This might have been the most important information for my dental health I ever came across: Two dentists have written a book with the provocative title “Zahnarztlügen” ( Dentist lies, available only in German). In their book they list the following statements as not true :
- Caries is not curable
- Brushing teeth prevents caries
- One must see a dentist
- Professional tooth cleaning protects from caries and periodontitis
- Flossing protects from caries
- Fillings protect from caries
- Bleaching and whitening toothpaste are harmless
- Teeth decay anyway
- Caries and periodontitis are unavoidable
- Third molars can move front teeth
They cite a number of studies as proof for their claims. The cited studies are listed below. They say 95% of Germans are suffering from caries although they brush their teeth daily and visit their dentist regularly. Germans are spending more money on dentists than anybody else on the planet. They also say that dentist visits carry a high risks. That I can confirm, during a normal check up I catched the worst gingival infection of my entire life and then the dentist sent me from one expert to the next. It had cost me a fortune.
Unfortunately this information comes a bit late for most of my teeth, the good news is that existing caries can even be reversed, the enamel can be remineralized.
The biggest surprise was this study :
“since self -flossing has failed to show an effect”
Scientific study on CHX:
With respect to dental hygiene applications, the cationic nature of CHX (Chlorhexidine) enables it to bind to tooth surfaces and oral mucosa, reducing pellicle formation and increasing substantivity through controlled release of the agent (2). The efficacy of CHX in reducing oral bacterial viability (14, 36, 42), strongly inhibiting plaque regrowth, and preventing gingivitis (25) has been demonstrated in many studies (7). Relatively few investigations have considered longer-term effects of CHX use. An early study, however, demonstrated that oral treatment of human volunteers with CHX resulted in a 30 to 50% reduction in total bacterial counts with an associated reduction in counts of Streptococcus mutans (38).
Apparently two inexpensive measures can protect my teeth better than brushing and flossing :
Take 5g – 10g Xylitol every day by chewing a Xylitol containing chewing gum or lozenge
Mouthwash regularly 2 minutes with Chlorhexidine gluconate 0,2%
Staines can be removed by brushing teeth with sodium bicarbonate (baking soda)
