Clean eating: Your teeth are what you eat

It’s something of a cliché, but when it comes to your teeth few would disagree with the notion that “you are what you eat”. While a solid dental routine is obviously going to cover you, if you can couple this with a diet that isn’t going to wreak havoc for your teeth then you’re onto a winner. For children, who are seemingly more susceptible to problems, this is even more crucial. This Children’s dentist in Meath has highlighted how important eating the right foods can be for infants and we have therefore created the following guide. Of course, it’s going to be relevant for any adult who wants to take care of their teeth as well. Rather than concentrate on all of the sugary foods which are renowned to be detrimental to your teeth, we’ll instead take a look at some of the foods which can actually benefit you from a dental point of view. Here goes. Carrots The old saying might be that carrots make you see in the dark, but you shouldn’t forget their power in relation to your teeth as well. While the fibre-factor with carrots is obviously important, the very fact that they are crunchy can […]

Why you must start flossing

From an early age, we are taught the importance of looking after our teeth. It becomes a daily routine to brush our teeth, something that we don’t even think about, and it’s a routine that stays with us throughout our lives. It is an important part of personal health, for teeth serve a very important purpose: without them, eating your favourite meals would be very difficult! Teeth can decay easily if they are not looked after, which results in the need to have fillings or extraction. So, what can we do to make sure we have healthy, clean teeth? We’ve already mentioned how important regular brushing is, but have you considered flossing? It is highly recommended by dentists, and many believe it should be a vital part of your daily routine. Even if you have a busy schedule – perhaps you are a full-time student, a doctor or any of many people who are hard-pressed to find the time – you really should take a little extra time to start using dental floss, and for good reason. About Plaque and Tartar While a good toothbrush is a necessity, brushing will inevitably miss some of the harder to find scraps of […]

Is it Possible to Regrow Teeth Enamel?

According to the National Institutes of Health the most prevalent form of chronic disease is tooth decay. Janet Moradian-Oldak at USC has  investigated methods to regrow tooth enamel which is a difficult undertaking as tooth enamel is not a living tissue. She collaborated with Sauma Prajapati and others to investigate matrix metalloproteinase-20, an enzyme found only in teeth which facilitate organized enamel crystal formation. Her team is the first to define the function of an enzyme for preventing protein occlusion inside a crystal. MMP-20 is released at a very early stage of enamel formation. MMP-20 chops up proteins during the crystallization of enamel. Together with other enzymes, it gets rid of ‘sludge’ so the enamel making cells in the body can add more mineral and make enamel, the hardest bioceramic in the human body. The team also looked an amelogenin-chitosan hydrogel which could repair early tooth decay by growing an enamel-like layer that reduces lesions by up to 70%. The team feels that MMP-20 can help in understanding the mechanisms of enamel formation and help in dental restoration and repair. The researchers feel that one day it may be possible for people to use an overnight mouth guard or teeth strips saturated with hydrogel to regrow enamel-like substances […]

Does the Sound of the Toothbrush Brushing Effect Quality?

A group  of researchers in Japan have discovered that how effectively we clean our teeth and how satisfied we are with quality of the brushing depends on the sound of the bristles scrubbing against the enamel.  The team used a tiny microphone in a modified toothbrush to ‘sample’ the sound being made in the mouth during brushing and to modulate it and then feed that sound back to a group of volunteers via headphones to see what effect the sound has on cleaning efficacy and satisfaction. The team found that if they manipulated the pitch, or loudness and frequency, of the brushing sound they could change the volunteers’ perception of comfort experienced and accomplishment of brushing. It was also demonstrated that if they gradually increased the frequency as teeth cleaning progressed, the volunteers felt like the process was more comfortable and at the end of brushing that their teeth were cleaner. The researchers feel that it may be possible to motivate users to perform regular brushing to help avoid them in developing cavities. It seems the researchers would like to develop a special toothbrush to manipulate the frequency of tooth brushing sounds. Right now their prototype requires someone to wear headphones. The researches think that […]

No Drill Dentistry Can Prevent Tooth Decay

Research published in Community Dentistry and Oral Epidemiology has shown that the need for fillings can be reduced by 30 to 50% through preventative oral care. This means that many previous fillings are not needed when dental decay occurs. As such a preventative approach can be beneficial when compared to current dental practices. Dentistry has been traditionally practiced with the believe that tooth decay rapidly progressed and the best way to manage it was to identify early decay and remove it quickly to prevent the tooth surface form developing cavities. After the decay is removed the tooth is restored with a filling material. Fifty years of research studies have shown that decay is not always progressive and develops more slowly than previously thought. It can take an average of four to eight years for decay to progress from the tooth’s outer layer to the tooth’s inner layer. As such quickly moving in to make a filling may not be the best approach.   The study’s author Wendell Evans and his team developed the Caries Management System which is a set of protocols which cover the specific treatment of early decay, the assessment of decay risk, and the interpretation of dental X-rays. The ‘no-drill’ treatment […]
