What Does It Mean When a Dental Implant Screw Is Exposed?
A dental implant screw exposed above the gumline means that a metal component of your implant system is visible or can be felt with your tongue. This is one of the more common concerns patients have during the months between implant placement and receiving their final crown or prosthesis.
Dental implants have several parts. The implant body is a threaded post that sits inside the jawbone. A small cover screw is placed on top of the implant to protect the internal connection while the bone heals around the post. In a two-stage procedure, the cover screw is buried beneath the gum tissue. In a one-stage procedure, a healing abutment extends through the gum intentionally. Understanding which type of procedure you had helps determine whether the exposed screw is expected or not.
One-Stage vs. Two-Stage Implant Placement
In a one-stage procedure, the surgeon places a healing abutment that intentionally sits above the gumline from day one. Seeing metal above the gum after this type of surgery is completely normal.
In a two-stage procedure, the cover screw is buried under the gum tissue and the site is sutured closed. The gum is reopened months later to attach the healing abutment. If you had a two-stage procedure and can see the cover screw before your second surgery, the tissue has opened or receded in a way that was not planned.
Why a Dental Implant Cover Screw Becomes Exposed
Several factors can cause a buried cover screw to become visible. Some are minor and resolve on their own. Others need clinical attention to prevent complications.
Gum Recession and Thin Tissue
Thin gum tissue over the implant site is one of the most frequent causes of screw exposure. Some patients naturally have thinner soft tissue, especially along the front of the upper jaw. As the tissue heals and settles after surgery, it may shrink enough to reveal the underlying cover screw. Patients with a history of gum recession are at higher risk.
Healing Complications
If the surgical site does not heal as expected, tissue can break down over the cover screw. Premature suture loss, infection at the incision line, or trauma to the area (such as chewing hard food on the site too early) can all disrupt the tissue seal. Smoking significantly increases the risk of poor soft tissue healing around dental implants.
Bone Loss or Implant Position
If the implant was placed slightly too shallow or too far toward the cheek side of the ridge, the bone and tissue covering it may be thinner than ideal. Over time, even minor bone remodeling can leave the cover screw exposed. In rarer cases, early bone loss around the implant neck (peri-implant bone resorption) causes the tissue to pull away and expose the hardware.
Is an Exposed Implant Screw Normal or a Problem?
Whether an exposed dental implant screw is a concern depends on the type of procedure, the timing, and the symptoms you are experiencing. Not every case of screw exposure means something has gone wrong.
If you had a one-stage procedure and the healing abutment is visible, this is expected. Your surgeon designed it that way. The tissue should form a healthy cuff around the abutment as it heals.
If you had a two-stage (submerged) procedure and the cover screw is showing before your planned second surgery, this is not part of the normal timeline. However, it does not automatically mean the implant is failing. Many cover screw exposures are minor and do not affect the long-term outcome of the implant, as long as the area stays clean and free of infection.
Signs That the Exposure Is a Problem
- Redness, swelling, or tenderness around the exposed screw that worsens over time
- Pus or discharge from the gum tissue near the implant
- A persistent bad taste or odor coming from the implant site
- The screw feels loose or the implant itself feels mobile when you press on it
- Pain when biting or pressing on the area, especially if it develops weeks after surgery
Treatment Options for an Exposed Implant Screw
Treatment depends on why the screw is exposed, whether infection is present, and how far along you are in the healing process. Your prosthodontist or periodontist will evaluate the site and recommend one of several approaches.
Monitoring and Oral Hygiene
If the exposure is minor, the tissue is healthy, and the implant is stable, your specialist may choose to monitor the area. You will be instructed to keep the site clean with a soft toothbrush and an antimicrobial rinse. In some cases, the tissue adapts around the exposed screw on its own without further intervention.
Soft Tissue Grafting
When thin tissue or gum recession caused the exposure, a soft tissue graft can rebuild the tissue over and around the implant. A periodontist typically performs this procedure using tissue from the roof of your mouth or a donor tissue product. The graft creates a thicker, more stable tissue seal that protects the implant long-term.
Replacing the Healing Component
In some cases, the specialist may replace the cover screw with a taller healing abutment. This approach works when the tissue level has settled lower than expected but is otherwise healthy. The healing abutment is designed to guide tissue growth and create a properly shaped opening for the final crown.
Treating Infection Around the Implant
If the exposed screw has allowed bacteria to collect and cause infection, the specialist will clean the area thoroughly. This may include irrigating the site, prescribing antibiotics, and in some cases removing inflamed tissue. Controlling infection early is critical. Left untreated, it can progress to peri-implantitis and threaten the bone supporting the implant.
Cost of Treating an Exposed Implant Screw
The cost of addressing a dental implant screw exposed through the gum varies depending on the treatment needed. A simple monitoring approach with follow-up visits may cost little beyond your regular appointment fees. Soft tissue grafting around an implant typically ranges from $600 to $1,800 per site. Costs vary by location, provider, and case complexity.
If the exposure occurred during the original healing period, some providers include follow-up treatment as part of the initial implant fee. Ask your specialist whether corrective care is covered under your original treatment agreement. Dental insurance may cover a portion of soft tissue grafting if it is deemed medically necessary, though coverage for implant-related procedures varies widely by plan.
When to Call Your Specialist
Contact your prosthodontist, periodontist, or oral surgeon if you notice any metal showing through the gum that was not there before. While not every exposed screw is an emergency, early evaluation prevents small issues from becoming larger problems.
Seek prompt attention if you have pain that is worsening, visible swelling or pus, a loose-feeling implant, or a bad taste or odor from the site. These may indicate infection or implant instability that requires timely treatment.
Even if the exposure seems minor and painless, mention it at your next scheduled visit. Your specialist can check the stability of the implant, assess the tissue health, and decide whether treatment is needed before moving forward with your final restoration.
