What are the main components of a PFM crown?

A PFM crown (Porcelain-Fused-to-Metal crown) consists of two main components that work together to provide strength and aesthetics:

This is the inner layer of the crown made from a metal alloy, which can include base metals (like nickel-chromium or cobalt-chromium) or noble metals (like gold or palladium).

The metal framework provides the structural support, ensuring durability and the ability to withstand strong chewing forces. It also helps the crown fit securely over the prepared tooth.

The outer covering of the crown is made of tooth-colored porcelain that is fused to the metal substructure. This layer gives the crown a natural appearance, allowing it to blend seamlessly with adjacent teeth.

The porcelain can be color-matched to the patient’s natural tooth shade for improved aesthetics.

PFM crowns a popular choice in dental restorations, especially for posterior teeth, where both strength and appearance are important. The combination of metal for strength and porcelain for looks provides a well-balanced solution for restoring damaged or decayed teeth. Read more…..

How has medical cannabis helped your life?

  Medical cannabis has provided effective relief without the harsh side effects of opioids. People suffering from anxiety, PTSD, or depression have found cannabis especially CBD-rich formulations to help calm the mind, reduce intrusive thoughts, and promote emotional balance, often when traditional medications failed or caused adverse effects. Cancer patients have used cannabis to manage chemotherapy-induced nausea, stimulate appetite, and relieve pain, improving their strength and outlook during grueling treatments. Medical cannabis has shown remarkable results in reducing seizure frequency and severity. These improvements often lead to a greater sense of autonomy, peace, and hope. Medical cannabis empowers individuals to reclaim control over their health, blending nature with science in a way that respects both the body’s complexity and the power of plant-based healing offering more than just symptom relief, but a renewed sense of life.  Read more……

What’s the difference between CBD and medical marijuana?

  The difference between CBD and medical marijuana lies primarily in their composition, effects, and legal classification, and at   Greenlight Wellness Export , we help patients understand these distinctions to make informed health decisions.

It is typically derived from  hemp , a variety of cannabis with low THC (tetrahydrocannabinol) content, and is used to manage conditions like anxiety, inflammation, epilepsy, and chronic pain without altering mental clarity.
