Study Shows that Cavities are Contagious

Cavities are Contagious

A recent study by the University fo Louisville in the United Stated has shown that cavities are contagious.

Cavities are a common dental condition, and now they are proven to be infectious. Common causes for transmission of the bacteria which causes cavities are parent to child infections. Parents who clean their child’s dummies in their own mouths or share spoons whilst feeding increase the risk of transferring oral bacteria which can erode teeth and cause cavities.

The study recommends good oral hygiene for both parents and children. Children especially are to be registered with a dentist as soon as milk teeth start to grow. Parents are encouraged to maintain their own oral health and observe that of their child to prevent infection and development of cavities.

Chemicals in Plastic and Fungicide May Cause Irreversible Damage to Kid’s Teeth

chemicals plastic fungicide irreversible damage kids teeth

A study conducted by the French National Institute of Health and Medical Research (INSERM) presented to the European Congress of Endocrinology has concluded that chemicals found in plastic and fungicide may be causing irreversible damage to children’s teeth. The chemicals are classified as “endocrine disruptors” (ED), and are responsible for interfering with hormones which encourage the growth of new tooth enamel.

Amongst the chemicals which were identified, two are worryingly common: Bisphenol A (BPA) can be found in plastic items such as food storage containers, lunch boxes and drinks bottles. Vinclozolin is a fungicide which is often used in vineyards, orchards, and even golf courses. Exposure to both these chemicals can inhibit the body’s ability to produce enamel. The oral condition Molar Incisor Hypermineralisation (MIH), where teeth are more susceptible to cavities may be linked to exposure to these ED chemicals. 18% of children aged 6-9 suffer from MIH.

Lead author of the study, Dr. Katia Jedeon said: “Tooth enamel starts at the third trimester of pregnancy and ends at the age of 5, so minimising exposure to endocrine disruptors at this stage in life as a precautionary measure would be one way of reducing the risk of enamel weakening,”

Antidepressant Link to Dental Implant Failure

Antidepressant Link to Dental Implant Failure

Recent research by the University at Buffalo School of Dental Medicine has shown an antidepressant link to dental implant failure. The recent findings back up a report in 2014 by McGill University researchers who reported finding a link between Selective Serotonin Reuptake Inhibitors (SSRI) antidepressants and a doubling of the risk of dental implant failure.

Implant failure amongst antidepressant users were about four times higher compared with controls in the study. The higher rate of failure is linked to how antidepressants affect bone metabolism/growth and heighten the risk of dry mouth (clinically known as xerostomia). These side effects contribute to the failure of dental implants as the mouth fails to heal properly. The researchers also that each year of antidepressant use doubled the odds of failure.

Additional side effects of antidepressants include osteoporosis, akathisia (a disorder with the symptoms of needing to be in constant motion), and teeth grinding. All of these can contribute to dental implant failure.

Researcher Sebastiano Andreana, Associate Professor and Director of Implant Dentisry said: “Antidepressants are the second most prescribed drug in this country, and there are millions of implants placed every year around the world, so this applies everywhere, not just the U.S.”

Bearing this in mind, the researchers stress that communication between dentist and patient is of especial importance. Researcher and Clinical Assistant Professor Dr. Latifa Bairam said, “For patients who have been on antidepressants a long time, we’re not telling them to quit their medication. We just want them to be aware — the dentist, patient, and physician. It’s cooperation between all the parties to manage the procedure.”

“It would really be useful if patients provided the dentist with a current picture of lab tests, which would be helpful in treatment planning for the placement of the implant,” Dr. Bairam concluded.

What Causes Discoloured and Stained Teeth

Discoloured and Stained Teeth

Knowing what causes discoloured and stained teeth helps to keep your smile whiter for longer. You are also highly encouraged to avoid staining consumables if you have had teeth implants, teeth whitening, or significant cosmetic dentistry work. If you’ve noticed your teeth becoming discoloured, or have just had a cosmetic dental procedure, then bear in mind the following elements which cause discoloured and stained teeth:

Age – Enamel on teeth wears down with age. Erosion can lead to crevices where stains and discolouration can occur. A good dental care routine can help slow down the erosion process, but if the problem with discoloured and stained teeth persists and even gets worse, then restorative dental procedures such as enamel restoration or implants could be a consideration.

Smoking – As we pointed out previously, not only is smoking a main cause of bad breath, it can also stain teeth. Along with the health benefits, quitting smoking gives your teeth a break from exposure to a discolouring habit, as well as being a benefit to the rest of your body

Food – Berries (including cherries), beetroot, curries, tomato sauces and pickles are either acidic or staining. If you can’t live without blueberries or borscht, then rinse your mouth with water shortly after eating them.

Drink – Tea, coffee (both especially when drunk without milk), red wine and acidic fruit and fizzy drinks are full of staining tannins and also acidic, which affects the integrity of your teeth’s enamel. White wine is not as bad for discolouration, but contains an equally damaging amount of acid.

Condiments – Ketchup, soy sauce and balsamic vinegar are either acidic or highly staining. If it stains fabric, then it can stain your teeth!

Artifical and natural colours – It may seem obvious, but colourings in food and drink are often overlooked. Especially bad for causing discoloured and stained teeth are products like sweets (if it turns your tongue an unnatural colour, your teeth are equally at risk) and frozen ice products. If it had added colours, then they could end up on your teeth.

Interview with Dentist who Fixed Shane MacGowan’s Teeth

It’s the fairytale of Shane MacGowan’s teeth! The singer is famous for the terrible condition of his teeth, which became ravaged and almost non-existent after decades of rock and roll excess coupled with an extreme lack of dental care.

During the last week of of November, MacGowan attended an after-party, where he was pictured with a completely new set of teeth, including a decorative gold front tooth.

The change is remarkable, but the real hero of the story has to be the dental surgeon Darragh Mulrooney, who carried out the nine-hour dental implant procedure assisted by an expert team.
