The DHEQ is a condition-specific measure of oral-health related quality-of-life (OHrQoL) in relation to dentin hypersensitivity (DH). Section 2 of DHEQ included 34 questions grouped into 5 separate domains: Restrictions(Q1-4), Adaptation(Q5-16), Social Impact(Q17-21), Emotional Impact(Q22-29), and Identity(Q30-34). Participants scored each question using a 7-point scale ranging from 1 to 7 where 1=strongly disagree, 2=disagree, 3=disagree a little, 4=neither agree nor disagree, 5=agree a little, 6=agree, and 7=strongly agree. The total score was derived from the sum of scores across all domains (Q1-34) and ranged from 34 to 238, where lower score indicated better quality of life in relation to DH. Change from Baseline was calculated by subtracting the Baseline score from the score at each indicated timepoint. A negative change from Baseline indicated improvement in OHrQoL.

mITT population included all participants who completed at least one use of study product and had at least 1 post-baseline derived DHEQ total score. The Mixed Model with Repeated Measures (MMRM) included all participants in the mITT population in each analysis. Number analyzed represents the number of participants with non-missing data in the MMRM at the indicated timepoint.

Restrictions domain of DHEQ evaluated 'the ways in which any sensations in teeth affected participants in their daily life'. It included 4 questions each scored using a 7-point scale ranging from 1 to 7 where 1=strongly disagree, 2=disagree, 3=disagree a little, 4=neither agree nor disagree, 5=agree a little, 6=agree, and 7=strongly agree. Thus, the total score ranged from 4 to 28. Lower score indicated less effect of sensations on participant's daily life. Change from Baseline was calculated by subtracting the Baseline score from the score at each indicated timepoint. A negative change from Baseline indicated improvement (less effect of sensations on participant's daily life).

mITT population. The MMRM included all participants in the mITT population in each analysis. Number analyzed represents the number of participants with non-missing data in the MMRM at the indicated timepoint.

Adaptation domain of DHEQ evaluated 'the ways in which the sensations in teeth had forced participants to change things in their daily life'; 'things they did in their daily life to avoid experiencing the sensations in their teeth'. It included 12 questions each scored using a 7-point scale ranging from 1 to 7 where 1=strongly disagree, 2=disagree, 3=disagree a little, 4=neither agree nor disagree, 5=agree a little, 6=agree, and 7=strongly agree. Thus, the total score ranged from 12 to 84, where lower score indicated less effect of sensations on participant's daily life. Change from Baseline was calculated by subtracting the Baseline score from score at each indicated timepoint. A negative change from Baseline indicated improvement (less effect of sensations on participant's daily life).

mITT population. The MMRM included all participants in the mITT population in each analysis. Number analyzed represents the number of participants with non-missing data in the MMRM at the indicated timepoint.

Social Impact domain of DHEQ evaluates 'the way the sensations affect participants when they are with other people or in certain situations.' It included 5 questions each scored using a 7-point scale ranging from 1 to 7 where 1=strongly disagree, 2=disagree, 3=disagree a little, 4=neither agree nor disagree, 5=agree a little, 6=agree, and 7=strongly agree. Thus, the total score ranged from 5 to 35, where lower score indicated less effect of sensations on participant's social life. Change from Baseline was calculated by subtracting the Baseline score from score at each indicated timepoint. A negative change from Baseline indicated improvement (less effect of sensations on participant's social life).

mITT population. The MMRM included all participants in the mITT population in each analysis. Number analyzed represents the number of participants with non-missing data in the MMRM at the indicated timepoint.

Emotional Impact Domain of DHEQ evaluated 'the way the sensations in participant's teeth make them feel.' It included 8 questions each scored using a 7-point scale ranging from 1 to 7 where 1=strongly disagree, 2=disagree, 3=disagree a little, 4=neither agree nor disagree, 5=agree a little, 6=agree, and 7=strongly agree. Thus, the total score ranged from 8 to 56, where lower score indicated less impact of sensations on participant's emotions. Change from Baseline was calculated by subtracting the Baseline score from score at each indicated timepoint. A negative change from Baseline indicated improvement in OHrQoL (less impact of sensations on participant's emotions).

mITT population. The MMRM included all participants in the mITT population in each analysis. Number analyzed represents the number of participants with non-missing data in the MMRM at the indicated timepoint.

Identity Domain of DHEQ evaluated 'what the sensations in participant's teeth mean for them.' It included 5 questions each scored using a 7-point scale ranging from 1 to 7 where 1=strongly disagree, 2=disagree, 3=disagree a little, 4=neither agree nor disagree, 5=agree a little, 6=agree, and 7=strongly agree. Thus, the total score ranged from 5 to 35, where lower score indicated less impact of sensations on participant's identity. Change from Baseline was calculated by subtracting the Baseline score from score at each indicated timepoint. A negative change from Baseline indicated improvement (less impact of sensations on participant's identity).

mITT population. The MMRM included all participants in the mITT population in each analysis. Number analyzed represents the number of participants with non-missing data in the MMRM at the indicated timepoint.

