What are the disadvantages of removable dentures

Dental problems are a common phenomenon in our lives, especially for people who like to eat sweets, which are particularly prone to dental problems, which will seriously affect our chewing of food. However, there are many types of dentures that I usually install, among which removable dentures are the most common, but they also have certain disadvantages. We can understand them and wear dentures that suit us according to our own situation. Let’s learn about the disadvantages of removable dentures.

What are the disadvantages of removable dentures?

Removable dentures often present various problems due to their diversity in design and restoration as well as their mobility.

Pain is the most common problem, including abutment tooth pain and soft tissue pain. Abutment tooth pain is mostly caused by excessive force or lateral external force from the clasp. Soft tissue pain is mostly caused by the base edge being too long or too sharp, small tumors on the base tissue surface, etc. It can also be caused by the presence of bone tips or bone protrusions or bone ridges on the alveolar ridge, which form tissue concave depressions, thin covering mucosa, dentures squeezing the base downward, and sharp ridges being worn.

Poor retention is also a common problem, which is mainly manifested as: ① Bounce, the clasp does not enter the concave area of ​​the abutment tooth; ② Tilting, swinging, and up and down movement. The reason is that the clasp body does not fit the base, the indirect retainer is placed in an improper position, the occlusal support, the clasp forms a fulcrum on the tooth surface, and the clasp has no retention force; ③ The base and tissue are not in close fit, and the edge is not well sealed; ④ The crown of the abutment tooth is small, or conical, resulting in poor retention; ⑤ The artificial tooth is improperly arranged, and it tilts during occlusion; ⑥ The edge of the base is too long, affecting soft tissue activity.

Difficulty in wearing and removing dentures: The clasp is too tight, the base is close to the tooth surface, the base in the undercut area is not sufficiently cushioned, and the patient does not understand the direction and method of wearing and removing the dentures, all of which can cause difficulty in wearing and removing the dentures.

Food impaction: Food impaction and retention between the denture and tissue, the original base not fitting tightly against the tissue, the clasp not fitting well against the abutment tooth, and there is a gap between the base and the natural tooth can all cause food impaction.

Unclear pronunciation: After wearing dentures, the oral space is reduced, the tongue movement is restricted, and there is temporary discomfort, which often causes pronunciation difficulties. You can get used to it after a period of training.

Biting the cheek and tongue mucosa: If the upper and lower posterior teeth cover too little, it is easy to bite the cheek; if the mandibular posterior teeth are arranged towards the tongue or the occlusal plane is too low, it is easy to bite the tongue.

Nausea and increased saliva: Wearing maxillary removable dentures can cause nausea due to excessive stretching or thickness of the posterior edge of the base, or the lack of fit between the posterior edge of the base and the mucosa, resulting in saliva stimulation between the two. Saliva is mostly caused by unfamiliarity.

Appearance issues: If the patient is not satisfied with the appearance after wearing the lens, the teeth or other parts can be adjusted.

The above is an introduction to the disadvantages of removable dentures. After understanding it, I hope that you can make choices based on your own situation when you have dental problems. In addition, when wearing dentures, you must pay attention to maintaining good oral hygiene. It is best to remove the dentures when sleeping at night.
