Should primary teeth be preserved in the absence of permanent teeth?


Hello, Dr.
Tseng.
I have a primary tooth with an underlying missing permanent tooth.
After getting a filling for the cavity in this primary tooth, the dentist initially assessed that the tooth could still be used.
However, after the filling, the gap between the primary tooth and the adjacent permanent tooth has become quite large, whereas it was previously very small.
I'm unsure if the small gap was due to the filling material or the condition of my original teeth.
The dentist has since changed their mind about the condition of the primary tooth and believes it should be addressed.
I would like to hear your opinion, as I still hope to keep my natural teeth as much as possible.

Dear Miss Wang,
The primary tooth has been filled due to decay, but after the filling, you feel that the gap with the permanent tooth has increased.
It is recommended that you have a thorough examination by a dentist to determine whether the primary tooth is inherently small or if there is decay on the adjacent surface of the permanent tooth, before deciding whether to retain the primary tooth.

Sincerely,
Director Tseng Guang-Hui, Department of Dentistry, Nantou Hospital

When it comes to the question of whether to keep baby teeth when permanent ones are missing, there are several important factors to consider. Baby teeth, or primary teeth, play a crucial role in a child's dental development. They not only help with chewing and speaking but also serve as placeholders for the permanent teeth that will eventually erupt. If a primary tooth is lost prematurely or is in poor condition, it can lead to a variety of complications, including misalignment of the permanent teeth, which can affect the child's bite and overall oral health.

In your case, where a primary tooth has been treated for decay but is now showing signs of instability or poor condition, it is essential to consult with a pediatric dentist. The dentist will evaluate the tooth's health and the surrounding teeth to determine the best course of action. If the primary tooth is deemed unsalvageable, it may need to be extracted. However, if it can be preserved, the dentist may recommend treatments such as a crown or filling to maintain its structure and function.

One of the primary concerns with keeping a decayed primary tooth is the potential for infection. If the tooth is compromised, bacteria can enter the pulp, leading to an abscess, which can cause pain and further complications. Additionally, if the tooth is lost too early, the adjacent teeth may drift into the space, leading to crowding or misalignment of the permanent teeth when they eventually erupt. This misalignment can necessitate orthodontic treatment later on, which can be more complex and costly.

In some cases, a space maintainer may be recommended if a primary tooth is lost before the permanent tooth is ready to erupt. This device helps to hold the space open, allowing the permanent tooth to come in properly. Space maintainers can be fixed or removable, and they are typically well-tolerated by children. While there may be some initial discomfort, they are generally not painful.

As for your concern about the gap between the primary tooth and the adjacent permanent tooth, it is essential to understand that the size of the gap can change based on various factors, including the natural development of the teeth and the treatment provided. If the gap has increased significantly after the filling, it may indicate that the primary tooth is not stable, and further evaluation is necessary.

In conclusion, it is crucial to have a thorough examination by a pediatric dentist to assess the condition of the primary tooth and the surrounding teeth. If the primary tooth can be preserved, it is generally advisable to do so to maintain proper alignment and function. If it cannot be saved, appropriate measures, such as extraction and the use of a space maintainer, should be considered to prevent future dental issues. Regular dental check-ups are essential for monitoring your child's dental health and addressing any concerns as they arise.
