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.

Gummy Smiles are A Thing of the Past With Crown Lengthening

If you have a gummy smile, and you’re looking for a solution, crown lengthening may be a viable option. A gummy smile doesn’t pose dental health risks, but it can affect confidence, and crown lengthening can enhance the aesthetic of the smile at the same time as boosting self-esteem.

What exactly is a gummy smile?

A gummy smile is a term given to the appearance of the smile when the gum tissue covers a larger portion of the tooth crown than normal. This can cause more gum tissue to be visible when you smile, and the teeth to look short and small. A gummy smile doesn’t cause unpleasant symptoms like pain, but it can affect your confidence if you’re not happy with the look of your teeth.

What is crown lengthening and how could it benefit me?

Crown lengthening is a procedure, which can be used to address a gummy smile. The aim of this treatment is to make more of the tooth visible when you smile by exposing more of the crown by removing excess gum tissue. The procedure involves trimming away excess gum tissue and then restoring the tooth with a crown if it is damaged or worn. When you have treatment, more of the crown of the tooth will become visible, and as such, your teeth will look longer and larger, improving the balance of the smile. We use laser treatment to minimise discomfort and speed up the healing process.

If you have a gummy smile, and you wish you had a more attractive smile, we can help. We have procedures and tried and tested techniques that offer that can transform the appearance of the teeth to create a more balanced, even aesthetic and give you more confidence when your smile is on show. To find out more about crown lengthening, simply give us a call and book a consultation.

New study reveals alarming standards of oral health among Britain’s elite athletes

A new study has revealed alarming standards of oral health among Britain’s elite athletes.

A study conducted by researchers at University College London showed that around 50 percent of athletes suffer from dental issues that are severe enough to have a negative impact on their performance. The team identified high rates of gum disease and other oral health conditions among groups of performers, including swimmers, rowers and rugby players.

Ian Needleman, a professor from the prestigious Eastman Dental Institute at UCL, explained that high carbohydrate intake is a major contributing factor to the prevalence of dental issues among athletes. The co-author of the study also added that dry mouth is an issue in sports where heavy breathing is common, including cycling and running. Stress can also cause some athletes to vomit before a performance, which can increase the risk of acid erosion of the enamel.

The study involved around 350 athletes from nine Olympic teams, the Reading football team, England’s rugby team and cyclists from Team Sky. Athletes underwent oral health checks and assessments, and they were also asked to complete a questionnaire about the impact of dental issues on performance. Just under half of those surveyed had decay, while 77 percent had gingivitis (mild gum disease). Almost 40 percent admitted that they experienced bleeding when brushing. More than a third of participants said that dental issues had a negative effect on their performance, as well as their ability to rest and relax.

The findings of the study are interesting, especially as almost all (99%) of those involved said that they brushed their teeth twice a day. This is significantly higher than the national average of 75%, yet the risk of decay was found to be higher in athletes than the general population.

The findings of the study were presented at a European dental conference in Holland recently.

Oral Health Foundation survey reveals poor public awareness of enamel erosion

shutterstock_1039115968A new survey conducted by the Oral Health Foundation has revealed that public awareness of enamel erosion is worryingly low.

The survey, which was carried out as part of preparations for National Smile Month, shows that many people are unaware of the causes of erosion. Only 54 percent of people were aware of the damaging impact of drinking energy and sports drinks, and figures were even lower for other common causes of enamel loss, including snacking between meals, acid reflux and drinking sparkling water. Only a third of those questioned were able to list symptoms of enamel wear, including tooth thinning, heightened sensitivity, staining, enamel transparency and cracking.

The poll, which involved 2,000 people, was conducted in association with Unilever. The aim was to gauge the level of awareness, to point out potential risk factors and causes and to promote the use of Regenerate Professional Advanced Serum and Toothpaste. This product is designed to be part of a preventative approach to enamel erosion. Regenerate contains two key ingredients, calcium silicate and sodium phosphate. The formula has been developed based on NR-5 technology, which is related to bone repair. Studies show that using the serum improved the microhardness of the surface by 82% after 3 days.

