Why Some Dental Implants Fail?

Did you know that 6.4% of Canadians have no teeth? While you may not necessarily be missing all of your teeth, you might have some that aren’t present anymore. In that case, dental implants may be a good choice for replacements.

However, like many other things in life, these may not always be 100% successful.

In this article, we’ll discuss why dental implants fail and what you can do to increase your chances of having successful ones.

Why Dental Implants Fail

It’s rare, but dental implants can fail sometimes. Let’s explore all the ways it can happen.

The main success criteria in implant dentistry is case selection. While there is no absolute contraindication for dental implant but there is higher failure rate in people who are smoker, medically compromised like uncontrolled diabetes or under active chemo or radiotherapy.

Poor Dental Implant Hygiene

Dental implant does not get cavity but they get gum disease and infection. In most cases, they fall out because of infection which is called peri-implantitis. This is where infection happens not only on the implant, but also on your gums. If it gets bad enough, the infections can lead to bone loss.

The best way to combat this is to practice the best dental hygiene you can. This includes brushing at least twice a day and flossing as well.


Dental implants may also fail because of bruxism. This is where you grind your teeth, which can happen while you’re awake or asleep. In most cases, people have bruxism because they’re going through high levels of stress, which can manifest in teeth grinding while they’re sleeping.

This can be resolved by managing your stress, adjusting your medications, and using mouth guards that are special-made for your mouth. Mouth guards can protect your teeth and implants under uncontrolled functional forces.

Bad Health

If your overall health isn’t so great, this can cause dental implants to fail. For instance, if you have chronic health conditions such as diabetes, osteoporosis, periodontitis, or cancer, these can all significantly impact the success rate of your dental implants.

This is why it’s important to discuss your overall health in detail with your dentist so together, you can figure out if dental implants are right for your situation.

Bad Placement

Implants are placed with experienced dental surgeons or periodontists have shown higher success rate. Implant site evaluation using Cone Bean CT scan is crucial for accurate implant treatment planning. Prosthodontist have gone through extensive implant treatment planning. Implants are mis/mal placed will fail after couple of years. As the implants fails, it will destroy the supporting jaw bone too. Replacement of the failed implant is very difficult and in some cases is impossible.

For a dental implant to work well, you must have enough jawbone for it to anchor onto. If there is insufficient jawbone, then the implant might fail.

Because of this, it’s vital you get an experienced and skilled specialist dentist to plan and insert your dental implant.

Get Quality Dental Implants

While there’s a slight chance for them to fail, you can expect them to last you a long time if you’re vigilant about oral care.
