How long do dental crowns and bridges last?

Those of you who already have one may be asking yourself how long a crown or bridge will last. Will it last a few years, last a lifetime or will it break down? And if it does, what is the reason? Of course, all these questions will be answered in the easiest and most understandable way possible.

What Are Dental Crowns and Bridges?

Before we talk about how long they last, let’s quickly understand what they are.

Dental crown

A dental crown is a cap that covers a damaged or broken tooth. Think of it like a little helmet for your tooth. If your tooth is broken, weak or after a root canal, a crown is put on to protect it. It looks and feels like a real tooth.

Crowns are made from different materials, such as:

1. Porcelain (looks like your natural tooth)
2. Metal (very strong)
3. Zirconia (very strong and white)
4. Porcelain fused with metal (a mixture of the two)

Dental bridge

A dental bridge is used when one or more teeth are missing. It fills the gap. The bridge is made by joining one or more crowns together. The crowns at the ends are placed on healthy teeth next to the gap. They act as anchors to hold the bridge in place.

In short:

1. Crowns cover damaged teeth.
2. Bridges fill the gap caused by missing teeth.
3. How long do dental crowns last?

How long do dental crowns last?

Generally, the life expectancy of dental crowns is between 10 and 15 years. With ideal care, some crowns can last more than 20 or 25 years.

Life span depends on factors such as:

1. The material of the crown
2. How well you take care of your teeth
3. Your biting and chewing habits
4. If you grind your teeth at night

Lifespan by Crown Type:

1. Metal crowns: 15-25 years (Very strong)
2. Porcelain crowns: 10-15 years (More natural-looking)
3. Zirconia crowns: 15-20+ years (Strong and tooth-colored)
4. Porcelain fused to metal: Around 10-15 years

How long do dental bridges last?

Dental bridges usually last about 5 to 15 years. But again, some people's bridges have lasted even longer.

This depends on:

1. The health of the supporting teeth (the ones holding the bridge in place)
2. How clean you keep the area
3. The type of bridge and the materials used
4. If you bite hard or grind your teeth
5. Like crowns, bridges can last a long time if you take good care of them.

What Makes Crowns and Bridges Last Longer?

You can help your crown or bridge last longer by doing a few simple things every day.

1. Brush and Floss Daily

Even though crowns and bridges are not real teeth, the teeth under them still need care. You can get cavities or gum disease if you don't clean them well.

1. Brush twice a day with a soft toothbrush
2. Floss gently around the crown or under the bridge
3. Consider using a water flosser for easier cleaning

2. Don't Bite Hard Stuff

1. Avoid chewing on:
2. Ice
3. Hard candy
4. Fingernails
5. Pen caps
6. These can crack or loosen your crown or bridge.

3. Wear a Night Guard (If Needed)

If you grind your teeth while you sleep (called bruxism), ask your dentist for a night guard. Grinding can wear down or break your crown or bridge.

4. Visit the Dentist Regularly

Seeing your dentist every 6 months helps spot problems early. They can check if your crown or bridge still fits well and clean areas you can't reach.

What Happens If You Don’t Take Care of Them?

If you ignore your crown or bridge, these problems can happen:

Cavities under the crown

Even though the crown doesn't decay, the tooth under it can still get a cavity.

Gum problems

Not cleaning around the crown or bridge can lead to red, swollen gums and gum disease.

Loose or broken crown/bridge

Crowns and bridges are firm but not unbreakable. If they loosen, bacteria can get in.

Bad breath or taste

A loose or damaged crown can trap food and bacteria, causing bad breath or a weird taste in your mouth.

Signs Your Crown or Bridge Might Need to Be Replaced

Here are some signs that your crown or bridge may be wearing out:

1. Pain or Sensitivity

If the tooth under the crown starts hurting, it could mean decay or nerve problems.

2. Crown or Bridge Feels Loose

It needs to be checked if it wiggles when you bite or talk.

3. Visible Cracks or Chips

If you see damage, it may no longer protect your tooth adequately.

4. Gum Recession

If your gums are pulling away from the crown or bridge, it can expose the edge of the tooth.

5. Bad Smell or Taste

That could indicate trapped bacteria or infection under the crown or bridge.

If you notice any of these, don't wait. Go to your dentist.

How Much Does It Cost to Replace a Crown or Bridge?

1. Costs can vary depending on the material, dentist, and home.
2. Average Prices (in the U.S.):
3. Crown: $800 to $2,500
4. Bridge: $2,000 to $5,000 or more

Insurance might cover some or most of the cost, especially medically necessary. It's always a good idea to check with your dental insurance provider.

Can a Crown or Bridge Last a Lifetime?

It's possible but not common. Most people will need a replacement at some point.

However, some crowns and bridges have lasted over 25 to 30 years when taken care of properly. The key is daily care and regular dentist visits.

Tips to Make Them Last as Long as Possible

Let's wrap up with a quick checklist:

✅ Brush twice a day

✅ Floss or use a water flosser

✅ Avoid chewing on hard things

✅ Wear a night guard if you grind your teeth

✅ Go for checkups every 6 months

✅ Treat any issues early

Doing these things will help you avoid the need for early replacements and save money in the long run.

Final Thoughts

Dental crowns and bridges are excellent tools to fix your smile and help you chew better. But like anything else, they don't last forever.

• Crowns last around 10 to 15 years—some even longer.
• Bridges usually last 5 to 15 years, depending on how well you care for them.
• The better you care for them, the longer they stay strong and valuable.

So treat your crown or bridge like a real tooth—clean, protect, and visit your dentist on time. That way, your smile will last for many years to come.
