American researchers link oral bacteria to colon cancer progression


Researchers in America have established a link between a form of common oral bacteria and the acceleration of colon cancer.

A team from the College of Dental Medicine at Columbia University found that a common strain of oral bacteria, which is linked to tooth decay, can also contribute to colon cancer progression. F.nucleatum, which is often found in dental plaque, could play an instrumental role in the pace of colon cancer growth. Colon cancer is currently the second deadliest form of cancer in the US.

Yiping H Wan, study leader and professor of microbial sciences, explained that genetic mutations play a significant role in the development and spread of cancerous cells, but there are other factors to consider, including the presence of microbes. Scientists discovered that around a third of colon cancer cases are associated with the strain, and those were found to be more aggressive than others, but until now, it was not known why this was the case.

In a previous study, Han and his team discovered that the bacterium produced a molecule known as FadA adhesion, which was found to stimulate growth in cancerous cells, but not in healthy tissue. Prof Han wanted to build on the findings of that study and determine why F.nucleatum only triggered growth in cancerous cells. The most recent study focused on this interaction, and researchers found that non-cancerous cells lack a protein called Annexin A1, which stimulates growth. Using in-vitro trials, which were followed by trials involving mice, they determined that prohibiting Annexin 1 function prevented F.nucleatum from binding to cancerous cells. Subsequently, this slowed growth.

In light of their findings, Prof Han and the team are now looking for ways to use Annexin 1 as a biomarker for advanced, aggressive cancers and to utilise the study as a base for developing potential treatment options.

Would you buy a Dyson toothbrush? Innovative inventor reveals latest project

shutterstock_354663890When you hear the name Dyson, you probably think of hoovers, but that could be able to change. Sir James Dyson, one of the world’s most prolific inventors, has revealed that his latest project is a state of the art toothbrush.

The Dyson firm, which is owned by the innovative inventor, has applied for several patents for its new super brush, which features a powerful water jet within the bristles. The aim of the jet is to disperse and remove food debris. The patent applications relate to a “dental cleaning appliance”, which features a delivery system that provides frequent bursts of water to banish bits of food and bacteria. It is also believed that the brushing device could be used as a flossing aid when used without the bristles.

The high-tech brush features a reservoir, which is located between the handle and the brush head. This reservoir is filled with water, which is released when triggered by a light sensor or a camera; this results in several short bursts during brushing. The sensor would ensure that water is released only when the brush is in position between the user’s teeth.

The new brush design also features six modes and the head can oscillate up to 6,000 times per minute. There’s also talk of an additional feature, which prevents brushing too hard, a major cause of enamel wear.

So far, no additional information, such as the recommended retail price or release date, is available.

London Dentist Discusses how to Stop Tooth Decay

Tooth decay is one of the most common dental problems in the world. During eating food particles are left behind in our mouths, these particles can develop bacteria (not all of which is necessarily bad). This bacteria forms a film over your teeth and is called plaque. It is the build up of plaque that is the primary cause of tooth decay. The first effect of tooth decay is the development of small holes in your teeth, known as cavities. It becomes difficult to clean inside these cavities and so plaque is able to continue to developing inside the holes, causing more degradation of the tooth.

Different types of bacteria can cause tooth decay in different manners. One common bacteria is lactobacillus, this bacteria is able to demineralise the enamel and dentin of the tooth, eventually causing very serious problems by killing the root of the tooth. Without any form of treatment tooth decay will eventually lead to tooth loss of one or many teeth. The infection can even spread to your jaw bone where treatments become increasingly problematic.

There are a number of preventative measures that are very effective at keeping tooth decay at bay. Your London dentist cannot stress enough the importance of brushing your teeth at least twice a day, this is the best way of stopping tooth decay from beginning at all since it cleans away all the plaque that builds up throughout the day. Also very important is an interdental tooth cleaning, this normally takes the form of flossing between your teeth where plaque can build up beyond the areas a tooth brush can reach.

 

Watching out for Dental Cavities in the City of London

The top of any dentists agenda in the city of London is to ensure they look after your teeth as best as they humanly can and to advise you how to do the same when your not sitting in the chair, and there are some basic principles applied to this. What you’re trying to avoid in everyday life is the build up of plaque and to keep your teeth clear of acids and bacteria. Do this well and between the pair of you you’ll be avoiding the dangers of dental cavities. These little evils can gather speed quickly, especially if you are pretty nonchalant about oral hygiene and about keeping up with dental check-ups. Acids start to attack the surface of the teeth quickly and then soon eat their way inside. If you go to your dentist regularly, then they will pick up on this and solve the problem with a filling. But, if you get lackluster about things, the first you will know about the cavity is when you get a tooth-ache and at this stage, it literally means that the tooth is dying inside. Catch it at this stage and you will require a root canal, though you will save the tooth. But tooth-aches can go away and you may think ‘no problem’- think again, because the whole root of the tooth will become infected and possibly cause gum disease and then all of your teeth are in peril, as is your general health.

