New toothpaste repairs enamel and treats cavities

Researchers have created a natural product that has, in trials, been proven to both repair enamel and treat cavities, and they claim the compound could even be added to toothpastes and mouthwashes.

Scientists at Washington University created peptides – short chains of amino acids – derived from amelogenin, a protein crucial to forming enamel.

Erosion of enamel, which is the hardest tissue in the human body, can also lead to the yellowing of the teeth or sensitivity. For severe cases of enamel loss some NHS patients pay £256.50 for veneers or crowns and private practices often charge more.

Professor Mehmet Sarikaya, the lead author of the study, said: ‘Peptide-enabled formulations will be simple and would be implemented in over-the-counter or clinical products.’ Continue reading “New toothpaste repairs enamel and treats cavities”

13 Foods That Can Whiten Your Teeth Naturally

Teeth are always yellowing as part of the aging process so it’s no wonder teeth whitening has become a big industry, and while teeth whitening isn’t harmful when done correctly it can cause tooth sensitivity and soft tissue irritation.

A tooth-friendly diet can help keep your smile bright and your gums healthy so here are 13 natural tooth-whitening alternatives:

1. Oil (sesame oil or virgin coconut oil)
Oil, or more specifically, oil pulling, is when oil is used for gargling, not cooking. Sesame oil or virgin coconut oil is swished around inside the mouth and then spat out after fifteen minutes. As the substance is vigorously “pulled” back and forth between your teeth, the mucous membranes inside your mouth absorb nutrients from it. Sesame oil has omega-3 fatty acids, iron, calcium, and vitamins A, B and E; while virgin coconut oil has antibacterial properties that promote healthier gums and cavity-free teeth. Just make sure not to swallow any of the spittle that will form as you gargle.

2. Strawberries
Malic acid is a natural astringent that acts as a bleaching agent, and it is present in most commercially available tooth-whitening products. Strawberries are filled with this key ingredient, which will whiten your teeth naturally, so make sure to add them to your basket on your next trip to the farmer’s market. The vitamin C in strawberries also aids in removing plaque.

3. Apples
Apples also contain high levels of malic acid. The act of biting and chewing on this crunchy fruit gently scrubs away debris, stains, and bacteria from your mouth. Continue reading “13 Foods That Can Whiten Your Teeth Naturally”

Toothpaste alone does not prevent dental erosion or hypersensitivity


The rising prevalence of dental erosion and dentin hypersensitivity has led to the emergence of more toothpastes that claim to treat these problems. While no such toothpaste existed 20 years ago, today, many such brands are available.

However, a study conducted at the University of Bern in Switzerland showed that none of the nine analyzed toothpastes was capable of lessening enamel surface loss, a key factor in tooth erosion and dentin hypersensitivity.

The article published in the journal Scientific Reports stated that all of the tested toothpastes caused different amounts of enamel surface loss, and none of the toothpastes afforded protection against enamel erosion and abrasion.

Drinking wine may protect teeth


Drinking wine may protect teeth by destroying bacteria that cause cavities and gum disease, new research suggests.

Despite many dentists warning that alcohol’s acidic content can damage teeth, a study released this month suggests antioxidants in wine significantly prevent bacteria that cause plaque, cavities and periodontal disease from sticking to gums.

The latest discovery could lead to the development of ‘wine-inspired’ toothpastes and mouthwashes that contain such antioxidants, according to the Spanish researchers. Continue reading “Drinking wine may protect teeth”

Teeth regeneration one step closer

A team of researchers believe they have discovered a way to trigger teeth regeneration which would allow them to regrow and even fix cavities.

The team from King’s College, London, conducted a study last year where they showed that mice teeth could be treated with various drugs to trigger the teeth to rebuild themselves. The treatment involves using a series of drugs to activate stem cells at the base of the tooth, called the tooth pulp. Stem cells, which can transform into almost any other cell, then begin to regrow the parts of the teeth that have been lost to accident or decay.

Retainers could contain dangerous bacteria

A report in the journal Letters in Applied Microbiology highlighted the risk of not cleaning retainers thoroughly.

The researchers were looking for microbes not normally found in the oral cavity – particularly Candida and Staphylococcus, including MRSA.

They found that 66.7 percent of retainers and retainer-wearer mouths contained potentially dangerous microbes Candida and about 50 percent contained Staphylococcus. These microbes were present on the interior cheeks and tongue of retainer wearers, living in biofilms which are densely packed communities of microbial cells that multiply on living or inert surfaces within secreted polymers.

Our teeth may come from ancient fish scales


The teeth in your mouth have their origin in the scales of primitive shark-like fish, new evidence suggests.

Sharks and related fish lack bony skeletons and have skin containing tooth-like, spiky scales called dermal denticles.  “Stroke a shark and you’ll find it feels rougher than other fish, as shark skin is covered entirely in dermal denticles,” said Dr Andrew Gillis at the University of Cambridge.
