Brief summary: The goal of this clinical trial is to learn if a new mouthwash can help soothing oral mucosa in adult patients with sensitive gums. The main questions it aims to answer are:

* Does the investigated mouthwash soothe red gum?
* Has the mouthwash antibacterial activities? Researchers will compare with a marketed mouthwash to see if the observed effect is due to the formula or to the general rinsing effect of any mouthwash.

Participants will be asked to use the investigated mouthwash or the comparative mouthwash twice a day for 21 days.

Detailed description: Severity of gingival inflammation is evaluated using the Loë \& Silness scale, which includes 4 scores (0=no inflammation, 3=Significant inflammation, redness, accentuated hypertrophy with spontaneous hemorrhagic tendency and ulceration) by the dentist, on Day 0 and on Day 7.

Presence of dental plaque is evaluated using the Loë \& Silness scale, which includes 4 scores (0=no dental plaque, 3=Abundant plaque along the gingival margin; the spaces between the teeth are filled with plaque) by the dentist, on Day 0 and on Day 7.

Changes in the gingival microbiota is evaluated through the analysis of bacteria on D0 and D7 by swab sampling on the occlusal and buccal surfaces at the gum line.

Tolerance (adverse effects) will also be studied by recording any adverse effect.

Eligibility criteria: Inclusion Criteria:

* Person (man, woman) aged 18 or over,
* Person with a gingival index ≥ 2 (according to Loë \& Silness) on at least 10% of teeth (i.e. 3 teeth) at the inclusion visit

* Person agreeing to come for a dental consultation 7 days (+/- 1 day) after the inclusion visit,
