Adequate contraception is defined as abstinence, oral contraceptive, either combined or progestogen alone or injectable progestogen or implants of levonorgestrel or estrogenic vaginal ring or percutaneous contraceptive patches or intrauterine device or intrauterine system or double barrier method (condom or occlusive cap \[diaphragm or cervical vault caps\] plus spermicidal agent \[foam, gel, film, cream, suppository\]) or male partner sterilization prior to the female participant's entry into the study, and this male is the sole partner for that participant).~* Participant will be current and regular (twice daily), users of an over the counter (OTC) Monograph or cosmetic oral rinse.~* Participant will be cell phone owners so that they can contactable by SMS.~Exclusion Criteria:~* A woman who is known to be pregnant or who is intending to become pregnant over the duration of the study.~* A woman who is breast-feeding.~* Known or suspected intolerance or hypersensitivity to the study materials (or closely related compounds) or any of their stated ingredients.~* Participation in another clinical study (including cosmetic studies) or receipt of an investigational drug within 30 days of the screening visit or previous participation in this study.~* Recent history (within the last year) of alcohol or other substance abuse.~* An employee of the sponsor or the study site or members of their immediate family.~* Presence of chronic debilitating disease which, in the opinion of the investigator, could affect study outcomes.~* Any condition which, in the opinion of the investigator, causes xerostomia.~* Dental prophylaxis within 4 weeks of Screening.~* Tongue or lip piercing.~* Desensitizing treatment within 8 weeks of Screening (professional sensitivity, treatments and non-dentifrice sensitivity treatments).~* Gross periodontal disease, treatment of periodontal disease (including surgery) within 12 months of Screening, scaling or root planning within 3 months of Screening.~* Teeth bleaching and any teeth whitening procedures within 8 weeks of Screening.~* Tooth with evidence of current or recent caries, or reported treatment of decay within 12 months of Screening.~* Tooth with exposed dentine but with deep, defective or facial restorations, teeth used as abutments for fixed or removable partial dentures, dental implants, teeth with full crowns or veneers, orthodontic bands or cracked enamel. Sensitive teeth with contributing aetiologies other than erosion, abrasion or recession of exposed dentine.~* Sensitive tooth not expected to respond to treatment with an over-the-counter dentifrice in the opinion of the investigator.~* Use of an oral care product indicated for the relief of dentine hypersensitivity within 8 weeks of screening (Participants will be required to bring their current oral care products to the site in order to verify the absence of known anti-sensitivity ingredients).~* Daily doses of medication/treatments which, in the opinion of the investigator, could interfere with the perception of pain. Examples of such medications include analgesics, anticonvulsants, antihistamines that cause marked or moderate sedation, sedatives, tranquilisers, anti-depressants, mood-altering and anti-inflammatory drugs.~* Currently taking antibiotics or has taken antibiotics within two weeks of Baseline.~* Daily dose of a medication which, in the opinion of the investigator, is causing xerostomia.~* Presence of kidney disease, hyperoxaluria, or any other condition that may be exacerbated by oxalic acid or oxalate salts.~* Presence of chronic debilitating disease which, in the opinion of the investigator, could affect study outcomes.~* Any participant who, in the judgment of the investigator, should not participate in the study.
