Vaping, or the use of electronic cigarettes, is common among young adults, many of whom are undergoing orthodontic treatment. Vaping involves inhaling an aerosol created by heating a liquid, which usually contains nicotine, flavorings, propylene glycol, and vegetable glycerin.
While often seen as less harmful than smoking, the chemical components and physical act of vaping introduce specific complications for patients wearing braces. Braces create a complex oral environment where the negative effects of vaping are significantly amplified, threatening the hardware, biological tissues, and overall treatment schedule.
Compromising the Orthodontic Hardware
Vape aerosols contain humectants like propylene glycol and vegetable glycerin, which create a sticky film when they settle. This residue clings to the intricate surfaces of the brackets, wires, and elastics, forming a trap for plaque and bacteria that is difficult to remove. The constant presence of this sticky layer promotes localized bacterial growth, compromising the cleanliness required for orthodontic success.
The adhesive material used to bond brackets can also be chemically and physically affected by the aerosol. Heat and chemical exposure may weaken the bond strength of the dental cement over time. A weakened bond increases the risk of a bracket detaching, requiring unplanned visits for re-bonding.
The aerosol can also cause discoloration of orthodontic appliances, especially clear ceramic brackets or tooth-colored wires, due to chemicals and nicotine. Vaping accelerates the force degradation of elastomeric chains—the small rubber bands used to move teeth. When these chains lose their pulling power faster than expected, the loss of mechanical force directly interferes with planned tooth movement.
Accelerated Dental and Gum Damage
A significant consequence of vaping with braces is the acceleration of dental decay, primarily through the formation of white spot lesions (WSLs). Braces already make oral hygiene challenging, creating areas around the brackets where plaque acids can accumulate and begin to demineralize the enamel. Vaping exacerbates this process by causing xerostomia, or dry mouth, where salivary glands produce insufficient saliva.
Saliva naturally buffers acids and helps remineralize enamel, but reduced flow removes this natural defense mechanism. The environment under and immediately around the brackets becomes highly acidic, leading to rapid decalcification. Once braces are removed, these decalcified areas appear as permanent, opaque white spots.
Vaping also severely compromises gum tissue health, which is foundational to successful tooth movement. Nicotine is a known vasoconstrictor that narrows the blood vessels. This restriction reduces blood flow to the gums, starving the tissue of necessary oxygen and nutrients.
The diminished blood supply impedes the healing response, making the gums more susceptible to gingivitis and periodontitis. The vasoconstrictive effect can also mask the signs of gum disease, such as bleeding. This suppression of inflammation can lead to gum recession and unchecked infection, further complicating controlled tooth movement.
Prolonging the Treatment Timeline
The compounded effects of hardware failure and biological damage directly impede the efficiency of orthodontic treatment, often resulting in a significantly extended timeline. Orthodontic forces rely on a healthy foundation of bone and gum tissue to move teeth predictably and consistently.
When nicotine restricts blood flow, the necessary bone remodeling process—where bone is broken down and rebuilt—is slowed down. If the gums become severely inflamed or infected, the orthodontist may be forced to pause or slow the rate of tooth movement entirely. Continuing to apply force to compromised tissues risks permanent damage, necessitating a delay until gum health is restored.
Each instance of a loose bracket requires an unscheduled appointment for repair, setting back the overall treatment progress. The combination of slower tissue response, frequent mechanical repairs, and accelerated gum disease means the patient’s time in braces is inevitably longer than projected. Compromised gum support also increases the likelihood of teeth shifting back toward their original positions, known as relapse, even after the braces are removed.
