Asthma and tooth decay have been suspected of being linked through frequent mouth breathing and the use of inhaled asthma medications. However, existing research has been inconsistent regarding whether asthma or asthma medications increase the risk of cavities in permanent teeth.
Teenagers: Is there a connection between asthma, asthma medication, and cavities?
A study conducted in Switzerland aimed to investigate whether asthma, the age of onset, or the use of asthma medications are associated with tooth decay in 13-year-old adolescents. The research was part of the “Generation R Study,” a population-based prospective cohort study. Data on asthma, medication use, and potential influencing factors were collected through parental questionnaires. Tooth decay in permanent teeth was assessed using the DMFT index (“Decayed, Missing, and Filled Teeth”).
Population-based cohort study with 3,356 adolescents
The study population included 3,356 participants (average age: 13.6 ± 0.34 years; 48.8% male). The prevalence of cavities was 35.2%. 15.3% of the adolescents had ever been diagnosed with asthma. The findings showed no significant associations between (current) asthma, age of asthma onset, or the use of asthma medications at age 13 and the risk of tooth decay, with odds ratios ranging from OR: 0.64 (95% confidence interval, CI: 0.41 – 1.02) to OR: 1.27 (95% CI: 0.79 – 2.05).
No evidence of increased cavity risk with asthma
This large study of adolescents found no link between asthma, asthma medications, and cavities. The results align with several other large, population-based cohort studies, researchers report.
