Dental crowns are also known as “caps” or covers placed over affected teeth to strengthen them and improve the aesthetics of your smile. Dental crowns restore the shape and size of a tooth, allowing them to function like before. This article will answer in detail some of the most common questions regarding dental crowns, including “how long do dental crowns last,” “difference between a cap and a crown,” “best dental crown material,” and “does getting a crown hurt.” 

If you have a weakened, chipped, cracked, or worn tooth, you might need a dental crown. Other cases when a tooth crown might be needed is after a root canal treatment or due to excessively large tooth decay or cavities. A crown is placed on the restored tooth after a root canal to protect it from further damage. If you have large cavities that cannot be treated with a filling, you’ll need a porcelain, ceramic, or metal crown or the one that is made from the material your dentist recommends.

How Long Does A Tooth Crown Last

The average lifespan of dental porcelain crowns is between 5 to 15 years. How long do porcelain crowns last depend on the way you maintain your oral hygiene, your daily routine that includes foods and drinks you consume, the way you use your teeth, for example, if you have a habit of nail-biting, and the strength of your dental crown.

If your porcelain crowns experience daily wear and tear, they are more likely to lose their strength. If you don’t want to reinvest in getting a new crown and want it to last longer, you’ll have to avoid certain habits such as grinding your teeth, chewing pen, nuts, or ice, biting your nails, and opening packages using your teeth. These habits are bad for your porcelain crowns as well as your teeth and can weaken them.

With proper care and a healthy lifestyle, your permanent porcelain crowns can even last between 25 to 30 years. One important thing to remember is to keep the tooth under the crown healthy and strong. Not doing so can result in tooth decay under the crown, and you will need treatment that includes the removal of a dental crown.

How Long Do Crowns On Front Teeth Last

In many cases, the dental porcelain crowns applied on the front tooth will last for at least 15 years. Depending on the quality, some crowns can even last up to thirty years. Insurance companies that provide dental cover will pay for dental crowns replacement after 5 years of the first installation. If a dental expert correctly installed your dental crown and you take good care of your front teeth crowns, it should last for a lifetime.

How Long Does A Crown Take

Usually, it takes two dental visits to get a crown that can be weeks apart. On the first visit, your dentist will remove dental decay from the tooth and take an impression to make a temporary crown. The temporary crown will be ready in an hour or two and will be placed on the same day. Your temporary crown will be removed in your next visit, and you’ll receive a permanent tooth cap.

What Is The Difference Between A Cap And A Crown?

Often, people hear things like ‘dental crowns’ or ‘dental caps’ and ask if there’s any difference between the two. To clear up your mind, let’s get it straight. A dental crown and a dental cap are both the same things, and no difference lies between them.

How Do You Know When A Crown Needs To Be Replaced?

The dental crowns you get today are very durable, but they may need repairs or replacement after around 15 years. Some cases clearly indicate that your tooth crown needs a replacement, such as if your crown broke off at the gum line or is severely cracked. Other times you may have a loose crown, and you don’t pay much attention to it. But note that you may end up with pain and discomfort if you ignore the problems with your dental crown.

Here are some signs that indicate your dental crown needs a replacement.

Loose Dental Crown

When a dental crown is first placed, it should firmly fit but, if you get a wobbly feeling, know that your dental crown is loose. Some other loose crown symptoms include hot or cold sensitivity and food debris clinging to the gum line.

So can a loose crown be repaired?
It’s important to fix a loose dental crown, or it will completely come off the tooth. All you have to do is go to your dentist, who will inspect your crown’s condition and provide appropriate treatment.

Receding Gums

If you have receding gums, the gum tissue will move away from the tooth with a crown. In such a case, you’ll need periodontal treatment and a crown replacement.

Old Crown

If your crowns are very old, it’s natural for them to have wear and tear. Depending on the damage to your dental crown, it may be repaired by your dentist or may need complete removal.

Dental Crown Replacement Procedure

Replacing a crown is very similar to when you had the first fitting. After the numbing procedure, your treatment will begin. The old crown will be removed, and the tooth underneath will be examined by your dentist. Further treatment will depend on your oral condition. Replacing crowns on the front teeth is similar but can be a little easier than replacing those on the molars.

Metal Crown Vs Porcelain Crown

Porcelain crowns are a choice for most people because they promise the best aesthetics and functionality. Since they are porcelain made, they look very similar to natural teeth, and they can completely mimic the color and shape of your tooth. Ceramic or porcelain crowns can cost around $800-$3000 per tooth.

Before porcelain caps came to the market, metal crowns were the ones to provide a covering for damaged teeth or to restore a tooth after a root canal treatment. Metal crown or ‘silver teeth cap’ is made from chromium, nickel, or gold alloy. These silver tooth caps are strong and durable, but they are not much pleasing as porcelain crowns. When a person wearing silver caps on the teeth laughs or smiles, it may look weird. The price of silver teeth caps is between $800-$1400 per tooth.

Porcelain caps are more favorable in terms of aesthetics vs metal crowns.

Types of porcelain crown

Ceramic (porcelain crowns)

Porcelain crowns can be regarded as the best dental crown material for front teeth. They blend perfectly with the natural color of the tooth and restores a front-teeth smile. You can also call them white cap for teeth.

Porcelain-Fused-to-Metal Crown(PFM)

These teeth caps are very durable and have a long life span, and strongly bond to the teeth.

Base-Metal Alloy

These are the strongest teeth caps, and you don’t have to worry about any fractures or wear and tear.

Gold Alloy

Just like base-metal alloy, these can be regarded as the best material for dental crowns in terms of strength.


These are known for strength and are a natural-looking option—a low-cost alternative.

Ceramic Crown Vs Porcelain Crown

If you don’t know which crown is best for your condition, you should learn more about porcelain vs ceramic crowns. You may find it amazing that the materials of both porcelain and ceramic crowns are made of dental ceramics and dental porcelain. This simply means that both can provide you same results. However, there’s a difference in their making. Ceramic crowns include some porcelain, whereas the porcelain crowns include only dental porcelain. Porcelain and ceramic crowns help restore front teeth as they can amazingly blend with the natural color of your tooth.

Why Does My Dental Crown Hurt

Here are some common reasons why you may experience a dental crown toothache.

Cavity Under Crown

Many people think that one cannot get a cavity under a dental crown. But the reality is the opposite. Because the dental crown has an alive tooth under it, there is a possibility that the cavity can grow at the edge of the crown and tooth. When a dental plaque builds up, it forms a cavity that leads to tooth decay growth under the crowns. The symptoms of tooth decay under a crown include rotten or black teeth under the crown.

Chipped Dental Crown

If you have a chipped or cracked permanent dental crown, you may experience slight pain or discomfort while eating or even without that. If you have a loose tooth cap, or it has cracked or broken off, immediately set an appointment with your dentist.

Loose or Ill Fitted Crown on Tooth

When you have a new crown, the biting surface of your tooth will change. If your permanent crown is not properly fitted and is slightly high or tall, you will experience pain while eating or chewing. If you have toothache when biting down with a dental crown, you should consult your dentist. Your crown may need a little adjustment.
