I was previously told by my dentist that tea contains high fluoride, therefore drinking more of it (without sugar) can help protect teeth from caries.
On the other hand, as many people prefer to drink tea with sugar, that may enhance the bacteria causing the dental problems.
Any scientific evidence if tea is good or not for the dental hygiene?
Tea contains antibacterial materials especially green tea in addition to fluoride
Green tea contains tannin which is vasoconstrictive material and effective in stopping bleeding
Dear Hani,
this is an interesting question. Of the many benefits of tea, idid not know that this was one of them. I do not know if fluoridated water is necessary, but it would be an enhancement. I am sending 2 links. Green and oolong teas fight cavities.

Tea is known to contain tannins and fluoride which have an anticariogenic potential. However, most people consume tea with milk and sugar which are both detrimental to the cause.
Furthermore, excessive consumption of tea causes stains over a prolonged period of time.
Researches have shown that tea certainly possesses significant anti-cariogenic properties by virtue of the various anti streptococcal actions and a very high quantity of fluorides in it.
Tea “can be considered a functional food for oral health by controlling, through prevention, the most prevalent infectious disease of mankind: Caries. the fact that the incorporation of tea extract in dental products such as dentifrices, mouthwash, dental floss, and chewing gums can prove to be helpful in prevention of dental caries.
Dried tea leaves contain between 82 and 371 µg F/g (25). Preparation of tea infusions by adding 1 g of the tea leaves (contain an average of 225 µg F/g) to 100 mL deionized water preheated to 85°C resulted in an average of 1.49 ppm F (25). The intake of 250 mL (~1 tea cup) of tea leaves infused in tap water contains 0.7 ppm will expose the body to 0.55 mg F, with F concentration 1.7 ppm. If a 7-year-old child (~23 kg) drinks 250 mL tea infusion prepared in water contained 0.7 or 1.5 ppm, the body will be exposed to 0.55 or 0.75 mg F, which accounts 40 % or 54% of the average optimum daily F intake (0.06 mg F/ kg body weight). Drinking tea brewed in sub-optimal F level is systemically beneficial during teeth development up to the age of 5 years. Tea drinking also exert local effect by increasing saliva and plaque F concentrations. Excessive tea dinking brewed in above optimal F level may associated with dental fluorosis.
Tea does not affect the development of caries. Fluoride does not protect teeth from caries and as a toxic substance, with uncontrolled consumption leads to unexpected results. Caries develops inside the tooth, and not outside the tooth. Bacteria, the amount of which increases with caries and periodontitis, feed on dead cells and blood, rather than sugar.
