Can Temporary Dentures Be Worn Long-Term? Material and Comfort Issues

Can temporary dentures be worn for an extended period?

Previously, due to gum recession around my front dental prosthesis, my natural teeth became exposed, so I decided to redo it.
However, after the procedure, the prosthesis kept hitting my lower lip, so I had to switch to another clinic.
This time, I only got a temporary denture, which I was also dissatisfied with.
Eventually, I found a doctor who simply adjusted the temporary denture, and it felt much better.
However, he was unwilling to redo it, stating that it was fine as it is.
I would like to ask if temporary dentures are made of plastic? Is this material suitable for long-term use? When I eat hot food, I feel like it contracts and puts pressure on the roots of my teeth; is this just an illusion? Additionally, I need to have my second molar extracted due to a root fracture.
Will this cause my other teeth to become loose? Thank you!

1.
It may be due to the edges of the dentures being too long, putting pressure on the gums, and the temporary dentures being made of insufficiently durable resin, which could lead to complete fracture upon biting.
It is recommended to replace them with permanent crowns.
2.
Simply extracting the second molar will not cause other teeth to become loose.

More Info

Temporary dentures, often referred to as interim or provisional dentures, are typically made from acrylic resin or other types of plastic materials. These materials are chosen for their ease of fabrication and affordability, making them suitable for short-term use while a more permanent solution is being prepared. However, there are several important considerations regarding their long-term wear and the potential risks associated with their use.

Material and Comfort Issues
1. Material Composition: As mentioned, temporary dentures are usually made from acrylic resin. This material is lightweight and can be easily adjusted, which is beneficial during the transitional phase. However, acrylic is not as durable as the materials used in permanent dentures, such as porcelain or high-strength ceramics. Over time, acrylic can wear down, stain, or become brittle, leading to cracks or breaks.

2. Long-Term Use: While temporary dentures can be worn for extended periods, they are not designed for long-term use. Prolonged wear can lead to discomfort, as the fit may change due to gum shrinkage or bone resorption, which often occurs after tooth extraction. This can result in pressure points, sore spots, and even gum irritation. Additionally, the material may not withstand the forces of chewing as effectively as permanent dentures, leading to further complications.

3. Heat Sensitivity: You mentioned feeling a sensation of pressure when consuming hot foods. This could be due to the thermal expansion properties of the acrylic material. Acrylic can expand and contract with temperature changes, which may create a feeling of tightness or discomfort against the underlying gums or teeth. This sensation is not merely a psychological effect; it can be a genuine response to the material's properties.

Impact of Tooth Extraction on Adjacent Teeth
Regarding your concern about the extraction of your second molar due to a cracked root, it is generally understood that removing a tooth does not directly cause adjacent teeth to become loose. However, there are several factors to consider:
1. Bone Support: The teeth are supported by the surrounding bone structure. When a tooth is extracted, the bone that once supported it may begin to resorb over time. This can affect the stability of neighboring teeth, especially if they were already compromised.

2. Shifting of Teeth: After an extraction, the adjacent teeth may shift into the space left by the removed tooth. This movement can lead to misalignment and may cause some teeth to feel loose or unstable.

3. Gum Health: The health of your gums plays a crucial role in the stability of your teeth. If the extraction site becomes infected or if there is significant gum recession, this could impact the support for adjacent teeth.

Recommendations
1. Consultation with a Dentist: It is crucial to maintain regular check-ups with your dentist, especially after an extraction. They can monitor the health of your gums and the stability of your remaining teeth.

2. Consider Permanent Solutions: If you are experiencing discomfort with your temporary dentures, it may be worthwhile to discuss options for permanent dentures or implants with your dentist. Permanent solutions are designed to provide better comfort, fit, and functionality.

3. Oral Hygiene: Maintaining excellent oral hygiene is essential, particularly after tooth extractions. This will help prevent infections and promote healing, which is vital for the stability of your remaining teeth.

In conclusion, while temporary dentures can serve as a stopgap solution, they are not ideal for long-term use due to their material properties and the potential for discomfort. It is advisable to seek a permanent solution to ensure both comfort and oral health.
