How to prevent cavities

To prevent cavities, you must create an oral environment that makes it difficult for infectious cavity-causing bacteria to survive

Brushing and flossing alone may not be enough to prevent decay

Stop the infection with new fluoride, xylitol, and alkaline pH+ dental products

Cavities are the demineralised areas, or holes, that form in teeth as a result of a bacterial infection called dental caries. This infection takes place when the normal healthy bacteria in the mouth are replaced by acid-producing bacteria. This shift in bacteria is primarily cause by two things:

Prolonged acidic oral environment: contributing factors include, a lack of saliva, and/or a sugary/acidic diet that favors acid-producing bacteria.
Transmission: this infection is contagious! You can be infected by someone through the exchange of saliva.

Visit a dentist who is performing "caries risk assessment", where they evaluate whether you have factors present that can put you at risk of decay.

Have regularly scheduled hygiene appointments, exams, and perform daily brushing and flossing at home.
Limit not only sugary/carbohydrate containing items in your diet, but also even non-sugar containing acidic beverages (diet soda, coffee, tea, sparkling water, alcohol).
Consider the acidity (pH) of the dental products you are using.

Do they neutralise your mouth?

Know your pH.

Don't just brush and floss. . . neutralise!

Xylitol is a very effective agent for limiting the acids produced by bacteria and comes in a variety of gums, wipes, sprays, rinses, toothpastes, etc.

Using products with xylitol and an alkaline pH, in conjunction with fluoride, may be the most preventive method.

Keep the pH in your mouth neutral, especially after eating.
