Brief Summary

The goal of this study is to learn if a tooth gel works to alleviate teeth hypersensitivity in adults. It will also learn about the safety of the product. The main question it aims to answer is:

• Does the tooth gel help to improve signs of teeth hypersensitivity? Researchers will compare before and after product use to see if it works to improve teeth sensitivity. Participants will:
• Use assigned products daily for 14 days
• Visit the clinic on the established days during 14 days for check-ups and evaluation

Conditions

Dentine Sensitivity

Outcome Measures

Primary Outcomes (2)

• Change from Baseline in teeth sensitivity to cold air at 14 days.

  Change evaluated by VAS score scale from 0 to 3, where 0 means the absence of pain while 3 is the highest pain.

  From enrolment to the end of use at 14 days.

• Change from Baseline in teeth sensitivity to periodontal probe at 14 days

  Change evaluated by VAS score scale: from 0 to 10, where 0 means the absence of pain while 10 is the highest pain

  From enrolment to the end of use at 14 days.

• Age Groups: Adult (18-64), Older Adult (65+)

You may qualify if:

• Healthy female and male subjects (no specific repartition)
• Aged between 18 years old
• Subjects with dentine hyperesthesia
• Have a minimum of two hypersensitive teeth anterior to non-consecutive molars, with cervical erosion/abrasion or gingival recession, and with a grade greater than or equal to 1 on the verbal rating scale (VRS) after tactile simulation, and greater than or equal to 1 on the Schiff cold air sensitive scale at the beginning of the study.
• Subjects certifying the truthfulness of the personal data disclosed to the investigator
• Subjects able to understand the language used in the investigation canter and the information given by the investigator
• Subjects able to respect the instructions given by the investigator as well as able to respect the study constraints and specific requirements
• Commitment not to change the daily routine or the lifestyle
• Subjects who have not been recently involved in any other similar study
• Commitment not to use during the study period other products with the same effect of the tested product
• Subjects informed about the test procedures and who have signed a consent form.

You may not qualify if:

• Subjects participating or planning to participate in other clinical trials;
• Subjects deprived of liberty by administrative or judicial decision or under guardianship;
• Subjects who cannot be contacted in an emergency;
• Subjects admitted to a health or social center;
• Subjects planning hospitalization during the study;
• Subjects who participated in a similar study without respecting an adequate washout period (used any desensitizing agents during the last three months);
• Subjects who have used anti sensitivity products in the 4 weeks prior to screening;
• Subjects under pharmacological treatments that the investigator considers incompatible with the requirements of the study;
• Subjects who have had active caries within 12 months or who are at risk of caries development (multiple dental restorations, crowns with compromised margin) per examiners discretion;
• Subjects who have shown allergies or sensitivity to any component of the product;
• Subject breastfeeding, pregnant or not willing to take the necessary precautions to avoid pregnancy during the study (for women of childbearing age).
• Any tooth surface adjacent to those surfaces under investigation, which in the opinion of the investigator have any other condition that provides symptoms confusing with those of cervical dentin hypersensitivity.