Enamel erosion is a major cause of decay, and it can also contribute to an elevated risk of dental injuries and gum disease. Dentists are eager to encourage brushing with fluoride toothpaste and to discourage snacking and drinking sugary and acidic drinks. Regular dental checks are also highly recommended.

Three Reasons Why A Smile Makeover is Good for Your Teeth

shutterstock_340237085Do you feel self-conscious about your smile? Do you wish you had perfect teeth? Are your teeth worn, broken or crooked? If so, have you thought about treating yourself to a smile makeover? At Baker Street Dental, we offer a bespoke smile makeover service and we pride ourselves on producing spectacular results. If you’re thinking about taking the plunge, here are just 3 of the reasons a smile makeover is good for your teeth:

  1. Aesthetics: many people consider their smile their most important physical feature. If you’re not happy with the look of your smile, it’s natural to want to hide your teeth away whenever possible. A smile makeover can improve the appearance of your smile dramatically. This isn’t beneficial just for your confidence and wellbeing, but also for your love life and your career. Studies show that a nice smile is something potential partners and employers look for.
  2. Strength and stability: if you have chipped, broken or missing teeth, this can put your smile at risk. Broken, crumbling teeth are susceptible to damage, and gaps in the smile can increase the risk of any remaining healthy teeth moving out of position. We have a range of restorative treatments, including crowns, bridges and dentures available, and we can help to strengthen your teeth and reduce the risk of injury.
  3. Improved oral health: if you have crooked, crowded, chipped or overlapping teeth, this can make it difficult to maintain good oral hygiene. A smile makeover can help to rectify these issues, enhancing the aesthetic appeal of your smile, but also improving your dental health.

Smile makeovers are famed for their incredible aesthetic benefits, but they also offer additional advantages, which are beneficial for your oral health. If you’re interested in a smile makeover, and you’d like to find out more, call us today and we can arrange a consultation.

Leading dentist urges schools to ban sugar-laden desserts

shutterstock_611504309One of the UK’s most prominent dental figures has urged schools to ban sugary desserts in a bid to reduce rates of preventable decay.

Dean of the Faculty of Dental Surgery at the Royal College of Surgeons, Professor Michael Escudier, has encouraged schools to replace sugary puddings, such as cakes, ice cream and biscuits, with sugar-free desserts like cheese and savoury biscuits, fruit and low-sugar jelly and yoghurts. In 2016-2017, more than 34,000 children were treated in hospital under general anaesthetic for dental issues, and around 25 percent of 5-year-olds have visible signs of decay in at least one tooth.

Prof Escudier has urged schools to go ‘sugar-free’ and stop serving sweet treats at dinner times in a bid to promote good oral health and prevent children from exceeding the recommended daily intake of sugar. Dentists are also keen to get schools and nurseries involved with supervised brushing schemes. Research suggests that many children don’t brush their teeth on a regular basis, and supervised schemes could ensure that children brush at least once a day.

The news comes shortly after Public Health England launched an initiative to encourage healthy snacking. Studies claimed that a large proportion of children were exceeding the RDA of sugar through snacking alone, with many admitting to eating cakes, chocolate bars, sweets and biscuits on a daily basis. PHE is campaigning to educate parents and children about the calorie content of popular snacks, and suggests sticking to 100-calorie snacks, such as pieces of fruit.

Decay is the most common cause of hospital admissions among children in the UK, despite the fact that the vast majority of cases are preventable. The best ways to keep cavities at bay are to brush twice a day using fluoride toothpaste, to eat healthily and to visit a dentist every 6 months.

New study links dental problems to elevated diabetes risk

A new study has linked poor dental health to an elevated risk of diabetes. The findings of a research project conducted in the US suggest that dental health issues may be a risk factor for diabetes.

Lead author of the study, Raynald Samoa, from the City of Hope National Medical Centre’s Department of Diabetes, Endocrinology & Metabolism in California, explained that the condition of the teeth may be an indicator of your risk of developing diabetes. The research team analysed the impact of glucose tolerance on oral health and they found that deteriorating levels of tolerance correlated with an increased number of missing teeth. Assistant professor Samoa pointed out that the study doesn’t confirm a causal relationship, but underlines the strength of the relationship between oral health and diabetes.

