Can Your Mouth Reject An Implant?

Jun 24, 2024

There is no doubt that Dental Implants are an excellent method to replace your missing teeth, but have you ever wondered: Can your mouth replace an implant? Despite a high success rate of around 98%, there is still a 2 % chance that your mouth can reject an implant.

Let us explore the question: Can your mouth reject an implant? Find out the reason for rejection and how implant rejection can be prevented.

What are Dental Implants?

Dental implants act as artificial tooth roots that are made from biocompatible materials such as titanium. They are inserted into the jawbone during a surgical procedure to serve as a strong base for new teeth. Dental implants firmly anchor when they bond with the jawbone in a process called osseointegration. This allows them to support different dental appliances like crowns, bridges, or dentures. These implants function and look like natural teeth and give those with missing teeth the freedom to eat, talk, and smile with confidence.

What are Dental Implants made up of? 

Dental implants consist of three main components:

  1. The Titanium Implant
  2. The Abutment
  3. The Crown or Replacement Tooth

While dental implants are reliable, there is a slight risk of failure at each stage of the process. The titanium material used in most implants is highly compatible with the body, but in rare cases, patients may develop allergies or experience rejection. Some complications can also slow down the natural biological integration process.

What are the factors that cause the mouth to reject the Implant?

While dental implants are generally successful, certain factors can increase the risk of rejection:

Improper Aftercare 

Proper aftercare is necessary for the success of a dental implant. One must not neglect oral hygiene as it can lead to infections and implant failure. It is essential to:

  • Brush your teeth at least twice a day.
  • Use an alcohol-free antibacterial mouthwash.
  • Follow your dentist’s post-operative care instructions.


Smoking is an important factor that causes implant failure. The chemicals present in cigarettes slow down the healing process and increase the likelihood of infections. If you are considering dental implants, it is advisable to quit smoking before and after the procedure to ensure optimal healing.

Bruxism (Teeth Grinding)

Bruxism puts excessive pressure on the dental implant which causes complications. This condition can weaken the jawbone and affect the stability of the implant. If you suffer from bruxism, consult the dentist if you can use a night guard to protect your implant and natural teeth.

Gum Disease 

Periodontitis, or gum disease, can damage the gum and bone around the implant, leading to failure. Maintaining basic oral hygiene and regular dental check-ups can prevent gum disease and ensure the longevity of your implant.


Bone density issues, such as osteoporosis, affect the ability of the implant to integrate with the jawbone. If you have a condition that impacts bone health, discuss it with your dentist to determine the best course of action.

How can your mouth reject an Implant?

Although the chances of your mouth rejecting an implant are comparatively low, it is not entirely impossible. For instance, If you are allergic to titanium, the material causes adverse reactions such as bone loss and hypersensitivity.

Look out for the following reactions that occur when your mouth rejects an implant:

  • Unnatural redness
  • Swelling and/or pain
  • Bone loss in the areas near the Implant
  • Itchiness around the implant area
  • Loose Implant: Your oral surgeon or dentist will notice this issue before you do, but if you consistently feel the Implant is moving, it is a sign of implant failure.

How can you prevent Implant Rejection? 

To minimize the risk of implant rejection, follow these guidelines:

  • Maintain Good Oral Hygiene: Brush and floss daily, and use an antibacterial mouthwash.
  • Avoid Smoking: Quit smoking to improve healing and reduce the risk of infection.
  • Address Bruxism: Use a night guard if you grind your teeth.
  • Regular Dental Visits: Schedule regular oral check-ups and dental cleanings with your dentist.
  • Healthy Lifestyle: Maintain a balanced diet and manage underlying health conditions that could affect your implant.
