All You Need to Know About PFM Dental Crowns

Dental crowns have been around since ancient times as a way to restore the shape and function of teeth that have been damaged or lost. In modern dentistry, there are several types of dental crowns, such as ceramic, metal, and porcelain fused to metal (PFM) crowns. In this article, we'll focus on PFM dental crowns and provide all the details you need to know about them, including their uses, benefits, and drawbacks.

1. What are PFM dental crowns?
PFM dental crowns are a type of dental crown that consists of a metal substructure covered with a layer of porcelain. The metal substructure provides strength and durability, while the porcelain layer gives the crown a more natural and aesthetically pleasing appearance. PFM crowns are commonly used for molars and premolars because they can withstand the chewing forces and offer good longevity.
2. Why choose PFM dental crowns?
PFM dental crowns have several benefits that make them a popular choice for many patients. Firstly, they offer excellent durability and can last for many years with proper care. Secondly, they provide a natural-looking appearance that can match the color and shape of surrounding teeth. Thirdly, they are more affordable than all-ceramic crowns, making them a great option for budget-conscious patients.
3. How are PFM dental crowns placed?
The process of getting a PFM dental crown usually requires two dental visits. In the first visit, the dentist will prepare the tooth by removing any damaged or decayed parts and shaping it to receive the crown. Then, the dentist will take an impression of the tooth to create a model that will be used to make the crown. This process may take up to two weeks, during which the patient may receive a temporary crown. In the second visit, the dentist will remove the temporary crown and place the permanent PFM crown onto the prepared tooth using dental cement.
4. What are the drawbacks of PFM dental crowns?
One of the drawbacks of PFM dental crowns is that the metal substructure may cause the gumline to appear dark or discolored over time. This can be a concern for patients who want a completely natural-looking smile. Another potential drawback is that the porcelain layer may chip or fracture if subjected to excessive force, requiring replacement or repair. Finally, some patients may experience sensitivity to hot or cold temperatures due to the metal substructure.
In conclusion, PFM dental crowns are a reliable and affordable option for restoring the shape and function of damaged teeth. They offer good durability, natural-looking appearance, and can withstand the chewing forces of molars and premolars. However, they do have some potential drawbacks, such as gumline discoloration, porcelain chipping, and hot or cold sensitivity. If you're considering getting PFM dental crowns, talk to your dentist to determine whether they're the right choice for your dental needs.
