What are Porcelain Fused to Metal (PFM) Restorations?

PFM restorations

If you are in need of a dental restoration, you may be wondering what type of restoration is right for you. There are many different types of restorations available, and one popular option is porcelain fused to metal (PFM) restorations. In this blog post, we will discuss what PFM restorations are, how they are made, and the benefits they offer. We will also provide some tips on how to care for your PFM restoration.

PFM restorations are dental restorations that are made of porcelain and metal. The porcelain exterior is fused to the metal interior, which gives it a strong and durable structure. There are different types of metals that can be used such as base metal alloys, titanium alloys, or gold alloys. With PFM restorations, you get the durability of a metal restoration with the natural appearance of a porcelain restoration. Both crowns and bridges can be fabricated using the PFM method.

The process of getting a PFM crown or bridge is much like the process used for other types of crowns and bridges. First, your dentist will remove any decayed or damaged tissue. Then, they will reshape the remaining tissue to accommodate the restoration. For a crown, only a single tooth will be prepared. For a bridge, two teeth will be prepared on either side of the gap. Then your dentist will take an impression of your teeth, which will be used to create a mold in the dental lab.

PFM crowns and bridges are made in a dental lab according to this dental impression. The porcelain is molded over a metal form, and then the two are fused together in a kiln. The mold will be used to create your PFM restoration, which will be custom-fit to your mouth. Once the restoration is complete, the dentist will place it on your tooth and secure it in place.

Benefits of PFM Restorations

PFM restorations offer several benefits over other types of restorations, including:

A long lifespan

When properly cared for, PFM restorations can last for up to 20 years, which is significantly longer than other types of restorations. On average, most PFM restorations last for about 10-15 years.

A natural appearance

The porcelain on a PFM restoration can be matched to the color of your teeth, so it will blend in seamlessly with your smile and maintain a natural appearance.


Since metal is used for the interior layer of the restoration, PFM restorations are strong and durable. This means they can withstand biting and chewing forces, and are ideal for use towards the back of the mouth. They can also be used for people who grind their teeth since they are more resistant to cracks and chips.

Resistance to staining

The porcelain on a PFM restoration is resistant to staining, so it will stay looking clean and white for longer. However, it is still important to practice good oral hygiene since the surrounding teeth can still become stained.

Caring for a PFM Restoration

Once you have a PFM restoration, it is important to make sure that you are properly caring for it to keep it in good condition. Here are some tips on how to care for your PFM restoration:

Brush and floss regularly

You should brush your teeth at least twice a day and floss at least once a day. Be sure to gently brush and floss around the base of the restoration where it meets your gums.

Use non-abrasive toothpaste

Toothpaste that is abrasive can damage the porcelain on your restoration. Use a toothpaste that is designed for sensitive teeth, and avoid using whitening toothpastes. You can ask your dentist for recommendations if you are not sure which toothpaste to use.

Avoid biting nails and hard objects

Biting nails or chewing on hard objects can cause chips or cracks in your restoration. Be careful when eating hard foods, and avoid using your teeth as tools. Although PFM restorations are strong, they can still be damaged.

See your dentist regularly

It is important to see your dentist for regular checkups and cleanings. During these appointments, they will inspect your restoration for any damage or wear.
