it’s not unusual to have discomfort after an impression for a dental implant if the restoring dentist placed a larger healing abutment in the implant to widen the platform. The chance of having impression material under the gums around the implant is highly unlikely. Speak to your dentist if the issue continues to give you discomfort
The short answer to your question is Yes. Depending how the implant was restored will determine the ease of the replacement. If the crown was screw retained then the dentist can easily access the screw and remove the old crown for repair or replacement. If the Implant crown was cemented then it’s more difficult to conservatively replace. Often the crown needs to be cut off to expose the Implant abutment. Cost could be anywhere from $1000-2000. This is a moderate to advanced procedure depending upon the circumstances. Look for a dentist who is comfortable with this type of dentistry.
The cost of Invisalign varies by the number of retainers needed to achieve the desired result. Many of the answers I have read by some dental professionals unfortunately are incorrect. Simple tooth movement may be effective for only a single arch and often both arches do not need to be treated together. The process to design your smile starts with either a scan or impressions of your teeth. The Dentist will then prescribe a treatment based on the number of trays for teeth movement. Let's say Express 5. The software will show the maximum shift and best result with this number of retainers. Often we will need to move to a different system with more trays. Example Express 10. If we can achieve the result great, if not, the treatment may need to move to a full case. Always start conservative, assess then reevaluate to see if more aligners and time is required. Fail to Plan, Plan to fail.
if you have any concerns regarding the healing of a dental surgical procedure I would recommend calling your dentist to have the area looked at. Stitches serve their purpose after 3-4 days and often become looser as the tissue heals and the swollen area shrinks. This is normal. Did the implant surgeon place a bone graft? Did they place a resorbable membrane? Although the goal is to get primary closure of the surgical site, often the membrane can get exposed during healing. Sometimes particles of the bone graft can escape. Keeping the membrane clean with daily use of a gentle hydrogen peroxide is often recommended until the area closes over. Caution is always best so call your dentist to have them evaluate.
A periodontist is a specialist of the gums and its surrounding bone structure whose opinion weighs great value. It's important that you recieve multiple treatment options with the risks and benefits of each procedure. With that information you can make an informed decision as to the best treatment for you. Recession alone would not cause the symptoms and bone loss you suggest. Did the tooth ever have exposure to trauma? It is possible the filling to cover the root may have caused pupal damage leading to apical periodontitis and bone loss. A root canal would be the treatment of choice to save the tooth. The gum recession could be treated by removing the filling and performing a connective tissue graft to restore the lost gum tissue. Maintaining a tooth is often the best route. Single Implant placement in the anterior esthetic zone is often a difficult and challenging procedure to achieve great results.
