   Tooth Decay Can Be Contagious？

SEASON SUMMARY

We always think that tooth decay is just the result of careless brushing, but studies have revealed the shocking truth - tooth decay is a "contagious" disease! Even in the same person's mouth, a single decayed tooth can trigger a "domino effect" and infect multiple teeth!


Scientific research has found that:

Caries-causing bacteria can be spread through saliva (such as sharing tableware and kissing).

A decayed tooth may trigger a "chain reaction", causing adjacent teeth to fall one after another.


Today, we will reveal this easily overlooked health hazard and teach you how to build an "anti-caries firewall"!


What is Tooth Decay？

What is tooth decay?

Bacteria's Sweet Trap

Tooth decay is medically known as dental caries. The truth behind it: a "sweet trap" for bacteria. Do you think tooth decay is just bad teeth? In fact, it is the bacteria in the mouth that are causing the damage!


There are many kinds of bacteria in the mouth, among which Streptococcus Mutans and Lactobacillus are the main pathogens that cause dental caries.


01

The Culprit of Tooth Decay

? Streptococcus Mutans（Most wanted）

? Lactobacillus（Accomplice）

02

The Process of Tooth Decay Crime

1

The sweets you eat become a delicious meal for bacteria

2

Bacteria break down sugar and produce "acid bombs"

3

Acid erodes tooth enamel, eventually forming "small black holes" (cavities)

Tips: Tooth enamel is the hardest substance in the human body, but it succumbs to the acidic attack of bacteria!

How Is Tooth Decay Transmitted?

How is tooth decay transmitted?

Bacteria's siege war!

Do you think tooth decay is just a problem for a single tooth? Wrong! These bacteria are much more cunning than we think!

Dual channels of transmission

Human-to-human: Spread through saliva contact such as sharing tableware and kissing

Tooth-to-tooth: A decayed tooth can become a "military base" for bacteria


Bacteria's battle plan
1?? The vanguard captures a tooth (Causing a cavity)

2?? Establish a "logistics supply station" in the wormhole (food residue + humid environment)

3?? Use the cavity as a base to launch a full-scale attack on the neighboring teeth!

?? What's even more terrifying：
If left untreated, these bacteria can spread like wildfire from one tooth to your entire mouth!

How Does Tooth Decay Form

How does tooth decay form

The three main causes of tooth decay

Tooth decay doesn’t happen overnight! There are three main accomplices behind it:

01

Bad oral hygiene habits

? Skipping the toothbrushing routine, bacteria are having a party.

? Without using dental floss, food residues "settle" in the gaps between teeth.? Not having regular dental cleanings leads to the accumulation of plaque, forming "bacterial fortresses" on the teeth.

02

Eating habits

? Sweet lovers, pay attention! Sugar is the "food" for bacteria.

? Carbonated drinks = An acid bath for the teeth

? Frequent snacking leads to the oral cavity in an "acid erosion state" for a long time.

03

Tooth structure

? Deep fissured teeth: The natural "bacteria parking lot"

? Malocclusion: Hidden areas become "bacterial refuges"

? Dental enamel deficiency: Carrying "defensive vulnerabilities"

Oral Protection Plan

Oral protection plan

01

Fluoridization

? Fluoridization：The "effective tooth-fighting helper" that is a must-learn for dentists

I-ReHealth Fluoride Products：Fuloride varnish, Colafluor fluoride varnish, fluoride foam, copal fluoride varnish...

02

Pit and fissure sealing

? Pit and fissure sealing：Put on a "protective shield" on the molars


It is essential to complete the three stages of pit and fissure sealing.

? 2 to 3 years old, after the primary molars erupt

? 6 to 7 years old, after the six primary tooth emerges

? 11 to 13 years old, after the second molar erupts

I-ReHealth pit and fissure sealant:

? Light-curing color-changing and visualized operation

? High bonding strength

? With fluoride formula..., long-lasting protection for teeth

03

Habit formation

? Brush your teeth with fluoride toothpaste in the morning and evening, and make sure to clean them thoroughly.