DHEQ Section 1 included 3 questions about participant's sensitive teeth and its impact on everyday life. Participants scored Q1 (how intense are the sensations?) on a scale of 1 (not at all intense) to 10 (worst imaginable); Q2 (how bothered are you by any sensations?) on a scale of 1 (not at all bothered) to 10 (extremely bothered); Q3 (how well can you tolerate sensations?) on a scale of 1 (can easily tolerate) to 10 (can't tolerate at all). The total score for each question ranged from 1 to 10; where lower scores indicated less intense, less bothersome and tolerable sensations. Change from Baseline was calculated by subtracting the Baseline score from score at each indicated timepoint. A negative change from Baseline indicated improvement in intensity, botheration and tolerability of sensations.

mITT population. The MMRM included all participants in the mITT population in each analysis. Number analyzed represents the number of participants with non-missing data in the MMRM at the indicated timepoint.

Global Oral Health was evaluated using a single question of DHEQ. Participants rated the overall health of their mouth, teeth, and gums using a 6-point scale ranging from 1 to 6 where 1=excellent, 2=very good, 3=good, 4=fair, 5=poor, and 6=very poor. Lower score indicated better oral health. Change from Baseline was calculated by subtracting the Baseline score from score at each indicated timepoint. A negative change from Baseline indicated improvement in global oral health.

mITT population. The MMRM included all participants in the mITT population in each analysis. Number analyzed represents the number of participants with non-missing data in the MMRM at the indicated timepoint.

Effect on life was evaluated using 4 questions of DHEQ (Section 2, Q36-39) about how much the sensations in teeth affected participant's life overall. Participants scored each question on a 5-point scale ranging from 0 to 4 where 0=not at all, 1=a little, 2=somewhat; 3=quite a bit, and 4=very much. Thus, the total score ranged from 0 to 16, where lower score indicated less effect of sensations on participant's life overall. Change from Baseline was calculated by subtracting the Baseline score from score at each indicated timepoint. A negative change from Baseline indicated improvement in overall quality of life (less effect of sensations on participant's life overall).

mITT population. The MMRM included all participants in the mITT population in each analysis. Number analyzed represents the number of participants with non-missing data in the MMRM at the indicated timepoint.

The DHEQ is a condition-specific measure of OHrQoL in relation to DH. Section 2 of DHEQ included 34 questions grouped into 5 separate domains: Restrictions(Q1-4), Adaptation(Q5-16), Social Impact(Q17-21), Emotional Impact(Q22-29), and Identity(Q30-34). Participants scored each question using a 7-point scale ranging from 1(strongly disagree) to 7(strongly agree) where lower score indicated better quality of life in relation to DH. Scores 5 to 7 indicated agreement with the statement mentioned in the question, where 5=Agree a little, 6=Agree and 7=Strongly agree. Percentage of participants with scores 5 to 7 for each statement in the 5 DHEQ domains were reported.

mITT population. Only those participants available at the indicated timepoints were analyzed.

NPRS was an 11-point segmented numeric version of a Visual Analogue Scale from which the participant selected a score from 0 to 10 that best reflected the intensity of their pain, where 0=no pain and 10=worst possible pain. Higher scores indicated of greater pain intensity. Change from Baseline was calculated by subtracting the Baseline score from score at each indicated timepoint. A negative change from Baseline indicated improvement (reduction in pain intensity).

mITT population. The MMRM included all participants in the mITT population in each analysis. Number analyzed represents the number of participants with non-missing data in the MMRM at the indicated timepoint.

Participants were asked to rate their satisfaction with the DH treatment using NRS. NRS is an 11-point ordinal scale used to assess satisfaction with the overall management of the condition for which the participant sought help from treatment. The score ranged from 0 (completely dissatisfied) to 10 (completely satisfied), where higher scores indicated greater satisfaction with DH treatment.

mITT population. Here, overall number analyzed is defined as the number of participants with data available for analysis of this outcome measure.

Participants described their oral hygiene habits by completion of an OHQ. It included 9 questions: Q1:How frequently do you normally brush your teeth? Q2:Have you had a professional or self-applied tooth whitening treatment in the last 2 weeks? Q3:Have you had a professional tooth cleaning in the last 2 weeks? Q4:Have you ever been diagnosed with sensitive teeth by a dentist? Q5: When was the last time you visited a dentist/hygienist? Q6:Do you use a toothpaste designed specifically for sensitive teeth?
