Why Would a Dental Implant Fail?

July 20, 2023

Although dental implants have a very high success rate, it is possible for a dental implant to fail. The success of a dental implant procedure depends heavily on the placement of the implant and the final restoration, a dental crown, that is placed on the end.

So why would a dental implant fail? Here are a few reasons why a dental implant may never heal properly or may fail months or years after the procedure.

There Is Not Enough Bone in the Jaw

Patients must have enough bone in the jaw to properly support the implant. Without enough bone or poor bone quality, a dental implant is more likely to fail. This is because the implant was never properly supported in the first place and is, therefore, more prone to shifting or inflammation over time.

If you lack bone in your jaw because you have been missing teeth for some time, a bone graft procedure is necessary prior to a dental implant placement to ensure you have the best chance of a successful implant placement and healing process. Otherwise, your dental implant procedure will ultimately not be successful [1].

You Smoke or Chew Tobacco

People who smoke or use tobacco products have a much higher failure rate for their dental implants than those who don’t [2]. These patients have a higher chance of complications after the procedure, including infection or implant failure.

In addition, patients who use tobacco can also compromise the tissue around the implant, which may cause bone loss even if they have previously had a bone graft.

Another important factor in implant failure among patients who smoke or chew tobacco is periodontal disease, also called gum disease. Patients who use tobacco are at higher risk of gum disease, which can ultimately lead to implant failure by damaging the connective tissue around the implant.

The Placement of the Implant

The placement of a dental implant is critical to a successful restoration, and complications from dental implant placement are one of the biggest challenges with this procedure [3]. Although dental implants can replace almost any missing tooth, they must be properly placed with an appropriately sized and shaped restoration for the tooth that has been lost.

Placement is so important because, unlike other restorations, the implant replaces your tooth’s root. Your tooth’s root is responsible for supporting the crown of the tooth for proper chewing and biting. Without appropriate placement, the implant can cause irritation, inflammation, and even infection.

A properly placed dental implant should not hurt or be uncomfortable. By prioritizing the position of the implant, your oral surgeon can maximize your chances of a successful implant procedure.

Working with an oral healthcare professional, such as a prosthodontist, who is experienced in placing dental implants can help ensure you have the appropriate placement and restoration for a comfortable, long-lasting implant.

You Have Gum Disease

Patients with gum disease must be successfully treated before qualifying for dental implants [4]. Since gum disease damages both gum tissue and the bone that helps anchor the teeth in place, it’s imperative to have healthy gums before getting a dental implant.

However, if you develop gum disease after getting a dental implant, your implant may eventually fail, even if it was placed perfectly. Taking care of your teeth and gums before and after implant placement is essential to ensure a long-lasting restoration and a beautiful smile.

Ensure Your Best Chance for Implant Success

Working with an experienced professional, taking excellent care of your teeth, avoiding tobacco products, and treating gum disease can all help you have your best chance for implant success.
