Study Arms:
- AMY-101 treatment (Type: ACTIVE_COMPARATOR): Subjects who meet inclusion criteria will be enrolled in the study and sites will be randomized to treatment groups (AMY-101 or placebo) in split mouth design. In the AMY-101 treatment arm after clinical assessments and sample collection at baseline, test treatments will be administered to each of the interproximal papilla and will be repeated on Day 7 and 14.
- Placebo (Type: PLACEBO_COMPARATOR): Subjects who meet inclusion criteria will be enrolled in the study and sites will be randomized to treatment groups (AMY-101 or placebo) in split mouth design. In the placebo arm, after clinical assessments and sample collection at baseline, placebo treatments will be administered to each of the interproximal papilla and will be repeated on Day 7 and 14.

Based on this trial design, predict the completion outcome and termination type (if applicable).
