Will Missing Teeth Affect the Height of Adjacent Teeth?

Missing teeth not replaced?

Hello Doctor: I have a missing tooth.
On the left side, there is a dental implant, and on the right side, there is a prosthetic tooth.
Both of these adjacent teeth are occluding with the lower teeth on either side of the missing tooth.
If the missing tooth is not replaced, will the lower teeth grow taller?

If the crowns of the teeth on both sides of a missing tooth are occluding with the corresponding lower teeth, the lower teeth not only become taller, but the missing tooth area can lead to a reduced ability to withstand opposing forces on the crowns during occlusion.
It is advisable to consult a dentist to evaluate whether it is possible to restore the missing tooth area with dental implants and crowns.

Missing teeth can significantly affect the height and alignment of adjacent teeth, as well as the overall occlusion (bite) of the dental arch. When a tooth is lost, the surrounding teeth may shift or drift into the space left by the missing tooth. This can lead to several complications, including changes in the height of the adjacent teeth and the opposing teeth in the opposite arch.

In your case, since you have a missing tooth with a dental implant on one side and a prosthetic tooth (dentures) on the other, the adjacent teeth will likely experience some changes. When a tooth is missing, the teeth on either side may tilt or move towards the gap. This movement can lead to an increase in the height of the adjacent teeth, particularly if they are constantly engaging with the opposing teeth during chewing. The forces exerted during biting can cause the adjacent teeth to extrude (move outward) over time, potentially leading to a situation where they become taller than their original height.

Moreover, the lower teeth that are in contact with the missing tooth area may also experience changes. If the upper teeth are not properly supported by the missing tooth, the lower teeth may drift upwards, leading to an uneven bite and further complications. This can create a scenario where the lower teeth appear to be "growing" taller, as they are compensating for the missing upper tooth.

It's essential to address missing teeth promptly to prevent these issues. Dental professionals often recommend replacing missing teeth with dental implants, bridges, or dentures to maintain the integrity of the dental arch and prevent adjacent teeth from shifting. In your case, since you already have an implant and a prosthetic tooth, it would be advisable to consult with your dentist about the best options for restoring the missing tooth. This could involve placing a dental implant in the gap or considering other restorative options that can help maintain the height and alignment of your teeth.

In summary, missing teeth can indeed affect the height of adjacent teeth, leading to potential complications in your bite and overall dental health. It is crucial to seek professional dental advice to evaluate your specific situation and determine the best course of action to restore your dental arch and maintain proper occlusion. Regular dental check-ups and timely interventions can help prevent further complications and ensure the longevity of your dental health.
