Tea Effect on Teeth

Not all drinks are good for our teeth. Besides sugar it is the PH value of some drinks that has negative effects on your teeth. People who have abandoned their morning cup of coffee for a healthier cup of herbal tea might want to think again, say British researchers. They found that many herbal teas seriously damage teeth by eroding protective enamel.

Not all drinks are good for our teeth. Besides sugar it is the PH value of some drinks that has negative effects on your teeth.

All warm Pickwick teas, also the fruit flavoured teas, are pH-neutral and do not effect the dental enamel. Therefore, tea is not only a delicious drink, but also a drink that can be drunk all day long.

One cup of tea contains approximately 0.25 milligrams of fluoride. Fluoride is well known about its positive effect on teeth. One’s daily fluoride need is somewhere between 1.4 and 1.5 milligrams. Thus tea consumption also contributes to meet our fluoride need.

People who have abandoned their morning cup of coffee for a healthier cup of herbal tea might want to think again, say British researchers. They found that many herbal teas seriously damage teeth by eroding protective enamel. “Many of the herbal teas tested were found to be more erosive than orange juice,” University of Bristol researchers report in the Journal of Dentistry. Some teas were three times as acidic as juice. A spokesman for Twinings teas says saliva dilutes and neutralizes any acid in herbal teas, adds The Week magazine.

What’s your poison, coffee or tea? Most adults prefer one or the other. After all, caffeine is a super pick-me-up. Hot or cold, black or doctored, our favorite daytime drinks are laced with it.

However, our best beverages can wreak havoc on our beautiful smiles. Like tobacco, coffee beans, tea leaves and even colas can stain teeth brown. The more you sip, the more they stain.

Some people stop taking tea after their dentist asked them if they smoked because of teeth stains. Well yes, tea does stain. It contains tannic acid. You’ll have an idea when you see the thin film on the surface of cold tea. Coffee, red wine and fruits such as apples and blueberries also contain this chemical and can stain teeth.

Effect of Black Tea on Teeth

Dental caries is the prime cause of premature loss of teeth in children. Tea contains high percentage of fluoride along with polyphenolic constituents which act on GTF of S. mutans in plaque synthesis. Combination of fluoride and polyphenolic constituents inhibit caries activity.

Herbal Tea May Damage Teeth – Study

Drinking herbal tea may damage teeth by eroding enamel, the results of a new study indicate.

Researchers analysed the erosive potential of a variety of herbal teas by measuring their pH levels, which shows whether a substance is acid or alkaline. Acidic substances are known to damage teeth. The ability of the herbal teas to erode enamel was also measured. Enamel is the hard, white, outer layer of the tooth.

The study found that while some of the herbal teas had high pH levels, indicating that they are alkaline and do not damage teeth, many of the teas tested had low pH levels, which means that they are acidic and can damage teeth.

“Many of the herbal teas tested were found to be more erosive than orange juice”, the researchers from the University of Bristol Dental School said.

“Many studies show a high prevalence of tooth wear, even in young patients. One factor that may be contributing to this problem is the consumption of herbal teas that are often considered to be ‘healthy’ alternatives to other beverages”, the researchers added.

Dentists treating patients with enamel damage should advise their patients of the potential risk of some herbal teas, they also said.

Something To Smile About – Tea And Teeth

Tea is not only a delicious drink. Drinking tea is good for your teeth!

“Drinking tea may ward off tooth decay.”
A study suggests chemicals in tea can destroy bacteria and viruses that cause throat infections, dental caries and other dental conditions. It raises the prospect of adding tea extracts to toothpaste and mouthwash to protect the teeth.

It found that caffeinated green tea was the best at fighting viruses, followed by caffeinated black tea. Decaffeinated blends were less effective as anti-viral agents.

Tea-drinkers beverage of choice contains fluoride, a mineral that strengthens tooth enamel and guards against decay. Studies also show that tea may reduce dental plaque and bacteria in the mouth, thereby helping to prevent cavities and gum disease. Green tea contains a bit more fluoride than black, but a few cups a day of either may help to save you from the dentist’s drill. “It’s important to choose a healthy diet, and that includes beverages,” says Blumberg, noting that Americans tend to opt for drinks with no nutritional value. “If it’s a choice between soda pop or [freshly brewed] iced tea – and you’re looking for the healthful choice – it’s a no-brainer.”

Apparently drinking tea (without sugar, naturally) has a number of beneficial effects in preventing tooth decay. Many of the natural properties of tea, especially fluoride, which has been absorbed from the soil by the tea plant, contribute towards oral hygiene and a reduction in dental erosion.

And if you’re not a dentist, then that simply means, it helps prevent stinky breath and those who are dentists from shoving whirling drills into your mouth while grinning manically.

Another tea study found that polyphenols–chemicals found in tea–can help prevent bad breath. Laboratory experiments revealed that polyphenols can retard the bacterial growth that causes bad breath.

  1. it is amazing to read this research finding! and more strangely the latest finding that chocolate can prevent tooth decay!

  2. Hi. I was wondering if " Lipton Green Tea " hurts your teeth cause my mom drinks it and I was wondering. Thanks, Amanda

  3. I prefer to drink green tea everyday, so it's good news for me to read.

  4. If you're talking about the bottle Lipton Tea, then odds are yes. Aside from the newer version that they are rolling out which claim to be made from real tea leaves the tried and true Lipton Green tea that we've been drinking out the bottle for years is created chemically. It also has a variety of citric acids in it that would aid in erosion just like lemon or orange juice would.