To reach a conclusion, the team analysed data from 9,670 adults aged over 20. All the participants had been for a dental check during the National Health and Nutrition Survey  2009-2014. The team analysed glucose tolerance states and the body mass index (BMI). To do this, they looked at test results including fasting plasma glucose, 2-hour post-challenge glucose and haemoglobin A1c. They also took into account whether diabetes was established and how it was managed.

The research team discovered that the number of missing teeth increased as glucose tolerance decreased. In the group that had normal glucose tolerance, the proportion of people with missing teeth was 45.57%, but this rose to 67.61% in the group that had abnormal glucose tolerance and 82.87 percent in the study group with established diabetes.

The findings of the study were presented at the 100th annual meeting of the Endocrine Society in Chicago on March 19th.

Are you getting tooth care all wrong?

shutterstock_564882475Even if you clean your teeth twice a day, every day, there’s a chance that you’re not doing it right. There’s an art to brushing, and certain habits can prevent you from achieving the clean you want. To improve dental health and optimise results, dental experts have shared some common myths and helpful tips.

Brushing after eating

You may assume that the sooner you brush your teeth after eating, the better, but cleaning your teeth immediately after eating can actually do more harm than good. When you eat, your enamel softens temporarily and brushing at this point can cause it to become worn and thin. Consultant in dental public health, Derek Richards, urges patients to wait at least 10 minutes to brush after eating or drinking.

Rinsing after brushing

Many people rinse as part of their brushing routine. It comes naturally to clean your teeth, rinse and then spit. There’s nothing wrong with this pattern, but you could benefit more from skipping the rinsing step. When you rinse, this can wash away the fluoride, which is added to toothpaste to strengthen your tooth enamel.

Tooth whitening

You may think that white teeth are healthy teeth, but don’t be tempted to treat yourself to a whitening treatment that is provided by somebody without dental qualifications. Whitening is widely available at beauty salons, but this is actually illegal. Always make sure you see a registered dentist if you want whiter, brighter teeth.

Brushing takes time

Professor Damien Walmsley recently got involved in a discussion about whether you wet your brush head before cleaning or not. Some people on twitter were passionate about dampening the bristles beforehand, but Prof Walmsley, an adviser for the British Dental Association, said that all that matters is that people brush for two minutes twice a day (once before bed) using fluoride toothpaste. It doesn’t matter whether the brush is wet or dry, sticking to the basics is much more important.

Next time you go to brush your teeth, think about your daily habits and see if they need a little modification.

Researchers support the provision of preventative dental care in early stage dementia

shutterstock_553352002Researchers have backed the use of preventative dental care in the early stages of dementia, suggesting that it reduces the risk of more severe dental health problems as the disease progresses.

Robert Emmanuel, from Sussex Community NHS Foundation Trust, said that dementia has a major impact on lifestyle habits and this can affect oral health. As dementia develops, it can affect the diet and the ability to maintain a good oral hygiene routine, both of which are likely to have a negative impact on oral health. Mr Emmanuel, a special care dentist who has expertise in treating patients with late-stage dementia, said that it’s very common for patients to encounter complex oral health problems and often, these issues are untreatable.

Mr Emmanuel and his research colleague, Anne Sorensen, from Brighton and Sussex Medical School, surveyed more than 50 patients who had been diagnosed with dementia. They found that patients received dental treatment, but there was a lack of preventative measures on offer. It was uncommon for patients to be offered advice about their diet and oral hygiene tips and most had not been offered fluoride varnish treatment, which helps to strengthen the enamel and reduce the risk of cavities.

Mr Emanuel said that providing preventative care at an early stage could help to eliminate more serious dental issues later on and this would improve health and wellbeing. If patients are given the right information and support, they can use this to boost their dental health and reduce the risk of developing issues that cannot be treated or managed.
