A Guide for Those Who Care about Their Smile


Stewed and Roasted Vegetables Can Harm Our Teeth

The Naked Chief Jamie Oliver made the people throughout the world like vegetable stews and oven roasted vegetables. If cooked with love, such meals are very tasty and, in addition, they are considered to be very healthy and useful for our body. In particular, stewed and oven-roasted vegetables are beneficial for our digestive system. However, according to a research carried out two years ago by a group of specialists at the University of Dundee, Scotland, eating a lot of stewed and oven roasted vegetables can be harmful to our teeth and stimulate tooth decay.

The researchers were analyzing chemical content of stewed vegetables cooked in oven for 45 minutes and in a traditional way (boiled in a pot on the top of the stove). They discovered that stewed squash, eggplant and green belly pepper have increased acidity, which can be compared to the acidity level in sodas, the most powerful destroyers of human teeth. Red peppers should be also associated with increased acidity and negative effects on our teeth enamel. At the same time, such vegetables as tomatoes and onions do not have high acidity levels whatever way of cooking is chosen.

“The acidity of ratatouille prepared by oven roasting is the same as that of some carbonated drinks that, when consumed in excess, are believed to contribute to the development of dental erosion,” Dr Graham Chadwick of the School of Dentistry, one of the leaders of the research, comments. The results of this interesting study were published in 2006 in European Journal of Prosthodontics and Restorative Dentistry. Acid erosion is one of the most common and dangerous dental conditions which affects modern people of all ages.

A Revolution in Dentistry: Decayed Tooth Enamel Regowth

A group of Australian specialists from the Cooperative Research Centre (CRC) for Oral Health Science, leaded by Professor Eric Reynolds and Dr. Nathan Cochraine, recently came up with a new technology in tooth enamel restoration. This innovative approach can help to re-grow enamel of a decayed tooth, this way giving an opportunity to avoid using filling, and possibly prevent and even reverse tooth decaying process. Many experts are convinced that this promising technique should be considered a new revolutionary breakthrough in modern dentistry.

The treatment includes application of a strong solution (containing such elements as calcium, fluoride, phosphate and other constituents) on the affected tooth and keeping the solution overnight. “The localised application of the mineral treatment re-grows the crystals of the tooth, repairing damaged tooth enamel,” Nathan Cochraine comments in the results of the hard work. At that, the specialists used only natural materials derived from cow’s milk for preparing the solution. The ions of natural calcium, phosphate and fluoride can be stabilized and encouraged to diffuse into the enamel, improving the quality of the crystal lattice.

There is no need to mention new opportunities and horizons for the humanity which can be opened due to this innovative technique. “Dentists who have patients showing signs of early decay will be able to prescribe the nightly use of the remineralisation treatment for a given period, potentially avoiding treatments such as fillings and extractions,” the specialists underline. The invention is expected to be presented soon at the international conference the Pathfinders: the Innovators Conference at the National Convention Centre in Canberra.

Tooth Staining and Discoloration

Staining and tooth discoloration are among the most common aesthetic dental problems which in many situations are quite hard to get rid of by using only natural or home-made remedies. It is a known fact that a lot of people have naturally yellowish or slightly gray shades of their teeth, and up-to-date cosmetic dentistry can offer several effective treatments of such problem, including various teeth whitening procedures, tooth bonding, dental crowns and veneers, etc. Such procedures are very popular and demanded nowadays since every modern person dreams about having a perfect smile.

There are various reasons of staining and discoloration, which include, first of all, poor oral hygiene and constant exposure to so called chromogenic agents, such as coffee, tea, cola, tobacco and other products. Regular users of such products have staining effects on their teeth. Also, this problem can be cause by aging, using low quality mouthwashes and certain medicines which affect the enamel (in particular, some antibiotics), excessive amounts of fluoride (especially in children) and other factors.

Modern specialists define two types of dental staining. Outside (or extrinsic) stains are the pigment that are located on the surface of the teeth. They are usually caused by smoking, drinking too much of tea, coffee,  cola, etc., or as a result of a chemical reactions with some medicines. Extrinsic stains can have a variety of shades, starting from dark and greenish (tar strain) and ending with orange and yellowish. As a rule, outside stains can be easily bleached away, polished or removed by using other dental cleaning procedure.

Inside stains are connected with the staining inside of the tooth anatomy. Since such staining occurs much deeper in the tooth structure, it is usually much harder to combat with. Such type of straining usually has more serious effects on the teeth and can be caused by many reasons, such as worn out tooth enamel, excessive fluoride ingestion, traumas, bacterial infections or using some medicines (Tetracycline, Minocycline, etc). Heredity also plays an important role in developing inside stains.

According to recent studies, modern women are less commonly affected by tooth staining than men. However, it is necessary for every modern person to remember that such problem as tooth staining and discoloration can be prevented by following very easy and healthy principles of good dental care. Use whitening chewing gum, brush and floss your teeth on a regular basis, visit your dentist every six month for a check-up and use professional dental cleaning on time. This way, your teeth will be always white and shiny, and your smile will always be bright and attractive.
