The main risks of dental implants are infection, failure of the implant to properly fuse with the jawbone, nerve or sinus injury, and gum recession around the implant site, though serious complications are uncommon when implants are placed and maintained correctly. Most patients experience only mild, temporary swelling or discomfort after surgery. At Sola Dental Spa in Staten Island, Dr. Daniel Nejat walks every implant patient through these risks up front so there are no surprises before treatment begins.
Common Side Effects After Surgery
| Side Effect | Typical Duration |
|---|---|
| Swelling | 2 to 3 days |
| Bruising | 1 to 2 weeks |
| Discomfort | 3 to 7 days |
| Minor bleeding | 1 to 2 days |
These effects are normal and generally resolve without complications when you follow your dentist's post operative instructions closely. If swelling or pain worsens after the first few days instead of improving, that is a signal to call your dentist rather than wait it out.
Infection and Other Complications
Infection is uncommon after implant surgery, but it remains one of the more serious risks, since it can interfere with the implant's ability to fuse to the jawbone and, in some cases, lead to implant failure. Watch for increasing pain, swelling that worsens after the first few days, fever, or discharge near the implant site, and contact your dentist promptly if any of these appear. Infections are often treatable with antibiotics, though more advanced cases may require additional procedures such as a bone graft or removal of the implant.
Failure of Osseointegration
Osseointegration is the process by which the jawbone fuses to the titanium implant, and it is what makes an implant stable enough to support a crown long term. This process typically takes several months. If osseointegration does not fully occur, the implant may feel loose or fail to support a restoration, and it may need to be removed and replaced. Bone density, implant placement, and infection all influence whether osseointegration succeeds.
Factors That Raise Your Risk
| Factor | Why It Matters |
|---|---|
| Smoking | Reduces blood flow to the gums and can interfere with healing and osseointegration. |
| Uncontrolled diabetes | Slows healing and raises infection risk. |
| Low bone density | Can prevent the implant from fusing securely, sometimes requiring a bone graft first. |
| Poor placement or alignment | Can lead to bone loss or damage to nearby teeth and structures. |
| Poor oral hygiene | Raises the risk of peri-implantitis, an infection of the tissue around the implant. |
Choosing an Experienced Provider
Implant placement is a surgical procedure, and outcomes are strongly tied to the training and experience of the person planning and placing it. A thorough workup, including imaging to map bone density and the location of nerves and sinuses, is what allows a periodontist to avoid many of the risks described above before surgery ever begins. At Sola Dental Spa, this planning stage is treated as seriously as the surgery itself.
Gum Recession and Nerve Risk
Gum recession around an implant can expose the metal post and, if left unaddressed, compromise the support the implant needs. Patients with diabetes, a smoking history, or inconsistent oral hygiene face a higher risk of this kind of recession and the inflammation that comes with it.
Nerve injury is a rarer risk, generally tied to an implant being placed too close to a nerve, and it can cause numbness or tingling in the lip, chin, or tongue. Careful imaging and treatment planning before surgery, which is standard practice at Sola Dental Spa, is the best way to avoid this. Learn more about our approach on the dental implants page.
“None of these risks should scare a patient away from implants, they are one of the most predictable and successful procedures in dentistry when the planning is right. What matters is a thorough evaluation of your bone and gum health before we ever place anything, so we are solving problems before surgery instead of after.”

Frequently Asked Questions
How common is dental implant failure?
Dental implants have a high overall success rate. The American Association of Oral and Maxillofacial Surgeons reports an overall success rate of around 95 percent, though individual risk depends on bone health, habits like smoking, and how well post operative instructions are followed.
Can a failed implant be replaced?
In many cases, yes. If an implant fails to integrate or needs to be removed, the site can often be treated, sometimes with a bone graft, and a new implant placed once the area has healed.
Does smoking really affect implant success?
Yes. Smoking reduces blood flow to the gums, which slows healing and can interfere with osseointegration. Patients who smoke are generally advised to quit or significantly cut back before and after surgery to improve their odds of success.
How can I lower my risk of complications?
Choosing an experienced provider, getting a thorough bone and gum evaluation beforehand, following post operative care instructions exactly, and maintaining good oral hygiene afterward are the most effective ways to reduce risk.
What happens if I do not have enough jawbone for an implant?
A bone graft or sinus lift can build up the area so it can support an implant. Your dentist will evaluate your bone density with imaging before recommending this step.
