Could YOU Be Neglecting the Rise in Decay Under Aligners and Retainers?
Acidic conditions build fast — and traditional measures do not address the highest risk of damage during the night.
As aligner therapy, such as Invisalign, becomes more popular, so does a silent but serious concern: rising enamel damage during treatment. Aligners and retainers do more than just trap plaque — they magnify the acidic environment around the teeth. Saliva can’t neutralize acids when aligners are sealed in place — especially overnight.
And while patients brush, floss, and rinse during the day, traditional measures do not address the highest risk of damage during the night. This is where pH7Smile Appliance Gels come in.
Formulated specifically for use inside aligners and retainers, pH7Smile is available in two bioactive options:
- Nano-hydroxyapatite + baking soda — for remineralization and buffering
- Xylitol + baking soda — for acid neutralization and bacterial interference
Both work silently while patients sleep, helping protect enamel, reduce sensitivity, and buffer acids in the very places hygiene can’t reach. If you’re not yet addressing the acid entrapment risk that aligners create, you may be overlooking a critical point of failure — and a powerful opportunity to elevate your standard of care. Our two pH7Smile gels include the original xylitol-baking soda (X for short) and the new nano-hydroxyapatite-baking soda version (HA). The xylitol-free version of pH7Smile employs a very special nano hydroxyapatite gel (nanoXIM CAREPASTE).
While there was some negative press concerning xylitol safety in June 2024, a closer look at the studies found the doses of concern were the equivalent of consuming a bottle of our gel every day. Advocates of xylitol still feel it is a worthy ingredient for dental health products as an alternative to fluoride, which some want to avoid. Our initial concerns with xylitol after reading the sensationalized headlines now appear unfounded, and lower dose xylitol products are considered safe.
Recent news:
A prominent US orthodontist university is evaluating pH7Smile for a potential study of its benefits and potential reduction of risks from clear aligner therapy. A top Sjogren's dental specialist proposes a study to substantiate the application of pH7Smile for dry mouth sufferers who have magnified dental risks.
