Dental bridges do more than just fill gaps in your smile. They also restore your ability to chew and speak properly, and they stop your remaining teeth from shifting out of place.
These prosthetic devices can last anywhere from 5 to 15 years, or even longer with the right care. But how long do tooth bridges last, really? A few things impact the answer, including the type of bridge you have, your oral hygiene habits, your diet, and how often you see your dentist.
This article will cover the different types of bridges, factors that influence their lifespan, tips for keeping them in good shape, and signs that it might be time for a replacement.
Understanding Dental Bridges and Their Types
A dental bridge is a non-removable dental appliance that fills in the gap left by a missing tooth. Bridges are typically anchored to the teeth on either side of the gap, or they may be attached to dental implants.
A dental bridge consists of a pontic, or artificial tooth, and abutments, which are crowns that fit over the teeth that support the bridge.
Bridges improve your smile and prevent your other teeth from drifting out of position. They also help you chew properly and maintain the shape of your face. A bridge can also ensure that your bite is correct and prevent the teeth opposite the gap from over-erupting.
There are several types of bridges:
- Traditional bridges are supported by crowns fitted over the teeth next to the gap. With proper care, these can last 10 to 15 years.
- Cantilever bridges are supported by a crown on just one tooth. These may only last 5 to 10 years because they’re supported by just one tooth.
- Maryland bridges are attached to the adjacent teeth with metal or porcelain “wings” that are bonded to the backs of those teeth. These tend to last 5 to 10 years because the bonding can weaken over time.
- Implant-supported bridges are supported by dental implants. These bridges can last 15 years or longer and are considered the most durable option.
Factors Affecting the Lifespan of Dental Bridges
How long your bridge lasts depends on a few things, including how well you take care of it.
Oral Hygiene: The Foundation of Bridge Longevity
Diligent oral hygiene is critical for keeping your bridge healthy. If plaque and bacteria build up around the bridge, you could get decay and gum disease, which can compromise the teeth that support the bridge.
Keep the bridge clean by brushing twice a day and flossing every day, and consider using interdental brushes. Floss carefully around the bridge and under the pontic to remove any trapped bits of food. An antimicrobial mouthwash can also help by killing bacteria in your mouth.
Diet: Fueling (or Foiling) Bridge Durability
What you eat can also affect how long your bridge lasts and how healthy your supporting teeth remain. Avoid hard and sticky foods, as these can damage or even loosen the bridge.
It’s also a good idea to eat a balanced diet with plenty of nutrients that support oral health, such as calcium, vitamins A and C, and lean protein.
Regular Dental Check-ups: Early Detection is Key
You should see your dentist regularly for professional cleanings and to catch any problems early. Your dentist will check the integrity of the bridge and look for signs of decay, gum disease, or loosening.
Lifestyle Choices: Smoking and Alcohol
Smoking and excessive alcohol consumption are both bad for your oral health and can shorten the lifespan of your bridge.
How to make your dental bridge last
A dental bridge can last for a decade or longer if you take good care of it. Here’s how:
- Brush and floss every day. Pay special attention to cleaning around the bridge. You may want to use interdental brushes and picks to get into hard-to-reach spots.
- Watch what you eat. Avoid chewing on hard, sticky, or chewy foods that could damage or dislodge the bridge. That means saying no to hard candies, ice, nuts, and overly chewy sweets.
- Use fluoride toothpaste. Fluoride strengthens your teeth and protects them from decay. Your dentist might also recommend an antimicrobial mouthwash.
- See your dentist regularly. Regular check-ups and cleanings are essential for maintaining the health of your bridge and the surrounding teeth. Aim for twice a year.
- Protect against grinding. If you grind your teeth at night (bruxism), ask your dentist about a nightguard to protect your bridge from excessive force.
When does a bridge need to be replaced?
Even with good care, dental bridges eventually wear out and need to be replaced. Here are some signs that your bridge might need attention:
- Wear and tear
- Loosening
- Gum recession around the bridge
- Pain that doesn’t go away
- Changes in your bite
- Inflammation around the bridge
- Damage to the bridge
If you notice any of these problems, it’s important to contact your dentist right away. Putting off bridge replacement can damage the teeth that support the bridge, lead to gum disease, and cause problems with your bite.
If you need a bridge replaced, your dentist might also talk to you about other options, such as dental implants, partial dentures, or full dentures. Dental implants last longer than bridges. Partial and full dentures are other methods for replacing missing teeth.
The Bottom Line
If you want your dental bridge to last as long as possible, you’ll need to take good care of it. That means practicing excellent oral hygiene, eating a healthy diet, seeing your dentist regularly, and making smart lifestyle choices.
If you notice any problems with your bridge, like sensitivity, looseness, or a change in how it feels, be sure to contact your dentist right away.
With proper care and attention, a dental bridge can be a great way to restore your smile and improve your overall oral health for many years to come.
