Oral Health Research Topics

Goal

Prevent and control oral and craniofacial diseases, conditions, and injuries, and improve access to preventive services and dental care.

Overview

The health of the teeth, the mouth, and the surrounding craniofacial (skull and face) structures is central to a person’s overall health and well-being. Oral and craniofacial diseases and conditions include:

  • Dental caries (tooth decay)
  • Periodontal (gum) diseases
  • Cleft lip and palate
  • Oral and facial pain
  • Oral and pharyngeal (mouth and throat) cancers
  • Xerostomia (dry mouth)

The significant improvement in the oral health of Americans over the past 50 years is a public health success story. Most of the gains are a result of effective prevention and treatment efforts. One major success is community water fluoridation, which now benefits about 7 out of 10 Americans who get water through public water systems.

However, some Americans do not have access to preventive programs. People who have the least access to preventive services and dental treatment have greater rates of oral diseases. A person’s ability to access oral health care is associated with factors such as education level, income, race, and ethnicity.

Objectives in this topic area address a number of areas for public health improvement, including the need to:

  • Increase awareness of the importance of oral health to overall health and well-being
  • Increase acceptance and adoption of effective preventive interventions
  • Reduce disparities in access to effective preventive and dental treatment services

Why Is Oral Health Important?

Oral health is essential to overall health. Good oral health improves a person’s ability to speak, smile, smell, taste, touch, chew, swallow, and make facial expressions to show feelings and emotions.

However, oral diseases, from cavities to oral cancer, cause significant pain and disability for many Americans.

Understanding Oral Health

Good self-care, such as brushing with fluoride toothpaste, daily flossing, and professional treatment, is key to good oral health. Health behaviors that can lead to poor oral health include:

  • Tobacco use
  • Excessive alcohol use
  • Poor diet

Barriers that can limit a person’s use of preventive interventions and treatments include:

  • Limited access to and availability of dental services
  • Lack of awareness of the need for care
  • Cost
  • Fear of dental procedures

There are also social determinants that affect oral health. In general, people with lower levels of education and income, and people from specific racial/ethnic groups, have higher rates of disease. People with disabilities and other health conditions, like diabetes, are more likely to have poor oral health.

  • School-based dental sealant programs, which focus on sealing the chewing surfaces of permanent molar teeth, usually target schools that serve children from low-income families. Dental sealants can prevent up to 80% of tooth decay in the treated teeth.

Emerging Issues in Oral Health

Major improvements have occurred in the Nation’s oral health, but some challenges remain. A recent Centers for Disease Control and Prevention (CDC) publication reported that despite dental sealants preventing over 80% of dental cavities, only 1 in 3 children aged 6 to 8 has a dental sealant. ,

Lack of access to dental care for all ages remains a public health challenge. This issue was highlighted in a 2008 Government Accountability Office (GAO) report that described difficulties in accessing dental care for low-income children. In 2013, GAO reported an increase in dental services among children who were Medicaid and CHIP beneficiaries, but children still visited the dentist less often than privately insured children.

Potential strategies to improve access to dental services and improve oral health of children and adults include:

  • Implementing and evaluating activities that have an impact on health behavior
  • Promoting interventions to reduce tooth decay, such as dental sealants and fluoride use
  • Evaluating and improving methods of monitoring oral diseases and conditions
  • Increasing the capacity of State dental health programs to provide preventive oral health services
  • Increasing the number of community health centers with an oral health component
