In this study a tooth that needs to be extracted will be replaced by an implant (artificial root) placed at the same appointment as the extraction. The investigators want to observe how the gums change shape with healing in two different scenarios: 1. If the soft tissue around your tooth is thin, following extraction and implant placement an extra soft tissue graft (taken from your palate) in the area in order to increase the thickness of your gums after healing. 2. If the soft tissue around your tooth is thick, the implant will be placed without a soft tissue graft. Previous studies have shown that both methods work and can give good results. In fact the two methods are used routinely but they have never been compared objectively to one another in the same research study. The main purpose of this study is to evaluate if there is any difference in terms of esthetic outcomes between these two treatment modalities after a crown has been placed on the implant.

Mid Facial Mucosal Level at Implant Site
Baseline will be at the time of crown delivery. Thereafter, the mid facial mucosal level at implant site will be recorded at 3, 6, 12 months after crown delivery.
Time frame: Change from Baseline to 3 months
PES/WES (Pink Esthetic Score, White Esthetic Score).
Baseline will be at the time of crown delivery. Secondary outcome measures will be recorded at 12 months after crown delivery. The PES (Pink Esthetic Score) and WES (White Esthetic Score) scales are 10 point scales, made up of 5 categories, each with a 2 point value. Each category is scored out of 2, and the scores totaled to give an optimal score out of 10, and then the two scores (PES and WES) added to give a total score out of 20, with 20 being the highest possible score (best outcome) and 0 being the worst outcome.
Time frame: Approximately 1 year after baseline
Probing Depth
Baseline will be at the time of crown delivery. Secondary outcome measures will be recorded at baseline, 3 and 12 months after crown delivery. The measurement of the pocket around the implanted tooth, measured with a graduated probe. A healthy pocket depth is around 3 mm with no bleeding during the measurement process. The values are totaled and a mean score of all the readings is reported.
Time frame: Up to 1 year after baseline
Modified Plaque Index
Baseline will be at the time of crown delivery. Secondary outcome measures will be recorded at 3, 6, 12 months after crown delivery. Measurement of amount of plaque build-up on teeth, using a scale of 0 (no plaque detection), to 3 (an abundance of soft matter). The scores are totaled and a mean score reported.
Time frame: Up to 1 year after baseline
Modified Bleeding Index
Baseline will be at the time of crown delivery. Secondary outcome measures will be recorded at 3, 6, 12 months after crown delivery. Bleeding from the gums is measured on probing the gum and measured on scale of 0 to 5, with 0 being the best outcome, with no bleeding, and 5 being the worst outcome, with spontaneous bleeding. The scores are totaled and a mean score reported.
Time frame: Up to 1 year after baseline
Radiographic Bone Level
Baseline will be at the time of crown delivery. Secondary outcome measures will be recorded at baseline 3, and 12 months after crown delivery. Radiographic bone measurements recorded following final restoration placement (baseline), after 3 and 12 months of loading, and change between these time points. A positive value indicates bone loss and a negative value indicates bone gain. BIC (Bone implant contact)= Distance from implant shoulder to first bone to implant contact.
Time frame: Up to 1 year after baseline
