How Long Do Implant Supported Dentures Last?


Dental implants are the most advanced technology available in dentistry for tooth replacement. They provide support for any number of replacement teeth from a single tooth to a full arch.

If you’re considering implant supported dentures, you may be wondering how long they last. Here’s what you can expect. 

What Are Implant Supported Dentures? 

Implant supported dentures refers to a total replacement of an entire arch of teeth that are supported by 4 dental implants. The implants are surgically placed in the jaw bone in strategic locations to provide the best support and to evenly distribute chewing force. A full arch denture is attached to the implants and will remain fixed in place. In many cases implant supported dentures can be placed in a single day or as little as one appointment. They can restore all of the teeth on the upper and lower jaw. 

Average Lifespan of Implant Supported Dentures 

Implant supported dentures are made up of 2 parts, the implants and the denture. The dental implants fuse with the bone in your jaw, forming a solid bond that can last for the rest of your life. The denture portion typically lasts about 10 years before needing to be replaced. Normal wear and tear from chewing can gradually damage the dentures over time. They may last longer than 10 years with excellent care and maintenance. 

Contributing Factors 

The following factors may contribute to the lifespan of your implant supported dentures: 

  • Eating habits. What you eat will make a difference in how quickly your dentures wear out. Frequently chewing on hard candy, nuts, and seeds can cause your dentures to wear down or become damaged. 
  • Teeth grinding. If you grind your teeth at night when you sleep, this habit will cause your dentures to wear down more quickly or develop cracks. 
  • Biting or chewing non-food items. You should never open containers or remove tags with your dentures. You should also avoid chewing on non-food items such as pens, pencils, or your fingernails.
  • Quality of the dentures. The quality of the materials and manufacturing of the dentures will also affect the lifespan. The higher the quality, the more they may cost. But if you get more years of wear out of them, the higher price may be worth it. 

How To Make Your Implant Supported Dentures Last Longer

There are some things you can do to help extend the life of your implant supported dentures: 

  • Practice good oral hygiene. Brush your dentures regularly like you would your natural teeth. You should also use a special brush or water flosser to get the spaces between your dentures and gums clean and free of food particles. 
  • Go to the dentist regularly. It is important to go to the dentist at least every 6 months to have your dentures cleaned and inspected. This allows your dentist to detect any damage that would cause potential problems. 
  • Protect your dentures. If you know that you grind your teeth, you can wear a night guard over your dentures to protect them from the force of clenching your jaw and the pressure it exerts on your dentures. If you play sports it is a good idea to wear a mouthguard to protect your dentures from damage. 

How Do Implant Supported Dentures Compare With Other Types?

Other types of dentures vary in terms of lifespan. Traditional dentures that attach to the gums with suction or adhesives tend to last between 5 and 10 years. This is often due to damage or changes in the shape and structure of the jaw. 

Implant supported dentures are anchored in the jaw with around 6 implants. This makes them more secure which helps them last longer. Implant supported dentures may last up to 20 years before needing to be replaced.
