- Intervention Model: CROSSOVER
- Observational Model: None
- Primary Purpose: None
- Time Perspective: None
- Masking: DOUBLE
- Phase: None
- Number of Arms: 5.0

Eligibility Criteria:
Inclusion Criteria:~* sign an informed consent, authorization for the release of health information for research and provide medical history information, including medications, prior to their participation;~* be between 18 and 80 years old and in general good health;~* willingness to use a reliable form of contraception or abstaining during the course of the study (females of child-bearing potential only)~* wear a removable mandibular partial denture with sufficient room in one posterior buccal flange area to accommodate two enamel specimens (required dimensions 12×7 mm);~* be willing and capable of wearing their removable mandibular partial dentures 24 hours a day for a total of five, three-week test periods;~* be in good dental health with no active caries or periodontal disease;~* agree to comply with all subjects' responsibilities as stated in the protocol (e.g. use of study products, attendance at appointments, etc.);~* have a salivary flow rate in the range of normal values (unstimulated whole saliva flow rate ≥ 0.2 ml/min; gum base stimulated whole saliva flow rate ≥ 0.8 ml/min).~* Be able to tolerate the taste and room temperature of the mixed milk product as demonstrated by drinking the milk at screening~Exclusion Criteria:~be pregnant, intending to become pregnant during the study period or breast feeding. A urine pregnancy test will be required at screening, the start of each treatment visit and the last study visit for all subjects of child-bearing potential to confirm the subject is not pregnant.~* have any medical condition that could be expected to interfere with the subject's safety during the study period;~* demonstrate an inability to comply with study procedures;~* have factors which could contraindicate their participation, such as any condition requiring the need for antibiotic premedication prior to a dental treatment, a condition requiring the need for long-term antibiotic use, blood thinning medications that prohibit the safe conduct of a dental cleaning\* or previous use of the weight loss medications Fen Phen® or Redux®. (\*Note: Subjects who are taking blood thinners in which written verification is obtained from their physician indicating their PT/INR levels (anti-coagulation blood levels) are at an acceptable level to avoid serious complications, such as bleeding during dental cleanings, may be accepted into the study at the discretion of the Investigator.)~* be currently taking or have ever taken a bisphosphonate drug (i.e. Fosamax®, Actonel®, Boniva®, Reclast®, or Zometa®) for treatment of osteoporosis.~* be lactose intolerant or have known allergy or intolerance to milk or milk products
