be considered to enhance the appearance of your smile.

In summary, the perception of longer teeth can arise from various factors, including gum recession, bite issues, and natural wear. It is essential to consult with a dental professional who can evaluate your specific situation and recommend the most appropriate treatment options. Regular dental check-ups and maintaining good oral hygiene practices are crucial in preventing further changes in tooth length and ensuring overall dental health.
