Adults subjects provide written informed consent and adolescent subjects give written or verbal assent, as appropriate, and parent(s) or legal guardian(s) give written informed consent
Female subjects of childbearing potential must agree to use one of the following forms of contraception from screening through the last study visit: hormonal (oral, implant, or injection) begun >30 days prior to screening; barrier (condom, diaphragm, or cervical cap with spermicide); intrauterine device (IUD). Acceptable contraceptive options may also include abstinence, relationship with a same sex partner or partner who has had a vasectomy at least six (6) months prior to the screening visit
Negative urine pregnancy test in all females of childbearing potential (past menarche)
Male subjects of sexual activity age: willing to use contraception or abstain from sexual activity beginning with the first exposure to study drug and continuing until discharged from the study due to completion or Early Termination

Healthy, as determined by the Investigator (in consultation with the Medical Monitor, as needed), based on medical and dental history, concurrent illnesses, laboratory results, concomitant medications, oral cavity assessment, and targeted physical examination (general, extraoral, head and neck) during Screening.

Note: Subjects on a stable dose of medication may be eligible for screening and will be assessed by the medical monitor on a case-by-case basis.

Have a minimum of 12 bicuspids and molars with a minimum of 8 molars and bicuspids NOT having restorations, crowns or sealants
Demonstrated ability to expectorate ≥2 mL of stimulated saliva in 5 minutes
Have a salivary S. mutans of 1.0 x 10^5 CFUs/mL or greater at Screening using mitis salivarius-bacitracin (MSB) agar plating
Willing to refrain from using non-study dentifrice and other non-study oral care products (oral care rinses, fluoride products, etc.) during the study
Willing to postpone elective dental procedures (e.g., dental cleanings) between Screening and final post-treatment visit (End of Study or Early Termination)
Willing and able to comply with oral hygiene and diet instructions
Able to communicate with the Investigator/study center personnel, understand and comply with the study requirements, and willing to return for protocol-specified visits at the appointed times

Exclusion Criteria:

Advanced periodontal disease

Active caries lesion(s) within 30 days prior to study drug administration (confirmed by comprehensive caries examination including standard radiographs). Subjects presenting with insipient, non-cavitated lesion(s) are not excluded.

Note: If radiographs are deemed appropriate for the study and taken within 6 months prior to the Screening visit, these may be used for determining eligibility and are not required to be repeated at Screening

Partially erupted teeth where the entire crown is not erupted or an operculum is present
Medical condition (e.g., artificial heart valve, history of infective endocarditis, cardiac transplant with valvular dysfunction, congenital heart disease or total joint replacement) for which antibiotics are recommended prior to dental visits and/or procedures
Pathologic lesions of the oral cavity (suspicious or confirmed)
Full dentures or permanent orthodontic appliances, e.g., braces, buccal or lingual brackets. Note: Partial dentures, removable retainers and night guards are not excluded, provided that they are cleaned regularly throughout the duration of the study

Medical history indicating the woman is pregnant, breastfeeding/lactating or has a positive urine pregnancy test
Participation in a clinical trial or receipt of a non-FDA approved therapy within 30 days prior to study drug administration (depending on the specifics, participation in an observational study is not necessarily excluded)
Participation in a previous C16G2 clinical trial having received either C16G2 Strip, C16G2 Varnish or Placebo Varnish
Presence of any condition or concurrent illness, which in the opinion of the Investigator, would compromise normal immune function (e.g., diabetes, rheumatoid arthritis, lupus, liver disease, organ transplant, etc.), interfere with the use of study dentifrice and oral care products, or interfere with the ability to comply with study requirements, or jeopardize the safety of the subject or the validity of the study results
