Scientists reveal the secret of protecting teeth from sweets

Sweet attack on teeth: microbiologists unveil the secrets of cavity formation

As reported by TUT.AZ with reference to The Conversation portal, scientists have detailed the invisible battle that unfolds in the mouth after each sweet treat.

Surprisingly, just minutes after sugar enters the oral cavity, the bacterial inhabitants of teeth begin a real feast, using the sweet fuel for active reproduction and energy production. In just a couple of minutes, the acidity in the mouth reaches critical values that can literally dissolve the protective tooth enamel. The key destroyer is precisely the acids, not the sugar itself.

The body immediately activates defensive mechanisms: saliva tries to wash away sugar and neutralize the acid attack, while friendly bacteria engage in combat with harmful ones. However, with frequent sweet snacks, this defense system simply cannot cope with the load.

A particular danger is the ability of cariogenic microbes not only to feed on sugar but also to create real defensive structures from it – sticky biofilms that firmly attach to the teeth. These natural "fortresses" are practically impossible to destroy without mechanical cleaning. Under such protection, bacteria continue their acid attack, gradually destroying the dental tissue until a painful cavity appears.

Microbiologists recommend simple but effective protective measures: consume sweets during main meals when saliva is actively produced; avoid sweet snacks between meals, which create an ideal environment for bacteria; don't neglect regular oral hygiene, including thorough cleaning of teeth and interdental spaces, which helps to promptly remove dangerous plaque.
