Scientists have grown rudimentary teeth out of the most unlikely of sources, human urine!

The results showed that urine could be used as a source of stem cells that in turn could be grown into tiny tooth-like structures. The team from China hopes the technique could be developed into a way of replacing lost teeth.

If you have a cavity, a filling is necessary to prevent further tooth decay. Fillings are placed by your dentist and can be made from a variety of different filling materials. Traditional materials include amalgam, white composite, gold, ceramic or glass ionomer materials.

Fillings are used to restore the function and appearance of your tooth so you can use it as normal. White composite fillings are increasingly becoming popular as they are a mixture of glass, quartz, silica and resin which match the colour of your natural teeth. This can improve the appearance of your smile, and no one can tell that you have any fillings.

They also chemically bond (stick) to your teeth adding strength to weakened teeth. Traditionally, dental amalgam was used as the filling material of choice, but its drawback was its unattractive metal-grey appearance. The science behind white fillings has advanced a great deal in the past few years, making them more durable and hard-wearing.

The use of dental amalgam, which contains a small amount of mercury, will be phased out over the next few years due to the negative impact of mercury on the environment. This means that dental filling materials such as white composite, glass ionomer and ceramic will become the materials of choice for cavities. Another benefit of materials such as glass ionomer cement is that it releases Fluoride into the tooth, providing the patient with added oral health benefits.

If you would like to have your existing amalgam fillings removed, a dentist can now replace them using white composite material instead. Once removed, the new filling material is then bonded onto the tooth using an ultraviolet light which hardens it in place. The material is then trimmed and shaped to match the rest of the tooth’s surface, giving your restored teeth a more natural appearance.

It depends…

It depends on the type of gum, and specifically what type of sweetener is used to flavour the gum. Chewing gum that contains sugar is bad for your teeth, whereas sugar-free gum can actually help prevent decay.

The sticky white substance that builds up on your teeth is called plaque, and consists of millions of bacteria. These bacteria need fuel to grow, and their favourite food is sugar (particularly sucrose, the refined sugar in sweets and some chewing gum). When bacteria and sugar combine in the mouth, tooth decay follows!

Chewing sugar-free gum does not provide fuel for the bacteria, and can stimulate saliva flow, which has a protective effect and helps prevent decay. Certain types of sweetener are better than others for prevention of decay – chewing gum that contains xylitol is best.

Xylitol is a naturally occurring carbohydrate that looks and tastes just like regular table sugar. It is a natural sweetener that is extracted from renewable resources such as corn cobs, and  as hardwood. Xylitol also occurs naturally in our bodies – in fact, an average size adult manufactures up to 15 grams of xylitol daily during normal metabolism. Pure xylitol is a white crystalline substance that looks and tastes like sugar. Xylitol is more expensive and less widely used that other sweeteners, and so is rarely used in most sugar-free gums. Chewing gum, mints and sweets containing xylitol can be ordered online, offers a resource for more information and links to purchase xylitol products.



How do I help my children look after their teeth?

Teaching your child, good oral care at a young age is an investment in their health that will stay with them for life. You can start by setting an example, taking good care of your own teeth sends a message that oral health is very important and anything that makes taking care of teeth fun, like brushing along with your child or letting them choose their own toothbrush, encourages good oral care.

To help your children protect their teeth and gums and greatly reduce their risk of getting cavities, teach them to follow these simple steps:

  1. Brush twice a day with fluoride toothpaste to remove plaque-the sticky film on teeth that’s the main cause of tooth decay.
  2. Floss daily to remove plaque from between your teeth and under the gum line, before it can harden into tartar. Once tartar has formed, it can only be removed by a professional cleaning.
  3. Eat a well-balanced diet that limits starchy or sugary foods, which produce plaque acids that cause tooth decay. When you do eat these foods, try to eat them with your meal instead of as a snack-the extra saliva produced during a meal helps rinse food from the mouth.
  4. Use dental products that contain fluoride, including toothpaste.
  5. Take your child to our dentist for regular check-ups.
