There is growing clinical and scientific evidence that orthodontic aligners and retainers can contribute to increased risk of dental decay (caries) and enamel demineralization—particularly when oral hygiene and pH control are inadequate. Below are key studies and findings supporting this concern:
Orthodontic aligners and retainers:
Dental professionals may consider recommending:
Given the increased risk of enamel demineralization, low salivary pH, and microbial shifts associated with orthodontic aligners and retainers, applying a pH-buffering gel like pH7Smile inside the appliance before sleep may offer meaningful protection.
While the formula is a proprietary blend the Hydroxyapatite level is within the recommended range by the manufacturer for a dental product. The gel is designed to be worn overnight and for some time during the day in higher risk situations.
The gels are formulated to be in the neutral range which is pH7. Note some products on the market that are used for cleaning retainers and aligners are acidic and use during wear seems to be a questionable suggestion by these companies.
Patient Consent Script (revise to suit) – Dental Appliance Use & pH Protection
"As part of your dental or orthodontic treatment, you're wearing a dental appliance such as a retainer, aligner, night guard, or snore guard. Please be aware that wearing these appliances—especially overnight—can increase the risk of tooth decay, enamel demineralization, and white spot lesions, particularly if oral hygiene or pH balance is compromised. Certain medical conditions and habits can increase complications with dental appliances - especially if you have dry mouth and/or acid reflux.
To help reduce these risks, we recommend using a pH-protective gel like pH7Smile during appliance wear days/nights depending on your decay risk level, medical status and oral hygiene level. These pH-protective gels may help neutralize acidity, reduce harmful bacterial levels, clean your appliance, support enamel health, and reduce the chance of complications. The cost of protective gels and appliance replacement is above the original fee."
