Drug addiction takes a heavy toll on teeth and gums

This study examined the oral health consequences of drug addiction in 100 patients undergoing treatment in Northern Portugal rehabilitation clinics. Researchers found a stark picture of oral health challenges: 64% experienced periodontitis (gum disease), 49% reported tooth sensitivity, and 47% had dental caries (cavities). The study population showed extremely high rates of substance use, including 100% alcohol use, 82% tobacco use, and 88.6% illicit drug use—with cannabis and cocaine being the most frequently used illicit substances. Despite 53.8% reporting daily toothbrushing, the majority demonstrated inadequate oral hygiene practices, suggesting that knowing the importance of brushing isn't enough without proper technique or access to professional care.

The research revealed important connections between drug use duration and oral disease progression. Periodontitis and gingival bleeding were significantly associated with how long individuals had used illicit drugs, indicating that prolonged substance abuse compounds oral health deterioration. Additionally, toothbrushing frequency directly correlated with reduced gingival bleeding and inflammation, while the use of dental hygiene aids showed a protective association against periodontitis. These findings highlight that even modest improvements in oral hygiene practices could meaningfully reduce disease severity in this vulnerable population.

The study underscores a critical gap in addiction treatment: oral health is rarely integrated into comprehensive rehabilitation programs, despite being severely compromised in nearly all patients. For cannabis users specifically, these findings suggest that the combination of multiple substance use (cannabis with alcohol and tobacco) creates compounded oral health risks. The researchers advocate for incorporating dental screening, professional cleaning, and oral hygiene education as standard components of addiction treatment to address this neglected but significant aspect of recovery and overall health.
