An orthodontist explains what his wife discovered after trying pH7Smile (a Retainer Gel product).
Acidic conditions build fast — and traditional measures do not address the highest risk of damage during the night.
As aligner therapy 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:
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 pH7 Smile employs a very special nano hydoxyapatite (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.

NOTE: Xylitol is in the original pH7smile and Monk fruit extract is used in the Hydroxyapatite formula along with clove oil.
Patients are given dental appliances every day and even with perfect home care there are various factors that turn the environment inside a dental appliance into a war zone.
Studies show the lack of saliva flow allow harmful bacteria a chance to increase in number, overpowering the healthy strains that are more important than previously understood. It appears that the goal of killing nearly 100% of the 'bugs' as claimed by many dental health products may have negative health side effects including a higher incidence of diabetes. Our two product versions of pH7Smile use a patented combination of natural ingredients including baking soda to reduce the harmful bacteria and help control acidity.

Teeth decaying under dental appliances? (2025)
Millions of people are instructed to wear dental appliances including:
Patients also have various medical conditions that increase acidity and dry mouth which amplifies the need to consider not just the blockage of normal saliva flow but protection from less than ideal conditions.
Simply apply to inside of appliance and wear as usual, spit excess, rinse out with cold water in the morning or as otherwise directed.
The dental harm from acid reflux can occur even in people with excellent home care. Many do not even know they have the condition and when wearing an appliance the stomach acids can slip under appliances and destroy the teeth. Our baking soda formulation helps to neutralize acidity and maintain a pH of 7 inside the appliance.
Hundreds of medications and recreational drugs (marijuana) cause dry mouth which increases tooth decay. Various medical conditions such as Sjogren's and Diabetes -even aging - also cause a dry mouth. The optimized natural additives and baking soda in our product are the perfect combo to add to the typical regiment of high fluoride toothpaste brushing, flossing and tongue scrapping.
Mouth Breathing also causes a dry mouth and lowers pH into the acidic zone according to a recent study increasing the risk of tooth decay:
Radiation and chemotherapy often disturbs the natural production of saliva and the body's defense systems. Protective appliances can be fabricated specifically for use of pH7Smile and any existing appliances can essentially be turned into protective carriers of our gel.
Various eating disorders often involved vomiting and serious dental complications. A possible use for reduction of harm is pH7Smile with extended clear trays that physically and chemically shield the teeth from acid exposure.
If you are a patient whose dental professional does not provide this product you can order pH7Smile without a prescription but you are encouraged to discuss your situation with your trusted health professional. Check out our new whitening gel!
