Brief Summary:
In this randomized controlled study, the investigators compare two classes of behavioral approaches to change habits and health outcomes with an application to dental health: cognitive vs. behavioral financial incentives. Under cognitive incentives subjects are paid to correctly answer health-related quizzes. Under behavioral incentives subjects earn money for making healthy choices. The investigators apply these incentives to toothbrushing, a daily health-related behavior critical to the prevention of dental caries and periodontal disease, two high-burden conditions among US adults.

36 Participants will be sent a new toothbrush and will be asked to use it in place of their current brush. They also receive twice daily reminders via sms to brush their teeth.
Experimental: Financial Incentives
36 Participants will receive a toothbrush and twice daily reminders to brush their teeth. They will also be offered financial incentives twice a day to brush their teeth.
Behavioral: Financial Incentives
Experimental: Cognitive Incentives
36 Participants will receive a toothbrush and twice daily reminders to brush their teeth. Twice a week, they will receive text messages (SMS) with a short quiz question related to oral hygiene behavior and oral health. Participants will receive a reward if they answer correctly via text message.