The ongoing fight against Tooth Decay in Central London

Tooth decay in central London is the direct result of poor oral hygiene. In the average diet, the foods will consist of carbohydrates and sugar at some point but it’s vital that they are removed from the surface of the tooth, otherwise, the bacteria and acids that emanate from such foods will start to attack the surface of the tooth and then eat into the tooth itself, causing decay- the teeth are at even further risk if saliva levels in the mouth are low (usually caused by medication, stress and/or diet), as this acts as a natural deterrent to bacteria. Good oral hygiene and regular dental excursions will be enough to thwart tooth decay, mess this up however and the first time you realize decay has set in is when you have a tooth ache- this may be remedied with a filling but if it’s bad, you will require root canal treatment. Any further ignorance towards the problem and the tooth will fall out altogether. Of course the side effects of this can lead to gum disease and then you are in a world of hurt that will take some pretty expensive and extensive treatment to put right if you don’t want to end up wearing dentures.

Caring for your Gums in Central London

One of the main goals of oral hygiene in central London is to ensure that bacteria is not allowed to develop into plaque and tartar around the teeth, for if it does, it can start to infect the gums and lead to tooth decay and loss. Even more serious, if gum disease sets in, it will release toxins into the blood stream that in the long run, can lead to the breaking down of the vital organs throughout the body. So, back to basics: it all starts with the right tooth brush and how to use it to ensure that food doesn’t get stuck around the teeth and gums; a good toothpaste is also essential in counteracting the build up of plaque and for keeping the teeth’s enamel in shape. The use of dental floss and inter-dental brushes are also very good for removing food from the teeth and gums, as is the back-up of mouthwashes. What is very good for the gums and helps enhance the blood flow through them are herbal products such as aloe vera, Echinacea and particularly tea tree oil- especially if you soak the floss in the oil before use. But of course, in this equation in gum care is the greatest back-up of all- your dentist. They can check your gums, clean the teeth and throw any advice at you that you need to keep your gums healthy. As a footnote, healthy gums are borne out of a healthy body and this comes down to lifestyle and diet as well.

Patients with bad breath in the City of London seek advice from dentists

There are few things more embarrassing than suffering from bad breath. The worst thing about it is that sometimes you might not even notice. Some people become so used to it that are quite unaware of the fact that their breath does not smell very nice. In gaining an understanding of what is causing the condition then you can begin to understand how to deal with it and get rid of it once and for all.

Clinically bad breath is known as halitosis and it covers the whole range of unsightly smells emitting from patients’ mouths. This can mean a slight smell after a meal containing lots of garlic for example, or those who have a chronic problem with the condition whereby their breath is constantly smelly.

Bad breath is caused by certain bacteria in the mouth and so the key to beating the condition is not only removing the bacteria but ensuring that your mouth is not an ideal place for it to survive in the future. Brushing and flossing are a very important part of this of course as they ought to be getting rid of the bacteria from the mouth. Brushing your tongue can also help in this regard because bad breath bacteria often gather there.

Be careful when it comes to using mouth wash to combat bad breath. Mouth washes advertise that they beat bad breath and while they freshen the breath in the short term and kill bad breath bacteria, they leave the mouth rather dry and therefore in ideal conditions for bad breath bacteria to return once again. A chat with your City of London dentist can yield many more useful pieces of advice.

The Joys of a Dental Bridge in London

So what is a dental bridge? Well, essentially, it’s a permanent false tooth, designed to fill the space left by the loss of your own tooth and there three basic types on offer, though over time, they have evolved and become a lot more refined as new materials and techniques have been incorporated into the fitting process. A cantilever bridge is used where there are low stresses going through the mouth, generally at the front of the mouth and is anchored to one or more teeth only to one side of the new tooth. A resin bonded bridge is attached to the adjacent teeth either side of the hole with resin and wire. The more popular choice however is a fixed bridge the new tooth is molded between two crowns that is then cemented to the teeth either side of the gap. Getting a bridge is a lot simpler than having an implant, although in some cases you can combine the two for extra rigidity. Fitting normally takes a couple of visits, but your London dentist will usually fit it temporarily at first to give it a test run to iron out any problems. The only downside to having a bridge fitted is that they require extra attention to detail when it comes to cleaning to ensure bacteria is removed from under the bridge. But your dentist will advise you on how to do this and be able to supply you with small, inter-dental brushes.

The Downside of Oral Products in London

Most products that we use to keep our mouths healthy in London work wonders, better than ever before. Yet in striving to maintain our oral hygiene, we may be overdoing it and actually doing more damage. If we get the wrong brushes and toothpastes, they can be abrasive and damage the tooth’s enamel and gums, opening the doors for bacteria to flourish, leading to decay and gum disease. Other toothpastes contain ingredients that with over use, can dry up the mouths saliva- the natural fighting agent against bacteria and plaque, without which, leaves the mouth dry and very vulnerable to attack. Similarly, most mouthwashes contain alcohol- great for killing some bacteria, but again with over use, can leave the mouth bereft of the saliva it needs. One of the greatest dangers to the teeth and gums, are home tooth whitening techniques, and this is a big market right now as we clamber to get our teeth white Both whitening toothpastes and the kits themselves contain bleaching agents. Used in moderation, they work fine, but over used they can dry out the tooth enamel and the surrounding gums, doing irreversible damage. If you have any doubts about oral products, most dentists can supply you with information on how to care for your teeth sensibly.
